[quote=xago666;128528]Nah, it was no big deal i just finished stage 2. sorry 1 more question, what should i set the following to:

-# of worker threads
-priority
-cpu affinity
-# of CPUs to use

thanks guys[/quote]
2 (you have two cores, and want to run two separate numbers on them)
1 is fine (lowest priority, so it doesn't interfere with your work)
select "All worker threads" and choose "Smart assignment"
1 (each thread uses one core)

alright thanks for your help guys, i love how all my other programs run soooo slow now :big grin: :goodposting:

Hmm...your other programs shouldn't be running slow at all. However, if you have allocated a lot of RAM to Prime95, there won't be much left for other programs (hence the slowdown) during P-1 stage 2. However, rest assured, that only happens during P-1 stage 2.

Hmm, with such a machine I suggest to change O.S. GNU/linux user friendly distro like openSUSE, UBUNTU, LinuxMINT, install mprime 25.6 , run it, and if you like XP very much, you can install a virtual machine and run XP on it.It ś not a trivial task for an absolute noob, but it is good chance to try another O.S.

Yes, I agree--Linux generally has less overhead, so it doesn't steal as much power to keep itself running. Thus, it is highly recommended for any dedicated crunching machine, or for a non-dedicated machine that you'd just like to get the maximum performance out of. :smile:

I use Ubuntu (Linux) personally on my primary machine in a dual-boot configuration with XP, and I've found it to be extremely easy to use, very low overhead, not to mention that it's got some good-looking eye candy in the form of Compiz, which is included with Ubuntu 7.10 (and its visual effects are, IMO, even better than Vista's, and yet it uses hardly any resources to do it--it runs great on my relatively wimpy graphics, which Vista's Aero wouldn't even run on), if you're into that kinda stuff. :smile: Anyway, long story short, highly recommended.

"Adjacent Cache Line Prefetch = ON"
 

Set "Adjacent Cache Line Prefetch" or "ACL Prefetch" to ON, if you have it in your BIOS. (The factory setting was OFF.) This single BIOS setting made my dual-quad Xeon run 10% faster (if you run a lot of threads, of course). It's an obscure parameter; OFF is better if it was used as a server (i.e. a lot of different tasks); but in my case I got this as a workstation (and it runs some P95 in the background).
