"We've seen some Kingston and OCZ DDR3 before, but what if we want something even /faster/? Way outside the stratosphere of the official JEDEC rating of 1,600MHz, we have Corsair making Dominator modules at 1,800MHz and some Super Talent at 1,866MHz. That's over /one Gigahertz/ faster than current DDR2 800MHz.

There is absolutely no doubt that these are blazing fast DIMMs using cutting edge technology - 1,800MHz equates to PC3-14400, while 1,866MHz is PC3-14900. However, the speed does come with a price and it's not even worth considering these absolutely premium modules unless you're the type of person who will buy the latest and fastest kit as soon as it arrives, regardless of cost. It does provide some future-proofing to a certain extent, because 1,800+MHz will still be faster than any motherboard can officially handle for quite a while yet - even the X48 chipset due out in January will only increase the official memory capability to 1,600MHz."
