16 GB ECC UDIMM for DDR4 Servers

This 16 GB DDR4 module uses Samsung chips and runs at 2400 MHz with a CL17 latency. It is built as an unbuffered UDIMM for systems that accept ECC memory on a 288-pin desktop form factor.

Green PCB and 288-pin UDIMM layout

The green circuit board carries a 1Gx8 organisation and fits standard DDR4 UDIMM slots. Unbuffered registration means the module connects directly to the memory controller without an extra register chip.

Verify ECC support and DDR4 slot availability

Check that your motherboard or server board explicitly supports unbuffered ECC UDIMMs before ordering. The board must provide a free 288-pin DDR4 slot and run memory at the required PC4-19200 or PC4-21300 specification.

商品問答

What does the PC4-21300 rating on this DDR4 2400 module cap in practice?

The PC4-21300 label corresponds to a 2400 MHz data rate with CL17 timing, so bandwidth is limited to that specification.

What physical slot and pin count does the 288-pin UDIMM require?

It fits a standard desktop DDR4 DIMM slot with 288 contacts; the green PCB and 1Gx8 chip layout match the M391A2K43BB1-CRC form factor.

How is the unbuffered ECC stick installed, and what step do builders often miss?

Align the notch with the slot key, press firmly until both retention clips click, then enable ECC in the system BIOS or the module will run non-ECC.
