I have 2gb ddr1 geil value ram, would finding another geil value 1 gig module on mm help me with game stutter do you think? Getting pretty sick of lag spikes despite me upgrade from x1950pro card to a hd 3850. Sure the fps improved but lag spikes still noticeable. Also if i got 3gb of geil value ram would it be still dual channel for the first original 2 1gb slots?
