CPU-Z reporting different multiplier

[Kiteman]

Hi All,

I recently upgraded the BIOS of my EX58-Extreme from F4 to F12 after successfully oc'ing it to 3.82GHz. After the upgrade I reloaded the optimized settings, rebooted and changed to following parameters:
Turbo off, set to Standard
Turbo Boost: disabled
All power management features such as C1S and EIST were disabled as well.

Essentially, whatever the BIOS reported is what I was expecting to see in CPU-Z but I didn't. CPU-Z reports a multiplier of 10 instead of 20. It does, however, correctly report the base clock. Any ideas why that is? I even ran a stress test program (OCCT) to see if it would have an impact because I wanted to make sure that all PM features were in fact off. But the multiplier did not change. It never showed 20. Is it a bug with CPU-Z? I tried an older as well as the newest version but it did not make a difference.

Thanks for your feedback in advance!

Re: CPU-Z reporting different multiplier

Try to manually set your multiplicator to 20 and/or fill out the BIOS template, links is in Lsdmeasap signature.

Re: CPU-Z reporting different multiplier

im using f12 bios although my board is different a ud5 i cantsee there being much difference in bios or cpu-z versions,i have no problems with cpu-z and my multiplier being detected






^^^ try with that version of cpu-z

Re: CPU-Z reporting different multiplier

Did you get this sorted?

If not, I would say flash again, or reload optimized and try it over as I have not seen any reports of issues with F12.

And of course, be sure you are using the latest CPU-z

Re: CPU-Z reporting different multiplier

Multiplier is set to 20. I tried both F9 and F12, same result. And I used the latest version of CPU-Z. See what it's reporting:

Re: CPU-Z reporting different multiplier

Hmm, that is odd if you are sure you have speedstep disabled. No way it is a BIOS bug, they would not allow it to carry over from 9 to 12, 12 a bug maybe since it is new but 9 should not bug at all like that. How about 11, I know it is fine because I am using it.

Can you post a screenshot of CPU-Tweaker

Re: CPU-Z reporting different multiplier

Ok, reflashed with F11 and left all timings alone, meaning 20x multiplier, 133MHz clock, turbo on, etc. CPU-Z now reports this:




This wouldn't suprise me as the processor is throttled down as there is no load. Now I would expect the frequency to go up when I add load. But when I fire up OCCT the frequency stays the same! That doesn't make sense.

Next I will disable all power mgmt features and try again....

Re: CPU-Z reporting different multiplier

multi at x20, base @ 133, turbo off, and now this:



Interestingly the BIOS correctly reports 20x133 = 2.66GHz at boot. But ZPU-Z thinks differently.... Now what?

Re: CPU-Z reporting different multiplier

download everest and click computer/overclock and see what that says,it should show you full speed if c1e and eist are disabled...ohhh and btw you have windows 7???? if so make sure youve selected full performance in power saving options,balanced will do same as c1e ,and power saver will throttle cpu as much as possible

Re: CPU-Z reporting different multiplier

warren300, I was running Vista but now have installed Windows 7. BUT: it did not occur to me that Windows power management could be the culprit. And in fact it is: I had it set to "Balanced". After changing it to "Performance" the multiplier in CPU-Z showed what I had set in the BIOS.

Thank you very much for solving the "mystery".

Re: CPU-Z reporting different multiplier

yeah i remembered at the last minute,i have it setup the same,i disabled c1e and eist in the bios and selected balanced in windows 7...it will throttle your cpu only when idle just like c1e does but for me i get rid of the slight motherboard squeal with that setup

Cool, nice to see you found the problem! Had me thinking so hard smoke was starting to pour out :)

Just wanted to again say thanks and show you my initial oc attempt; welcome to the 4GHz club... wooot:

Welcome aboard!

Now, onto the stability testing you go!
