Read the threads. All infos are there.
Anyway try to get the core to over 1900 Mhz and the ram as high as possible (stable).
Use ram timings.
I have already done so and so far these are my stats which are running stable at 38.5 mhsh.
MSI Afterburner
Core Clock +150 Mhz
Memory Clock +800 Mhz
Power Limit 84
Any other fine tuning I am not seeing in a lot of places even outside of the forum but the minerstat website generally is correct about a card hashrate so what I am doing wrong ?
