RIMLANCE REU23400D8C2K64 64GB DDR4 ECC UDIMM

This RIMLANCE kit provides 64GB of DDR4 server memory in two 32GB unbuffered DIMMs. It runs at 2933MHz with CL21 latency and operates at 1.2V. The 2Rx8 ECC modules are built for data integrity in demanding environments.

Suited for ECC workstations and servers.

These modules suit servers and workstations that require Error Correcting Code for automatic single-bit error correction and double-bit error detection. They are not for consumer motherboards or laptops that lack ECC support in the chipset and BIOS.

288-pin DDR4 2933 CL21 2Rx8 ECC UDIMM spec decides

The single specification that decides compatibility is the 288-pin DDR4 2933MHz CL21 2Rx8 ECC unbuffered DIMM form factor. Your motherboard must explicitly support DDR4 ECC UDIMMs at this speed and rank configuration for the kit to function.

Questions about this item

Does the kit include anything other than the two 32 GB modules, or do I need to buy a heatsink or cable separately?

The package contains two 32 GB DDR4 UDIMM modules and nothing else; no heatsink, cable or additional hardware is required.

Should I pick the 2933 MHz CL21 2Rx8 version or a different speed and rank for my server?

Choose this 2933 MHz CL21 2Rx8 kit when your motherboard supports DDR4-2933 ECC UDIMM and you want the 64 GB capacity in a dual-channel pair.

What does the 2933 MHz rating actually deliver once the memory is installed in a working system?

The modules run at 2933 MT/s with CL21 timing at 1.2 V, giving the rated PC4-23400 bandwidth when the platform enables that speed.
