GIGABYTE P55/H55 Cold boot / Bug fix mod

[hicookie]

though there is some way to fix clarkdale 's cold boot and bug
if 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(C)


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

Very nice...thanks master cookie

[M.Beier]

Thanks for sharring....
So that is where all the gease goes

[dinos22]

nice

[Mad222]

I'll try both
HoHo....it's fun
Thx again Hicookie, you never let us down, man !

[Charles Wirth]

conductive on mobo now, testing.

[MaJ0r]

Thanks

[stabias]

on MB - short pins too?

[Moso]

Thanks for sharring.

[hicookie]

on MB, just short the resistor.

[siavash_shojaee]

tanx hicookie can i use HP PEN?

[KanGaXx]

Thanks

[tranngocminh]

I did this mod for H55M-UD2H and P55-UD4P. Nice done, tks Master HiCookie

[dinos22]

nice photo Hiwa
im sure it will be helpful to some members

guys let us know what sort of difference you are getting with the mod off and on

[Jor3lBR]

One question: do you need to do the cpu (clarkdale pinmod on pic #1) + the mobo mod for it to work?

[BaRaN]

thanks

but there is problem with only one pic the p55-ud6 photo remove from server!!!
any body have that pic?

[Jor3lBR]

thanks

The p55-ud6 is the one on post #11.

[BaRaN]

The p55-ud6 is the one on post #11.

i have p55a-ud6(C) and the back side is the same of ud7 but is the modding of ud7 should set on ud6?

[S_A_V]

i have p55a-ud6(C) and the back side is the same of ud7 but is the modding of ud7 should set on ud6?

Yes, P55A-UD6 that looks like UD7 on back side can be modded the same way as UD7. I done this mod on such board and can bench my i5-670 with -160C.

One question: do you need to do the cpu (clarkdale pinmod on pic #1) + the mobo mod for it to work?

I only used MB CBB/CB mod.
Before: CB -85*
After: CB - 155*.

[hicookie]

One question: do you need to do the cpu (clarkdale pinmod on pic #1) + the mobo mod for it to work?

just pick one to mod , cpu or mobo.

if you done on CPU, then you can put it on any board without mod to fix cold bug.

if you done on board, then you don't need to mod on cpu.
every cpu on that mod you mod could be fixing cold bug.

[hicookie]

I think some people get problem with soldering 0402 tiny resistor.
you can solder the side which measure 0.7k, and connect to any ground
or you can use my way to switch







a brief test with 530, after mod, there is no cold bug with this chip
but Bclk end at 264.

[hicookie]

continue the thread;

if guys you loose the oringinal resistor
without resistor will leave 2 empty points
just short them. for CB mod no need the ringinal resistor work the same.

[KanGaXx]

eheh my resistor is destroyed i 've short the 2 empty hole and work fine. You think this lose bclk perfomance or it's the same ?
