Low FPS from ATI Radeon HD 5770

[jchu14]

I don't have any great ideas fishingcat, but I have that motherboard and a Sapphire 5770 installed at the top slot (blue) that works correctly at x16.

I am using mb bios 1406, catalyst 10.2, and my SLI selector in the default single card position. I don't think I had to adjust any bios option either.

Running in a PCIe 1.0 slot will hardly make a dent in the performance, at least not on a 5770. I'm running one in a 1.0 slot and it works great.

No, that's not the same. If I read you correctly you are running a PCI-e v1.0 slot with 16 lanes. This provides 4GB/s of bandwidth. It's not great, but it's sufficient for most single GPU cards. The OP is running a PCI-e v2.0 slot with 1 lane. This provides 500MB/s of bandwidth. This is horrible. Absolutely shit. And it will completely drain away performance.

The problem certainly does appear to be the MOBO. Have you tired resetting the CMOS afterwards? That is changing a particular jumper and removing your MOBOs battery for a bit before reinstalling the battery.
Also when you say the "second slot" do you mean the top blue slot in the picture posted or the black slot in the middle of all the slots?

I am going to try the card in a friends PC to make sure there is nothing wrong with the graphics card. Also some people have fixed this problem by putting the card in a different motherboard and then putting it back in the original.

Tried the card in a friends PC and it worked correctly at x16, still only runs at x1 in my PC though. This means it's almost certainly a MOBO problem.

New motherboard time man welcome to the pain of upgrading.

That or just setting everything to defaults. You tried it in another computer, so it's not the card. Maybe your board just doesn't like this particular card; sorry, not much a solution.

Your system is still pretty good, so swapping out the mobos for a budget P45 (right socket?) should be worth it. Or do an RMA, but considering the hassle of that with no guarantee...

Have you over clock your CPU? If yes, try to set the PCIE clock to 100MHz or 102Mhz, and see if it can be improve.^_^
BTW, you can also check your system temp. (ex: VGA, NB) to see if there is something different.
