Dell 64GB DDR4-2933 ECC RDIMM Server Memory (W403Y)

At 64GB per module, the Dell W403Y helps a server reach large memory totals without filling every slot. That is useful for virtualization hosts and in-memory databases, where memory capacity sets how much the server can do.

The module is DDR4 and runs at 2933 MT/s. It is an RDIMM, so a register buffers the address and command signals between the memory controller and the DRAM. ECC is supported, so single-bit errors are found and corrected without stopping the system.

For the cleanest result, fill a server with matching W403Y modules, or at least keep every module at the same type and speed. When speeds differ, the server runs all memory at the speed of the slowest DIMM installed.

You can order the W403Y Refurbished, with 1 year or 3 years of warranty, or Used, with 90 days. Let us know your target memory total and how many modules that takes, and we will reply with pricing.
