Crossfire not using any load

[jimsparrow88]

Recently built my first ever pc, all appears to have gone well,

i5 2500k @ 4.4GHz
asus p8p67 deluxe
x2 hd 6950
8 gb ram

I have noticed that I get a slightly low score on 3d mark for graphics (cpu bumps it up though) but I run crysis 2 with dx11 patch ultra at around 40 fps, but others get 60-70 on the same setup.

Checked my gpu's on gpu-z and they are getting temps of 55-70c but only the first card gets any activity(load) and even then its minimal, eg for crysis 2 I was getting 30 fps at one point so I checked gpu-z and only one card went above 30% and stopped there, does that mean Im only using (roughly) 1/6 of my gpu power?

Crossfire bridge connected?

Have you enabled Crossfire in the CCC?

Have you downloaded the latest drivers and CAP's?

Do I need to ask about your PSU and that all the power connectors are connected to the GPU's?

Download Radeon Pro. You'll be able to see the actual usage of the GPU's while you play a game.

Yes.

Yes.

Yes. 11.8 for both

Psu hx 750w.

All the programs see the gpu's so connections are not a problem,

already got radeon pro but where does it let me monitor gpus?

Settings > CrossfireX > Tick the box to Enable the CrossfireX bar

Well the red bar at the side was equal for both cards so I guess that solves it, still abit annoyed about my 3dmark score and fps in game

I'm having a similar problem with crossfire 5850s. According to gpu-z, one of my graphics cards is at 100% load (during unigine engine benchmark) and the other is 0% or occasionally up to around 5%. I have the crossfire logo in the top right hand corner and when I use Radeon Pro the red bars go up for both cards up to around 80% at times.
Also gpu-z, radeon pro and unigine engine all show different FPS although unigine is the most consistent.
