Poor eyefinity performance, crossfire 6970s

You mean you have bfbc2 running at eyefinity res and get decent fps ( like more than 40 ) on all high setting with AA ?

Yup, aa is set to 2x ingame which i think equates to 4x, just had a run around a 32 player atacama server, fps generally around 60+ spiking upto 90+ on occasion.

Was there not any problems at you ran into when you set up crossfire and eyefinity ? Did you have to change any bios setting or anything like that, anything at all ?

Might be his board!

I think guys you are all getting the same kind of problems and he isn't. Do you guys run driver cleaner? I would stick to 11.2 myself too as those are official drivers.

kevy1986 · 12 Mar 2011 at 16:48

I well I ran a complete fresh install of win 7, and put on 11.2 with profiles and same results.

i too bought 2 6950's and 3 28" 1900x1200 screens to do eyefinity on. once i get my new rev board i will set up all three monitors and see the results

what system are you guys running? some people reported lack of performance with old Q6600 systems...

kevy1986 · 12 Mar 2011 at 17:38

i'm running old q6600 system however the other people in this post are running i7s SB and having the same problems. Just out of interest BaDBoY_uK & Shayper have you guys tried flashing your cards to the full 6970 bios ? I'm running both my cords on a modded 6950 bios with changed voltage and open shaders. I wonder if flashing both cards to full 6970 will make a difference. Well i'm going to my girlfirends tonight but may try this tomorrow. I have tried messing with the crossfire bridges to see it it makes a difference but to no avail. Please let my know if you guys have any progress.

Mine is in my sig!

Try the eyefinity with 1 card check the fps.
If the cards are different models check the clock speeds and even them out or overclock them to match up.
Quick switcharoo of the cards on the mobo

Sometimes its something so small that creates huge problems with computers

im sure il be in your shoes on the 25th of this month as il be making the plunge.

BaDBoY_uK · 12 Mar 2011 at 23:06

Not worked at all mate
Have open query on AMD/ATI forums... we'll see

BaDBoY_uK · 13 Mar 2011 at 09:11

Just figured out that my issue comes from the GPUs not being totally utilised during gaming. Each hits 50%ish and results in 50FPS with medium settings

I uninstalled latest 11.2. Installed 10.8 and then put ONLY the 11.4 driver over the top

The next step is to make both GPUs hit 99%

kevy1986 · 13 Mar 2011 at 11:10

Hey mate, I notice when I had msi afterburner running that the gpus weren't hitting 100 percent aswell. They were hovering about 50 - 70 most the time. not sure if that was right or not. How have you got on with the 11.2 and 10.8s together ? I would really like to get this sorted. Glad to know i'm not alone with this nightmare

Any suggestions you have i'm happy to try, got most of the day off to work on this.

How are you uninstaling the drivers? Are you using the uninstaller that comes bundled with the dirvers or are you doing a clean uninstall with driver sweeper?

I think if it hit 99%, we'd achieve better FPS rates. 10.8 CCC with 11.4 drivers seem to be ok

Tried RadeonPro and Xtension 1.4. Both do not work and 50% GPU usage remains. I need to figure this out

Full uninstall mate; uninstall + driversweeper and ccclean in safe mode. I have been here before

Kev Im pretty sure its your q6600. Have you checked the link in your thread?

kevy1986 · 13 Mar 2011 at 11:29

I'm playing with the registry right now muggs, I'm planning on running a heaven run shortly and comparing with yours. Not really had time to check you post but will take a look in a bit. I really hope it isn't the Q6600 as won't be upgrading until Bulldozer is release. I see where your coming from tho. It is old tech but it still holds it's ground with everything else.

Shayper · 13 Mar 2011 at 11:43

Yeah badboy I'll try that as soon as I get back, what you are reporting is exactly the same as me, even under crysis warhead at max settings I get 60% usage on each card, cheers a lot

Now just gotta find out if this works lol
