okay so i restarted and the clocks returned to 700/1000 but still mining very slow. Is it normal for the pci-e speed to be so low?
So what are the 2 different cards mining at now? Still 200 and 50 MH/s?
PCIe speeds have almost no affect on hashing speed.
one is getting about 150mhash and the other is getting about 50-60mhash.. same model cards, they should run the same mhash.
If i damaged the card while repasting the heatsink/memory would it act like this? Or not work at all?
If the repaste wasn't done properly, or the heatsink isn't making proper contact, you could be running into thermal limiting. 300core and 400mem looks like a low power state to me. I suggested checking ULPS, but it could be an overheating issue. What are the temps of the GPUs?
