Four green DDR4 UDIMM sticks without heat spreaders

NEMIX RAM

NEMIX RAM 64GB (4×16GB) DDR4 3200 ECC UDIMM CL22 memory upgrade

SKU CH-7RWD-2996Y

A 64GB kit of four 16GB DDR4 3200 ECC UDIMM modules with CL22 latency and 1.2V operation for Supermicro systems

  • Capacity64GB (4 x 16GB)
  • SpeedDDR4 3200 (PC4 25600)
  • ECCYes
  • Buffered/RegisteredUnbuffered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.20V
  • 64 GB kit expands server capacity
  • DDR4 3200 speed accelerates data throughput
  • ECC protection guards against data corruption
  • 2 V operation reduces power draw
  • Validated for Supermicro M12SWA-TF compatibility

Capacity and fit

This NEMIX RAM kit delivers 64 GB across four 16 GB DDR4 ECC UDIMM modules. It is built for Supermicro servers and workstations that require unbuffered error-correcting memory at 3200 MT/s.

Upgrade path

The kit replaces lower-capacity or non-ECC DDR4 UDIMMs in compatible Supermicro systems. The jump is worthwhile when workloads demand both higher total memory and the data-integrity protection that ECC provides.

Installation notes

Modules use the standard 288-pin DDR4 UDIMM form factor and operate at 1.2 V without heat spreaders. Installation follows the motherboard manual; the main risk is populating slots in an order the board does not support for 2Rx8 ranks.

Questions about this item

Will the 288-pin DDR4 UDIMM modules fit a SuperMicro M12SWA-TF motherboard?

Yes, the kit is built for that board and uses the standard 288-pin DDR4 UDIMM form factor.

Do I need to enable ECC in the BIOS after installing the 2Rx8 CL22 modules?

Install the four 16 GB sticks, then enter the BIOS and turn on ECC support so the 2Rx8 CL22 modules can correct errors.

When should I expect to replace the 1.2 V DDR4 3200 kit?

DDR4 memory rarely fails; replace only if a module develops errors or you upgrade to a platform that requires DDR5.
