Really getting stumped... Hoping the gurus here can help me out.
I have recently had success overclocking my system from From 2.6 to 3.2 Ghz. (FSB from 333 to 400)
E6750
Asus P5KC (0701 Bios)
Crucial Ballistix (800Mhz 4,4,4,10)
CPU Voltage Auto
Stock Vdimm Auto
P182
Corsair 520 PSU
8800 GT
Zalman Fan
Core temps an a smidge above where they were at at stock speed. (speedfan and the crapy asus temp probe report about 13-22 Celcius at Load, with the cores in the low 30s.) It is rock solid stabe without any voltage increases and the temps are really low.
Now if I want to go higher than this (3.3GHz ,3.4 or 3.5) I start to run into problems... Even if I:
1. Increase voltage to 1.5
2. Increase VDIMM to 2.2
3. Relax the Ram timinings to 6-6-6-20
System loads up fine, but prime fails after a few minutes during torture test. I have a sneaky suspicion it is the RAM given that it usually fails during the RAM intensive portion of the test and the temps are all very low even when i bump up the voltage.
Is it likelly that my ram, which runs at very well at 800, 4,4,4,10 cannot even do 825,6,6,6,20?
I have heard elsewhere that the P5KC is finicky with the secondary timings and that asus default timing loads are quite aggresive. Could this be impacting things?
I am new to this, but i find it hard to understand how with no increase in voltages, i can overclock 20%, yet if I push voltages up and relax timings, I cannot even hit 30%. Would love some advice.
Cheers, and thanks to all who have contributed on this forum getting me to 20%
