Exact-Match DDR5 Server Memory Kit

This NEMIX RAM kit delivers 128 GB across four 32 GB DDR5 RDIMMs rated at 5600 MT/s (PC5-44800) with CL46 latency, 1.1 V operation and 2Rx8 registered ECC architecture. It is built as a precise upgrade for the Supermicro X14SDW-64CM-SP9F motherboard, matching the rank, voltage and timing the board's memory controller expects.

Suited For Verified Supermicro Platforms

The modules are validated for the X14SDW-64CM-SP9F, providing registered buffering and on-die ECC that maintain stability when every slot is populated. Builders using unbuffered UDIMMs, SODIMM form factors, non-ECC memory or kits with different capacities, speeds, voltages, latencies or rank organisations should select a different product.

288-Pin Registered DDR5 Form Factor

The 288-pin RDIMM layout is the single specification that decides fitment; only motherboards wired for registered DDR5 DIMMs at 5600 MT/s with 2Rx8 ranks and 1.1 V will recognise the full 128 GB capacity at rated performance.

Questions about this item

How can I confirm the 128GB kit runs at the rated 5600MHz CL46 after installation?

Enter the server BIOS or UEFI and verify the memory frequency reads 5600 MT/s with timings at CL46; the registered ECC design ensures the Supermicro X14SDW-64CM-SP9F recognises all four 32GB modules at full speed.

What does the kit contain and is anything else required for installation?

The box holds four 32GB 288-pin DDR5 RDIMMs totalling 128GB; no extra cables, brackets or heat spreaders are needed — just follow the motherboard manual for correct slot population.

Why choose this 128GB 4×32GB CL46 kit over other capacities?

This exact 4×32GB 2Rx8 registered ECC configuration matches the Supermicro X14SDW-64CM-SP9F memory-population rules, delivering the full 128GB at the board's native 5600MHz without down-clocking.
