I've been having bad experiences getting stable at 4.0Ghz w/ my i7 930. So I decided to try to force my RAM to be as slow as possible (1147Mhz). Now I can get stable w/ 1.225vcore, 1.25QPI.

Here's my BIOS relevant settings

vcore 1.225
qpi 1.25
DIMM 1.65
pll 1.88
ich 1.2
ioh 1.18

RAM timing:
8-8-8-24-2T

When I change it to 1517Mhz (something like that), it becomes unstable at even 1.275vcore and 1.275QPI. I don't really know why. My uncore ratio is the lowest possible from RAM clocks (2x). Is the OCZ gold series really bad that they won't even run at specs?

I'm also having this problem.

My CPU is stable over 24h Prime95 small FFT, but it would simply not pass a couple hours of Prime95 Blend. The error is "rouding error". I can't pass LinX/IBT maximum memory usage, never more than 2 runs.

This guide is saying that this is memory related.
It suggested to rise IOH a notch or two.
I'll report back when I'm done with CPU voltage testing

Vcore = 1.268750
QPi = 1.23125
IOH = 1.20
ICH = 1.1
BCLK = 191
RAtio = 21x

Memory : OCZ3G1600LV6GK
Timings : 8-8-8-24-auto-1T
VDRAM = 1.65
This memory passed 3 memtest runs @ my current settings (memory speed is 1531 Mh)

shuffle and reseat your rams, use auto for pll ich ioh, if this doesn't work run memtest. Alot of ocz gold has issues
