Topic: Powercolor r9 280x good for mining? (Read 891 times)
I just finished a rig with 4 running on a 860watt PS. I've undervolted them and use SGMINER on windows 8.1. Getting 725-730 hash rate. Two are Elpida and two are Hynix memory. Just trying to figure out why one tends to go sick. Might tweak the voltage up a bit, or take a card out and see if it still persists. Otherwise, they seem ok, but I've only had them for under 2 weeks.
We have a bunch of the Powercolor 290 cards. They use the Elpida ram, and don't really go much higher than 800.
For 280x, stick with good brands: Sapphire, Gigabyte, Asus, or MSI.
