4 GB ECC DDR4-2400 server memory module for workstations and business PCs

  • ECC protection prevents data corruption in critical workloads
  • 2400 MHz DDR4 speed accelerates application responsiveness
  • 4 GB capacity expands workstation memory headroom
  • Single 4 GB module simplifies slot population
  • Low-power DDR4 design reduces system energy draw

4 GB ECC DDR4-2400 module for servers

This single 4 GB stick adds ECC-protected DDR4 memory to compatible HP platforms. It runs at 2400 MHz and is designed for business PCs, workstations and notebooks that require error-correcting RAM. The module targets IT teams upgrading or maintaining existing fleets.

Steady throughput under continuous workloads

ECC circuitry detects and corrects single-bit errors during extended compute sessions, preventing silent data corruption. Low-voltage DDR4 operation keeps thermals stable when the system runs at full load for long periods. The 2400 MHz rating sustains bandwidth without the voltage spikes seen in higher-speed kits.

Replaces failed or missing sticks in qualified HP

The part matches HP Smart Buy specification 1CA77AT, so it fits the same slots as the original memory. The upgrade is worth it when a workstation shows correctable memory errors or when a vacant slot limits multitasking headroom. Buyers who need larger capacities or faster speeds must verify platform support before purchasing.
