Whats the difference between this memory

[Exibit]

Hi guys

I'm looking to buy 2G of memory and want something that will run in SLI mode and also give me bang per buck in the long term, I use my pc for gamming

Both produced by OCZ, the first one listed seems to have a higher voltage and also can be water cooled but is that it ????

Will they both run at the same speeds

the kit with the heat pipe has tighter latencies of 5-5-5-15 and is only rated at 1150MHz DDR2, whereas the other kit runs at 5-5-5-18 latencies and 1066MHz DDR2

Still not clear when I look at the specs they both run at 5-5-5-18 and both at 1150MHz

No difference except the former can be watercooled.
