Hello guys. I just started configuring my first rig. I have 4 RX 470 gpus . It works just fine until i get this error :
WATCHDOG: GPU 2 hangs in OpenCL call, exit .
After that it tries to restart the system but actualy freeze it. I have 1200 PSU so power shouldn`t be a problem
Any idea what it can cause this ? I have enough virtual memory set. The Gpus are not modded or anything . Just stock
There seems to be a problem with atikmdag.sys Fail . I have 16 gb of Virtual Memory
Might be a bad riser.
I had a situation when I opened a brand-new riser x16-x16 and used it for a while, everything was alright.
After a while, I reconnected the riser several times and after that when system is idle, everything was ok, but when I turn a miner on - the GPU begins showing 0S/S, hangs and restarts the PC.
Changing the riser helped... For a while, then some time passed and history repeated itself... Using x1-x16 riser in x16 slot helped me. I guess crappy risers were the problem. Ordered USB risers now, hope it will help.
Hope my experience helps. Anyways, try this GPU without riser to make sure GPU is ok.
