Good evening,

Ok well another one of my moaning threads about a similar issue but here goes;

I have just been looking at my machine in CPUZ in crossfire is it normal for one card to have a different memory/core also for some reason does not show the pci-e version it is running at, just a tad concerned it is running at a lower spec than it should be or my mobo is bottlenecking it.

I have a Asus p6t deluxe with 2x 5870 in the pci-e 16x slots
card #1 shows 849mhz core 1200Mhz memory
card #2 shows 156mhz core 418Mhz memory

I just feel something is not right with my setup every game I get is giving me crap results reguardless of what driver I use, I know xfire is rather buggy but all the games I have played the only one that works properly is Batman AA.

I know Crysis2 is buggy but I get unplayable fps with it unless i change it to high performance even so it is better with one card.

Blackops isn't exactly as 100% as it should be still slightly laggy here and there. it just feels as though my system is struggling.

Do I need to change my motherboard?

Also sometimes at boot my cards/card goes at full fan speed, I then have to turn the machine off for 5mins or so and then it works fine again - I have tried the swapping the cards around but always seems to be the top one which the fan speeds at full on, when this happens I get no video output.

Specs are as follows;

Asus p6t
i7 920 d0
12gb DDR3 Tripple Channel
2x 5870 in eyefinity with 3x 22" @5760x1080 60hz
850w PSU


Thanks in advance.

The cards connected using a crossfire bridge?

can you run a demo such as 3D mark or http://unigine.com/download/

does things change then?

Im not familiar with the catalyst control center, is there any crossfire settings to fiddle with?

Have you tried each card individually, looks like one card is stuck on full speed and the other stays in power saving mode.
 
Can't see any specific xfire settings there is a settings tab but no settings for it which is odd.

I ran it the other day - http://3dmark.com/3dmv/3138305

Yes they are connected via a single xfire bridge :)

just noticed power settings were set to "balanced" should this matter? just changed it to high performance now, maybe i need to fiddle with some more bios settings or I am being silly.

I have made a fresh install of windows with the latest drivers with caps profiles, same thing happened on older ones.

you got this? see the performance section?
 
Im running Nvidia SLI, so its all guess work for my help.

re-install to the latest driver? i think its 11.5 now.

or boot to safe mode, run driver cleaner, reboot to normal mode, then install the driver?
 
Have you got this option at all in Catalyst?

If not might be worthwhile checking your bridge again.

Ignore the horrid white bit, my resizing failed soz.
 
Random thoughts, you installed the motherboard chipset driver? tried running the windows experience index?
 
one card is meant to power down when not in 3d mode

like i said the only reason your scores are low is that your cpu needs overclocking.
 
How do your scores match up to these?

Both use i7 systems from,

Mainboard:ASUS P6T Deluxe (Intel X58 Express), LGA 1366, BIOS 1701;
CPU: Intel Core i7-920, 2.67 GHz, 1.25 V, L2 4 x 256 KB, L3 8 MB (Bloomfield, C0);


Intel Core i7-965 processor (3.2GHz: 133MHz x 24)
Asus P6T V2 motherboard (Intel X58 Express with three PCI-Express 2.0 x16 slots)

So i dont think 4GHZ is going to solve your issues.

The experience index score is meaningless, instead when its run, the system seams to learn all the connected hardware, if its never been run before? then it can help
