Server Memory Kit

This 512GB kit contains two 256GB DDR4 3200 registered DIMMs built for enterprise servers. It targets administrators upgrading or populating multi-socket platforms that require error-correcting memory. The modules are not compatible with standard desktop or workstation boards that accept only unbuffered DIMMs. Buyers needing non-ECC memory for consumer systems must choose a different product type.

8Rx4 Rank Configuration

Each module uses an 8Rx4 organisation, which determines how the memory controller addresses the chips. This rank structure must match the server platform’s qualified-vendor list for the system to post and run at the rated speed. Platforms that only support lower rank counts per DIMM will not recognise these modules. Verify the server documentation before purchase.

Sustained Load Operation

The modules operate at 1.2V with a CAS latency of 22 while registered buffering reduces electrical load on the memory bus. This combination allows stable throughput during continuous workloads such as virtualisation, database caching or large-scale compute jobs. The registered design helps maintain signal integrity when all slots are populated under heavy, prolonged access patterns.

Questions about this item

What does the 512 GB capacity mean when installed in a server?

Two 256 GB registered DIMMs provide 512 GB of ECC-protected memory for multi-socket DDR4 platforms that support 8Rx4 modules.

What does the PC4-25600 rating limit in practice?

The DDR4 3200 interface caps data throughput at 25 600 MB/s per module; actual speed depends on the processor memory controller and populated slots.

What physical slot and clearance does the 288-pin RDIMM need?

Each module fits a standard 288-pin DDR4 RDIMM socket; verify chassis height clearance for the registered DIMM form factor.
