I was given a 2 gig stick that has higher timings than the 2 1-gig sticks I currently have installed and I'm wondering whether it is better to have 4-gigs (3.5 or so really with Vista 32b) with higher timings, 7-7-7-20...or have less, but faster, ram with lower timings.... 5-5-5-15. My board allows me to have dual channels if I install the two 1-gig sticks in the 0 & 3 slots and have an equal amount of the two in slot 2. So, if I add this 2-gig stick I'll still have dual channel memory but not as fast. I'm tending to think that Vista would like the extra 1.5-gigs more than having the better timings. What say you?
