Because your special.

i reran it again and got a 65.5 ~ maybe its this canterwood moboard

Well I did a bit playing around with my memory and my system clocks and wow!
I guess this little proggy is very memory reliant too...
I went from 3.45ghz memory 384mhz 2/5/3/2 with a score of 65.xx(first post)
to cpu now at 3.33ghz memory 462mhz 2/5/3/2 score of ........

actually~
i think this benchmark likes memory write speeds inperticular.

if you run the same comparison using aida32 membench ~ i think youll find your write speed incresed alot when using the ratio. (thats why your SCDDR does so well on this benchy)

or at least it would be interesting to find out

GenTarkin · May 2, 2003

WOOT! =)

I wonder if this memory can go any higher....hrm....

an odd thing bout this board (4PEA+) is it will not and does not like running memory at relaxed timings =? lol I tried 2.5/7/3/3 and crash crash at the speed I am at now with 462mhz 2/5/3/2
odd...

New Score with higher fsb.
Check siganture.

That eval copy of WinRAR is teh suk. It closed my command prompt before I could even write down all the numbers or take a screen shot.
But the total time was 67.23 sec. 0.02 hours.

Albatron PX845PEV Pro, 256MB XMS PC3000 (2-3-2-7) @ 425DDR, 2.53 P4 @ 3.23GHz.
Gunna try boosting my mem voltage to 2.8 and see if I can get it to turbo settings to see if that helps out in time.

SinfulWeeper · May 2, 2003

Turbo was a no go.
Even @ 2.8 volts, 2-2-2-5 was a no go 425ddr.

I lost a little of time on that run. I think I need to learn to tweak WinXP a little. While it boots faster than my instalations of Win9x, it seems to be very heavy in the CPU/Memory dept.

It didn't get much better with the new CPU

infinite012 · May 2, 2003

It doesn't run properly on my computer =O Does this mean I'm running the CPU too fast?

Have you run Memtest86, Prime95, or other stability tests? If not, do...

infinite012 · May 2, 2003

Is prime95 for an hour or two good enough? Because I've done this and the computer seemed to be fine...........And I'm sure that my RAM isn't bad...

I also ran 3dmark2001se 2 or 3 times to check my overclock was good or not and luckily enough the computer never crashed.
