Hi everyone,

Hope to solve here my RAM OC issues on P5B Dlx so any kind help would be greatly welcome. My system specs are shown in my

signature.

First, I'd like to point out my BIOS settings:

PCI-E frequency - locked at 100 mhz
PCI clock at 33.33 mgh
C1E - disabled
MaxCPUID - disabled
CPUTM - enabled
PECI - disabled
Static read control - disabled
Execute disable bit - enabled
Spread spectrum - disabled
NB Vcore - 1.45V
SB Vcore - 1.6V
FSB Termination - 1.4V
Vcore - I set it depending on the CPU speed, for instance, it is Prime and TAT stable at 3400 mgh@1.45V set in BIOS.
CPU Multi lowered to 8

The problem is that my RAM is Prime unstable (in Large in-place FFTs test) and reports errors almost immediately even at the

ridiculous 415 Mgh@2.1V and the loosest possible timings set in BIOS. 2.25V did not help. On the other hand, I have had no issues

so far playing for 3-4 hours games like FEAR, CoJ, benchmarking (3DMarks, Super Pi 32M) or any other kind of applications.

I've been trying different voltage, timing and subtiming combinations (5-5-5-18(15)-42(25)-10(3)-10(11)-10(5)-25(14), including those

set by SPD, set BIOS by defalut and set afterwards manually the default (sub)timings suggested by MemSet. But that did not help

either.
BTW, when setting the timings by SPD and OC-ing FSB, the CPU-Z and Everest both report by some unknown reason 4-4-4-12.

Even tried FSB 380x9@760 mgh (1:1, 2.0V, timings set by SPD or manually) but Prime still reports RAM errors in 20-30 sec.

I cannot believe that my RAM is that crappy and have a comprehension that the solution lies in some subtiming or other BIOS setting I

have no clue of. Or might it be anything else?

Thanks.
