Server Memory Kit

Black Diamond Memory BD128GX22400MQR96 delivers 256GB of DDR4 2400 ECC Registered memory across two 128GB modules. The 288-pin DIMMs operate at PC4 19200 speed with a 4Rx4 rank structure. This kit targets enterprise servers and workstations that require large-capacity, error-correcting registered memory for stable operation under sustained workloads.

Suited For And Limits

This memory suits administrators upgrading or populating servers that accept 128GB registered DIMMs at DDR4 2400. It is not for systems limited to unbuffered UDIMMs, platforms capped below 128GB per slot, or boards that cannot address 4Rx4 modules. Buyers who need higher frequencies, lower densities, or non-ECC memory should look at other product lines.

Registered ECC Benefit

The registered buffer reduces electrical load on the server memory controller, allowing the platform to support the full 256GB capacity across two slots. ECC circuitry detects and corrects single-bit errors, protecting data integrity in databases, virtualization hosts, and long-running compute tasks. These features replace standard unbuffered modules that lack error correction and cannot scale to this density.

この商品に関する質問

What motherboard slot and DDR generation does this 288-pin DDR4 2400 kit require?

A server motherboard with 288-pin DDR4 DIMM slots that support DDR4 2400 (PC4 19200) registered ECC memory.

Can I mix these 4Rx4 registered ECC modules with older unbuffered non-ECC DDR4 sticks in the same system?

No, registered ECC and unbuffered non-ECC memory use different signalling and cannot be mixed on the same platform.

How do I confirm the kit is running at DDR4 2400 with ECC active after installation?

Check the BIOS memory information or use a tool such as dmidecode to verify speed shows 2400 MT/s and ECC status reads enabled.
