Title: 5gpu 2psu scrypt mining rig shuts down 1hour later Post by: jaitor on March 09, 2014, 10:41:50 PM I built the following rig:
5x SAPPHIRE TRI-X R9 280X 3GB GDDR5 OC (UEFI) 1x AeroCool Templarius Imperator 1150W 80 Plus Gold 1x HighPower Tech 1200w Gold Plus (HP-1200-G14C-GOLD) 1x Gigabyte GA-990FXA-UD3 motherboard 1x W.D Caviar Green 500GB SATA III HDD 1x Kingston KHX1600C9D3B1/4G 2x Unpowered risers 1x 16x 3x Powered risers 1x 16x I have the templarius PSU powering the motherboard, the HDD and 2x GPUs with unpowered risers. The other 3 gpus are powered by the 1200w PSU and connected to the powered usb risers. I Installed Windows 8.1 and plugged one gpu. It automatically installed the Radeon HD 7990 driver. Then connected the second gpu and followed the same process with the other gpus. I then executed cgminer and everything looks stable at 740Khs each. However 1h later the entire rig turns off. It always shuts down aprox. 1h later.. i suppose its not a power supply problem..

But also check the temps, I've never ran a miner without increasing the fanspeed manually, since AMD cards never increase it enough.

apt-get remove network-manager* This will set your bamt to static ip, helped in my case. Title: Re: 5gpu 2psu scrypt mining rig shuts down 1hour later Post by: Monty-Python on March 10, 2014, 11:03:38 AM I had the same issue with my rig at the beginning. These settings solved the issue:
1500 / 1035 is the combination that works on most 280x with tc 8192 also update your driver. this always gives results above 700kh/s Code: -I 13 -g 2 -w 256 --thread-concurrency 8192 --gpu-engine 1035 --gpu-memclock 1500 --auto-fan --temp-cutoff 95 --temp-overheat 75 --auto-gpu but make sure you've got the latest amd driver and if it's a beta driver try the one before that. Read my first post to find similarities, I am also using Toxcis. Rig has been running stable since. |
