MSI 5770 Crossfire Issues... Poor performance pls help

post #1 of 30
Thread Starter 
Okay long story short

Orginal setup is:

Regor 240, Stock 2.8ghz speed

Paired with an MSI 5770 card.

I was getting benchmarks around 50-65 FPS in 1900x1080 modes. (Res Evil)

I ordered a second identical card to CF and installed it.

FPS on ALL benchmarks test dropped anywhere from 25-40 FPS consistently. (Res Evil, Dirt 2, etc etc)

I confirmed the cards were functioning correctly, in CF mode. Updated/Downgraded drivers, double-triple checked BIOS settings and confirmed both cards were both working and CF was enabled.

If I disable crossfire mode, the FPS jump back up to what they were before.

I do notice that the CPU is running at 100 load, when both cards are running in CF, is my Regor the absolute cause of the problem?

Please help if it is I will order the 1100T six-core.

definitely, My GF used to have the same CPU in her rig and when I dropped an Athlon II 640 in her system Skyrim saw a significant boost in FPS.

Edit: Also make sure that you download the latest CAP files from AMD's site.

Yeah I downloaded the latest CAP files and made no difference.... so is it safe to say that if I ordered the 1055T, my problems would vanish an I would get a decent gaming experience again?

Unless you are doing coding or 3D design the 1055T is overkill, look into the 965 or even better the 960T.

Well I figured I don't want to have to buy another CPU for a while, and the 1055T is only 150 bucks right now... the 960T is going for 125 bucks. So isn't it worth it to pay 25 bucks more for some overkill? Or will the 960T perform better for my setup?

Yes, you really seem to have a bottleneck. A CPU like that can't take a CFX of those cards.

And most definetly yes, the 1055T is more worth it. But if you can't dish that out, a X4 965 is great.

Thanks so much for the help...... The Regor served its purpose while I was playing Borderlands 2, and similar games, but now I am on SWTOR, and wanted to bump my FPS. Should I expect to see over 90 FPS on the Res Evil Benchmarks once I install this new processor tomorrow?

The 240 is one of my favorite CPU's. Built several systems with it and a single gpu. Overclocked the CPU to 3.5ghz each time. The strongest card I ran it with was a GTX 460 1GB with no bottleneck. Running it with dual 5770 Hawks, My favorite 5770, would be a little too much! smile.gif

Maybe. Resident Evil is more of a CPU intense game than GPU, so it might. 50-60FPS with just that Regor is pretty good, I'd have to say yes.

Haha... well I am a NOOB to crossfire setups, and I figured that even with a slow CPU I was going to see a least a slight increase in performance with a second card even with a bottleneck. So when I saw my performance drop DRASTICALLY.... I kinda freaked.

Well you live and you learn.... haha. Once I upgrade to a new MOBO that is 16x DUAL, I will see more performance as well.
