Hi Guys.
My "rig" running with the latest version of this miner more than 24 hours, and I have lot of rejected shares.. around 20%
I use two Asus RX580 card, GPU0 is DUAL-OC-4G with Eplida memory, GPU1 is ROG-STRIX-O8G with Hynix memory.
I tried more BIOS mod, and default BIOS and lot of settings, but the results is same... any ideas?
Here is my log:
...
[2018-11-30 17:39:09] Pool xmr-eu2.nanopool.org share accepted. (GPU0) (a:1559 r:29) (76 ms)
What is the "rejected share" exactly?
A rejected share is simply when the pool does not accept a share that you find and submit. The most common reason is that the share is submitted for an old job. CN jobs on the gpu take a while to compute, so in some cases a new job is sent out right before a job completes. Added network latency exaggerates the effect.
However, you don't have 20% rejected shares, you rather have 29/(1559+29) = 1.83% rejected shares. I'd say it's on the high side, but nothing too crazy. I don't know Nanopool's policy for accepting shares for jobs for the same network block height though.
