ATI 6870 not overclocking (Low FPS)

S!

Noticed same on my 6970HD. Core clocks do not go to full, but to 500MHz instead of 880MHz. Memory clocks go to 1375MHz as should. Also noted better image quality with AF overridden with CCC, some artifacts went away with this. I use latest 11.3 WHQL drivers.

I don't have a maximum clocks, and I'm not sure how to tell if its stepping up or down.
I have a pair of 4850's in crossfire, but they are not both working in this game, the splash logo comes on in other games but not this one.

I did go into CCC and allowed the auto tune to OC it.

If you can explain I'll check what you ask.

S!

I left CCC open and alt/tab to check clocks during game. They did not go higher than 500MHz. I overclocked the card but still the same?!

Also these black cursors people talk about are gone for me. I closed all the info windows, could that do it? Also overriding AF in CCC helped with graphical artifacts.

I tested Very High settings and got 11-38FPS over sea/land. Lowering to High helped a bit, but there is a lot of pauses and stutter. When these issues are solved the game will look simply gorgeous

I have a second monitor and have the CCC open when in game for monitoring.

The setting for force maximum clocks is only in the ati tray bar. right click, select your top card (either one will work) than 3D settings and than force maximum clocks/enable

If that does not force one of your cards to ramp up to 3D speed than you will need to disable one of your cards.
