Hey guys, I'm having a problem with my rig, trying to get some input.
Basically, I was mining as usual, and noticed the mhash rate on some of the cards drop to about half their normal rate, I thought this was just a driver issue to rolled back the drivers. Then I began to noticed wild flickering, not regualr mining flickering on 1 or 2 screens, but all 3 on my eyefinity setup. Then I began to see artifacts and the computer shut down.
The whole thing is watercooled, I'm sure its not a heat issue, temps never pass 60 when mining.
A video of my rig can be found on YouTube searching "butterfly labs mining rig", by Joshv06.
The computer:
Shows video/ bios post with all cards unlugged, using onboard video
Randomly boots with 3 or less cards plugged in
When a card is plugged in, the screen turns off, then turns on to a black screen
I believe it is a PSU issue, possibly the motherboard. I don't know. Please let me know if you have any ideas, I want to get a replacement part tomorrow ans get it up and running.
Thanks
If it was motherboard, you'd have no post what so ever. They're really temperamental when it comes to malfunctions - apart from direct damage on slots, ports etc. Very unlikely to be GPUs.
DO CHECK FOR LEAKS, what you've described is symptomatic of a leak.
Failing a leak, PSU is crying. Borrow one, or take it out of your other machine and and see if you can get it stable with 1 card on load. If so, PSU. Alternatively, see if you can find a PSU tested, must be on Amazon for $10.
