I can't clock more than 3.5 ghz!

[The Pentium Guy]

hey,

I got a new heatsink, zalman 7700 AlCu, in hopes that I would be able to overclock more than with my stock cooler.

With my stock heatsink (ASUS P4P800-e Deluxe, pentium 4 3.0c 'northwood'), I could clock to 3.5 ghz using the ASUS "AI Overclocking".

With my new heatsink, yes, I can clock slightly higher (3.6 ghz) - but even when I'm not doing anything, it freezes up after some time - within MINUTES (The temperature still remains low, 116F).

Is my RAM (2X512MB Geil PC3200 CL 2.5-6-6-X, where X is some number which I forgot) limiting my overclocking? I mean those are REALLY bad timings, I know. Or is it becuase I'm using ASUS "AI Overclocking" ?

By the way, is there any way to NOT overclock my RAM when I overclock my CPU?

There's a good possibility you've hit the wall on the CPU. 600 MHz over its' spec rating is a good OC. You could play around with Vcore, Vdimm, and timings, but you may end up with a 0GHz CPU running at room temp (dead CPU). I'd be quite satisfied with that OC, but that's just me....

Really? Oh, I thought 600 mhz wasn't that great. Well thanks for the heads up.

There is some info here: http://www.cpudatabase.com/index.cfm?action=search

It's really luck of the draw on CPU's. Some go high and some don't. You seem to fall right near the average for a 3.0C.
