Im wondering if anybody can help.

My experience with the amd threadripper 2990wx for mining is not good.
Firstly i tried using monerod solo and next the claymore pool miner. after downloading the monero block chain i set the threads to 16 and i got about 8/900 hashes. In claymore i was getting 11/1200 hashes.

Tried setting to 32 thread but now the hash rate dropped by approx. 25%
Tried 48 threads and it dropped another 25%
And at 60 threads i was down to below 200 hashes.
I am a bit peeved with these results- maybe its to do with windows 10 1803.

Running an instance of monerod solo and claymore pool together with 16 threads each, starting one at a time did not cure the problem either. When the second miner started it stole hash rate from the other miner and vica versa. I have the amd power mode installed set at balanced. ive tried setting registry cache memory values, memory behaviour bias to 2 but no differant
It seems the best thread count is 16 - no matter how many miners are running the total thread count cannot be more than 16 to get best results

Hopefully a fix can be found. Any thoughts anyone?☹️
