The "more RAM is needed" thing is pure unfounded bullshit.

If someone is only interested in mining scrypt or vertcoin (At its current N factor), I will say you are correct. Vertoin's N factor will eventually change (at the same pace as glaciers move - across land)

On other coins, that increment their N factor regularly, some are up to N=14. If you get more than 2 cards that run 4GB each, you'll want to have 8 GB system ram. The miner software has to allocate the scrypt buffer in system memory to start, and allocating a 3.5 GB buffer for 3, 4, or 6 cards just doesn't fit into 4 GB of RAM.

I just fired up 5x R9 290 cards at N=12,13, and 14, with 4GB of system memory for several minutes at each N. Seemed to compile/load the kernel and hash fine. This might not be the case on windows, mind you - I run a custom gentoo install on all my rigs.

Just interest to know. Is your Linux 64bit? My BAMT (32bit) on 4GB memory just shows me less than 2.6GB available.
what is your "cat /proc/meminfo"? Thank you.
