Product overview

The Samsung M323R1GB4PB0-CWMOL is an 8GB DDR5 server memory module operating at 5600MHz with PC5-44800 bandwidth specification. This ECC Unbuffered DIMM (UDIMM) features CL46 timings, 1.1V operation, and single rank x16 organization in a standard 288-pin form factor. Designed for enterprise servers and high-performance workstations, it provides error correction capabilities essential for mission-critical applications where data integrity is paramount. Key specifications include 5600MT/s transfer rate enabling high throughput for virtualization, database processing, and in-memory computing workloads. The ECC functionality detects and corrects single-bit errors, ensuring system stability in 24/7 environments. Compatible with Intel and AMD platforms supporting DDR5 UDIMM, including recent Xeon and EPYC processors. This module supports on-die ECC for improved reliability and power efficiency at 1.1V, reducing operational costs in dense server deployments. Ideal for entry-level rack servers, tower systems, and scale-out clusters requiring cost-effective memory expansion without registered buffer overhead. The unbuffered design maintains compatibility with consumer-grade motherboards while delivering enterprise-grade error protection.

Frequently asked questions

What platforms support the M323R1GB4PB0-CWMOL module?

Compatible with DDR5-enabled Intel Xeon Scalable (Sapphire Rapids+), AMD EPYC 9004/9005 series processors, and workstation platforms including Lenovo ThinkStation, Dell Precision, HP Z-series. Requires BIOS supporting DDR5 UDIMM ECC unbuffered memory typically version 2023+ firmware.

Does this module support dual-channel configurations?

Yes, the 1Rx16 single rank design supports dual-channel interleaving providing 112GB/s aggregate bandwidth. Populate DIMM slots A1/B1 first per channel for optimal performance. Maximum capacity depends on motherboard supporting up to 16 DIMMs per socket.

What is the voltage and power consumption?

Operates at 1.1V DDR5 standard voltage with typical active power around 4-6W per module depending on workload. Includes DDR5 power management states reducing idle consumption to under 1W enabling energy-efficient dense memory configurations.

Is this module hot-swappable?

No, standard UDIMM memory requires system power-off for installation. Designed for initial population or maintenance windows. Some advanced server platforms support memory hot-add with specific BMC firmware but verify motherboard documentation.

What ECC capabilities does it provide?

Provides on-die single error correction, double error detection (SECDED) protecting against soft errors from cosmic rays and electrical noise. Corrects 1-bit errors in real-time while flagging uncorrectable multi-bit failures to system logs preventing silent data corruption.

Can it mix with non-ECC DDR5 memory?

No, mixing ECC and non-ECC modules causes system instability or forces non-ECC mode disabling error correction. All memory in each channel must match capacity, rank, and ECC type for proper operation and full performance.
