System-specific DDR4 upgrade

This 32 GB DDR4 3200 module is built for Supermicro desktop and workstation motherboards such as the MBD-C9Z590-CGW. It targets IT professionals and enthusiasts who need a single-stick capacity increase on validated platforms. The unbuffered non-ECC design matches the board's consumer-grade memory slots.

Practical limits of DDR4 UDIMM

DDR4 UDIMM tops out at 3200 MT/s in this configuration, so bandwidth is capped at PC4-25600. Unbuffered operation means the memory controller drives every rank directly, limiting total rank count per channel compared with registered DIMMs. The 2Rx8 organisation adds electrical load that can restrict maximum populated slots on some boards.

Deciding spec: 2Rx8 CL22 at 1.2 V

The 2Rx8 dual-rank layout with CL22 latency at 1.2 V determines whether the module works in a given Supermicro platform. Boards qualified for single-rank or lower-latency parts may not train this combination. Verify the motherboard's qualified-vendor list for 2Rx8 CL22 support before purchase.

Questions about this item

Should I choose this single 32GB module or a multi-stick kit?

This is a single 32GB stick; add a second identical module to run dual-channel on boards with four slots.

What does the 3200 MT/s rating deliver in a real desktop?

The module runs at 3200 MT/s with CL22 latency at 1.2V, matching the JEDEC standard for DDR4-3200.

How does the DDR4 UDIMM interface limit this upgrade?

The 288-pin unbuffered DDR4 interface caps transfer rate at PC4-25600 and requires a motherboard DDR4 slot.
