Samsung - DDR5 - moduuli - 32GB - DIMM 288-PIN Low Profile - 4800 MHz / PC5-38400 - CL40 - rekisteröity - ECC (M321R4GA3BB6-CQK)

The Samsung M321R4GA3BB6-CQK is a 32GB DDR5 registered DIMM module with a 288-pin form factor and a 4800 MHz clock speed. Designed for server and PC use, this module features ECC capability with an additional 8-bit parity for error correction and a register to strengthen clock, command and control signals. It supports x4 and x8 device organization and can be configured with up to 2 ranks per DIMM and a 3DPC (three DIMMs per channel) setup.

Advantages

Registered (RDIMM) design improves signal integrity for multi-module server configurations, while ECC parity provides error detection and correction to enhance system reliability. The 4800 MHz DDR5 interface delivers higher bandwidth versus previous generations, and the 288-pin DIMM form factor ensures compatibility with standard DDR5 server motherboards. Low operating voltage (1.1 V) reduces power consumption compared with older memory types.

Suitable for

• Server platforms requiring registered ECC memory
• Workstations and PCs used for data-intensive tasks
• Multi-DIMM configurations and systems using 3DPC setups
• Environments prioritizing data integrity and uptime
