Core i7/X58 Overclocking Thread

[Bludd]

I am not an experienced overclocker, but I am not a complete newbie. That said, I'm not really comfortable with cranking the voltages.

I would like someone to review my settings:

BCLK 160 (x20 = 3.2 GHz, turbo on, HT on)
CPU voltage 1.3
QPI/DRAM core (uncore, I think) 1.33750
CPU PLL 1.88
ICH, IOH, ICH PCIe and IOH PCIe are at default 1.1, 1.1, 1.5 and 1.5 respectively
DRAM bus 1.64

Should I raise/lower any of these? If you need more info on my system, please let me know.

I just downloaded the latest version of CPUID HW Monitor http://www.cpuid.com/hwmonitor.php (version 1.13) and it tells me my DRAM bus voltage is 1.67. I am concerned because of the 1.65 limit I've been reading about and even though I have heard people say that if QPI/DRAM is within 0.5 V of DRAM bus voltage, everything should be OK, I haven't found any documentation about it at Intel's websites.

Is HWMonitor correct? Is my BIOS setting correct? I don't want to end up with a CPU that dies on me early.

Edit: Okay, I am officially a chicken: I have reduced CPU PLL voltage to 1.82, CPU voltage to 1.28750, QPI/DRAM uncore voltage to 1.28750. (fold as in give in )

Edit2: That wasn't stable so I upped CPU PLL to 1.84 and QPI/DRAM uncore voltage to 1.3 but I would ideally like to have it under 1.3
