Micron DDR5-5600 ECC RDIMM Spec and Price in Canada

DDR51x64GBRDIMM16.43 ns true latency

Micron's MTC40F2046S1RC56BD1 is the 64GB DDR5-5600 registered module, 2Rx4 ranks (EC8) at CL46 and 1.1V, with the MTC20F2085S1RC56BD2R a 32GB 2Rx8 sibling of the same 5600 line — the RDIMM grade aftermarket sellers document as their compatibility target. Micron is one of the two DRAM manufacturers behind most branded server modules, so this line is the reference-profile option at the speed current EPYC and Xeon platforms boot, for servers that want the maker's own dies rather than a rebadge.

Tied 4th of 18 models in the Server RAM catalog on Speed — 5 models share this figure.

How much RAM you actually needHow to size memory from the pressure your machine is under now, why running short quietly costs speed, and when a matched pair beats one stick.RAM speed and latency, and when they matterWhat a kit's MT/s and CAS latency each measure, why true latency is the two together, and the machines where the numbers actually change anything.SO-DIMM vs DIMM: the memory a laptop takesWhy laptop memory is a different module from desktop memory, how DDR4 and DDR5 are keyed apart, and why some machines take no module at all.What is ECC memory, and when you need itWhat error-correcting memory actually catches, how registered and load-reduced modules differ from unbuffered ones, and why the platform decides.
