Hi

I moved to PhoenixMiner from Claymore to be able to mine ETH a few more months with my RX580 4GB cards. I understand there is no -strap or -rxboost option for AMD cards. Do you guys use a seperate tool to apply straps or did you flash the cards?
The straps provided by Claymore was a bit better than the timings that I flashed to the cards. Win 10


Yeah you can use AMD Memory Tweak

I recommend you to first run with Claymore and open AMD Memory Tweak to check which parameters have been set then copy all these values, switch to Phoenix Miner and set those values after 1 min or so. You can use a simple batch on Windows start up to set these values after the miner is up.

Strong recommend you to find out which -gt number is the best and fix it on the config file

My config

Asus RX 580 8GB samsung memory

30.1 Mh/s

--R2W 31 --RC 75 --RRD 5 --RCDRA 26 --RCDR 26 --RCDWA 14 --RCDW 14 --RFC 184 --RP_WRA 55 --RASMACTWR 33 --RASMACTRD 28 --ACTWR 9 --ACTRD 10 --RAS2RAS 101 --RP 24 --WRPLUSRP 30 --REF 45

-cclock 1100
-cvddc 800
-mclock 2050
-mvddc 825

Thanks, but according to deadsix (one of the latest post in the AMD Mem Tweak thread) it's not possible to read the timings from the card. This is however not important if there is another way to find a good strap. I have 580 Nitro+ 4GB and suppose it's the most used card in mining.
There is a GUI and a CLI version but no explanation on how to use them. You run the CLI version followed by the settings you listed? --R2W and so on?
