Any of you guys have a 8-10% difference between effective current hashrate and current hashrate ?

I’m using pheonixminer on ethermine .

Yes, I had a lot of stale shares with pheonixminer. So I switched to Trex and the problem disappeared. I'm using Nanopool.

But its odd cause my 1070 rig reports the same on all counts . The 3080’s are the ones with issues

Same problem here, my 2080Ti, 3060Ti and 1660 were all fine with PhoenixMiner, only the 3080s had stale shares

I tried using trex but i have the same result . What are the 3080’s u have and whats their Oc settings ?
