Hi all,

1st post here but long time lurker.

Current system:
i5 2500k @ 3.3ghz - stock cooler
Asus P8P67 Pro
16gb kingston hyper x ram
Antec 550w modular PSU
Asus 6970 2gb
Win 7 pro x64

I just got the 6970 [upgraded from a HD 5770] and its in and running ok. I cranked up the settings to max on Deus Ex HR and it ran ok but looked like pretty low framerates and then the game crashed to black screen and recovered to low framerates.

I know that some of you will say buy a bigger psu but really this should be able to cope. There are settings in CCC to reduce power consumption by 20% aswell to help me rule that out.

I also removed the catalyst 11.8 and installed the 11.9 drivers - did this via the catalyst install manager.

CCC was reporting the card at proper specs 890 gpu and 1375 ram and sitting at about 50 degrees.

Im wondering about the drivers and if these remove properly, there used to be a tool on the ATI site to remove them but cant find it anymore. Anyone able to offer advice - if I have missed anything?

Cheers!

In your driver file, named either AMD or ATI ? (do they use AMD now?), im actually not sure and cant check as im not using drivers at the moment. Any way there will be an uninstall manager in there.
Run that and it should uninstall the drivers for you. Stick to default settings if it asks which drivers to uninstall as it may give the option to uninstall the chip set drivers as well so leave any selections offered as they are.

PSU: Antec TruePower TP-550

http://www.antec.com/pdf/manuals/TP-550_Manual_EN.pdf

12v1, 12v2, 12v3 and 12v4 all say 20a max

Connections are as follows: 12v4 rail goes to 8 pin [6+2] to the left most socket on the Gcard. 12v3 rail goes to two 6 pin sockets via molex which then turn into an 8 pin connector via an adapter which came with the card this plugs into the rightmost socket. Gonna pick up a 4 pin to 8 pin converter.

I have setup a second screen so I can watch CCC temp while testing again but I do not suspect this to be high - will post once tested.

Thanks for the responses so far.

Just had a little test of deus ex again. setting: 1080p no AA and lots of other low settings. GPU temp got to 68c but activity never went over 40% and fans only went to 21%, no crashes just awful framerates. This has got to be software i think...my 5770 ran this game much better!?

EDit: TF2, pretty good framerate but not great, temp 62, activity 22%, fan 14%.

Further edit: Back in Deus Ex, switched over to DX11 mode and highest settings - bang thats the ticket! got to 78c, 80% gpu activity. Very smooth. So new question - do these 69xx gpus have trouble with DX9? Seemed sluggish in TF2 and that runs in DX9 mode?

If you're getting 22% and 40% GPU usage, then there must be a bottleneck somewhere, but I doubt it's in the hardware.

GPU z shows 256 bit bus and everything else correct. Turned off vsync [doh] and get ~300 fps in TF2.

I think it just didnt understand why i was trying to play deus ex in dx9 mode, once in dx11 it runs great and this just happened to be the game i was tesing with. Pretty happy with the performance now.

Thanks for the responses. Picked up Civ 5 to have a little play with too.

The bus interface should read something like PCIe x16 2.0 @ PCIe x16 (or x8, x4 or x2 if things are not well seated).

But if performance is good, then all is well.
