Gateway Sx2850/Sx2855 Memory Kit

This 8GB kit contains two 4GB DDR3 DIMMs built for Gateway Sx2850 and Sx2855 desktops. Modules run at 1333MHz with CL9 timings at 1.5V. They are unbuffered, non-ECC and use a 240-pin interface.

Suits owners of listed Gateway models.

Buyers upgrading a compatible Gateway desktop gain a matched pair backed by a lifetime warranty. Builders working on different motherboards or laptops cannot use these DIMMs because the pin layout and voltage are specific to the listed platforms.

240-pin DDR3 1333MHz CL9 specification

The memory uses a 240-pin DDR3 interface at 1333MHz with CL9 latency. This combination decides fit and function; any system requiring a different pin count, speed or voltage will not accept the modules.

Questions about this item

What motherboard slot type does this 240-pin DDR3 kit require?

The modules use a 240-pin DDR3 DIMM interface, so the motherboard must provide matching DDR3 slots.

If my Gateway desktop currently runs 1333 MHz memory, will this CL9 kit run at the same speed?

Yes, the kit is rated at DDR3 1333 (PC3 10600) with CL9 timing, matching the existing memory speed.

How can I confirm the system recognises the full 8 GB after installing both sticks?

Check the BIOS memory summary or Windows Task Manager — both should show 8 GB total across the two 4 GB modules.
