Samsung 64GB DDR4-2666 LRDIMM ECC 4DRX4 Server Memory

Here is a 64GB DDR4 load-reduced module from Samsung, rated at 2666MHz with 4DRX4 organisation (PC4-2666V-L).

Capacity per module decides how much headroom is left for later: larger modules keep slots free. The PC4-2666V-L 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. 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. 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. ECC corrects single-bit memory errors on the fly, which is why servers use it for long-running workloads. LRDIMMs buffer the data lines, so a server can hold more memory in total than with registered modules.

Our Johannesburg team inspects and bench-tests the part before it is released as certified refurbished.
