memory timing

[chedderslam1]

I'm looking at two different sets of memory, one 2 gig one 4 gig. It seems that the 2 gig set is faster. Would it be better to go with the 2 gig set or the 4 gig set?

The two gig:
Timing : 4-4-4-12

The four gig:
Timing : 5-5-5-18

What do the different numbers mean? Would the extra 2 gigs of memory outweigh the slower memory performance? Or are the higher numbers faster?

lower numbers (or "tighter" timings) are faster on like sized memory, but to answer your question - 4 gigs at higher numbered timings will be faster than 2 gigs at tighter timings.
