oc question?

[MiniDoom]

I just got an Asus P4P800E board w/pc3200 when I oc my 2.8e at 5% everything?s fine and the memory says it is running at 420 MHz. When I try anything above 5% the memory runs slow (266 MHz or so). I guess since its not pc4000 is there a way to oc more and lock my memory at 400 or 420 MHz instead of it running so slow. Thanks

Run the fsb/mem divider to 5:4 ratio.

Asus' AI OC function is so limited to just raising the fsb and setting everything on auto/default. You get better results by setting specs manually.

I have the same motherboard and pc 3200 ram. You don't HAVE to use the fixed jumps (5%, 10% ...). Select the Manual option in "AI Overclock Tuner" and then you will have a multitude of other options available 🙂. Then change the DRAM Frequency to 400 MHz or whatever you want. Hope this helps.

Thanks for the help, now running my 2.8e at 3.22. Idles at 37c with retail heat sink and fan, I'm surprised I thought the Prescott would run a little hotter.

is that what the MB says? if so, it's wrong.

Ok, now that you have overclocked your cpu, is it stable? Run the Prime95 torture test and mem86 for atleast 15 hours and see if it remains stable...

Edit: And watch those cpu temps hit the roof 😉
