Compatible Server Memory Kit

This 256GB kit contains four 64GB DDR4 3200 registered DIMMs built for Supermicro SuperServer 510P-M and 510P-MR systems. ECC error correction and registered buffering protect data integrity in multi-socket workloads. Modules run at 1.2V with CL22 latency and a 4Rx4 organisation. The 288-pin RDIMM form factor matches the server memory slots exactly.

Suited For Capacity-Focused Upgrades

Administrators expanding memory in the named Supermicro platforms will gain 256GB in a single validated kit. Buyers needing non-ECC unbuffered modules for consumer boards cannot use this product. Systems limited to lower densities or different pin counts should look elsewhere. Workloads requiring speeds above 3200 MT/s are not addressed by this specification.

Deciding Specification: 4Rx4 Registered ECC

The 4Rx4 registered ECC architecture determines whether the motherboard memory controller can address the full 256GB. Verify the platform qualification list before purchase. DDR4 3200 at 1.2V with CL22 timing is the only speed and voltage combination supplied.

Questions about this item

Will the 4Rx4 288-pin DDR4 3200 RDIMMs work alongside any existing 1Rx4 or 2Rx4 modules I keep in my Supermicro 510P-M?

The kit uses 4Rx4 organisation at 1.20 V. Mixing different rank counts per channel can limit the server to lower speeds or reduced capacity; populate all four slots with this matched 64 GB set for guaranteed DDR4 3200 operation.

How can I confirm the 256 GB kit is running at PC4-25600 CL22 with ECC active after installation?

Enter the BIOS on the SuperServer 510P-M or 510P-MR and verify the memory speed shows 3200 MT/s, CAS latency 22, voltage 1.20 V and ECC status enabled; the OS should then report 256 GB of registered ECC memory.

Does the MR25600-944K4 package include only the four 64 GB RDIMMs or are heat spreaders and tools supplied?

The box contains the four 288-pin DDR4 3200 CL22 4Rx4 1.20 V ECC RDIMMs and nothing else; no heat spreaders, no installation tools and no extra cables are included.
