System-specific DDR3 upgrade

This 4 GB DDR3 module is built for Gateway desktops DX4870-UB21P, DX4870-UB20P and DX4870-UR11P. It installs as a single 240-pin DIMM running at 1333 MHz with CL9 timing and 1.5 V operation. The kit targets owners of those models who want to add memory without compatibility guesswork.

Capacity and headroom

Each system accepts up to 16 GB across four sockets, so this 4 GB stick leaves three slots open for further expansion. It handles everyday multitasking and typical office workloads comfortably, while memory-intensive applications or large datasets will eventually require filling the remaining slots.

DDR3 1333 interface limits

The DDR3 1333 interface caps bandwidth at the PC3-10600 rate, so overall throughput cannot exceed that ceiling regardless of how many modules are installed. Builders needing higher memory speeds or a different DDR generation must choose a platform that supports those standards.

Questions about this item

Will this 4 GB DDR3 1333 module run at its rated speed in my Gateway Dx4870 with the existing memory?

The module is rated DDR3 1333 (PC3 10600) CL9 at 1.5 V. Your Gateway Dx4870 supports up to 16 GB across four sockets, so the new stick will operate at the platform's standard DDR3 1333 speed alongside any compatible modules already installed.

How can I verify the stick is detected at 4 GB and 1333 MHz after I install it?

Power on the desktop and open the BIOS or UEFI setup. The memory information screen should show the new 4 GB module running at 1333 MHz with timings of 9-9-9. You can also confirm the total capacity and speed in Windows Task Manager under the Performance tab.

What comes in the package and do I need any extra parts to install it?

The box contains one 4 GB 240-pin DDR3 DIMM. No additional brackets, cables or tools are required — simply insert the module into an empty DIMM slot on the motherboard.
