Hi everyone,
I recently decided to switch all of my AMD rigs from ETH to XMR V7 on nano pool.
All of my R9 380's and R9 390's do fine when using Claymore Cryptonight GPU Miner (Latest Version for the fork). However, my RX 480's and RX 580's do not work properly. Only 4 [Sometimes 3] of the 7 cards for each rig mine while the others are 0.0 H/s. This forces the rig to restart the mining process over and over again 4 times; then the rig shuts down.
I even tried switching from ssl to stratum with same results.
Is this Awesome Miner I'm using doing this or Claymore Cryptonight (latest version) on Awesome Miner?
Again, no issues with the R9 380's and R9 390's. Only the RX 480's and RX 580's.
If someone happens to know the issue and how to fix it, I would certainly appreciate a point in the right direction.
Thanks,
David
Hi David,
Take a look about oc settings on RX 480 and 580´s, these cards need more core mv on cryptonight than eth. It depends the core speed youre mining at.
For example, if you normaly mine eth @1180 and undervolt 800-850mV, in cryptonight V7 you need 950mV at least.
This is not meaning more power consumption, whereas cryptonight is less intensive algo than ethash.
Hope it fix your 0Hs problem with these gpus-
Regards.
