Why does wprime say this?

Wprime is telling me that my cpu clock is 1.5. I just reinstalled vista yesterday due to a major driver screw up, and now im getting 1 second slower testing speed, and its saying 1.5 cpu clock, last time it used to say 2527.5

whats the deal?

 

What does cpu-z says about you clock?

 

wPrime has that bug, it says the lower speed for many many users(if not all).
It tells me that i have 1GHz but the test was run at 2.33Ghz and the performance was correct. 31secs seems correct for you, so you shouldn't worry. Just a bug.

 

I think Intel speed stepping may be the cause for this.

Run wPrime in safe mode and see what happens.

(There was something like that on my SZ...)

 

I had a similar issue, wPrime captures the speed the CPU was clocked at when wPrime first starts and because of Speedstep it most likely captured a lower multiplier. It doesn't do anything to your performance but it did worry me the first time I saw it.

If you want it to display the full Mhz you can use RMClock to lock your CPU to the highest multiplier before you run wPrime.

Update: Just ran wPrime and it also claims my P8400 CPU is running at 1596 Mhz. This is strange because I don't have a multiplier for 1.5, I only have for 0.8, 1.7 etc. Maybe it is something else that is causing that reading but either way performance is unaffected. 32M wPrime score of 34 secs.

 

wprime is a real life benchmark, so it reads actual cpu speed at the point of launch.
It is very accurate, much better than passmark.

Only problem is that wPrime doesn't utilize dual or quad cores efficiently...

 

I think its good for dual and quads. It has issues with dual cpu systems like mine.

What do you read?

 

I know wprime errors on my quad socket 940 board. It wont even run.
It runs on my asus workstation dual socket board, but sometimes I question my 8 second Wprime. I would think it should be faster than that.

Ups - silly, silly, silly me - I confused wPrime with SuperPi - sorry.

 

Thanks for all the info fellas.

It makes sense that it it does what it does. Its a pretty confusing bug though. I ran cpu-z and in the clock section it fluctuates depending on whats going on.

Just wanted to make sure everything was normal. I'm just happy i got my laptop back to normal.
