Re: [ANN] YACMiner - AMD GPU miner for Scrypt-Chacha, N-Scrypt, and Scrypt coins
I'm really struggling to get a decent YAC rate out of my three MSI R9 290 (4Gb) cards; the best I've managed so far without a load of hardware errors is a little over 5kH per card which seems too low to me!
I've tried to go through the tuning guide in the readme, have tried 2, 4, and 8 for lookup gap, but still can't do any better. Can anyone help please?
My "best" settings so far:
Edit: I'm running Windows 7 64-bit with 8Gb of system RAM, using the above settings Task Manager shows 1419/8153 memory in use (so well over 6Gb of physical memory available)
