Purpose-built server memory

This NEMIX RAM kit delivers 1 TB of DDR5 ECC Registered memory in a 16-module configuration, each module rated at 64 GB. It targets administrators upgrading Supermicro X14QBH+ platforms that require fully populated 288-pin RDIMM slots running at the rated 6400 MT/s.

Verified fitment for one motherboard

The single specification that decides compatibility is the exact match to the Supermicro X14QBH+ motherboard memory population rules. The kit uses 4Rx4 Registered ECC modules at 1.1 V and CL52, the precise rank, voltage and timing the board's memory controller expects for full-capacity recognition at DDR5-6400.

Thermals, noise and power

Registered architecture offloads the memory controller so every slot runs fully populated at rated speed without additional active cooling. The modules operate at 1.1 V with no heat spreaders, relying on chassis airflow for thermal management while ECC corrects single-bit errors on the fly.

Questions about this item

What does the 6400 MT/s rating mean once the kit is installed in the Supermicro X14QBH+?

The memory controller will recognise the 16 modules at their rated 6400 MT/s speed and run the full 1 TB capacity without downclocking.

How does the DDR5 RDIMM interface and CL52 timing affect real-world throughput?

The registered DDR5 design buffers every command so all 16 slots stay stable at 6400 MT/s, while CL52 sets the minimum latency the controller waits for each read.

What physical slot and clearance requirements must the chassis meet for these 288-pin RDIMMs?

Each module needs a standard 288-pin DDR5 RDIMM socket; the kit contains no heat spreader so low-profile CPU coolers or tight DIMM spacing will not interfere.
