System-Specific DDR4 ECC Kit

This NEMIX RAM kit supplies 128 GB across eight 16 GB DDR4 3200 ECC UDIMM modules built for the SuperMicro R12SPD-A. Each stick runs at 1.2 V with CL22 latency and uses a 2Rx8 organisation. The unbuffered design targets server and workstation boards that accept non-registered ECC memory.

Verify Motherboard Slot Count And ECC Support

Before ordering confirm that your R12SPD-A has eight free 288-pin DDR4 slots and that its BIOS enables ECC on unbuffered DIMMs. The kit requires all eight sockets to reach the full 128 GB capacity. Mixed-rank or mixed-voltage populations can prevent the system from posting.

Matched Eight-Module Kit Simplifies Population

The package delivers eight factory-matched 16 GB modules so you can fill every channel in a single step. No additional cables, software licences or heat spreaders are included. The matched set reduces the risk of timing mismatches that can cause instability in multi-DIMM server configurations.

Questions about this item

What comes inside the 8x16GB kit and do I need anything else to install it?

The box contains eight 16GB DDR4 3200 CL22 ECC UDIMM modules for a total of 128GB. No extra parts are required; the modules plug directly into the 288-pin slots on a compatible SuperMicro R12SPD-A board.

Why choose the 128GB 2Rx8 CL22 version over a lower-capacity kit?

This kit delivers 128GB across eight dual-rank 16GB sticks running at 3200MT/s with CL22 timing at 1.2V, maximising the R12SPD-A's supported memory density while keeping ECC error correction active.

What does the 3200 CL22 rating mean once the memory is running in the server?

The modules operate at 3200MT/s (PC4-25600) with a CAS latency of 22 cycles at 1.2V, providing 128GB of ECC-protected bandwidth for the SuperMicro R12SPD-A's memory controller.
