Kingston Server Premier DDR5-5600 ECC RDIMM 1x64GB

Kingston bumps this Server Premier RDIMM to 5600 MT/s, which sits toward the faster end of grades sold under that name, with CAS climbing to CL46 to match — DDR5 generally trades higher transfer rates against looser absolute latency, and this kit sits on that curve like the rest of the range.

This kit ships as 1×64GB for 64GB. Registered DIMMs like this route through an onboard buffer chip, which is why server platforms can run far denser memory configurations than a desktop board manages, but it also means the module needs a memory controller built to expect that buffering.

Every module in the family is ECC, and none of it is meant for a standard desktop socket — check the server or workstation board's own supported speed list rather than assuming 5600 MT/s is guaranteed at every slot.
