Just started ethereum mining as a hobby and I'm struggling to get my rig stable. I get OpenCL hang after 6-10 hours at stock settings and hash rate fluctuates between 23 Mh/s and 24.7 Mh/s and sometimes drop to 19 Mh/s or 20 Mh/s for a few moments.
My rig...
2x Asus Radeon RX 480 8GB Dual Video Card
Gigabyte GA-F2A88XM-D3HP Micro ATX FM2+ Motherboard
XFX XT 600W 80+ Bronze Certified ATX Power Supply
AMD A4-6300 3.7GHz Dual-Core Processor
60GB Kingston SSDNow
8GB Corsair 1600 DDR3
Standard ATX case - no risers
Windows 10
Claymore dual miner 8.1
Driver 16.11.5
17-18GB Virtual memory, aero desktop disabled
I tried various 17 drivers but they don't make any difference. -gser 2 in claymore doesn't help either. Temps are held at 75C fans are 65% and 34%.
I've tried power limit -10 makes hash rate fluctuate a bit more and can't do more than -15 without crashes.
Tried memclocks one card can go to 2100 the other 2050 without crashing quickly. Not run the cards for any length of time at these clocks.
I read about -25 power and 2200 clocks so I think this is too low.
My feeling is the PSU is weak and I'd really appreciate some advice before I invest in a 1000W future proof PSU based on my hunch. Cheers.
