Kingston has Westmere-EP-ready DDR3 memory
 

Beside approving the new 2400 MHz HyperX kit, Intel has certified three Kingston ValueRAM DDR3L registered DIMMs for use with the new Westmere-EP server processors. Kingston's modules, a 1GB Single Rank x8, a 2GB Single Rank x4 and a 2GB Dual Rank x8, work at 1333 MHz with CL9 latencies and are powered at 1.35V which makes them low voltage.
