post #15431 of 38701
Decided to test the 12.8 drivers... just out of sheer curiosity, since 12.7 had been working just fine. No issues yet, and it might be my skewed perception, but I think my GPU runs a tad cooler now and I have lost a couple FPS in various games, but the latter is difficult to quantify. Also added CAP2 where I did not use it before at all, and GW2 runs somewhat smoother.

Full-screen mode:

12.8 Release @ 1125MHz core / 1575MHz vram (stock voltage):


12.7 Beta @ 1125MHz core / 1575MHz vram (stock voltage):



More Heaven results with other clock settings - click to show (Click to show)
Windowed mode:
12.8 Release @ 1125MHz core / 1575MHz vram (stock voltage):



12.8 Release @ 1090MHz core / 1575MHz vram (stock voltage):
This is my fully stable stock overclock, although I suspect 1110MHz is okay too - still testing. 1125MHz on core works fine in Heaven but some of my games end up crashing the display driver eventually.



12.8 Release @ 1090MHz core / 1575MHz vram (stock voltage) with Lucid Virtu on (non MVP, the generic version for lowered temps and power consumption - helps a bit!)


Anyway, just figured I'd share. I did a full uninstall of the Catalyst software and display driver, restarted in safe mode, ran Driver Sweeper, restarted and installed the 12.8 drivers. I suspect some people have trouble with the new driver due to the lack of a clean install.

I dont know what is it with 12.8 drivers but its just stupid. When I use them I get alot of texture flickering in BF3 but once I go back to 12.7s or even 12.6s the flickering is gone. Does AMD get anything right. All I want is a solid driver set. I hear RC11 is the most stable so I may jump on them. Does anyone have any benches from RC11 vs 12.7?

Should try 12.4 before going to RC11.

RC11 is the fastest driver for cfx I've used yet. I think 12.6 or 12.7 is faster single gpu though.

Its the first AMD driver which was considered a stable and good performer. released in late Jan

If 12.7 beta is stable stick with that. Its the highest performing AMD driver as of date. RC11 is a good choice if you have major driver stability isssues.

Can you crossfire two separate non-reference 7950s?

For example, a His IceQ, and a Shapphire?

Maybe for single/dual cards but not more.

What if one has boost, and the other doesn't? Then what happens? Does boost auto-turn off, do both boost, or what?
