Poll: ATI cards clock speeds

[DVAFP]

had it limited to 507 mhz dont know why with catalyst 10.9, updated to catalyst 11.3 and its now correct. improved my fps too, thanks for bringing this issue to my attention, had those crappy drivers for a long time.

have a 4870 2x 1 Gb ddr5 by the way.

My 5870 clocks down to 400 mhz (from 850) for some reason. Is there an easy fix for this issue? I'm using the 11.4 beta driver.

Mine is still stuck at 500 MGHz clocks, which is a bit of a pig. I'm not sure if the dev team are addressing it.

Never had the problem, but am running MSI Afterburner (mainly for a modified fan profile, but have tweaked the core and memclocks too)

[Triggaaar]

Has anyone got a solution to increasing their minimum clock speed? I really need to fix it so I can spend some hours, rather than minutes, flying.

ATI Tray tools allows me to increase the minimum up to 880 if I increase the voltage to 1.175, but after the game finishes I don't know how to set it back to default, and ATT ends up crashing and being a general pain.

Thanks

According to AMD, the 11.4 beta driver was issued to address some specific issues with the 6-series cards. I'm using 11.3 with no such issues, although I am using MSI's Afterburner as stated previously. This is a mildly customised version of RivaTuner, and works with most modern cards if you want to give it a try:

S!

My 6970HD seems to go for full speeds, checked with AMD's nice little resource monitor.

When I load MSI afterburner you can change your maximum clock speeds etc, but there's no way to force the minimum.

Anyway, I seem to have ATI Tray Tools working at the moment.
Right click on icon in tray
select Hardware, Overclock Settings
Drag core speed to your standard max (880 for me)
Increase voltage with the drop down selection (1.175 for me)
Hit Apply
Play game
Go back into overclock settings
Hit 'Set Default Clocks' (instead of trying to set them back manually, which was causing me problems)

My clocks don't clock up for Cliffs of Dover, so I have to force clock settings using MSI Afterburner. The unusual pseudo-fullscreen mode used by the game seems to be causing problems for the drivers. This is not surprising as most DirectX games are played traditionally in a full-screen mode as it offers the best performance.
