Server-grade 64GB DDR4 ECC RDIMM

This 64GB DDR4 3200 module delivers ECC registered memory for workstations and servers that require data integrity. It operates at PC4-25600 speed with CL22 latency and a 1.2V supply. The 2Rx4 organisation suits high-density configurations in compatible platforms.

JEDEC-compliant 288-pin registered design

The RDIMM form factor fits standard 288-pin DDR4 server slots and follows JEDEC specifications for reliable operation. Registered buffering reduces electrical load on the memory controller, while ECC corrects single-bit errors. Mixing with unbuffered modules is not supported by the platform.

Low-voltage operation without heat spreader

At 1.2V the module runs within standard DDR4 power limits, helping keep system thermals manageable in dense chassis. No integrated heat spreader is present, so airflow across the PCB handles cooling. Typical server airflow keeps temperatures in check without added acoustic load.

Questions sur cet article

What DDR4 standard and speed does this 64GB RDIMM use, and what bandwidth does that cap at?

It runs at DDR4 3200 (PC4-25600), so the theoretical peak bandwidth is 25600 MB/s per module.

What physical slot and pin count does this 288-pin RDIMM need to fit in a server board?

It requires a DDR4 288-pin RDIMM slot; the module is 2Rx4 registered with ECC and has no heat spreader.

How is this ECC registered RDIMM installed, and what common mistake should be avoided?

Align the notch with the DDR4 288-pin key, press firmly until the latches click, and do not mix it with unbuffered UDIMMs.
