My bench:
OEM Intel E8500
OCZ DDR3 PC3-14400 1800MHz DDR3 CL 8-8-8-24 1.95 Volts
Asus Striker II Extreme - 0704 (no corruption problems)

I have been testing all kind of different voltage settings for a week and I just cant get it 100% stable.
When I run 1.48 on NB it does calculate 1M SuperPi, but prime95 is an instant crash.
With 1.50 on NB (1.60 on SB) I can run prime95 for like 20min then it gives calculation error.
On all settings Crysis does crash in 5-30min - never got more then 30min of gameplay.

My most "stable" settings to date:

9.5 x 450 - 1800
CPU Voltage = 1.45
Loadline Calibration = disabled,
CPU PLL Voltage = 1.58
CPU VTT Voltage = 1.34
Memory Voltage = 1.96v
NB Core Voltage = 1.50v
SB Core Voltage = 1.60v
CPU GTL REF0 Ratio = Auto or +42
CPU GTL REF1 Ratio = Auto or +39
CPU GTL REF2 Ratio = Auto or +39
CPU GTL REF3 Ratio = Auto or +42
NB GTL REF Ratio = +40

I have h2o on MB and CPU and general quite nice air cooling, still NB gets to 50C after boot.

What can I do to get it stable? I have tried like 40 configurations on volts and FSB but it just never stable.
What is the path to test it and to find the problem? You can say I am a bit of a noob on Intel OC

Can it be bad MB or it just stupid me?

thx
I'm no expert but here's what I would do based on reading this thread...

It sounds silly but did you try offsets of the FSB...like 1802 or 1810. I could not get 1700 working a few bios ago and then I set it to 1702 and pow everthing fine and stable.

I have tried 1800 myself and cannot get stable there. I'm stuck at 1760 right now.

If that deosn't work...I would look at the RAM settings. P1 P2 to auto, try 1T instead of 2T, relax the timings, someone said the white slots are better than the blue slots... maybe worth a try.
