Oops, 64 bit only.
Guess I have to wait a week or so 'till my "next gaming machine" parts show up, as I don't have anything running a 64-bit OS yet (I do have Win7 64bit for the new gaming machine waiting).
I do have to wonder why they limit it to 64 bit only, does mining Ethereum take a ton of memory for some reason?
The Ethereum use DAG, it started from 1GB and it will rise 600 MB per year. Originally the PoW was planned to last long.
You like the convenience, but they're practically stealing from you since you'd get more mining on say dwarfpool and converting via an exchange. Also, pretty much any possible CPU you could have will run a 64bit OS without problems. 2GB ram is fine for 64 bit even, I actually noticed better real life perfomance on a workstation rig I did for a friend running 64 vs 32.
Yeah, most of the machines I have COULD run a 64 bit OS - but I'm a VERY longtime Slackware fan (moved to Slackware a couple years after Yggdrasil died from lack of choices - it was Slackware or SLS and I strongly disliked what I'd seen of SLS), and it's not real easy to run both 32bit AND 64bit apps on Slackware (mostly an installation of libraries issue, just haven't had a REASON to bother with it before now).
I might get around to biting that bullet this summer, though it looks like my existing vid cards won't work well if at all with Ethereum anyway (mostly 7750s and A10 integrated stuff 'till the parts for the new machine show up).
For the record, I doubt that some of my existing machines CAN run a 64 bit OS - AMD K5s with 16 megs of RAM are just a bit outdated and puny, though they still work to crunch RC5-72 (but they're slow enough I'm planning to retire them when I move, not worth the effort for space heaters given my current miners). Might retire the K6 machines too at the same time, except those are viable for replacement parts for my firewall/gateway/router box - and I don't have very many of those.
