Hi,

ive got a 3.4ghz cpu but ive just installed cpu-z and it says that my processor is running at around 2.8ghz but the actual speed it gives fluctuates alongwith the voltage? What has happened, i have had a look aorund ym bios but havnt chnaged anything that i now of. Is there nay way i can just restore bios to the default speeed of my cpu?

Thanks for any help, Dan

take a screenshot, that will give us a little more info

also, you can restore the default bios settings. look for the option it will be there towards the end of the choices.

Speedstep is taking over, do this, Open cpuz, then open super pi and run a 1 meg test, watch your cpu jump back up to the stock speed, If your mobo bios has a C1e or thermal controll disable it and u will be fine.

or go download RMclock and use that to disable thermal controll...

This is indeed EIST, it has the ability to reduce the system multiplier to x14 on a compatable CPU/motherboard. This also allows the voltage output to the CPU to be reduced giving a decrease in temperature. This can be disabled either in the BIOS or in Windows but I would not disable it if I were you unless you really want to.
After about 50% usage the CPU will revert back to its standard multiplier and the clock speeds will return to normal

HI, ive found that option for speedstep in my bios but it was already disabled? Are there any other reaosns for my cpu under clocking?

Here is my cpu-z screenshot Attachment 18313

Are you certain it is disabled?

The multiplier on your system is reduced from its default x17 down to x14. Also the voltage has been reduced which would show SpeedStep effects.

The only other thing I could think of is if you had forced the motherboard to only run a x14 multiplier.

I just checked again and it says that speedstep is diabled.

I couldnt find anything called cool n quiet but someihtng called cpu thermal internal something was an auto. Would this be doing anything?

The strange thing is that when i open Everest home edition it syas that my cpu is running at 3.4 could cpu-z be the problem?

here is screenshot of both programs Attachment 18314

i had this problem also on my win2k, my cpu was a 450MHz and it read 299MHz (or something like that anyway), on lotsa programs including cpu-z
i know this might sound a bit stupid but i decided to install winxp instead and also, swap my ram sticks around i.e. take the one which was originally in bank0 and put it into bank1, and vice versa for the one which was originally in bank1.

the problem was solved, not exactly sure which of the 2 procedure above did it though,
(oh well, worth a try)

hmmmm well i can resort to this if nothing else works! This is really annoying my BIg Typhoon has just arrived and i was going to start to overclock and already im underclokcing!!! Ive tried restoring bios to default but silll cpu-z is saying it is 2.8 BUT when i load up cpu-z it says 3.41ghz (fluctuates) for a few second and then drops to 2.8ish Any ideas? Cheers

Please read the first page of the thread. The guys already nailed your issue for you.

They havnt nailed the issue becuase i have tried everything they have said and it still is at 2.8
But thanks for all the help i didnt mean to soundy *****y there

I found someting in my mobo manual called 'CPU Lock Free' It says that this changes the cpu multiplier to 14x which seems to be what is happening to me. In my manual it says that this option should be under 'JumperFree configuration' but there is only AI overclocking there. Is there any way that this option has been hidden or anything?

Did you check to see if it runs properly above 50% load? Did you try disabling EIST?

Lock Free enables you to manually drop the multiplier to 14x. That allows you to utilize extra RAM bandwidth if you have good enough RAM. It's a nice feature if you have the hardware to support it.

EIST is disabled and ive loaded the default bios and checked that eist is still disabled.

The lock free thing was the only reason that i could think of why my multiplier is at 14. If i open up a number of programs at the same time then cpu-z flashes up at about 3.41ghz but then straight back down to 2.8.

I oc'd my cpu quickly at 5% to see what woud happen. And the oc registred in everest and in cpu-z but cpu-z still siad that the multiplier was 14 and everest sadi 17. IS cpu-z the problem?

Thanks for all the help guys

It is possible that CPU-Z is the culprit. Try running a couple other applicaitons such as Asus Probe and Sandra to see if they agree with Everest or CPU-Z. Also check Control Panel/System to see what it says about your clock speed.

I'm not familiar with your RAM off hand, but if it can take some overclocking, go ahead and drop your multiplier to 14x. Up your clock speed to get back to the stock 3.4 GHz. The CPU won't much notice the difference between 200x17 and 243x14, but the extra bandwidth on the RAM will definitely help performance.

Whats super pi some program? Ive downloaded sandra and it says that my cpu is at 17 not 14 so im goign to assume that cpu-z is just being a bit dodgy Attachment 18316

But id like to know what this super pi thing is so that i can make sure, COuld you give me some information on it please. Thanks, Dan

Check out our downloads forum. There's lots of SuperPi info there including the program itself for download.
