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)
2x6780 and 2x5770. Was 1000 kh/s with scrypt, now 480 kh/s. Seems legit. Using 1.5.3 of vertminer, and yeah 1.5.2 gives only hw errors.
