Help with crossfire random stuttering - Page 6

post #51 of 68
Thread Starter 
1) Yep, individually each card is great. Not to mention I also get 970/1250 completely stable individually but I can only max at 900/1150 in crossfire mode.
2) Yes, I have tried a different bridge and in different fingers. Name any combination, I've tried it. I've noticed no changes.
3) The only things I have running in the background (aside from OS processes) are drivers and GPU monitoring programs.
4) I don't know. They're both non reference but as far as I can tell they only have different coolers. One is an HD-585X-ZAFC and the other a HD-585X-ZNFV
5) ULPS is disabled.
6) Nope, I haven't, and I don't really plan to. I've been trying hard to keep a clean install so that I don't have to reinstall the OS on my SSD.
7) How?
8) Vantage gives me 31k GPU and 24k CPU. Seems normal to me.
9) I think I'll try 10.5a today.

EDIT: Just checked, both PCIe lanes are running at 2.0 x16 and both cards have the same BIOS.

Oh, forgot to mention that Crysis benchmark at 5670x1080 Low yields the same stuttering as 5670x1080 Very High

Have you tried reinstalling the drivers? It seems to me that you've got two issues going, the strange cfx behavior compounded by a vram, or you will see it once you fix the cfx issue.

The problem was the scaling in the 5xxx series cards. I have the same problem with all games while running X-Fire and Tri-Fire with 5870's and 5970's. I got 6 FPS while running Tri-Fire in multiple configurations and around 20 with a single 5870 enabled. For what ever reason the 5xxx cards do not scale well,actually negatively, especially in games designed for nVidia, like Crysis and Metro.

I was never able to find a solution for the issue. I ended up selling all 4 of my ATI cards and jumping ship to nVidia. I have not had any of the same problems since than.

However, I have heard newer driver releases have helped with the micro stutter and lag issues that you are experiencing, which is identical to what was happening to me.

Sorry moltar but you are just plain wrong the 5*** series scalling is actually excellent https://spreadsheets.google.com/ccc?...COyTgbgP#gid=0 Those are the results of some tests i ran after I got my second 5850 recently. Obviously you were doing something wrong or the drivers have drastically improved since you had your cards.

I guess, let me rephrase my original post. The scaling is terrible with Eyefinity on. There is a serious problem with Crossfire and Trifire when Eyefinity is being utilized. Your benchmarks might be all well and good but try it with 3 monitors and see what happens.

That technically is a vram issue not scaling.

Its not Vram because the OP has tried playing at lower resolutions like 640x480 and the problem is still apparent. The issue is related to Eyefinity. Read the entire thread and you will see that the OP has tried several things to append the situation.

It's math dude, run eyefinity and there's more pixels than there is vram. He's got two issues going on.

Its not math. Its problem with the 5xxx cards. Ive been running 3 displays while gaming for a few years. I've done more methods than most people know exist on this site. Do you want to explain to me how you get 6 FPS with 3 5870's in TriFire on Crysis? Or, why you get 4 FPS with 2 5970's in QuadFire? Thats 3GB/4GB's of Vram respectively. I don't think Vram is the problem.
