Title: PSU doesn't like mining skein? Post by: kisk on December 05, 2016, 12:18:58 AM I was playing around with MiningPoolHub's multi-algo switching and for some reason when mining skein my PSU will start making a slight ringing sound and after about 10 minutes it resets itself, shutting the computer off and rebooting.
I'm using a Rosewill 1200w Quark series (80+ Platinum) with 3x RX 480 4gb + 2x RX 480 8gb. All cards are stock, using driver 16.11.3 on Win7. I'm using MiningPoolHub's sgminer fork (here (https://github.com/miningpoolhub/sgminer/releases)). Command to start miner: sgminer --no-retry -k skeincoin -o stratum+tcp://hub.miningpoolhub.com:20527 -u myuser.myrig -p d=10 -I 25 What makes it strange is that sgminer is pulling roughly the same amount of power from the wall as mining other coins (zec/eth) -- 900w at the wall (yes, need to undervolt!). Since the power usage is the same, I'm guessing it must be the way sgminer is making my cards draw power. Has anyone else experienced this? I haven't tried any other algo's with sgminer, just skein (Digibyte). Thanks! Title: Re: PSU doesn't like mining skein? Post by: bathrobehero on December 05, 2016, 12:33:20 AM I think Skein is just using more juice than other algos because the miner for it is well optimized. But it should be fine though at 900W.
Have you tried only mining Skein with 3-4 cards? Title: Re: PSU doesn't like mining skein? Post by: kisk on December 05, 2016, 12:57:56 AM I haven't, only the 5. Of course bringing the intensity down fixes the issue but at the cost of substantial hashrate. I just don't understand why the PSU is having issues when skein is using almost the exact same power as eth/zec.
