I'm new to all of this, but I like the option to 'show off' my hardware (even when there's no refrigirator-cooling on the CPU :)) - this seems to be the place to do it.

Having computers at my disposal, I like the idea that they can do something useful in their spare time... :)

Seems likely to be a lotta $$$ for a just-under 25% overclock....

The case cost me $450 us

Motherboard + Memory + CPU costed $500 us

$450 for a case. *yeep*

I thought my Shuttle SS51G was expen$ive - but it was case/ps/motherboard/heatpipe HS combo, for around $320 (they've gone DOWN since then).

I bet it could be one heck of a gaming machine, though.

That´s over 30% OC... great! How do you cool it?

Just stock intel cooler. However its at some rather high temp. About 60'c full loaded. I am going to get a better cooler. I havent even add more voltage to the CPU. Its still running at 1.525v stock.

My Athlon XP 2700+ running at stock speed. Anyone have any suggestions into increasing the speed, without overclocking?

You could try getting more aggresive with your memory settings - my XP1800+/KT7A went from about .252 to .237 (10,000,000 digit exponents, 1792K FFT) per iteration just by switching from "sdram 8/10" (AKA slow default) and CAS 3 to "normal" and CAS 2. I tried the "fast" and "turbo" memory settings, but they made the machine very unstable - though they also got the iteration timings down to around .222 at fastest settings.

Best bet would be to push the FSB and memory settings as high as you can get them to go, *dropping* the CPU clock multiplier if you have to, while keeping a close eye on the stability of the machine.

Prime is VERY memory-intensive - one of the reasons P4s beat Athlons on it (SSE2 is a bigger reason, from what I've seen).
