RDIMM ECC Registered Server Memory — the standard module type for Servers, Racks, Tower and Blade Servers. A register between the memory controller and the DRAM chips buffers address and command signals, letting a server address far more memory per channel than unbuffered UDIMM allows, with ECC correcting single-bit errors before they reach the OS.
This is the largest section of the catalogue: all modules spanning DDR5, DDR4, DDR3 and DDR2, from 2GB to 256GB per module and 1066MHz through 6400MHz. Every rank configuration is stocked — 1Rx8, 1Rx4, 2Rx8, 2Rx4, 4Rx4 and 8Rx4 — because rank matters as much as capacity on a populated server board.
RDIMM is not interchangeable with UDIMM or LRDIMM. A board that expects registered memory will not post with unbuffered, and load-reduced modules need explicit platform support. Filter by Technology Speed, Module Density and Rank to match your existing modules, or send us your server model and we'll confirm the fit.
Lifetime Warranty on every Module. Purchase orders, net terms and volume pricing for business, government and education buyers.
