Samsung 16GB 2400MHz DDR4 PC4-19200 ECC Registered CL17 260-Pin DIMM 1.2V Single Rank x4 Memory Module – M393A2K40BB1-CRC4Q

Samsung 16GB DDR4 2400MHz ECC Registered Server Memory — M393A2K40BB1-CRC4Q

The Samsung M393A2K40BB1-CRC4Q is a 16GB DDR4 ECC Registered (RDIMM) server memory module operating at 2400MHz (PC4-19200) with CAS latency CL17 and 1.2V operating voltage. This Single Rank x4 module in a 260-Pin small form factor delivers reliable DDR4 memory bandwidth for compact server platforms and blade server environments that support this form factor. Error-Correcting Code (ECC) technology continuously detects and corrects single-bit memory errors in real time, ensuring data integrity in mission-critical environments.

Frequently Asked Questions

What is the difference between a 260-Pin and a 288-Pin DDR4 RDIMM?

260-Pin DDR4 RDIMMs are a compact form factor designed for blade servers and high-density server platforms. Standard server RDIMMs use a 288-Pin interface. The two form factors are not interchangeable — always verify your server platform”s DIMM form factor requirement before ordering.

What does the CRC4Q qualification suffix indicate?

Samsung uses qualification suffixes to denote OEM validation, regional certification, or specific server vendor testing. CRC4Q identifies this module”s exact qualification tier — always cross-reference with your server vendor”s memory compatibility or QVL list before purchase.

Is this module compatible with DDR5 servers?

No — DDR4 and DDR5 are not interchangeable. Always verify your server”s memory type and form factor requirements before ordering.

Whether you are expanding memory in a blade server infrastructure, deploying compact server platforms, or scaling virtualization capacity in high-density environments, the Samsung M393A2K40BB1-CRC4Q delivers the 16GB DDR4 2400MHz RDIMM reliability, ECC protection, and Samsung manufacturing quality your enterprise server environment demands.
