Here are three new pairs of fast DDR3 sticks shown at CeBIT:

• Corsair DDR3 @ 2133MHz (PC3-17064) shown running at 8-8-8-24-2T
• OCZ DDR3 @ 2100MHz (PC3-16800) specified at 10-10-10-?
• Patriot DDR3 @ 2000MHz (PC3-16000) specified at 8-8-8-20 but may run at 7-7-7-20

Corsair: Apparently the modules are only rated for this speed on yet unreleased Nvidia 790i boards.

OCZ: I don't like the thick water cooling heatsink jacket it will make it impossible to install two pairs of DIMM's on a board

Patriot: I like the slightly conservative ratings; if it really works at 7-7-7-20 @ 2000MHz it will rock.
