SAMSUNG M393A4G43AB3-CWE 32GB DDR4 3200MHz CL22 ECC Registered 288-pin server RAM

SKU CH-A46N-M48PX MPN M393A4G43AB3-CWE

32 GB DDR4 server memory module running at 3200 MHz with CL22 latency, ECC error correction and registered signal processing on a 288-pin RDIMM

  • Accessory categoryParts
  • 32 GB capacity fits large server workloads
  • DDR4-3200 speed moves data at 3200 MHz
  • ECC protection corrects single-bit errors automatically
  • Registered signal processing reduces electrical load on the bus
  • CL22 latency balances timing with stability

32GB DDR4 ECC Registered Server Memory

This single 32GB DDR4 module operates at 3200MHz with CL22 latency and runs at 1.20V. It uses a registered signal processing design and includes ECC error checking for data integrity in server environments. The module follows the 288-pin RDIMM form factor.

Registered ECC Limits on Consumer Platforms

Registered DIMMs with ECC require a motherboard and CPU that explicitly support registered signal processing and error correction. Most consumer desktop chipsets cannot initialise registered modules or utilise the ECC function. The module will not operate in systems that only accept unbuffered non-ECC memory.

Verify Motherboard and CPU Support Before Ordering

Check your server or workstation documentation for qualified RDIMM support at 3200MHz and maximum capacity per slot. Ensure the platform accepts registered ECC modules and can address a 32GB single-rank or dual-rank stick. Systems limited to unbuffered memory will not post with this module.

Questions about this item

Should I pick the single 32 GB module or combine multiple sticks for my server?

This module is a single 32 GB DDR4-3200 RDIMM. Add identical sticks to fill your board’s channels and reach the total capacity your workload needs.

What does the 3200 MHz rating deliver in a live server?

The module runs at 3200 MHz with CL22 latency, giving 25 600 MB/s peak bandwidth per stick for DDR4 workloads.

How does the 288-pin DDR4 interface limit real-world speed?

The 288-pin DDR4 interface caps this RDIMM at the rated 3200 MHz; the platform’s memory controller cannot push it beyond that data rate.
