Certified Server Memory

This A-Tech module is a 32GB DDR4 2933MHz CL21 ECC Registered RDIMM built for Supermicro platforms. It uses Samsung chips and carries the MEM-DR432LC-ER29 qualification for direct compatibility. The single stick adds capacity to servers and workstations that require registered error-correcting memory. Installation is a standard 288-pin DIMM insertion.

Registered ECC Requirement

The decisive specification is the Registered ECC RDIMM design with 2Rx4 organisation. Systems that accept only unbuffered UDIMMs or non-ECC modules cannot use this stick. Buyers must confirm their motherboard or server documentation lists support for registered ECC DDR4 at 2933MHz before ordering. Voltage is 1.20V, matching the DDR4 standard.

Suited for Qualified Supermicro Builds

This module suits administrators expanding qualified Supermicro servers or replacing failed sticks in validated configurations. It is not for desktop PCs, laptops or consumer motherboards that lack registered ECC support. Builders needing unbuffered memory, higher speeds or larger single-module capacities should look elsewhere.

Questions about this item

What does 2933 MHz mean once this module is installed in a server?

The module runs at DDR4 2933 speed, delivering PC4-23400 bandwidth so the memory controller can move data at that rate when the platform supports it.

How does the 288-pin RDIMM interface limit what this memory can do?

The 288-pin RDIMM form factor fits registered DIMM slots and the registered buffer lets the memory controller address 2Rx4 ranks reliably at 1.20 V.

What physical space and slot type are needed to mount this 32 GB stick?

It requires a standard DDR4 288-pin RDIMM slot and the module height matches regular server DIMM clearance.
