Gigabyte MA770-DS3 cpu voltages

post #1 of 8
Thread Starter 
Ive just installed my Gigabyte MA770-DS3 mobo and a new 9850 Phenom with the expectation of overclocking it.

Going into the bios cpu voltages option it only lets me increase the voltage by 0.1v maximum, so thats a 1.4v at most! Ive got a vapochill and wanted to take the voltage to about 1.5v for a high overclock as Ive read people have got the cpu to 3Ghz at just over 1.5v.

Does anyone else with this mobo have the same/higher voltage options?

try updating to the latest bios and see if that lets you increase the voltage a little more.

You can do pinmod (wiremod) on your CPU to get 1,55V. See there:

It has the latest bios update f4, but still no voltage increase. In fact I am unable to get any overclocking on it at all.

I have a 9850 phenom, Ati 2900 pro, 4gb 1066 mhz OCZ reaper and the system runs unstable/BSOD if I put the DDR2 to 800mhz or 1066mhz! Even with the voltage set to 2.1v!

When I use AMD overdrive to autoclock the cpu the machine just freezes, if I go into bios and overclock SLIGHTLY I get BSOD/crashes - even with a voltage increase!

When I go into Ati overdrive and autoclock the Ati 2900pro it does overclock to 858/900mhz but when I click 'apply' the clocks are still reading 507/514mhz but GPU-Z says 600/600!

It just doesnt work, I even get a few crashes/BSOD when not overclocking. I have a dual boot and Vista 64 is the worst but XP 64 is a bit more stable.

I have the same mb and no problems overclocking.
Remember to diasble AMD Cool&Quiet.
When in bios Press ctrl+F1 for the advanced bios features.

Maybe you have a corrupt bios?

Gigabyte was never officially confirm that they support x4 9850 with their 770 or 780G board, althrough they work, perhaps the board isn't meant of these 125w cpus supposely,

I'm about to buy the simular setup, can someone confirm this?

770 & 780G based boards can hardly provide 125W to the CPU. And if you want to OC 9850 then TDP will rise over 125W and these boards surely will have stability problem.

cool , make sense got it,

how about just drop a 9850 into test it, i shouldn't blow anything should I ?since the official site says it does support the 9750 125w, that should mean the motherboard is design to handle 125w cpu at at least it's default am I right?

cause I purchased a DFI 790FX board but i's on the way and the 9850 i'm getting is used so I need to test it (well the guy never used it , and he doesn't own dekstop computer something about it's a gift) just in case.
