Kingston Launches 24GB DDR3 Memory Kit HyperX T1 Black DDR3 triple channel memory kits are available in flavors of 6GB, 12GB and 24GB. 6GB uses 2GB modules, while 12GB and 24GB kits both use 4GB DIMM modules. The memory works at 800MHz in Double-Data Rate mode, hence the DDR3-1600 designation. Latency is the same for all modules: 9-9-9-27. The "T1" in its name comes from support for 1T Command Rate, a rare feature these days
