Sapphire HD 5770 issues

try download catalyst 10.2 (the newest ones) from amd website, i think they're awesome. working fine on my 5850. and check your gpu temperature on load too.

I downloaded 10.2 and they do seem to be working better, which I am thankful for. I also came to the conclusion that my case sucks so i took off the plastic window for cooler air to get to it, but that seems to have helped it a lot

so its all sorted out now?  

It worked for while, and now I am experiencing shaky screens and random restarts constantly, like 5 a day. I have the fan turned on at 85 percent all the time and im really starting to think that this is just a defective card. which i am really not happy about. I only use it to play wow but i have experienced the restarts not only in game but also when i am simply surfing the web. Do you think I should RmA it?

What's your PSU? Might also be a power issue.

Cheers!

My complete system specs are

4 gb gskill DDR3 1333 MHz ram
amd phenom IIx4 925 2.8GHz
Sapphire HD5770
WD caviar blue HDD
Asus M4A785TD-V EVO motherboard

and since that motherboard has onboard graphics i had to disable them and switch the primary video controller. It was at GFX0-GPP-IGFX-PCI. and i switched it to PCI-GFXO-GPP-IGFX. The other two options are GPP-GFXO-IGFX-PCI and IGFX-GFXO-GPP-PCI. I was wondering if this could have something to do with it and If i selected the right one. i really have no idea what they mean and my motherboard manual didnt give me a explanation of them and i was wondering if you had any idea what they were. thank you for all the help, sorry about the delayed response time

i have a thermaltake TR2 500 watt PSU. I know the requirements for the 5770 are a 450 watt or higher

I think that's the order in were the BIOS searches for Video devices. IGFX I'd say is the integrated video and the PCI is for a stand alone card. The others might be for Hybrid XFire and XFire.

Cheers!

so would it be safe to say that the one that starts with pci is the correct one to have if running a single card which i am?

If my assumption is correct, yes.

Cheers!

The 10.2 drivers do seem to be pretty good. Given you are crashing periodically, you might try 2 things:

1) check your system file integrity (bring up command window as administrator, and type "sfc /scannow"). If you have integrity issues that can't be fixed by sfc, you can examine the sfc output (start notepad as administrator, open the file C:\windows\logs\CBS\CBS.log, and look for the string "cannot"). The output will specify what files sfc believes are no longer good and should be repaired.

2) debug your crash dump file (C:\windows\MEMORY.DMP ?) by downloading and installing the Windows 64-bit debugger (windebug) and running the following command in the debugger: "!analyze -v;r;kv;lmtn;lmtsmn". This will give you some insight into where you are crashing.

Hope this helps!

I went ahead and RMA'd the card but If this keeps happening with the new one, ill definitely take a look at that , thank you for the help!
