Samsung 8GB DDR5 5600MHz Non-ECC Server Memory — M323R1GB4PB0-CWM

The Samsung M323R1GB4PB0-CWM is an 8GB DDR5 Non-ECC Unbuffered DIMM (UDIMM) operating at 5600MHz (PC5-44800) with CAS latency CL46 and 1.1V operating voltage. Built on Samsung's DDR5 x16 die architecture, this Single Rank module delivers next-generation DDR5 memory bandwidth for desktop, workstation, and entry-level computing platforms. As a Non-ECC module, it is designed for consumer and prosumer platforms that do not require error-correcting memory — offering maximum DDR5 speed compatibility at an accessible capacity point.

Frequently Asked Questions

Does this module support ECC error correction?

No — this is a Non-ECC module and does not provide error-correcting memory functionality. For ECC-protected deployments, use the M323R1GB4PB0-CWMOL (ECC Unbuffered) variant instead.

What does the CWM base qualification code indicate?

CWM is Samsung's base qualification code for this 8GB DDR5 5600MHz Non-ECC UDIMM PB0 series. Variants with extended suffixes represent specific OEM or regional qualifications — always verify against your platform's QVL before purchase.

Is this module compatible with DDR4 platforms?

No — DDR5 and DDR4 are not interchangeable. Always verify your platform's memory type requirement before ordering.

Whether you are upgrading a DDR5 desktop system, building an entry-level workstation, or expanding a Non-ECC DDR5 platform, the Samsung M323R1GB4PB0-CWM delivers the 8GB DDR5 5600MHz performance and Samsung manufacturing quality your system demands.
