My ATI 6950 woes.

If you go into the catalyst control center, then click on graphics and then information center do you get the same info as me which is:

Driver Packaging Version 8.79.6.2-101215a-110532E
Catalyst™ Version 10.11
Provider ATI Technologies Inc.
2D Driver Version 8.01.01.1094
2D Driver File Path /REGISTRY/MACHINE/SYSTEM/ControlSet001/Control/CLASS/{4D36E968-E325-11CE-BFC1-08002BE10318}/0001
Direct3D Version 8.14.10.0795
OpenGL Version 6.14.10.10315
Catalyst™ Control Center Version 2010.1215.2136.38682


Just wan't to make sure you are on the right driver package.

Certainly looks like it.


I'm using MSi to monitor, and also checking with GPU-z, both show the same core clock@500mhz.

If I restarted CCC the problem seems to fix itself.
I actually realised it when I noticed my framerates dropping off while I was playing, I'm framerate sensitive. :p

yeah, 5760x1200 is no fun with 500mhz core clock.
 
Have a look in catalyst control center in the overdrive section and see what the core clock is set to. If it is at 800 then try enebling Ati overdrive but leave it at 800 on the core and 1250 on the memory and see if that helps.

This is puzzling after a few steamboats:D

Edit: you may have to click the little padlock to use overdrive, also what happens if you use just one monitor, are your clock speeds ok then

I use one or both, makes no difference.

ATI overdrive is enabled by default, and I already clicked the lock and used that anyway, doesnt do much.
 
just found another thread on these forums with the same problem but he solved it

in post 11 he solved his problem

Gareth, cheers mate. Solved the problem. From another forum:
"Anything accessing the graphics cards UVD (Unified Video Decoder) mode will change the clocks to UVD clock speeds"
Stop playing music videos on YT... done.
Hello 825MHz

Also just found this on a review of the 6950

'The AMD Radeon 6900 series have three power profiles. At idle, the card runs 250MHz/150MHz core/memory clocks, at 0.9v vCore. For dual display, this increases to 450MHz/Full core/memory speeds. During media playback, the core clocks set to 500MHz, with full memory speed. Both these modes use 1.0v vCore. Under load, a full 1.175v vCore is applied, with full 3D clocks. During PowerTune the core clocks are reduced to 500MHz when a heavy load is detected.'

Well I just tested it, sure enough, youtube video open in the background and it downclocks to 500mhz, turn it off and its back to 800 again.
Thanks guys. :)


Bit of a pain, I'd often listen to youtube playlists while gaming.
 
Congratulations, you've discovered amds genius in creating drivers with powerplay which they decided that if you run content requiring high clock speed and content requiring medium clock speeds then the card, which has just increased its workload, should decrease its clock speeds (obviously). You have now joined the happy bunch of amd users (every single one of them) who've been complaining about this for more than a year.

Having to close everything make me feel like I'm using an old 7800gt again. If you have oodles of ram you can't leave anything gpu accelerated open really, and everything is going gpu accelerated. Heck there's actually games that trigger this. It's bad driver design, and has been for a very, very long time.

Better; ask yourself who (or why) anyone would create something that reduces the available resources when the load increases.
