If using Windows, get a second 4gb stick...4gb is enough for linux, barely cuts it for win.

Not kidding, it won't work...I run both win and linux mining rigs. (curecoin needs win for now :/)

Just 2 gigs of ram on both of my rigs (win7x32) and vertminer runs excellently. No errors, no stales. So this is just a bs about needing more ram.

2gb is BS...what was your hash rate wise guy? (and what gpus)

I'm running on 4gb on my 4x7970 rig at 370kh/s each and 2gb on my 4x5850rig at 170kh/s each. It's all about tuning.

4gb for a 280x rig is ok, but 2gb is impossible. I tried, and had to settle with multiple threads and lower tc, which slowed it down.
