Gateway SX2855 4 GB DDR3 module

This 4 GB DDR3 DIMM is built for Gateway SX2855 and SX2850 desktops. It slots straight into the 240-pin sockets on those boards. Buyers who need ECC or registered memory should look elsewhere.

Thermals and power

Running at 1.5 V with no heat spreader, the stick stays cool inside the original chassis airflow. Unbuffered DDR3 at this voltage draws modest power and adds no audible noise.

Upgrade path

The system tops out at 16 GB across four sockets, so this module suits a step up from 2 GB or 4 GB. Builders wanting more than 16 GB total capacity cannot use this platform.

Questions about this item

How do I install the 240-pin DDR3 DIMM in the Gateway Sx2855-Ub12P, and what step is often missed?

Power off and unplug the desktop, open the case, align the notch on the 240-pin module with the slot key, press firmly until both side clips snap shut, then verify the firmware recognises the full 4 GB at 1333 MHz.

What maintenance or replacement will this 4 GB DDR3 module need over time?

No routine maintenance is required; keep interior dust-free for airflow. Replace only if memory diagnostics report errors or if the system is later upgraded beyond the 16 GB maximum across four sockets.

What limit appears first when this CL9 1.5 V module runs sustained workloads?

The 4 GB capacity ceiling is reached before thermal or bandwidth limits, causing the OS to swap once the working set exceeds the single module's address space.
