I have an E7200 fitted to a Gigabyte P35 DS3L wit the latest bios, but the computer is showing 2 different speeds for the cores, one is 2.53 the other 2.4 any idea why it would do this or have I got a slightly duff chip?

It can't be thermal throttling as the temps never go above 40c on idle. Or is it possibly something to do with the board?
 
What are you using to measure the speed, looks one prgramme is looking at the multiplier as x9 the other @ 9.5 which is correct.

Use CPU-Z and see what that mentions.

According to CPU-Z the multiplier is at x6 :confused:

EDIT: Just looked in the motherboard settings at boot and it's set to 9.5 so no idea why cpu-z says 6

Right, it fluctuates between 6 and 9.5, I assume 6 is the lowest it is set to go and 9.5 is the max then?

Click to expand...

when its at 6 the speedstep function is kicking in, it does it when idle to use less energy. When on load it will revert to the proper multi. Check my above post for how to switch it off...
 
Would that account for this though?

Windows displays "Processor model @ stock speed" followed by the actual current speed. Normally its correct

My overclocked system for example says E6700 @ 2.66Ghz 2.8Ghz. That doesnt mean the cores are running at different speeds, just "stock" and "actual".

I cant see any reason why your system would be running at 2.4Ghz, unless the motherboard is not supporting .5 multipliers and forcing the chip to run at 9 instead of 9.5. Try a bios update perhaps?. I guess windows could be getting it wrong, what do other applications say (TAT for example, or CPU-Z). If TAT/CPU-Z show the 6 multi from speed step, just run a mildly processor hungry application at the same time. That will flip the processor to full speed.

If TAT/CPU-Z show 9.5 Multi, and 266 (or 1066) fsb, then I can only imagine windows is getting it wrong.

Just saw above that your getting the 6 and 9.5 multis in CPU-Z. Thats good, so the only other possibility (assuming windows isnt simply wrong) is your FSB speed is underclocked. It would take a FSB of 250mhz (1000FSB) approx to underclock your chip to 2.4Ghz. It should be 266/1066. Again, if CPU-Z shows 266/1066 and 9.5 then the chip is running at full speed and windows is just wrong.

Just double checked the bios screen, the multiplier is set at 9 and the option below to fine tune is set at 0.5 this is screenshot of cpu-z with the cpu at load
