A-Tech 16GB DDR4 3200 ECC UDIMM 1Rx8 Server RAM

SKU CH-7G6W-07KDD

16 GB DDR4 3200 ECC UDIMM with CL22 latency and 1.2 V operation for server workloads

  • Total capacity16 GB
  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMicron Chipset
  • CAS latencyCL22
  • Rated voltage1.2 V
  • Buffer typeUnbuffered
  • 16 GB capacity expands server memory for heavier workloads
  • DDR4 3200 MHz speed accelerates data transfer rates
  • ECC unbuffered design detects and corrects memory errors
  • 2 V operation matches standard DDR4 voltage requirements
  • 288-pin DIMM form factor fits compatible server slots

Capacity and purpose

This 16GB DDR4 ECC UDIMM module runs at 3200MHz with CL22 latency and 1.20V operation. It is built as a compatible replacement for Micron MTA9ASF2G72AZ-3G2B1 and MTA9ASF2G72AZ-3G2F1 parts in server and workstation systems.

Who this fits

The module suits administrators upgrading or repairing platforms that accept unbuffered DDR4 ECC memory in a 288-pin DIMM form factor. Builders who need registered or load-reduced DIMMs, or systems limited to lower DDR4 speeds, should look at something else.

Deciding specification

The critical detail is the unbuffered ECC design with a single-rank 1Rx8 organisation on Micron chipset. Verify that your motherboard and CPU support unbuffered ECC UDIMMs before ordering.

Questions about this item

What DDR4 standard and peak transfer rate does the PC4-25600 rating on this 16GB ECC UDIMM represent?

PC4-25600 denotes DDR4 3200 with a 25600 MB/s peak transfer rate on the 288-pin interface.

Which physical slot and pin count does this 1Rx8 16GB module require on the motherboard?

It fits a standard DDR4 UDIMM slot with 288 pins; the spec also lists a 262-pin form factor reference for the module itself.

What BIOS setting or installation step is commonly missed when adding this ECC unbuffered stick to a server board?

Enable ECC in the BIOS after seating the module firmly until the retention clips click; the board will not use error correction otherwise.
