Samsung 32GB DDR4-2666 LP ECC REG DIMM Memory Module

Overview

The Samsung M393A4K40BB2-CTD is a 32 GB DDR4 memory module designed specifically for server environments. Operating at 2666 mega transfers per second, it delivers a balance of high bandwidth and power efficiency with its 1.2-volt operation. This registered DIMM fits into a 288-pin RDIMM slot and includes error-correcting code (ECC) to maintain data integrity, making it a reliable choice for demanding workloads in data centers and enterprise servers.

Key features

• 32 GB capacity expands memory availability for intensive server applications and multitasking.
• DDR4 interface running at 2666 MT/s ensures fast and efficient data access for improved system responsiveness.
• Registered design stabilizes clock, command, and control signals when multiple modules operate on the same channel, enhancing system reliability.
• ECC with 8-bit parity detects and corrects single-bit errors, protecting critical data and preventing system crashes.
• Low 1.2-volt power consumption reduces overall energy use, supporting greener and cost-effective server operations.
• Supports both x4 and x8 memory organization and up to two ranks per module, allowing flexible configurations in dual DIMM per channel setups.
