Gigabyte GA-P67A-UD5 Discussion Thread

[FL00D]

Hi C-N,

My PC specs are as follows:

GA P67A-UD4-B3
2600K @ 4.5GHz, @ 1.35V (=1.332V Load), LLC Enabled, energy saving features turned off, Turbo OFF, R-TRCinOS OFF, HT ON.
8GB HyperX Grey @ 1600MHz 1.5V (=1.548V)
2xSapphire 6950 2GB CF
Corsair HX750

I read in one of your posts that for CrossFire PCH core should be at about 1.14V to prevent the graphics driver crashing.

Well, I have had graphics driver crashes (...video driver has stopped responding... then BSoD: 0x116 Video TDR Error) but never under load. I can run 3DMark11, Haven, games etc. Unfortunately, the new Catalyst drivers do cause BSoDs rather often for several people and now I'm not sure if that 3 crashes I have had were brought about by the driver or the low PCH core.

What do you think? Shall I raise the PCH core? I'm a bit worried since I don't know what else would that affect. In fact, I've never read about increasing the PCH core before.
