Server Memory Kit

The NEMIX RAM MR44800-328K4 is a 128GB kit built from four 32GB DDR5 RDIMMs. It targets administrators upgrading the Supermicro X14SDW-40C-SP9F motherboard with registered ECC memory.

Registered ECC DDR5 5600

Each module runs at DDR5 5600 (PC5-44800) with a CL46 latency at 1.1V in a 2Rx8 configuration. The 288-pin registered design offloads the memory controller so all slots can be populated at rated speed while ECC corrects single-bit errors.

For Supermicro X14SDW Builds

This kit suits technicians who need the exact rank, voltage and timing the X14SDW-40C-SP9F expects for full-capacity operation. It is not for systems that require unbuffered UDIMMs, SODIMMs, non-ECC memory or a different DDR generation.

Questions about this item

What does the 5600 MT/s rating mean once the kit is installed in my Supermicro X14SDW-40C-SP9F?

The modules will run at DDR5-5600 (PC5-44800) with CL46 timing at 1.1 V, giving the full rated bandwidth the board's memory controller expects when all four slots are populated.

How does the 288-pin RDIMM interface limit what I can do with this memory?

The registered 288-pin DDR5 RDIMM form factor only fits server boards wired for RDIMMs; it will not work in UDIMM or SODIMM slots and the board must support 2Rx8 registered ECC population rules.

What physical clearance does the 4×32 GB kit need inside the chassis?

Each module is a standard-height 288-pin RDIMM without a heat spreader, so it fits the regular DIMM slot pitch on the X14SDW-40C-SP9F; verify the motherboard manual for any tall CPU-cooler overlap before installing all four sticks.
