Capacity 32GB (2 x 16GB)

Rank 2Rx4

  • ECC protection prevents data corruption in critical workloads
  • Registered buffering reduces electrical load for stable multi-module operation
  • 32 GB total capacity across two 16 GB modules
  • DDR4 2933 speed delivers high throughput for server tasks
  • 2Rx4 dual-rank organisation maximises density per slot

32GB DDR4 2933 ECC Registered Kit

This Black Diamond Memory kit delivers 32GB across two 16GB modules built to the DDR4 2933 standard. Each stick uses 288-pin DDR4 SDRAM with ECC and registered buffering for data integrity in server environments. The 2Rx4 rank layout supports dense memory configurations on compatible platforms.

Suited For Registered DIMM Slots Only

These modules suit administrators upgrading or repairing servers that require registered ECC DDR4 memory at the 2933 MT/s data rate. They will not work in systems that accept only unbuffered UDIMMs, non-ECC memory, or a different DDR generation. Buyers needing higher frequencies, larger per-module capacities, or consumer-grade RAM should look elsewhere.

Registered ECC DDR4 at 2933 MT/s

The decisive specification is the registered ECC DDR4 interface running at 2933 MT/s (PC4 23400). A motherboard must explicitly support registered ECC DDR4 at this speed for the kit to function. Verify the platform memory-qualified list before purchase.

Questions about this item

Should I pick the 2 x 16GB kit or a single 32GB module?

This kit provides two 16GB modules for dual-channel operation on platforms that support it, giving 32GB total capacity.

What does the DDR4 2933 speed mean once installed in a server?

The modules run at 2933 MT/s (PC4 23400 bandwidth) when the platform memory controller is set to that speed; actual throughput depends on the CPU and motherboard configuration.

How does the 288-pin DDR4 registered ECC interface affect compatibility?

The 288-pin registered ECC DDR4 form factor fits only slots wired for registered DDR4; it will not work in unbuffered desktop or laptop sockets.
