P5N32-E SLI and Q6600 O/C problem.

Ok I overclocked my system with these settings changed:

Bios: 12.03 (Also tried 12.05 but has problems getting past 2.6GHz)
FSB:Memory ratio 5:6
FSB: 1000MHz goes to 1333MHz
Memory 800MHz goes to 880MHz
CPU 2.4GHz goes to 3.0GHz

All voltages are on auto except the memory which is on 2.2V so I can overclock the latencys to 4 3 3 15 2T

This is fine, runs like a dream and boots ok 50/50 of the time.

However occassionally when I boot up the monitor shows a black screen = no signal = didnt boot properly, on a restart its fine again. Also sometimes the control panel doesnt appear, again a restart fixes this.

So I though its probably not quite stable. So I've tried the following:

Increasing the latencys on the memory to 4 4 4 15 2T and 5 5 5 15 2T
Unlinking the FSB:Memory ratio so the memory goes back to 800MHz
Increasing the CPU, CPU VTT, NB and SB voltages.

The only thing that seems to get rid of the two problems is getting rid of the overclock.

Doesnt change anything. So any recommendations? Ideas? Or any voltages I should use?

I also need a program for a stress test, anyone know of any good ones that work with Vista 64bit?


If I can sort my processor I may overclock my memory to 1100MHz @ 4 4 4 12 2T

Do you have all the spread specturms disabled and also the SLI memory disabled?
PCIEX16 I MHZ 100
PCIEX16 2 MHZ 100
PCIEX16 3 MHZ 100
SPP<->MCP REF CLOCK, MHZ 200
SPREAD SPECTURM COTROL ALL DISABLED
SLI BROADCAST APERTURE DISABLED
NVIDIA GPU EX DISABLED
SLI MEMORY DISABLED

Yep

Thanks for quick reply

I know they just released a new beta bios 1302. Everything I've been reading about this board says that it is not very good for overclocking a Quad. That's why when I upgrade to a Q9550 in Jan.08 I'll probably change mobo's. I will go with a P35 and drop the SLI.
