Server ECC RDIMM kit

This 256GB kit contains four 64GB DDR4 3200 registered DIMMs built for Supermicro H12SSL and H12SSW server boards. ECC and registered operation protect data integrity in multi-socket workloads. The modules run at 1.2V with CL22 latency and a 2Rx4 organisation. Standard desktop systems cannot use this memory.

Capacity and headroom

Four ranks per module give dense population for virtualization, database and compute nodes that need large address space. The 256GB total fills four slots on the validated Supermicro platforms. Workloads exceeding this capacity or requiring load-reduced DIMMs will need a different memory type.

Thermals and power

Bare modules without heat spreaders rely on chassis airflow for cooling in 1U and 2U server enclosures. Registered buffers and ECC logic add modest power draw at 1.2V, typical for DDR4 server DIMMs. Acoustic output depends entirely on system fan curves rather than the memory itself.

Spørsmål om denne varen

Will these 64 GB DDR4 3200 CL22 ECC registered modules work in the same server as my existing Supermicro H12SSL-NT memory?

They are qualified for the H12SSL-NT and other listed Supermicro boards; do not mix with unbuffered or load-reduced DIMMs.

How can I confirm the 256 GB kit is running at 3200 MT/s with ECC active after installation?

Check the BIOS memory information screen for 3200 MT/s speed and ECC enabled status.

Does the 4 × 64 GB kit include heat spreaders or mounting hardware, or must I buy them separately?

The modules have no heat spreaders and no extra hardware is included or required.
