Radeon HD 5770 crossfire problem ...

Hi Guys..

I'm running a sapphire Crossfire ATI Radeon HD 5770

Gigabyte GA-890GPA-UD3H
Phenom ii X4 3.2Ghz (overclocked to 3.5 with stock voltages)


In CPU Z I'm getting two different readings though

1st Radeon HD 5770 is giving me :

core: 399Mhz
Memory: 900Mhz

and 2nd Radeon HD 5770 is:

Core: 859 Mhz
Memory : 1200 mhz



Question..
Why?

Aren't they supposed to be equal?
Any help will be greatly appreciated. Thanks


NB: (I disabled AMD overdrive because the values were lower for the 1st video card)

Is there a chance that this is an error?

Best solution

maybe the first card is clocked down in 2d...run a game with GPUZ in the background and log to file...then exit out of the game and see if they are running the same speed....is crossfire enabled?
