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

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! :)

Arthanis · 2004-12-14, 08:51

Oh, thank you, I will try that

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.

First the old V22.1

Code:

Best time for 1536K FFT length: 335.572 ms.
Best time for 1792K FFT length: 402.351 ms.

Now the new V24.6 in safe mode

Code:

Prime95 version 24.6, RdtscTiming=1
Best time for 512K FFT length: 58.654 ms.
Best time for 640K FFT length: 81.064 ms.
Best time for 768K FFT length: 99.040 ms.
Best time for 896K FFT length: 121.605 ms.

Best time for 1792K FFT length: 254.494 ms.
Best time for 2048K FFT length: 282.304 ms.

Comparison

Code:
