Re: PhoenixMiner 4.2c: fastest Ethereum/Ethash miner with lowest devfee (Win/Linux)
I get the same speed on any drivers allready about 2 years.
On phoenix I have a bit more speed than Claymore. If I use double kernels (2x more vram needed) I got additional 200-300 kH.
Phoenix allways faster Claymore with the same core and memory clocks even on usual kernels. If you get lower speed on Phoenix, you forget to find optimal -gt parameter values for your cards.
With use of AMD Memory Tweak Tool it's possible to get additional 500-1000 kH of speed.
One of my RX 580 8Gb cards - Sapphire with hynix MJR memory gives on Claymore 33,5-33,7MH/s with -REF 90 on AMD Memory Tweak tool. And 34,2 MH/s on Phoenix with double kernels. About 34MH/s with usual optimized kernels.

Just tried ref 90 on 4gb hynix Sapphire got a small bump to 32,6
guess 4gb cards cant go more than that
Just tried - set REF to 5 (default) - 32,9MH, REF 90 - 34,2MH
Speed didn't change immediately, just need 10-20 seconds...
