Tried many drivers with overdriventool,win 10 ltsb,no memory errors,compute enabled etc so its not oc,ping is normal around 30-40ms.Images are pool side,miner side looks stable and ok,variations in miner are 1-2mhs up and down sometimes,tried clkernel 2 but drops are worse miner side.Anyone have any clue?thx
