My System Specs

Default 920 OC Voltage questions

Alright gentlemen, having run my 920 up to a 185 bClk, I get some stability issues above that. This being my first i7, I'm wondering what your input is on max voltages for 24/7 use. And I mean 24/7, I fold. Keep in mind the chip is under water, so temps aren't an issue, at least yet.

What are your max comfortable voltages for vCore? CPU PLL? CPU Vtt? QPI PLL? IO voltages?

I may have hit the max bClk for this mobo, but I hope not.

Thanks for your input.

My System Specs

Default

Vcore 1.45
PLL: 1.4?
vtt? Was always on Auto for me.
QPI 1.45, same as vcore
io Auto

Vram: 1.65V MAX.

Also make sure your CPU Uncore frequency is at least twice the speed of your ram. Drop the multi to 19, leave Turbo On. Double-check the QPI and don't overclock too high - stock is 4.8GT/s.

PLL Min voltage is 1.8v. Not sure about max, I run mine on auto...

Not sure about the EVGA board, but when I set my own multiplier (mine is 19) I don't get to choose whether or not turbo is on (assuming that it's off).

What clock are you going for Gord? Most people are using a 200BLCK, I'm 200x19 and it seems to be working very well.

Thanks guys. I was trying to hit a 200 BCLK, but wasn't sure how hard I could push this thing. More tweaking fun tonight. I'll try dropping the multi to 19x. I believe Turbo is always on with the EVGA's, which would hit my 4.0 Ghz.
