Product overview
This is the Samsung 16GB DDR4 3200MHz ECC RDIMM Memory Module, order code M393A2K40EB3-CWE. Registered, load-reduced and unbuffered modules are not interchangeable, and a board that accepts one will refuse to post on another. This module is ECC. Send the server model and we will check it against the supported-DIMM list before you order.
Quote requests are answered within 48 business hours, with availability confirmed before you raise a purchase order rather than after.
