32GB DDR4 3200 ECC UDIMM Server Memory

This 32GB DDR4 3200MHz ECC UDIMM module delivers error-correcting memory for server and workstation systems. It operates at 1.2V with CL22 latency and uses a 2Rx8 Samsung chipset configuration. The 288-pin DIMM is a compatible replacement for Samsung M391A4G43AB1-CWE and M391A4G43BB1-CWE part numbers.

Suits ECC UDIMM slots only.

This module fits systems that accept unbuffered ECC DDR4 DIMMs. It will not work in motherboards requiring registered (RDIMM) or load-reduced (LRDIMM) memory. Buyers needing non-ECC memory or registered modules for their platform should look at a different specification.

2Rx8 rank and 288-pin DDR4 interface decide fit

The 2Rx8 organization and 288-pin DDR4 interface are the critical specifications that determine compatibility with the memory controller and slot. Verify the system manual supports this exact rank structure and pin count before purchase.

商品問答

Which A-Tech DDR4 3200 ECC UDIMM capacity should I select?

This listing is for a single 32 GB module built with Samsung chips and a 2Rx8 organisation; choose it when your server or workstation needs one 32 GB stick.

What does the 3200 MHz rating mean once the module is installed?

The memory will run at up to 3200 MT/s at CL22 latency and 1.20 V, provided the platform supports that speed and the BIOS is set accordingly.

How does the DDR4 288-pin UDIMM interface limit performance in practice?

As an unbuffered ECC DIMM it connects directly to the memory controller without a register, so maximum capacity per channel is set by the CPU and motherboard rather than by the module itself.
