Im currently running vista with 2gigs of memory and am really tempted by the low prices of ddr2. are there any known issues with running 4gigs in vista?? can i still successfully overclock??
im using a asus P5W64 ws professional motherboard and 2 1gig sticks of 6400
Go for it been using 4gb with ultimate 64 for a while and i'm loving it to bits. Don't worry about overclocking if u have a good set of ram it will be fine, i can keep my Q6600 @ 3.6ghz even with my 4gb of ram at 1400mhz(ish) (reaper 1066 4X1gb).
been running 32bit and 64bit vista ultimate on 2 sep drives using 2 x 2gb OCZ PC5300, not done enough with either to see any benefit apart from 4gb showing up in my computer
