Nicehash Extremely Low Hashrates from 1950x Threadripper with 2 CPUs Enabled #1482

I re-installed Windows 10. Before that, everything worked smoothly I didn't even bother with Virtual Memory Settings or Enabling Lock Memory Pages etc. I was getting 650 H/s from each card 1300 total.

Now if I run both CPUs I only get 300 hashrate. (150 each) But if I turn off one one of the CPUs I got 1200 H/s from only one CPU.

I think something goes wrong while benchmarking.

I got "Starting single thread, no affinity" error(?) 14-15 times after starting. And this is the hashrate report:

PS: I'm not using Legacy miner. I had no luck with it.

Any solutions for the issue?

Thank you.

im not very technical when it comes to explaining why it does this. But if im not mistaken and somebody could correct me if im wrong. It has something to do with how many pci lanes the cpu has going to it. if you enable too many threads the cpu sorta does this bottleneck thing where it actually hurts the performance of the miner. So as long as your getting 1200 total from one just leave it at that. I dont know how to fix it exactly but you would need to put a variable in the benchmarks configuration page that states "less threads=X" where x is how many you dont want it to use and find the number that gets you the highest hashrate when it comes to cpu hashrate ive noticed less is more . Hope this helps!
