16GB DDR4 3200 UDIMM for Supermicro X12STE-F

This 16 GB DDR4-3200 module is built for the Supermicro X12STE-F and X12STD-F motherboards. It uses a 288-pin unbuffered UDIMM form factor with 1Rx8 organisation. The non-ECC design matches the desktop-class memory controller on these boards.

DDR4-3200 speed and CL22 timing limits

The module runs at 3200 MT/s with a CAS latency of CL22 at 1.2 V. This is the standard JEDEC data rate for DDR4-3200; the memory controller will not exceed this speed without manual overclocking. Bandwidth is capped at the PC4-25600 rating.

Major OEM chips and no heat spreader

Chips come from Samsung, Micron or Hynix and are tested at the rated speed, timing and voltage. The module has no heat spreader, so it fits tight DIMM slots without clearance issues. The 288-pin edge connector keys only into DDR4 UDIMM sockets.

Questions about this item

Which capacity should I select for the Supermicro X12STE-F or X12STD-F?

The module is a single 16 GB DDR4 UDIMM; add one or more to match the board's supported population rules and total capacity limit.

What does the 3200 speed rating mean once installed in the motherboard?

The DIMM runs at DDR4 3200 with CL22 timing at 1.2 V, delivering the rated transfer rate the memory controller expects for this platform.

Does the 288-pin DDR4 interface limit the usable speed on these boards?

The 288-pin unbuffered non-ECC UDIMM matches the motherboard's native DDR4 3200 specification, so the full rated speed is supported without downclocking.
