Update:

Decided to release a Winblows supported version.

I've tested it on 2 systems with Latest adrenaline version (one with a Vega gpu, the other with a 570) and confirmed working.

Check OP for link.


Please post results here. That's all i'm asking Smiley

Cheers guys!

@Eliovp, once again thanks for your efforts here getting it onto windows. Much easier for traditional Vega Users with PPTs and Overclocking tools to really test the limits of your tool!

For my part, I'm getting pretty decent results on ETH; Reference Powercolor Vega 64 on latest Adrenalin 19.3.3 drivers.
Thanks to Windward for getting me started on values for parameters.

Given the generosity of Eliovp in even making this tool available, I'm not gonna be the guy that takes and doesn't give back.

For those curious, here's what I put in a batch script after I honed in on parameters.

(PATH to folder where MemTweak is stored)\WinAMDTweak.exe --CL 16 --RAS 30 --RCDRD 14 --RCDWR 14 --RC 44 --RP 14s --RRDS 3 --RRDL 5 --RTP 5 --FAW 20 --CWL 7 --WTRS 4 --WTRL 9 --WR 16 --WRRD 1 --RDWR 19 --REF 17550 --MRD 8 --MOD 15 --PD 8 --CKSRE 10 --CKSRX 10 --RFC 244

Run before starting the miner. For some reason, injecting the timings when mining would crash the miner if FAW>17, but FAW>17 is okay if injected prior. Also, RC<44 led to incorrect shares being found. No guarantees of stability... I was simply looking for accepted shares w/o rejects in short runs. I need to read up as well on compatible RAM timings... lower RC seems to drive HR the most.

Happy to answer any Q's; also, memclock was 1107 and was using PhoenixMiner4.2c
                  

Thanks @Eliovp for your research and releasing this tool! I'm liking your 12 GPU Vega system -- how does it fare for compute use? I worry not all the slots are x16.

Thanks for sharing @N2DCRYPT!

19.4.2 got me stuck at 37 Mh/s and temp was in the 70s and climbing! I'd advise anyone not to upgrade to those.

I'm getting 48.5 Mh/s with a Reference Gigabyte Vega 64 on water @ 59 C with 19.3.3 drivers.
Was getting around the same @ 54 C with the block chain drivers, I'll probably downgrade back to those.
