512GB DDR4 RDIMM kit for ThinkMate SuperMicro

This 512GB kit contains four 128GB DDR4 3200 registered DIMMs built for ThinkMate SuperMicro SuperServer 510P-WT, 510P-WTR and 110P-WTR platforms. Each module operates at 1.2V with CL22 latency and includes ECC error correction for data integrity in mission-critical workloads. The registered design reduces electrical load on the memory controller for stable operation at high density. IT professionals choose this kit to maximise memory capacity in compatible enterprise servers and workstations.

Registered ECC with 4Rx4 organisation

The single specification that determines fit is the 4Rx4 registered ECC RDIMM organisation running at DDR4 3200 PC4-25600. Your system must accept quad-rank registered modules with this exact rank configuration and voltage. Modules use major OEM Samsung, Micron or Hynix chips and carry part number MR25600-744K4. No heat spreaders are fitted, so airflow in the server chassis must be sufficient for bare DRAM packages. Verify the motherboard qualified-vendor list before purchase.

Four slots filled for 512GB total capacity

Populating all four slots delivers 512GB of addressable memory, suitable for large virtualisation clusters, in-memory databases and heavy compute nodes. The quad-rank density means each slot carries maximum DRAM, leaving no free slots for further expansion on a four-channel board. Workloads that exceed 512GB will require a platform with more memory channels or higher-capacity DIMMs. Systems limited to lower maximum memory per socket will not recognise the full kit.

Questions about this item

What does the CL22 latency mean for real-world server throughput?

CL22 indicates 22 clock cycles of CAS latency at the rated 3200 MT/s data rate, giving a fixed access delay that the memory controller accounts for in timing calculations.

How does the PC4-25600 rating limit usable bandwidth in a registered DIMM configuration?

PC4-25600 specifies the maximum theoretical transfer rate of 25600 MB/s per module; the registered buffer adds one cycle of command delay but does not change that ceiling.

What physical clearance and slot requirements apply to these 288-pin 4Rx4 modules?

Each 128 GB stick uses the standard 288-pin DDR4 RDIMM form factor and occupies one DIMM slot; four slots are needed for the full 512 GB kit.
