@doktor83

Hi, first of all thanks for your great work.

I have an MSI RX 580 8GB gaming X (H5GQ8H24MJR SK Hynix), its hashrate is only 28.2 MH for ETH and 760 H for XMR (SRB Miner). I modded it with UBERMIX 3.1 straps (1500+). Do you think using PIMP MY STRAPS could I get better results?

Ubermix isn't for Hynix memories, try pimping your straps, put for example 1150/2100 you should get aroun 30mhs on eth.

Yes I know. They come from one click timings (jaschaknack) and even if they are not the best, they are quite stable for this card.
I'm going to try the "pimp straps" and I'll post the results here.

Results after a few hours of "pimp my straps" testing.
Note: previous results obtained with "one click timings" are shown in brackets.

ETH - Claymore 11.6
1150/2000/900 -> 28.5 MH/s - (n.a.)
1180/2000/900 -> 28.5 MH/s - (28.2 MH/s)

1150/2100/900 -> 30.1 MH/s, thousands errors/second with artifacts - (n.a. millions errors/second without artifacts)

XMR - SRB MINER 1.4.6
1150/2000/900 -> ~819 H/s - (n.a.)
1180/2000/900 -> 820 H/s - (760 H/s)

1150/2100/900 -> 843 H/s, ~ 125 errors/hour - (n.a.)

So for ETH I have a very small improvement from 28.2 to 28.5. Unfortunately I can not use the memory at 2100: too many errors and artifacts even lowering it to 2080, 2050.
Instead for XMR although with the memory at 2100 I have some error (I think negligible values) there is some improvement: from 760 H to 843 H.

In the next few days I will test other algos and miners then I will decide whether to stay with "pimp my straps" or switching back to "one click timings".

Hi!
For your MSI RX 580 8GB gaming X try 1190, 1200, 1215 or 1230MHz for core clock.

For Hynix mem try this strap: 777000000000000022339D00CE5153379055111230CB440900208400740114206A8900A00200312 0150F292F94273116 for 1500+MHz.

Alternatevely, you cand send me your bios and I can modify it for you.

All the best,
Sorin
