New rig: I'm having an issue with HR dropping by 25%-75% for a second or two about every 10 seconds, sometimes less. NOTE: This is NOT the 9.x issue with dual mining where random cards drop 5-10Mh/s -- my problem happens with ETH only and 8.1 as well, and HR drops on ALL cards. I'll be a thorough as possible here. I hate when people post questions with little info:
Win10
AMD 16.12.2
CPU: Athlon II 170u 2Ghz (single core)
MOBO: Gigabyte 990FXA-UD3 R5 (all unnecessary options turned off)
8GB DDR3 (timings set correctly)
25GB VRam
60GB SSD
3x Gigabyte RX480 8GB (1750 straps)
3x Powercolor Red Devil RX480 8gb (1750 straps)
EthDcrMiner64.exe -epool us-east.ethash-hub.miningpoolhub.com:20535 -ewal user.rig02 -epsw x -ethi 16 -esm 3 -asm 1 -allpools 1 -mport XXXX -r 1 -di 530142 -dcri 10 -cclock 1145,1145,1145,1156,1167,1167 -cvddc 1037,918,1087,1031,1043,1037 -mclock 2150,2150,2150,2175,2175,2175
180Mh/s
The logs don't show me anything in particular out of the ordinary except for the drop in HR. I though it might be a power issue so I distributed the rig with 2 PSU's which didn't change anything. Tried 8.1, 9.0, 9.3. Set cards to default clocks. Tried ASM 0,1,2. multiple ETHI/DCRI values. Same. I did disconnect all 3 red devils and that fixed the issue. As soon as I connect a 4th GPU it starts happening again.
Couple things I'm thinking:
1) Maybe the CPU is too weak to keep up with certain functions? I have an Athlon 3.0ghz dual core on the way to test.
2) This motherboard does not have any settings for changing PCI-e options, gen1/gen2/gen3/Lat/etc. Maybe the lane bandwidth is hiccuping somewhere? I would think even 4 cards should be fine though, which its not.
3) I hot swapped this Win10 install from another rig (intel) and let Win10 reconfigure everything. Installed new drivers, and fresh installed video drivers. Maybe I'll try a full reinstall, or linux.
4) I don't think its a riser issue and it effects all the cards..
Hoping someone may see something I don't. Thanks for your help!!
