My sapphire 7950 on a computer with 4gb ddr2 cannot go past -i 13 without getting hardware errors, I've tried thread-concurrencies for hours. Currently it's only doing 160kh/s
Yes! Same problem here, what the hell is this.. Anything over 13 gives me loads of HW errors on Sapphire 7950 Boost.
need 8G ram
You are wrong. I have another rig with 4x 280X, 4 GB RAM, and it works fine. This one was just 2x 7950 and 4 GB RAM, and had the issue.
The solution is to run these cards with gpu-threads 2 and intensity 13. Getting stable 300 KH/s per card and no errors.
