Low Superpi score

Brian Stuart · 17 Nov 2008 at 13:39

My PC is as in my sig but when I run superpi it gives me a score of 34 secs for 1m calcs.
I've looked at the superpi thread in the overclocking forum and my score seems very slow indeed.
It is a relatively fresh install of Vista HP 64 bit with very little running in the background.
Any help or advice welcome.

Seems low for your spec, what timings are you running your ram at?

Brian Stuart · 17 Nov 2008 at 16:41

5-5-5-18 Also disabled AV, firewall etc when running superpi.

That is very slow for that CPU, especially as it's overclocked.

Tried in safe mode just to make sure nothing's interfering with it?

Brian Stuart · 17 Nov 2008 at 17:17

will do
15 secs in safe mode :confused:

I've ran antispyware and AV (Avira) and everything appears OK.

All power saving options off and Speedstep etc disabled in Bios?

Craig321 · 17 Nov 2008 at 17:34

At least it's not a hardware problem then

Check in the task manager, make sure nothing's maxing out the CPU/using crazy amounts of RAM.

Brian Stuart · 17 Nov 2008 at 17:42

All of the power savings are off. Seems to be nothing untoward in task manage,r CPU usage varies between 0% to 15% and RAM usage in normal. I'm baffled, the PC seems snappy enough and the games I play, Crysis Warhead, FO2 etc run great.

Strange.

What about hard drive activity, maybe superfetch/search/system restore/defender is doing something in the background?

Brian Stuart · 18 Nov 2008 at 09:13

System restore off
Defender off
Drive has finished indexing.

Craig321 · 18 Nov 2008 at 09:55

Very strange. Have you run 3DMark06/Vantage etc. - are the scores alright in that?

Brian Stuart · 18 Nov 2008 at 12:52

I'll do that when I have bit more time. Thanks for your help so far

Brian Stuart · 18 Nov 2008 at 14:17

3dMark 06 6713
Changed Nvidia drivers from 180.42 betas to 178.13 WHQL and got 5066
This was at stock in case the overclock was causing problems.
With the PC at stock my Superpi score is now 50 secs. I'm beginning to get frustrated now.

I would have thought it would bump the speed up when running SuperPi, but is Speedstep /C1E disabled, at least to test?

EDIT - looks like you might have checked this already?

Brian Stuart · 18 Nov 2008 at 16:11

I seem to have checked every damm thing

Have you cleared out any old chipset drivers or checked to make sure you have the most current chipset drivers for your mobo installed?

Mattus · 18 Nov 2008 at 17:35

Can you look at task manager whilst SuperPi is running to make sure it's actually using 50% of your CPU?

Brian Stuart · 18 Nov 2008 at 18:37

Chipset drivers installed OK It is using 50% CPU

Brian Stuart · 18 Nov 2008 at 19:20

Looking in the resource and performance monitor screen in Vista I noticed that the CPU maximum frequency is set for 50% I have no idea if this is correct or not so any comments welcome.
Found the problem

Power management was set to power saver which limited the CPU to 50% maximum frequency. Set power option to performance and now my SuperPi score is 16 secs
Thanks to everyone for their help.
