When I go to download ubuntu, the download says 32 bit (recommended), and then 64 bit. But I think I'll need to get the 64bit machine for a mining rig?
I don't know if there's a difference in performance between the two. Doesn't look to be. But 64 bit is definitely *NOT* needed. I'm running dedicated miners on both 32 and 64 bit versions.
Isn't 32bit only see 4GB of ram? I have 4GB ram on the machine, plus 4 x 1GB GPU, that's total of 8GB of ram, wouldn't that cause a problem with 32bit?
