In the world of high-end gaming rigs, it isn't size of your megahertz that equates to higher performance, but the multiplier on your bus -- if you catch our drift. Regardless, for most gamers bigger numbers will always be better, and when it comes to fast memory Corsair now holds the record with a 1GB stick of Dominator DDR3 SDRAM. Overclocking in at 2462MHz (supposedly the highest recorded frequency to date), it survived the brutal testing thanks in part to an integrated four-layer extruded aluminum sink, which helps shuttle heat away from your bits and into your case. Naturally, these numbers come at a premium: over $200 per gig. But if you absolutely must have the fastest, this is it -- for the moment.
