ok so i have the same problem. I have the msi ref oc model as shown here......
http://us.msi.com/product/vga/R7970-2PMD3GD5-OC.html. Mining Litecoins and i struggle with the 500 range. Highest I have hit is 560 khs. I have tried every config. New drivers, new cgminer etc. I even went as far as to try and flash the card... Key words try to flash the card. IN my experience flashing has been easy. Usb stick formatted, throw your bios on there w boot files, and atiflash, reboot flash and your golden. This msi card is running me up the road. When starting the flash atiflash.exe -i 0 I get adapter not found, that problem occurs with any pcie slot number i put in. I have the big bang marshall so I have 8 pcie slots. If I just force flash using atiflash.exe -f -p 0 GIG.rom I get the adapter not found error 0fl01... which usually refers to a bricked card.. My delimna, this card has never been flashed, nor has the bios been edited. SO why am I getting this message.?
Being stubborn and not ready to accept failure I decide lets flash this bitch in windows using atiwinflash. LOl FAIL... not even atiwinflash will work. So I decided maybe I can use the msi live update from their site, and auto install new bios...... I download the update install it, andf it says my bios are up to date.
What is confusing me is the settings that Im changing should give me more than just a 5-10 kh/s bump.
Before we start hashing out the easy noobie answers remember or keep in mind Ive been piddling w bat files, and cgminer configs for a week now. And, have tried just about every setting out there. My sweet spot is 1070/1500 which produces 560 kh/s.
The flashing is also confusing me, like I said Ive flashed several cards.. 5850s, 6950s,6970s,and 2 other 7970s, never seen this error.
