Hello all
Can any one tell us 290x clock and memory settings to get best zec hash rate
Also I want to know 280x setting

SAP R9 290X TRI-X 8GB (1040/1400/-31mV) - 210.807 H/s (can perform better)

MSI R9 390X GAMING 8GB (1100/1500/-31mV) - 240.956 H/s
SAP R9 390X NITRO OC 8GB (1100/1500/-31mV) - 240.293 H/s
SAP R9 390 NITRO OC 8GB (1100/1500/-31mV) - 227.941 H/s

min.925 - max.1120W

stock bioses and Auto fans with custom curve via MSI Aferburner 4.3.0

H97 Anvrs, G1840, 8GB RAM, 80GB HDD, 16GB swap, Win7-64, crimson 15.12, Claymore's ZCash AMD GPU Miner v7.0

For stock hawaii DPM4 normally works, add -100mV + mem 1125/ 1250 and you will see some nice power savings. Performance hit is normally 10-15% but that is not a problem with these profitability levels.

Antantti thanks for your advise!
