Kingston Technology Corp. KVR16E11S8/4 4GB DDR3 1600 ECC Unbuffered server RAM

4 GB DDR3-1600 ECC module

This 4 GB DDR3 SDRAM module runs at 1600 MT/s (PC3-12800) with CL11 latency and 1.50 V operation. It uses a 240-pin unbuffered DIMM form factor and includes on-die ECC for single-bit error correction. The part is suited for entry-level servers and workstations that require data integrity without registered buffering.

Suited for basic ECC workloads

The module fits systems that accept unbuffered DDR3 ECC memory and need a low-cost capacity increase. It is not for platforms that require registered or load-reduced DIMMs, nor for builds that need higher densities per slot. Buyers who want more storage per module should look at larger-capacity kits.

Handles light multi-tasking and file serving

At 4 GB the kit comfortably runs a lightweight OS, a small database or a home file server with modest concurrent users. Headroom runs out when virtual machines, large datasets or heavy compilation jobs push memory pressure beyond the single-module limit.
