Samsung 16GB 2Rx8 DDR4-2400 RDIMM Server Memory

M393A2K43BB1-CRC4Q is a 16 GB, 2Rx8 registered module with ECC at 2400 MT/s and 1.2 V. The speed grade is the one older DDR4 servers were built around.

It fits systems whose memory is already DDR4-2400, where adding or replacing modules should keep the speed consistent so that nothing is slowed down.

Systems at this speed grade are widely deployed, which makes this module a practical spare to hold for planned maintenance or an unexpected failure. As a 2400 MT/s part, it is an obvious pick for keeping an older server on a uniform memory configuration, and refurbished or used units can bring the total cost down for that kind of maintenance job.

Refurbished units have a 1 year or 3 years warranty, and used units have 90 days.
