Core i7/X58 Overclocking Thread

[Xello]

Ok, I'll try 1.4 Qpi/Vtt and if that doesn't work, I'll come back and post my system specs as well as bios settings. Hopefully, someone out there will be able to tell me where I've gone wrong.

I've had to go back down to 195 - 200 bclk since I really didn't like those voltages.

Yeah i wouldn't go over 1.5v while testing max qpi / bclk etc. One reason is because that's a sort of limit i set myself based on what i've seen and another is that i already know i can get up to 216bclk with 1.44v stable, and that i won't be wanting to go that high on my final OC anyway.

Really have to play your own game with voltages, for example i'm stable @ 4.3ghz with 1.456v, but i now know i'm also stable @ 4.2ghz with 1.37v (perhaps less, not finished testing). So there's no way i'm going to set a whole .08v higher for only 100mhz extra when the clock is already so high that it won't make a difference to me personally.

Please do post your bios settings though, can't figure out why you need such ridiculous VTT. When i started to find max bclk all i did was:

Bclock 200 (my starting point as i knew it was stable already)
CPU Multiplier 12x
Uncore Multiplier 12x
QPI Multiplier 18x (36x in bios)
Memory Multiplier 6x
Vcore 1.275v
VTT 1.46v
Vdimm 1.64v

Then i started raising bclk until i hit walls. Under this setting your roof is only going to be how high your QPI clock tops out - meant to be around or just under 4ghz.
