A-Tech 16GB DDR4 2400 ECC RDIMM 2Rx4 CL17 1.2V Server RAM

SKU CH-KVVE-336G3

16 GB DDR4 2400 ECC registered DIMM with 2Rx4 organisation, CL17 latency and 1.2 V operation

  • Capacity16GB
  • SpeedDDR4 2400 (PC4 19200)
  • CAS LatencyCL17
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredRegistered
  • ECC protection prevents data corruption in critical workloads
  • Registered design reduces electrical load for stable server operation
  • 16 GB capacity expands memory headroom for virtualization
  • DDR4 2400 speed delivers 19200 MT/s bandwidth
  • 2 V standard voltage lowers power draw per module

Product Identity

This 16 GB DDR4 2400 ECC RDIMM is built for servers and workstations that require registered memory with error correction. It replaces Samsung M393A2G40DB0-CRC, M393A2G40DB1-CRC and M393A2G40EB1-CRC modules in compatible systems. Buyers needing unbuffered UDIMMs or non-ECC memory for consumer desktops cannot use this module.

Installation Notes

The 288 pin DIMM fits standard DDR4 server slots and operates at the DDR4 standard voltage of 1.2 V. Because it is a registered dual rank 2Rx4 module, the platform memory controller must support registered ECC RDIMMs; installing it in a board that only accepts unbuffered memory will prevent the system from posting. Verify the qualified vendor list before purchase.

DDR4 Interface Limits

DDR4 2400 PC4 19200 sets the maximum transfer rate for this module and CL17 defines its baseline latency. Registered buffering adds one clock cycle of command delay compared with unbuffered memory, which is normal for the RDIMM standard. The memory controller and BIOS determine the final operating speed; if the platform caps memory at a lower data rate the module will downclock automatically.

Questions sur cet article

How can I confirm the 16GB DDR4 2400 module is running at CL17 after installation?

Check the memory timings in your server BIOS or use a tool like CPU-Z; the SPD table should show 2400 MT/s with a CAS latency of 17 at 1.20 V.

Does the single 288-pin RDIMM ship alone, or are extra brackets or cables included?

The box contains only the 1x 16GB ECC registered DIMM; no brackets, cables or additional hardware are supplied.

Should I choose the 2Rx4 version or look for a different rank for my Samsung M393A2G40DB1-CRC replacement?

Select the 2Rx4 module listed here; it matches the rank organisation of the Samsung M393A2G40DB1-CRC part you are replacing.
