The DFI LANParty UT X58-T3eH8 was chosen for today’s test platform by comparing test results from our own reviews to those of various memory manufacturers.

Winner of our previous High-End DDR3 comparison, Kingston sent a newer set of its KHX16000D3ULT1K3/6GX modules to represent the latest memory ICs. The new modules have larger identification labels but otherwise appear identical to the originals seen below.

The retail-boxed Dominator GT DDR3-2000 CAS 8 memory kit includes a fan, but we also wanted to try out Corsair's new thermoelectric cooling device. Though Corsair has its own external liquid cooler capable of handling this small thermal load, we stepped up to a custom component-cooling configuration from Swiftech, which will hopefully improve overall performance even further.

Swiftech’s MCP350 pump provides excellent coolant flow for 3/8” flexible tubing. The company’s MCR220-QP radiator provides around twice the surface area compared to typical external liquid coolers, while its integrated reservoir reduces clutter. Two MCB-120 Radbox Revision 2 spacers provided space to mount the water pump and wall-hang the assembly, while maintaining unrestricted airflow to and from the top fan.
