1. celey tully s default voltage correctly 1 5v but i also had the S 370 DL jumper set to limit voltage 1 5 because of the default voltage were being detected 3 5v with the previous mod AN3 AK4 AJ3 insulated and AK4 gt AN11 bridge does anybody forsee any issues with the AN3 AK4 AJ3 AGI X4 AB36 X34 insulated with the ak4 lt gt aj5 bridge thanks J amp rolypoly98 SuperSlocketIII isolate those 3 pins an3 aj3 amp ak4 amp make the bridge between isol ak4 amp nonisol an1 1 No breaking pins needed here is the picture showing my mod on Abit slotket http users volja net jerman55 TualModsoc JPG Than you have to solder g35 g37 together on the back of the slotket amp also Vid pins for propper default Vcore if needed depends of mobo also try mine MS6163pro needs Vss Vid0 Vid1 for 1 45Vcore to go to max 1 75 in Bios check Intel datasheet for Vid definitions for Vcore I did not need to flash bios or reinstall my W98seLite OS For Asus P2B F 1 0A amp 1 3G Tuallie works IMHO without Bios Flashing but for others because of some multiplier bug earlier I am not sure but flashing to the latest should help to work for all Tuallies Originally posted by quarkz Hi you mean it really work I just have 2 more qns 1 when you say you connect a wire between ak4 and ak26 did you do it on the cpu or on the slotket Do it matter anyway 2 have you tried connecting ak4 to ak11 Does it work T2. 0 25V granulity down to 0 5V steps C37 is good to tie to GND and itself is a GND on the CPU too AF36 is DETECT VCC Core Det is this pin and automatically fits to GND My personal investigation is that Reserved E21 is a VSS Ground and can be tie to GND on the Slotket for better ground Q35 and Q37 is Reserved for factory use Do not use those pins at random order If you connect them both to VSS Ground your CPU may be UNLOCKED if your bios will not prevent it I mean the frequency multiplier can be out of order Just like being on AMD CPU s But that is 99 not supported by bios If you turn on and off the Computer like that or just enter into bios you will have a warning of improper frequency multiplier detected bla bla on the bios screen if you manually adjust a different CPU multiplier other than the original multiplier near the CPU highlight zone If you do not connect the Q35 and Q37 to GND this error message is not visible I still couldn t solve nor succeed on breaking the 6 5 7 7 5 8 8 5 settings Computer goes on the original multiplier regardless of the error message For Cel 1200 I adjusted 3 to 8 instead of 12 for example to cope with that error message Try if you wish on your motherboard But be carefull on that Do not push it too hard like a baby Other Reserved pins are not used Bye Have a good Summer I didn t understand Do you want to mod Asus 370 DL to run Tualatin CPU like Slot
3. The old bridging way runs the CPU with 1 8 Volts and prevents VCore adjustment which shortens the life of the CPU Maybe I need to post one more detail As I have said I have two Tualatin CPU s The bigger fan based Celeron 1100A is quite naughty When I touch the Heatsink after some time the computer restarts But not with the smaller fan based Celeron 1400 The original Intel fans are now only Aluminum and no have a black insulator paint the painted ones were better If you experience such a silly thing simply connect the heatsink to computer ground This might be related with EMI electro magnetic interference all the big fan based P4 heatsinks are connected to Computer GND for that reason You may connect a cable to the heatsink and link it to computer case or connect a thermal sensor to the CPU body which has a GND connection on one pin or under the heatsink put an isolating conductive material at various heatsinks this type was used or simply don t touch the heatsink if you experience this when the computer is on Even tough CPU protective plate has no contact with inner CPU dye this occurs at some designs I have looked at Belinassu s site and thought that the description is for BX only There are various adapters and various mobos with various chipsets I am trying to be as much as general for all 8xx and BX series with SC242 and Socket 370 The Slocket adapters and first Socket 370 mobos are build up to coppermines as you know Bu
4. UNNECESSARY In fact connecting AK4 to VCC slightly decreases Video Decoding performance 5 Converting avi to mpg I mean Other syntethic tests didn t showed a noticable change This might affect gaming performance too But I think AK4 is for managing to run the CPU only If your CPU is working without the bridge no need to connect any current to AK4 This AK4 connection way is necessary for 1 8 Volt capable boards to run ONLY If your onboard IC regulator chip is capable of providing 1 3 Volts DO NOT connect AK4 anyware Just insulate and leave it Bulding this connection to AK4 is both difficult and also gives a height change to the Socket 370 This also prevents good contact with other pins inside of the Socket 370 Some people asked me by mailing about this way For them again AK4 connection is NOT NECESSARY Ok I know there are a lot of motherboards a lot of Slotkets and various Intel amp Via chipsets As I have said connecting to my AK4 doesn t seems necessary But this is my configuration If you are something other than mine you MUST of course have to try what is good for your system I am saying Asus P3C E motherboard Asus 370 DL Slotket 7pin modding no need for AK4 bridge Your mathematical formula for your chemicals might be different Some people are asking about why I am telling amp advicing people to use 7 pin modding First of all my way is for 1 3 Volt capable motherboards Second your motherboard mu
5. and easier way for both Maybe for non tualatin based 810 and 815 chipset based ones too I couldn t test but you may try it We only need to insulate 7 pins No need to bridge AK4 on the CPU I used an Asus S370 DL adapter The pins should be insulated are AN3 AK4 AJ3 AG1 X4 AB36 and X34 To insulate you can use single wire telephone box type cable by pulling the copper wire in it to use the plastic protector for the pin isolator without widening the holes which is easier You can cut the plastic protector at the same hight of the CPU pins Don t worry they are not shot circuting Basicly insert the cable to the pin and cut it with a model knife from the upper surface of the pins After some time if you remove the CPU those plastic parts stays inside the 370 Socket I have inserted the CPU several times without doing the insulation work again and again To see this don t immidately remove the CPU close the arm run the processor some time then remove it The heat and the pin holder reshapes the plastic protector to make this happen But if you mistakenly drop the plastic parts to the 370 Socket use your model knife to push from the 4 holding guides from top by inserting the knife througly in it and hold upwards 4 of the upper part guides one by one starting from the opposite side of the removing arm Detail is here AG1 is EDGCTRL that have an indirect 50 ohm connection to VCC and X34 pin is VCC on S370 DL adapter but VTT
6. belive in fancy compounds my own measurements on another setup showed less than 1 degree difference between a silver compound and simple silicone paste Booted at once the default voltage was correctly recognized by the MB 1 5V good because the generic slocket doesn t have voltage jumpers Bumped the FSB to 112 for 1568 MHZ on the CPU runs rock stable at the default voltage Transcoded a few DVDs to DivX and SVCD great Not a single crash I doubt I ll be able to get the FSB any higher because of my SCSI card which really doesn t like more than 37MHz but I ll try in a few days Thanks everyone 2 ok I got an abit wb6 which has an 815e chipset also I bought a super slocket III Now I m looking to buy a Tualatin and mod it So far here is what I ve peiced together 1 Isolate pins AN3 AJ3 and AK4 2 Connect AK4 to the closest vtt pin either AN11 or AG1 3 Then do a Vid mod Its number 3 that I don t get if my mb can do the 1 5v do I need this mod is it chipset dependent btw here is the link to the datasheet http developer intel com design c ts 29859604 pdf Also note that section 2 8 in that datasheet it specifies that vttpwrgd should be connected to vtt and not pwred Also any hints as to which T Celeron I should get in terms of a multiplier I d like to OC it and prefer using 133 bus Thanks in advanced I ve been away awhile and catching up on recent posts I m thinking it s time for cpu elec
7. no indirect connection s If testmeter beeps and displays around 2 or 3 ohms this means it is directly connected and 10 to 50 ohms or up means it is connected via the on board components which also means it is connected too I want to add a very important thing Althogh there is a Celeron CPU running on the Asus adapter Set the CPU jumper to PIII not to Celeron PII setting is better and also necessary for both the CPU and adapter Celeron setting is for 0 18 and 0 25micron PPGA type copper and non copper Celerons Other single jumper is of course needs to be jumpered to Intel CPU By the way I advise all the modder people to try this way to prevent board blow out first The other 3 pin and bridge way is really dangerous because of having short circuit at indirectly at AG1 and directly on X34 VCC with VTT If possible reverse your running simple method type with this one Those pins are generally connected to VCC directly and indirectly for running PPGA type Celeron CPU s on adapter cards and mobos Which now are used as VTT on tualatins Intel design guidelines strictly advises not to short circuit any other type of signals with each other If you do this your CPU and mobo components may die immidately or after some time I have read so many people has killed their mobo by trying the basic method My way not only runs the CPU at its desired 35 40 C around temperature but also allows for correct VCC CPU core Voltage value as specified by Intel
8. on the tualatin CPU AJ3 and X4 are GND on S370 DL adaptor but RESET2 and GND on the CPU however AH4 and X4 are connected with each other as RESET on the S370 DL adaptor therefore X4 needs to be insulated As you know AK4 doesn t have to touch GND and thus needs to be insulated like DYN_OE on AN3 Lastly AB36 is safer to insulate because it has an indirect connection too isolating decreases the mobo and CPU temperature about 5 C degrees that V_ CMOS signal is unnecessary to connect to VTT on Tualatin CPU OK I have managed to run a Celeron 1100A at 1466MHZ very stable Mine was a tA1 stepping one and works with 1 475Volts Therefore I need to adjust the Voltage jumper to 1 5Volt over the S370 DL adapter If your CPU works with 1 5 Volts you may set it to Auto Detect 1 45Volt based P3 S type 512kB cache based Tualatin CPU s may also accept to run with Auto Detect But 1 475Volt ones MUST have to be adjusted to 1 5Volt over the S370 DL manually This is related with VRM 8 4 and 8 5 spec difference If you don t have an Asus 370 DL adapter and no have an on board Voltage adjustment jumper down to 1 5Volts then don t buy 1 475Volt CPU s or make yourself a vid pin Voltage adaper I have a Celeron 1400 CPU too which works with 1 5Volts and manage to run it with an OEM SUPER SLOCKET III type Chinese adapter but it crashed several times although I run it at normal 1400Mhz My bios suprisingly displayed a P2 1200Mhz processor on the post screen wi
9. t need to use 7 pin modding by me Because I have investigated that P3 Copper P3 Tualatin amp Celeron datasheet is false Whattt You said Yes I did Latest Explanation oe AC33 Y37 and X4 is not connected to VSS Ground they are NC AA37 and Y35 is not connected to VCC they are NC X34 and G37 is not connected to VTT they are NC too So whats up Using 7 pin modding is 5 pin modding now on 4 pin for some Slotkets Can insulate only ANI AK4 AJ3 AGI and AB36 The 5th AB36 is better for decreasing the temperature a bit on some slotkets Not for all test yours own Other 2 of 7 pin modding at X4 and X34 faces to unused pins Yes I apologise but false datasheet is not my fault Assuming the unused pins were used I have developed 7 pin modding before Tie to AK4 to VTT or VCC is optional You can build the bridge if your CPU not works as you know Well I have talked about this modding a lot at this forum and don t want to talk about it much more But I want to add more fascinating things Some people are still wondering how this modding has arised It is derived by Intel Pentium III Processor with 512KB L2 Cache Bus Terminator Design Guide called 24966101 pdf page 7 13 the 8th one is important for AG1 and 14 The AL1 pin is told to be NC but it is not used on the CPU and therefore not necessary to make any modding for this pin You can check other pins if you wish But AK36 is must have to touch the GND to disable
10. Cel is dead while testing VTT RIP Good newby boy For people having 1 8Volt tolerant Voltage Regulator IC can use Power Leap PL iP3 T only don t get sad because it has an auto regulating Voltage stage but not the Upgradewares Slot T model It only works with 1 3Volt tolerant Voltage Regulator IC having boards Check your chip if it is 1 3 Volts tolerant can buy Upgradeware Slot T model about 35 50 Power Leap PL iP3 T is selling with a Processor attached together with 1 2Gig Celeron it costs about 135 150 including the shipment price So Upgradeware is 100 cheaper and also selling without the CPU forcement Finally the research is over now If you need to build this upgrade yourself use 3 pin way plus the VCC bridge if you need or the 7 pin way which is safer and more powerful You can use VCC bridge with my 7 pin way too I do not recommend 7 pin plus VTT way because it killed my 1 4Gig Celeron I have no more Questions in my head about this self made overdrive action We hit here and there but finally reached the end If you have personal questions mail to me cemal_gurel hotmail com i used both ak26 ak4 with diode between to lower the voltage and agl ak4 VTT i m using it now on bx133 they works good using a VCC is a good choice if you don t plan to overvolt OK I have tried VCC connection with AK4 on my 7 pin modding I see no difference Therefore connecting AK4 to a VCC is completely
11. Cold Boot Voltage Selector s those 3 pins needs to be insulated too AN3 and AK4 needs to be insulated on borh of the designs Let s say I am an Intel engineer that decided to build a 0 09 micron process based P3 processor Lets say I have choosen to use 200Mhz fsb with 1 6GB sec bandwith and have decided to use PC800 RD Rams for that system Where can I start to my work for the new design of Socket 370 As I have explained above I need to choose a GND pin to use as my new RESET signal Let s say I have choosen AG5 or X5 Than if someone inserts this new CPU to a Tualatin board it won t work OK Folks thats it today for this year Have a good christmas I wish you a happy trouble free year in 2003 Bye Bye hi just to let you fellas know that after i bridged AK4 gt AN11 it booted with 3 5v default yikes good thing i went into bios first i quickly shut off and set the jumper on my S 370 DL to limit voltage to 1 5v and luckly everything is OK for past two months before that when i just have the 3 pins AN3 AK4 AJ3 insulated my bh6 S 370 DL detects my celey tully 1200 1600 correctly 1 5v and please advise B should i do the new mod I have explained the 7 pin modding with too much detail If you still can t understand what is going on then I have nothing to do hi ok i did the ak4 lt gt aj5 bridge and it works thanks W1zzard for da tip cheers btw with this mod my bh6 S 370 DL detects
12. Spajky2 Yes connecting AK4 AG1 works I ve got a 1 1A running on a CUSL2 without any problems I used a small piece of 30AWG magnet coil wire to make the bridge It sits much better flatter on the socket than using a strip of IDE cable I could ve used conductive paint but it s a pain to apply Something I noticed and it might help a few ppl trying this mod On all of the SLSZE 1 1A that I have tried 4 in all 2 Malay 2 Phil none of them was stable when I bridged AK4 and AK26 But when I change that to AK4 AN11 or AK4 AG1 shortest path they are rock solid stable Hope that helps a few of you FYI I got a new retail celeron 1 3a from NewEgg running on my old Abit BH 6 rev 1 0 using a generic Super Slocket III off of ebay It s running nice and stable with not a single crash I did the following 1 Isolated AN3 AJ3 AK4 using wire insulation 2 Connected AK4 AK26 using an insulated wire on the cpu die 3 Connected AM34 AK36 Vss to Vid25 4 Connect G35 to G37 I believe this has only been recommended for generic slockets I did not isolate any of these pins either I performed steps 1 and 2 only and and my pc would not even post I read some more and I assumed this was because Vcore was too high Good thing the Celeron has overheat circuitry I performed step 3 by sticking a small piece of insulated wire between the AM34 and AK36 holes on the slocket itself and putting the CPU in to hold it in place Reaspon generic
13. T adapter by Upgradeware Yes you can Not only with Asus S370 DL there is Asus 370 133 ABit and branded many other ones having the TVC chip on board there are no TVC chip ones too but their performance is not so good therefore look for a Slotket having a TVC chip on it Soltek Slotkets and No Name Chinase adapters like Super Slotket II not works do not try on them You only need to insulate ANI AK4 AJ3 and AG AB36 can be insulated if you have a too high temp If the mod totally not works you need to make a bridge between AK4 to VCC easy to build by connecting AK4 to AK2 nearby or VTT AK4 to AN11 but quite difficult to reach That s it khmok Actually I didn t read about dual mode support of Slot T but if your modding slotket have dual processor support like Asus S370 DL for Celeron and P3 or Asus 370 133 Only for Celerons not for P3 they can probably support dual processing according to your motherboard capabilities By the way my efforts of braking a CPU multiplier is completely absurd because I have tested it with my Celeron 1400 1300 and 1400 processors are not supported by my bios and causes that frequency multiplier allowance by bios So connecting Q35 and Q37 to GND have completely no effect on frequency multiplier I apologise again Q37 is told to be only usable for cA2 stepping based CPU s by connecting to VTT at Intel s design guide that I newly found Q35 seemingly can be connectable to GND No correspon
14. ding data is available for this one ALL also My Site info Link Wow the revival of the Thread Cemal Gurel welcome back This your turn from 7 to 5 pin mod I have to study it again amp other your stuff too when I will have time amp will again open my Warp7 machine other projects in my mind right now About the unconnected pins time ago I measured with an ohm meter amp I did not find any non connected pins on the Tuallie they are all connected to something the instrument showing but don t know exactly what Unlocking Intel HuH that would be an achievement even more than running Tuallies on older boards Heh instead of so much writing on this thread like you did you could actually make a website same amount of work I did it last month from scratch learning by the way amp you ALL are invited to visit my site at http freeweb siol net jerman55 HP Spajky htm maybe you could find some interesting stuff there also amp if you are in the bad mood just search for more or less hidden links to open in a new window under sites elements to have some fun too PS does anybody have saved the famous whole MadOnion Thread about the same topic I would like to have it but on Futuremark does not exist any more BYE I will post a very dangerous thing now that I have done but did not wished to tell about 3 months not to cause anyone to hurt This is about unlocking an Intel CPU but I couldn t succeeded As y
15. e that trick to me I was trying to run it on my sister s VC820 board But I have asked this problem to Powerleap They have replied that because of CPU ID check only P3 Tualatins can work not Celeron Tualatins So I wanted to tell it to you too I didn t made a second test with VTT but it is an obsolete thing for me now Maybe later I want to add one more thing I am using Asus Probe 21905 which was the latest and the final one Asus is not planning to continue that one and the motherboard monitor program at util page The Nidec fan was alarming all the time for about 5 10 seconds at the beginning that my CPU fan is not working Later it continues normally giving the information If you are using Asus Probe this is a bad thing But Nidec fan and the cooler is not too bad Yes Sanyo works better but Nidec has a great big cooler with a silent and big fan I am running mine at 1 6Gig so you can also use this fan but a bigger weighted cooler is much better You may also look for copper bottomed ones for safety Actually beeping about 5 10 sec from a Cooler is not a good thing if you are Overclocking your system But if you can not manage to find a good cooler at your area you may only think of replacing the Nidec fan only Iam saying this for my system again of course If your motherboard alerting program works better than mine you may continue your way normally Hey Boys I came back First thing I want to tell to you is you don
16. e to buy one of those adapters later those pins may be necessary for them to properly run Depends on you I am not advising to braek any pins and if possible do not give damage to adapters by removing it s contacts There are shortage of those adapters now Like I did someone later prepares a better CPU upgrade kit or a better CPU upgrade Cyrix or Intel Overdrive so those adapters are necessary again But if you need to choose remove CPU pins instead of playing with adapters But what happens if you later find a Tualatin board Think twice Falkentyne asks how is powerleap adapter working Well first of all there are 3 types of Power Leap adapters for SC242 s The one which is best is PL iP3 T only for SC242 s Others must have to be used with Slockets that PL 370 T with an additional voltage supply connection and PL NEO T But this one is not a good one It has 2 less pins on CPU side and 10 less pins at Socket 370 side All the models works different than each other Best one for SC242 only model internally adjusts the CPU Vcore and provides the necessary supply voltage by a 4 pin floppy connection PL 370 T for Slot 370 also manages that but needs a 1 5 Volt CPU for 100 compatibility Lately 1 33 and 1 4 Ghz this one is very new and available only with tA 1 stepping currently 256K cache based ones are 1 5Volt All 512K cache ones are 1 45 Volts Probably all the copper based Slot 370 boards may run them at 1 5 Volt with this type ada
17. ent You need to be a computer engineer to understand that I am a Radio amp TV amp Film graduate but my father is an electronics engineer who graduated from Constanz Germany therefore I know You are asking that is Power leap 100 compatible or not Actually none of the designs can give 100 compatibility if your board is not a Tualatin board Because Tualatins use differential signals to manage to run the CPU dependable at high frequencies No one can possibly provide that unless you have a compatible board We are only managing it with a single side way The other lane can not be used on non Tualatins It is not possible if you have no double lane managing substructure on your mobo Intel managed that by reducing the Voltage at that way to prevent EMI electro magnetic interference We are completely not using PWRGOOD signal because of not having such system double lane to inform as ready to the Computer system GTL bus is the general signal name for all the 1 25Volt signals including the VTT signals as far as I know Yes we have no lesser any type of signals lower than 1 5Volts on board Brief explanation of 7 pin isolation removal method New way prevents extreme 1 8Volt only Vcore and gives adjustment opportunity starting from 1 5Volts up to 3 5Volts Easier to build without bridging on the CPU Generates lesser heat allows better overclockability Prevents Slotket short circuit for tualatins Protects mobo s m
18. hanks alot l yes it matter do the bridge on the cpu not in the socket 2 i tryed on bx133 but it didn t work so i used ak4 26 also on be6 try ak4 an11 anyway if it work it should be better than ak4 26 2 I tried both bridges and must say that the ak4 an11 is more stable Hey Here are the chips can support Tualatin and nonCopper amp Tualatin HIP6004 CB HIP6004B CB HIP6019B CB SC1185 amp SC1185A US3007 CW Supports at least Coppermine and can support Tualatin with Powerleap and Upgradeware adapters HIP6004A HIP6019 CB only supports 0 25micron processors upto 600Mhz nonCopper amp Tualatin With these even Powerleap and Upgradeware adapters can not support throughly or can not Because they can lower the VCC Voltage as low as 1 8Volts only I have found two more good chips supporting Coppermine amp Tualatin CPU s Those are HIP6020 CB and HIP6021A CB There might be more chips that I know Don t ask me please Simply goto www msn com or others and search for it Do not put the pharantesis that have I put They are for easy understanding only Hi Again Someone asked me before about the safest bridge between AK4 with VCC AJ5 AK2 AM4 or AK4 with VTT AN11 or AK4 with AK26 PWRGD this one seems not a good choice but first try VCC than this one and finally VTT I have tested VCC and VTT deeply and the winner is VCC YES use VCC insted of VTT for safety Actually my 1 4Gig
19. ly impossible to re solder because the capacitor parts are very sensitive The metal attached 8 legs are separating from the body and become unusable if you want to re solder them again For that reason there is no way to return CPU keeps running if you won t remove all the caps I later removed all the caps to see a successive result but this caused CPU to die Therefore DO NOT try to remove all of the caps if you wish to test it Again this explanation is only for Professionals who are familiar for those types of work and talented amp capable of using my hint to develop with their superior knowledge for a finally successive unlocking method Maybe a writing on Computer bios or other pin connection ways I actually traced and find 3 reserved pins such as E21 Ground Q35 Very likely Ground and Q37 VTT but connecting to VTT only advised for cA2 type P3 CPU s such as 800EB etc But those pins have no effect on unlocking success that I have seen myself Other reserved pins are not used They were left blank unused If you know good professionals around you please tell them about my attemts on unlocking an Intel CPU They may catch attention on my way maybe
20. olts Don t try to be an engineer by repeatedly tring so many combinations There are sometimes other resons which can not be handled Try their way or this one with an Asus S370 DL More attempts may make you upset by causing handicaps Well Well Well I have decided to explain the difference between the AK4 to AK26 PWRGOOD or AJ5 VCC or AN11 VTT compared with AH4 RESET and X4 RESET Intel has build 3 generations for Socket 370 To protect their design they needed to replace the paths of some of the pins The most important protective circuitry here is the 3 RESET pins X4 was the 0 25 micron process RESET pin AH4 was the 0 18 micron Coppermine process pin and finally AJ3 was the 0 13 micron Tualatin process pin If one of those reset pins touchs the GND computer understands that an unappropriate processor has been populated therefore the Processor VCore has been cut They prevented to run the CPU What the bridging method manages is they were by passing this system by giving current to AK4 pin therefore the processor gets the VCore and thereby works again I have corrected this by finding the trick Others therefore needed to build Cold Boot Voltage Selectors to manage to give desired VCores to the CPU I have also searched that there are dangerous pins that cause short circuit at AG1 AB36 X34 THOSE 3 PINS CAN BE INSULATED WITH THE OTHER BRIDGING WAY TOO I mean if you are using AK4 connection on CPU and or using
21. osfets and board blow out Can use every cooler box cooler or yours favorite one Consumes less power protects power supply Protects mobo capacitors and resistors Finally protects your wallet If you feed VITTPWRGD with VCC you of course get 1 5Volt or whatever you adjust for VCC from the motherboard Some others tried that from VTT being all the time 1 5Volts too 1 8Volt supply is possible with the so called famous bridge AK26 PWRGOOD with AK4 VTTPWRGD You might be right being unsuccesful because of using a different Slotket I have tried a Chinase Slotket and become unsuccesful too I can advise you to try with an Asus 370 DL If you become unsuccesful after your attempts I want to add one more thing because of others run their designs with short circuits they needed more power from their power supplies and fixed this issue by increasing the VCore The system vasted some amount of power from those shorts I don t advice increasing the VCore too much because we don t have resource wasting shorts now therefore incresing the VCore directly sends more power to the CPU that can be imagined 1 5 and 1 55Volts are enough to run at original speed 1 6 and up might be used for extreme overclockers But definitely not more than 1 7 Volts At that case they become first generation Coppers that if so Intel does not necessarily need to change chipsets and CPU core s accordingly I know there are fanatics who tried upto 2 0 V
22. ou know there are 8 legged Capacitors in the bottom center of P3 Tualatin and Celerons There are 12 capacitors on tA1 and 9 capacitors on tB1 revisions For 12 cap tA1 the centered 8 of them are connected to VCC and the outer 4 of them are connected to VTT For 9 cap tB1 the centered 6 of them are VCC and the outer 3 of them are VTT again What I have did to my tA1 Celeron 1400 is a mad thing I have removed 3 caps under the CPU but mistakenly I am sometims absent minded I have removed the opposite way ones Ha Ha Ha the ones looking to V and T line pins 32 37 What this caused In the bios screen the CPU multiplier now moves from 3 to 8 As you know 3 for PIII 300 processors 8 for PIII 800E processors etc But even though the controllable menu CPU runs at 1400Mhz still I have suspected about the originality of the 1400Mhz CPU in the beginning and assumed 1300Mhz can also be like that because my bios can not handle over 12 multiplier A couple of weeks ago I have bought a Cel 1300 and see that it s CPU multiplier is constant not allows 3 to 8 That means my faulty removal of 3 caps was causing the allowance of frequency multiplier Ta Taaa I actually did not wished to post about this because of being dangerous and in fact unsuccesful unlocking experience But for computer engineers and great professional CPU fanatics may go on and trace it possibly to derive and find the successive way may be If the caps once removed they are near
