Rank 4Rx4

  • 256GB total capacity from two 128GB modules
  • DDR4 2666 speed rated at PC4 21300
  • ECC Registered design detects and corrects data errors
  • 4Rx4 rank organisation for high-density server configurations
  • 288-pin DDR4 form factor fits standard server DIMM slots

256GB ECC Registered DDR4 Kit

This 256GB kit consists of two 128GB DDR4 2666 modules built for server platforms that require registered memory with error correction. The 288-pin DIMMs deliver PC4 21300 bandwidth and a 4Rx4 rank structure for high-density configurations. It targets administrators upgrading or populating enterprise systems that demand registered ECC reliability.

288-Pin DDR4 2666 Compatibility

Each module fits a standard 288-pin DDR4 slot and operates at the 2666 data rate without additional configuration on compatible motherboards. Registered buffering reduces electrical load on the memory controller, freeing headroom for large population counts across multiple channels. The kit is not suited for consumer desktop boards that lack registered DIMM support or ECC capability.

200,000 Configuration Validation

Black Diamond Memory validates every module against a library of over 200,000 server configurations before shipment. This testing reduces the risk of POST failures and compatibility tickets when deploying the kit into qualified platforms. No extra software, heatspreaders or lighting accessories are included in the package.

Preguntas sobre este artículo

What limits the sustained throughput of the 2666 MT/s DDR4 modules?

The DDR4 2666 (PC4 21300) specification sets the maximum data rate, so sustained throughput cannot exceed that speed.

How much heat do the two 128 GB registered DIMMs add to a server running all day?

Registered DDR4 2666 modules draw a few watts each, so the pair adds a small, steady heat load that normal server airflow handles.

What must the motherboard provide for these 288-pin DDR4 ECC registered sticks to work?

The board needs 288-pin DDR4 slots that support ECC and registered (buffered) memory, plus a memory controller able to address 4Rx4 ranks.
