64 GB DDR4 ECC RDIMM Server Module

This A-Tech 64 GB DDR4 2400 ECC RDIMM module is built for servers and workstations that require registered memory with error correction. It operates at DDR4 2400 MHz (PC4-19200) with a CAS latency of CL17 and a standard voltage of 1.2 V. The 288-pin DIMM uses a 2S2Rx4 quad-rank 3DS/TSV organisation to deliver high density in a single slot.

Suitable for DDR4 RDIMM Platforms Only

This module fits systems designed for DDR4 ECC Registered DIMMs and will not work in desktop or laptop computers that accept only unbuffered non-ECC memory. Buyers needing memory for consumer motherboards or SODIMM slots should look elsewhere.

Quad-Rank 3DS Density Decides Fit

The 2S2Rx4 (4Rx4) 3DS/TSV rank structure determines whether the server or workstation memory controller can address the full 64 GB capacity. Verify that your platform supports quad-rank 3DS registered modules before purchasing.

Questions about this item

Will the 288-pin DDR4 DIMM fit my server's registered memory slots?

This module uses the standard 288-pin DDR4 RDIMM form factor, so it fits any server or workstation slot wired for DDR4 ECC registered memory.

Do I need to populate specific channels for the 2S2Rx4 quad-rank 3DS module to initialise correctly?

Install the DIMM in the channel order shown in your system manual; the common mistake is placing a quad-rank 3DS module in a slot the platform expects a single- or dual-rank DIMM.

When should I expect to replace this 64 GB ECC RDIMM in a 24/7 server workload?

DDR4 server memory has no scheduled replacement interval; swap the module only if ECC correctable-error counts rise sharply or the system logs uncorrectable memory errors.
