SK hynix 64GB DDR4-2666 LRDIMM ECC 4DRX4 Server Memory

This SK hynix module is a 64GB DDR4 LRDIMM ECC rated at 2666MHz, labelled PC4-2400T-R (4DRX4 organisation).

Capacity per module decides how much headroom is left for later: larger modules keep slots free. Buying in matched sets makes it easy to fill channels evenly on every processor. For the best memory bandwidth, populate channels evenly across every installed processor. The PC4-2400T-R label encodes the memory generation, speed grade and module type. The 4DRX4 code describes how the module’s memory chips are organised; where you can, match it to the modules already fitted. Error-correcting code catches and fixes single-bit errors as they happen, which matters on machines that run for months at a time. Load-reduced modules are the route to the largest memory totals a server supports, the usual choice for big virtualisation hosts. A module rated at 2666MHz runs at the lower of its rating and the speed the processor and memory population allow. Registered and load-reduced modules cannot share a server, so match the module type already fitted, and keep capacities and speeds consistent.

It is supplied certified refurbished: inspected, bench-tested and function-checked in Johannesburg before release.
