Massman Posted January 30, 2010 Author Posted January 30, 2010 These are modifications for other boards than the MSI and Gigabyte. I haven't tested them myself just yet, so PLEASE DON'T TEST if you don't want to. I don't guarantee these work, I'm just following the same methodology. PLEASE confirm if it work! Asus M3F Quote
Evocarlos Posted January 30, 2010 Posted January 30, 2010 gd85 cold boot mod vid ovp is easy on the upi chips Quote
Massman Posted January 30, 2010 Author Posted January 30, 2010 Without modification: coldbug ~-110°C Then tried 255MHz ... not at -95°C, not at -100°C, but works at -105°C Max bclk was 260MHz, but not cold enough. Now board warming up and will see how it works after coldbug modification. Quote
TheKarmakazi Posted January 30, 2010 Posted January 30, 2010 if only all cb's were as easy to get rid of as taping one pin Quote
Massman Posted January 30, 2010 Author Posted January 30, 2010 Same issue again with the UD6. Seems like I'm missing something :-/ Quote
miahallen Posted January 31, 2010 Posted January 31, 2010 (edited) Didn't work on my P55A-UD3R Massman...I tried taping the pin but the system failed to post...just power cycle over and over. Removed the tape and it posted just fine I'll try removing the resistor... Edited January 31, 2010 by miahallen Quote
miahallen Posted January 31, 2010 Posted January 31, 2010 Well...I tried shorting the resistor...but CB didn't change Quote
HanoiOverclockingClub Posted January 31, 2010 Posted January 31, 2010 Here is P55-GD80. Can someone let me know where is FB? Is it the same point as P55-GD85? Thanks you. Quote
miahallen Posted January 31, 2010 Posted January 31, 2010 (edited) Removing the resistor cause the system to fail to post... so I tried shorting the contacts with a proper solder job...and it worked Quick assesment shows new CBB at -145C and CB at -170C (or so ) Edited January 31, 2010 by miahallen Quote
BenchBros Posted January 31, 2010 Posted January 31, 2010 (edited) on P55-UD5 it is this Resistor: http://www.abload.de/img/p55-ud5f69o.jpg €: Mod confirmed works fine on GB P55-UD5 before Mod -80° Board-CBB and now I have a CPU-CBB @ -110° Edited January 31, 2010 by BenchBros Quote
Massman Posted January 31, 2010 Author Posted January 31, 2010 so I tried shorting the contacts with a proper solder job...and it worked Yeah, sorry, that's actually the most important part: either you remove the resistor or not, connecting both 'ends' is the message. I've updated the opening post. Quote
Massman Posted January 31, 2010 Author Posted January 31, 2010 FB = pin8, just find a cap or resistor connected to this pin and you found FB Quote
Evocarlos Posted January 31, 2010 Posted January 31, 2010 same controller but diffrent layout for soldering point i have used your image and marked the 2 points you can use with out having one i cant say what vr to use but if its anything like the gd-85 it would be 20k or 50k vr Quote
tiborrr Posted January 31, 2010 Posted January 31, 2010 Thanks Masbo! Will try this on Sabertooth 55i soon! Quote
tiborrr Posted January 31, 2010 Posted January 31, 2010 can you source sabertooth mod? i'm willing to try it. Quote
tiborrr Posted January 31, 2010 Posted January 31, 2010 Cool, thank you, I'll have a look at it. Looks like I'll have to strip insulation rubber Quote
Crew stummerwinter Posted January 31, 2010 Crew Posted January 31, 2010 More mods here, confirmed by Christian from Asus: http://awardfabrik.de/forum/showthread.php?t=7609 Quote

Massman Posted February 1, 2010 Author Posted February 1, 2010 though there is some way to fix clarkdale 's cold boot and bugif your using LN2, then could help you down to lower temperature the first mod is short PEG_Rbias. that pin you can find one cpu backside and motherboard, so you just need to choose which one is easier for you tool: pencil ------- most of time not work, casue you didn't do it very well silver pen -------------esier solder ------------only work on motherboard mod, on cpu its too dangerous. CPU Pin mod short 2 pins (red spot) P55A-UD7 P55A-UD6, P55-UD6, P55(A)-UD6© P55A-UD5,P55-UD5 H55-UD3H P55M-UD2, P55-UD3L, P55-US3L, P55-USB3, P55A-UD4P, P55A-UD4, P55A-UD3P P55A-UD4P, P55A-UD4, P55A-UD3P, P55A-UD3R, P55A-UD3, P55-UD4,P55-UD3, P55-UD3P, P55-UD3L-TPM P55-UD4P, P55-UD3R, P55M-UD4, P55-UD3L, for other board belonds to UD3/P series, should be the same Source: XtremeSystems Quote
TiN Posted February 3, 2010 Posted February 3, 2010 PEG_RBIAS present on 1366 platform too, but related to IOH. If anybody want try I can show Tylersburg chipsets have PE0RBIAS (ball AN34), PE1RBIAS (ball AN13). these are hooked to GND with same 750ohm resistor. But coz 1366 IOH is extra chip, not part of CPU package it may not be related to CB/CBB's. Quote

Lets see, I might try... Quote
