Miner- Optiminer/Zcash GPU miner v1.7!

As I have stated and many others as well, you cannot adjust the “Memory Voltage” using Polaris Bios Editor. That number does absolutely nothing to the bios and nothing to the GPU either.

The only way to get the results you guys think you are getting is by using one of the few GPU (Asus Strix comes to mind) that has a Hex value already in the Bios and then changing that using a Hex Editor. Otherwise you would need to add 8E to the VoltageInfo Table in the bios and the associated value for the Offset as well. That is the easy part because then you need to correct the ROM length and all the tables you screw up by adding those hex values. As well as some other stuff …

I am currently testing a new release with more stable stratum connection (reliable reconnect when pool disconnects) and fixed extranonce support. If it runs stable I will release it later today.

Quick question: When you test, do you test using a single card or multiple card rigs?

Looking forward to the next release. 3.1 was no good for me.

Please do not take offense to this:
I would not touch that bios with a 10 foot poll. It is a complete waste of electricity and will crash 90% of the GPU’s that use it. I will start with a few items wrong with it.

1 - As mentioned your “Memory Voltage” mod does absolutely nothing
2 - 1400 Core Clock is not going to be stable on most cards at boot and definitely not under load.
3 - You have not increased the power because it has a limit in the ROM. Try adding some mV to the DPM7 position and see what happens when you boot up— If you add to much you wont see anything but a black screen .
4 - You bumped up the core clock to 1400 and left the DPM7 unchanged, do you know the value of your DPM7-- if not maybe take a look at this:

ANd the list goes on and on. I would suggest reading about DPM, EVV, VID, VDDCI, MVDDC etc so you do not fry yours and other peoples expensive hardware.

Just my 2 cents.

This may be its intended purpose.

Game theory people.

If enough people used it the difficulty would go down due to wrecked cards. This is why I don’t recommend anyone download ANY modded bios unless they are suitably technically competent to know likely effects of using it.

It’s better to learn how to mod your own then at least you have some control over whether or not you burn out your cards.

I run a few of my cards with that BIOS, yes, some do even not start / crash / or overheat.

Those are just my VBIOS that I have been playing with, which I just shared.
But for the sake of caution, I removed that rom just to avoid that someone with not that much clue about BIOS flashing does not fry his card. :egg:

I did not think about that, so thanks for your comment on that! :slight_smile:

Anyone mining on flypool noticed payouts have been stopped? After crossing standard 0.01 ZEC, nothing happens for half an hour…

I had that happen to me yesterday but it was paid out. Wait for an 1hr or 2 and it should go through.

I had the same Problem, with the same pool. Which UTC you have?

My disconnect started at 2016-11-14 03:19:27,286 UTC

Woke up and noticed my miner seemed to have stopped on its own. Anyone else have this?

nope
i use script for auto restart if it is happened

Mine has been running for days without any issues. There was a point where my internet went out, but that had nothing to do with Optiminer.

I hope you did something about cpu

You might wanna lower the devfee as people already moving to Claymore.

Keep the fees up. There is stoll room to improve the hashrate. Don’t get lazy and drop the fee before there is no improvement left. :wink:

I’m not sure when exactly it’s started, my paste is when I saw it and I immediatelly restarted…
+2 here :slight_smile: right now the time is 17:20

Amazing equihash optimization, @Optiminer! We’re loving the bump from ~200 sols/s to ~800 sols/s on this 6x rx470 4gb w/ strap mod:

You can see the income per round on flypool, that wall on the right of the graph is optiminer.
