The fastest current memory we've found is not from the usual suspects at Corsair and OCZ, but instead from TeamGroup.

On its stand yesterday, we found 1333MHz DDR2 at a respectable 5-6-6-18, although the high chipset strap needed to run at this speed means your access latency is a huge 98ns.

In contrast, its DDR3 has not just reached the top end specification of the JEDEC standard, but it's massively exceeded it, running at 2000MHz. To get to these speeds at just 9-9-9-20, upwards of +0.6V (a 40 percent increase in supply voltage) needs to be used. A far better 73.1ns access latency is achieved, along with some 10,000MB/s read bandwidth - 40 percent more than a typical DDR3-based P35 board.

Both sets of performance modules have the huge ThermalRight heatpipe/heatsinks on them which have the two sets of extravagant fin arrays above the actual modules. The problem is that the heatsinks are so large, you can only fit two modules in dual channel, a memory slot apart. This makes it only suitable for Intel systems, as dual channel is available on AMD systems when the modules sit side by side.

To run at these speeds, you'll need to overclock your CPU as there is no chipset strap currently exists for native DDR3-1600MHz, let alone 2000MHz. TeamGroup was using an as yet unreleased Intel Core 2 Duo E6850 at a massive 500MHz FSB on a Gigabyte P35 board, using the 2x memory multiplier, giving a 1000MHz memory bus and subsequently 2000MHz DDR3 memory.
