<font color=blue> A quad SledgeHammer board can support 16 GB (4 x 4 GB) at 21.6 GB/s!

For example, a motherboard for a single ClawHammer is now limited to 2 GB of PC2700 DDR SDRAM -- 2 DIMMs (1 GB each, max) and 2.7 GB/s bandwidth. Thanks to its dual-channel design, a single SledgeHammer can support 4 GB of memory at 5.4 GB/s aggregate memory bandwidth (according to documentation, SledgeHammer can support 8 registered DIMMs, so it may, in fact, support more). A quad SledgeHammer board can support 16 GB (4 x 4 GB) at 21.6 GB/s! Of course, 4 memory busses and the associated DIMM sockets would be a significant expense, but since many 4-way motherboards support 16 DIMM sockets anyway, we may yet see such systems based on AMD's SledgeHammer. Thanks to relatively low pincount, high-bandwidth, and flexibility of HyperTransport, Hammer can deliver bandwidth numbers never before seen in the x86 world.

Very nice aceshardware.com
