Overview

The KTD-PE556D4-64G is a 64GB DDR5 server RDIMM from Kingston, rated PC5-5600. It is a dual-rank module built with x4 DRAM chips (2Rx4) and organized as 8G x 80-bit, with eight extra bits for ECC (EC8). On-die ECC is also present, as on all DDR5 chips. The module runs at 1.1V on a 288-pin connector.

Timings are 46-45-45, so CAS latency is 46. The rated operating range is 0 to 95°C. These details help when you add modules to a server that already has DDR5 RDIMMs installed, since rank and chip width should match across a channel.

Rack servers running virtualization, databases and memory-heavy applications are the target. The KTD-PE556D4-64G is available New or Refurbished, with 1 year or 3 years of warranty on either. Share the server platform and the module count, and we will reply with pricing and availability.
