Sorry for ask, isnt mine too low for a Athlon XP barton 2800 +? I f it is, what can I do to improve it?

P4 560 LGA775
 

Results for P4 560 LGA775 cpu overclocked to 3.5GHz (using dual channel DDR2 533MHz memory). CPU is the Prescott D0 stepping. Operating system used is Linux Fedora Core 3 on the v2.6.9 SMP kernel.

The cpu is totally stable, and I can even overclock to 3.6+GHz. But when running Prime95, the temperature soon nears 80 degrees.... something I'm not too comfortable with. Once over the 3.5GHz mark, temperature increases exponentially. I've capped the overclock to 3.5GHz - temp is just a tad under 70 degrees using stock cooling.

Go download the new 24.6 version of Prime95 (you are using v23.8). It should give you almost a 20% speed up! :)

Oh, thank you, I will try that

Wherer do I find it? It isnt in theDownload section...

Whoa, there's a new version? That helps Athlons?!!! I stopped checking like a year ago.

It is a beta. "No yet ready for prime time" so to speak. A few problems have been found. At least 1 fixed. Another is being checked on. A tweak is need to keep it from slowing down the P-III's. And we need to turn in a few DC's to check on it.

For the fun of it I ran benches on the same machine with v22.1 (what I started with on this machine) in my normal config and v24.6 in safe mode.
