My friend has a 6 card mining AMD rig, Now I have a good deal of experience with rigs. He is using claymore
The problem that he came across is as of today 1 pm (he has his rig to auto restart @ 12 pm) his hash rates went down from 180 mhs to 130 mhs.
He tried to some stuff and nothing worked. He called me up and I said I'll look at it. So since 6 pm today till now 10 pm, I have reinstalled drivers, OS, updated Claymore, tried new power supplies, pretty much everything other than swapping out the mother board.
The miner starts off strong, but then all GPU's other than GPU 1 slow down. All different amounts GPU 0 slows down a bit to 25, GPU 2 slows down to 10, GPU 3 goes to 20 GPU 4 and 5 go to 22.
This is why I thought power was the cause at first, but tried 2 separate power supplies and 2 break out boards, and 2 power supplies for the mobo.
All same results.
Anyone come across this problem?
PS I have tried the combined hacked driver for 6 cards, the latest drivers and the block chain driver, I also though it might have been the block chain driver as he said he updated it 24 hours before the slow down. But no avail.
I even took a clone of my hard drive that I use 6 card rig set up (both him and I use the same mobo), and still the same problem.
I am really baffled what is going on. I've looked around a little on some mining sites, haven't seen any problem like this. It doesn't seem to be associated with any hardware or software. Unless windows did a silent update over the past 24 hours that is the only thing I can think of. My rigs are set so they don't update :/ So my cloned HD should not have come across the issue he is having.
Edit I forgot:
Also tried dual mining vs single mining vs intensity of second coin, same problem, its just weird.
