Crossfire CPUZ

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.

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.

Have you tried each card individually, looks like one card is stuck on full speed and the other stays in power saving mode.

Yeah I did they work fine on thier own - any specific way to test?

kg648 · 11 May 2011 at 22:43

Yeah I do mate but it doesnt let me do anything within them, is that the same for you?

kg648 · 12 May 2011 at 09:57

Yeah, and its ticked.

run a 3dmark and post your scores

As above pal

2.67 I think it'll show 2.2 because speedstep is enabled.

there is your problem then you need to crank that cpu up to about 4GHZ

Seriously? when playing games none of the cores every go above 40%

Random thoughts, you installed the motherboard chipset driver? tried running the windows experience index?

Will do give index a shot now, Yeah I installed all the drivers from the Asus website.

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.

I did forget to mention something rather important I am running in eyefinity at 5760x1080

How do your scores match up to these?

http://www.bit-tech.net/hardware/graphics/2009/11/24/multi-gpu-round-up/3
http://www.xbitlabs.com/articles/video/display/radeon-hd5800-crossfirex_4.html#sect0

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.

Do you mean checking with fraps the fps? or have i missed something

GFX wise on 3dmark they dont seem far out I get 27718 and on thier chart they get 25399 so I seem to be way ahead of that.

Just added full system specs in the first post if it is any use, but to me my system is more than capeable of what I am asking of it... correct me if I am wrong?

If i disable crossfire altogether, it works flawlessly with the single card well odd spot of bother here and there but very rare. ( with eyefinity that is too )

So one 5870 runs 5760x1080 silky smooth?

Aye, apart from for example going to a new scene on Crysis2 it will have a split few seconds of lag.

Have you tried both 5870s in single mode?

tried that, works flawless with a single monitor in 1920x1080

kg648 · 12 May 2011 at 11:36

Think maybe i would just be better going with the single card solution getting something a bit beefier?
