680 sli different clocks

[Skynet5]

When I run heaven GPU 1 runs as 1177 and GPU 2 runs as 1202.

Utilisation hits 89 on GPU1 and 98 on GPU2. Volts are the same, 1.175v

Any ideas?

Temp isnt hitting 70 on either card, as I have an agressive fan profile.

I thought boost varied on different cards, might be something to do with that?

I would say it is down to the Dynamic OC.

I'm sure there was a thread on this the other day suggesting that this is a normal Mhz difference between any two given boosting chips & the 1202Mhz card could be downclocked to 1176Mhz or whatever so they at least appeared the same.

Something like that anyway, you're not going to noticea 25Mhz on screen either way.....
