Hi, great Beam hashrate, but I have lot of rejects (20-30%) on nicehash on poolside.

Gminer, and Bimer are slower, but without rejects
Hi cervajz,
Thanks for reporting this, we will look into this.
Could you tell us which GPUs are you using?
Also could you post here a bit of miniZ log? Or a bit of the console output.
Cheers

I have rtx 2080ti and 2070
GTX 1070ti and 1070
Drivers 430.39 and 419.35

I had 6-10% rejected shares on pool during this log.

Hi cervajz,
thanks for your message.
We can see that nicehash, after sending a new job, does not accept submissions from previous jobs. Some pools still accept it, others like nicehash do not.
We've tested and managed to see that when the miner receives a new job, just before submiting a solution from a previous work, this results in a rejected share from that submission.

We will look into this, but we would not like to remove this submission because we do not think that miners will gain anything from it.
You'll get better efficiency on the pool, but you will earn the same (since nicehash does not accept it anyway).
As we said before, some pools still accept these submissions.

Could you check whether you notice a large difference from the hashrate reported by the pool and by the miner? Mind you that, for a better stats, it needs to run for a while.
Cheers
