Hit a wall at 3.3Ghz

post #1 of 3
Thread Starter 
Currently at 24% oc at 3.3Ghz. Seems like it should go higher. Increasing voltages (cpu and memory) seems to not add stability. My acid test for stability is two instances of Prime95 testing exponents - I've found that this is a more stressful test than even the torture test.

The mobo I'm using changes the RAM frequency as I increase the cpu frequency. My desire is to keep cpu and memory in sync at 1:1, so with the cpu at stock frequency should I set the memory at 533Mhz even though it's DDR2 800, and let the mobo increase the frequency as I increase the cpu frequency?

I'm not real experienced at oc'ing, but I believe this combination should be capable of a higher 'safe' oc. I'm not interested in obtaining a maximum overclock, but it does help iteration times when testing Prime95 exponents.

Any suggestions would be most appreciated!

You really should use a memory divider. Your CPU can go much further, but your memory is holding you back. Memory and CPU should be overclocked separately.
So, put your memory on a divider, continue to oc your CPU, and soon enough, your memory will be back at 400MHz.

Can't seem to find where to do that in the BIOS?

And, when my cpu is set at stock frequency (2.66Ghz), do I need to set my memory at 533Mhz, and let the BIOS auto increase it as I increase the cpu frequency?
