Nicehash compatibility

[kyleboddy]

Getting a lot of rejected shares despite checking the "emu nicehash" option. Any idea what the issue is?

[JerryWm]

What error does the pool send? (Click on "Reject" in the "Shares" panel)

[JerryWm]

Also support the miners mode of operation nicehash?

[kyleboddy]

Yes, I am using xmr-stak combined and have "use_nicehash" set to TRUE. The errors are nonce-specific "does your miner support nicehash?" issues. I mine on nicehash with these miners with no problem w/o proxy.

[JerryWm]

So do you use nicehash pool ?

[JerryWm]

You need to use either my miner (but it's only for cpu and the code is closed) or use 1 to 1 proxy (Max workers = 1 Emu nicehash = false)

[JerryWm]

Stratum-Proxy-XMR/src/app/StratumProxy.js

Line 62 in 45a1c10

this.nonce1byte = parseInt(this.nonce1byte) | 0;

There is a mistake. Incorrect parse of nonce nicehash

[JerryWm]

Download the source. Now everything should work. And try again this method.

Thank you!

So other GPU miners won't work in this setup?

xmrstak/claymore/sgminer -> stratum-proxy -> Nicehash

[JerryWm]

The miners do not support the proxy server and Nicehash at the same time. Since nicehash itself is a proxy server, it accumulates miners. This is due to its specification, which is supported by most miners.
Because of this specification, it became possible to create a cumulative proxy that runs on conventional pools.

[JerryWm]

But you can proxy 1 to 1. Then it will work on nicehash

[kyleboddy]

So for six miners, six instances of the software running? Or six pools of nicehash in one worker with max worker = 1?

StratumProxy only supports failover, not fractional pooling though, right?

If 1 to 1 means one proxy per miner, then there's not much point in doing that.... right?

[JerryWm]

In order to specify proxying 1 in 1, you must specify in the pool settings [Max workers = 1 Emu nicehash = false]

[JerryWm]

Look. If you dig at the nicehash pool, then 6 miners will have 6 connections to the pool. All of them will be visible on the "Pools" tab.

StratumProxy only supports failover, not fractional pooling though, right?
If you dig on the pool naisheesh then yes. But around a bunch of other pools, and on them you can combine up to 256 miners.

[JerryWm]

If 1 to 1 means one proxy per miner, then there's not much point in doing that.... right?
It turns out so.
ps. You can use mine cpuminer, it can be combined and with a pool of nacehash.
