Whats the fastest DDR2 Dual channel memory?

[teamhex]

i'd just get some low latency ddr 800.
my mushkin performance ram was like $50 for 2 gigs back in the day, and at ddr800 they're at 4-3-4-11-2t
you'll probably notice a difference from 533 going to either 800 or 1066, but ddr800 is more than enough, you're bottleneck will be the CPU or GFX

Could I get a link to a 4 gig kit? Or 2 gig kit I guess.
