Hi guys.
On Claymore 10.6 i had 550 hours on a row on nanopool, last time i upgrade to 11.4 2 days ago, no issues and hashrate was +0.5 better sometimes and sometimes just -0.5 less than the reported, most of the time...i had more average than reported, which is crazy. I upgrade tot 11.4 and my average hashrate drop to around 5 to 6 mhs less... I check and note down my average 24 hours hashrate 3 times per day and in 550 hours i had the average almost as the reported. With 11.4 although i have it only for 2 days, i never went beyond 187.0 mhs although i have 192.9 reported...over 5 mhs average lost in the dark. So 11.4 is broken, something is working really bad right there. I will let it run one more day, but im sure the 11.4 is garbage, thats all and i will stay with 10.6.
Good luck!
I had similar results, however over the last 12 or so hours I have had several cards lose their over clock and some rigs go offline. I've updated to 11.5 for the rigs having trouble with the oldkernels flag. Let's see if that is better.
I'd say I had a rock solid setup prior to 11.4, since 11.4 33% of my rigs have crashed.
