Capacity and purpose

This kit provides 128GB of DDR4 system memory in a matched set of four 32GB modules. It is built for SuperMicro desktop and SuperWorkstation boards such as the MBD-C9Z590-CG where high capacity and validated compatibility are required.

Who it suits and who it does not

The unbuffered non-ECC design fits standard desktop DIMM slots on supported SuperMicro platforms. Systems that require registered or ECC memory, or boards limited to lower maximum module densities, cannot use this kit.

Build integration

Each module runs at 3200 MT/s with CL22 timings at 1.20V across the 288-pin interface. The dual-rank 2Rx8 organisation uses major OEM chips from Samsung Micron or Hynix. No heat spreaders are fitted so clearance is minimal. The kit frees all four slots for other expansion when the board supports the full 128GB population.

Questions about this item

My SuperMicro MBD-C9Z590-CG motherboard has four DIMM slots — does this 128 GB kit fill all of them?

Yes, the kit contains four 32 GB UDIMMs for a total of 128 GB, matching the four 288-pin slots on that board.

Will these 3200 MHz CL22 modules run at their rated speed if I keep slower DDR4 DIMMs installed?

The memory controller will drop all modules to the speed of the slowest DIMM, so mixing with slower DDR4 will reduce the 3200 MHz rating.

How can I confirm the kit is running at DDR4 3200 with CL22 timings after installation?

Check the memory frequency and CAS latency in the BIOS setup or with a tool such as CPU-Z; they should show 3200 MT/s and CL22 at 1.20 V.
