Capacity and form factor

This A-Tech module delivers 32GB of DDR5 server memory in a 288-pin RDIMM form factor. It runs at 4800MHz with a CAS latency of 40 and operates at the standard 1.10V. The module uses a 1Rx4 rank configuration with ECC and registered buffering for data integrity.

Suited for IBM-Lenovo upgrades.

This module is a compatible replacement for IBM-Lenovo part numbers SM37B06933, 4X77A83148 and 03KH605. It suits administrators upgrading supported server or workstation platforms that require registered ECC DDR5. It will not work in desktop boards or laptops that accept only unbuffered non-ECC memory.

Registered ECC with 1Rx4 rank

The single specification that decides fit is the registered ECC RDIMM design combined with a 1Rx4 organisation. Your system must explicitly support DDR5 RDIMM modules with ECC and this rank structure. Verify the memory seating and channel guidelines in your system manual before installation.

Questions about this item

Can this 32GB DDR5-4800 ECC RDIMM 1Rx4 module be mixed with existing DDR5 4800 registered DIMMs in the same server?

Yes, this module uses the standard DDR5 4800 PC5-38400 speed and 1.10V voltage. Matching speed, voltage, rank (1Rx4) and registered ECC type is required for stable operation alongside other DDR5 RDIMMs.

How can I verify the module is running at DDR5 4800 with ECC active after installation?

Enter the system BIOS or use a hardware monitoring tool to confirm the memory operates at 4800 MT/s, shows CAS latency 40, reports 1.10V, and indicates ECC registered mode is enabled.

Does the package contain only the 288-pin DDR5 RDIMM or are any cables or brackets included?

The box contains the single 32GB 288-pin DDR5 RDIMM module only. No cables, brackets, heat spreader or additional accessories are supplied.
