Computer Memory Solutions CM5126412800DIMM 4GB DDR3 1600MHz CL11 1.5V

4GB DDR3 module for Gateway desktops

This 4GB DDR3 DIMM runs at 1600 MHz with CL11 timing and 1.5V operation. It is built specifically for Gateway SX2370 and SX2855 series desktops using 240-pin unbuffered non-ECC slots. The single-rank 1Rx8 design uses major-brand chips for reliable compatibility. Installation is a direct upgrade for the listed systems.

Capacity and headroom for everyday loads

A single 4GB stick handles web browsing, office applications and light multitasking without paging. The DDR3-1600 interface provides 12800 MB/s peak bandwidth, which matches the memory controller in these Gateway models. Systems with two or four slots can reach 8GB or 16GB total by adding identical modules. Performance drops when the installed capacity is exceeded and the OS swaps to storage.

Upgrade path from 2GB or factory configurations

This module replaces a 2GB stick or fills an empty slot in the supported Gateway desktops. The jump is worthwhile when the current memory limit forces frequent disk swaps during normal use. Buyers who need more than 16GB total or who require ECC error correction cannot use this kit. Systems outside the listed Gateway models are not guaranteed to work.
