Four green circuit boards with black chips, no heat spreaders, 288-pin DDR4 UDIMM form factor

NEMIX RAM

NEMIX RAM 128GB (4x32GB) DDR4 3200 CL22 2Rx8 1.2V UDIMM SuperMicro SYS-530AD-I memory upgrade

SKU CH-1W14-2HW4G

A 128GB kit of four 32GB DDR4 3200 CL22 UDIMMs built for the SuperMicro SYS-530AD-I

  • Total capacity128 GB (4 × 32 GB)
  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL22
  • Buffer typeUnbuffered
  • Rated voltage1.2 V
  • 128 GB total capacity for heavy workloads
  • DDR4 3200 speed with CL22 latency
  • 2 V low-voltage operation saves power
  • 2Rx8 dual-rank modules maximise density
  • Validated for SuperMicro SYS-530AD-I workstations

Targeted upgrade for SuperMicro SYS-530AD-I

This 128 GB kit delivers four 32 GB DDR4 3200 modules built to the SuperMicro SYS-530AD-I specification. Unbuffered non-ECC UDIMMs run at 1.20 V with CL22 latency. The 2Rx8 organisation and 288-pin form factor match the workstation's memory slots directly.

Replaces lower-capacity DDR4 DIMMs

Swapping out smaller or slower DDR4 sticks for this kit raises total memory to 128 GB and sets the data rate to PC4-25600. The jump is worthwhile when workloads exceed the previous limit or when the original modules run below 3200 MT/s. Systems already populated with 3200 MT/s non-ECC UDIMMs gain capacity without a speed change.

Fits four UDIMM slots on the SuperMicro board

Four 288-pin slots are required, each accepting a 1.20 V unbuffered module. The kit frees no additional slots beyond the four it occupies. Builds needing ECC, registered DIMMs or a different DDR generation cannot use these modules.

Questions about this item

Does this kit use 288-pin UDIMM modules that fit a standard desktop DIMM slot?

Yes, the four 32 GB modules are 288-pin DDR4 UDIMMs designed for standard unbuffered desktop DIMM slots.

Do I need to enable XMP in the BIOS to reach 3200 MT/s, or will it run at that speed by default?

The modules are rated DDR4 3200 CL22 at 1.20 V; they will operate at that speed once installed and the BIOS is set to the rated profile.

Are the chips covered by a heat spreader, and will I ever need to replace a thermal pad?

The kit has no heat spreader, so there are no thermal pads to maintain or replace over time.
