A-Tech 32GB DDR4 2400MHz ECC RDIMM 2Rx4 Server Memory

SKU CH-0JVR-JC7J4

32GB DDR4 2400MHz ECC registered server DIMM with CL17 latency and 1.2V operation

  • Capacity32GB
  • SpeedDDR4 2400 (PC4 19200)
  • CAS LatencyCL17
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredRegistered
  • 32 GB capacity handles heavy server workloads
  • DDR4 2400 MHz speed moves data fast
  • ECC RDIMM detects and corrects memory errors
  • Registered 2Rx4 design scales to high densities
  • 2 V operation keeps power draw low

Server Memory Upgrade

This 32GB DDR4 ECC RDIMM is built for servers and workstations that require registered memory with error correction. It operates at 2400MHz with CL17 latency and runs at the standard 1.20V voltage. The module uses Samsung chipset components in a 2Rx4 configuration.

Registered ECC Environments

The module fits systems that specifically support DDR4 RDIMM with ECC functionality. It will not work in desktop or laptop platforms that require unbuffered non-ECC memory. Buyers needing higher capacity per slot or faster speeds should look at other modules.

32GB Single Module Capacity

One module delivers 32GB of registered ECC memory for multi-socket servers handling virtualization or database workloads. The 2Rx4 organization provides density within standard power limits. Systems requiring larger total memory will need additional modules populated across available channels.

Preguntas sobre este artículo

My motherboard has 288-pin DDR4 slots — will this 32GB 2400MHz ECC RDIMM module fit and run at 1.2V?

Yes, the module uses the standard 288-pin DDR4 DIMM form factor and operates at the DDR4 standard voltage of 1.2V, so it fits any DDR4 288-pin slot electrically.

I already have Samsung M393A4K40BB1-CRC4Q sticks at CL17 — will this A-Tech replacement mix without timing conflicts?

This module matches the Samsung part at DDR4 2400MHz, CL17, 1.2V, 2Rx4 ECC registered, so timings and organisation are identical for mixed-channel operation.

After installing the 32GB ECC RDIMM, how can I confirm the server sees the full capacity and ECC is active?

Check the BIOS memory map or OS tools such as dmidecode on Linux or Task Manager on Windows; they should report 32GB per module with ECC type shown as Registered ECC.
