Hi Mattthev,

like many others I am new to mining and GPU OC.

Here is the situation:
Recently I discovered

Gateless Gate Sharp 1.1.18: zawawa's open-source dual ETH/XMR/PASC/LBC/FTC miner

and I actually have great success mining Cryptonight with zawawa's miner.

I mean a hash rate of 1,070 h/s for each RX 580 is not bad at all.
With Claymore's I never had more than 1,017 h/s, which is also not bad.
Ethash is working ok at 28.5 mh/s (Claymore's 29.2 mh/s).
If I understood correctly zawawa is currently implementing Equihash.

Anyway, with some recent release zawawa's miner became unstable on my rig (6 x MSI Radeon RX580 Gaming X 8GB with Samsung memory).
With v1.1.14 the miner stopped once a day (with i'm using right now with a batch in a loop because the monitor is not reliable).
But with v.1.1.19 the miner restarted 13 time last night (with the monitor working perfect).

To remove support requests (of my kind, I guess) zawawa does not support bios modded toward Claymore's any longer.
Which is fair enough.

Zawawa is doing a tremendous job answering all forum posts, bug fixing and implementing new features etc. all at the same time.
Therefore I belief zawawa deserves the 1% devfee and I really want to bear with him.

Currently my bios is modded with the UberMix 2.3 timing strap copied to 1:1500 and up taken from the source code of jaschaknack's PolarisBiosEditor v.1.6.4:

And the Good HYNIX_2 copied into 2:1500 and up (which was necessary I have learned afterwords):

Would you be able to mod the bios for my RX580 specific for Zawawa's miner?
If so, how many beer's would be required?

Cheers

I'm not much familier with that miner I tried it once, but there are too many things to config in GUI... I'm not fan of it.
What are your core clocks? You ETH hashrate is pretty low for the XMR hashrate... So you probably have core clocks pretty high.
Try Uber-mix 3.1 like almost everyone else, decrease the core clocks or set higher voltages, watch for memory errors.

Understood. Either you like GUI or not.
I see it the way that I don't have to read all Readme.txt just to find that single option I'd like to tweak.
And that for every miner/algo and re-read until memorized.
Possibly you have passed that stage long time ago.
With a GUI I just look for them and apply my adjustments.
If you need to change any option is a matter of how good the author has set the default values.
I for myself don't have to change any option, just select pool, add wallet address and press the start button.
But as I said, either you like it or you don't.

My core clock is at 1300, memory at 2000 and no changes to the voltages.
With the latest AMD driver afterburner does not work any longer and WattMan is a pain in the butt.
Takes ages to set 6 cards and if the driver crashes you have to start all over.

As almost everybody I tried UberMix 3.1 as it is the default timing you get when using PolarisBiosEditor v.1.6.4 one click timing.
But I never got it stable with good results on my rig. Either stable or good results, but never both together.
And with stable I mean running for at least 12 hours without failures.

I also tried UberMix 3.2 but I am not sure if it is good at all. Never got a single share mined with 3.2

That's why I was aiming for a tailor made mod.
Soon Zawawa will have Equihash integrated into GGS.
If that is as successful as it is with Cryptonight I really would like to use the latest version.
