Re: Asrock H81 BTC Pro Board and Sapphire R9 290X Tri-X

I know a lot of people say you need a decent amount of memory for scrypt mining but I still don't understand why. If I look in taskmgr I see cgminer taking up ~55MB. I am using two 290's. Thoughts?

A lot of people are clueless. I have 5x 290s per mobo with 4GB of ram, and never had an issue. 2GB of ram should be more then enough for a linux miner. That said, the distros like bamt are messed and seem to eat RAM, but my gentoo installs have 90% free memory no matter how many cards are installed.

The Asrock BTC boards will run 5 or 6 R9 290s no problem.

I am curious on your 5 card rig what are you getting per card? Do you ahve the 290 or the 290x's? What model card?

Right now I have 3x 5 card rigs, all with R9 290 (non-X). I get 900KH/s/card consistently (899-901KH always). I also have a 4 card rig with Sapphire R9 290 Tri-x cards, which all get 945KH/s/card consistently except for one card that won't take the memory overclock and runs at 905KH/s.
