I have an issue that i can’t solve on my own. I have a rig that is running 4 x 1660 Super’s. For some reason, the hash rates seem to vary between the cards when mining on KAWPOW no matter the overclock settings or miner. However, this does not occur when mining other algorithms. For example, all 4 cards give me 31.77 to 31.78 Mh/s for ETH per card. With my current overclock settings for KAWPOW, GPU0 = 11.48 Mh/s: GPU1 = 11.05 Mh/s: GPU2 = 10.71 Mh/s: GPU3 = 10.69 Mh/s.
CORE: -100 MEM: -1004 PL: 85 FAN: 0
MOTHERBOARD: ASUS PRIME Z390P
GPUs: 2x ZOTAC & 2x MSI
PSUs: 2x CORSAIR RX650M
Tried switching over to NBMiner
Tried using different PSU and power cables to each gpu.
Replaced risers for each gpu.
Tested each PCI Gen setting in BIOS
Verified that ABOVE 4G ENCODING is Enabled.
