Gateway SX System Memory

This 4 GB kit contains two 2 GB DDR3 DIMMs built for the Gateway SX2803-582G50M and SX2803-G672G50Mi desktops. It is intended for owners of those systems who need to restore or expand memory capacity. Buyers with other platforms should verify compatibility before ordering.

240-Pin Unbuffered Build

Each module uses a 240-pin DDR3 interface without ECC or registered buffering, matching the factory specification for the listed Gateway models. The 1.5 V operating voltage and CL9 9-9-9 timings align with the PC3-10600 standard used by these machines. No heat spreader is fitted, so clearance inside compact chassis is unaffected.

DDR3-1333 Practical Limits

The DDR3-1333 interface caps bandwidth at the PC3-10600 rate, so performance will not scale beyond that ceiling regardless of other components. The Gateway SX2803 series supports a maximum of 8 GB across four slots, meaning this 4 GB kit leaves two slots free but cannot be exceeded. Systems requiring higher speeds or larger capacities need a different memory standard.

Questions about this item

What DDR3 standard and speed does this kit run at?

It runs at DDR3-1333 (PC3-10600) with CL9 9-9-9 timings at 1.5 V.

What physical slot and pin count does each module require?

Each 2 GB stick is a 240-pin unbuffered non-ECC DIMM that fits a standard desktop DDR3 slot.

How do I install the two sticks in the Gateway SX2803 and what mistake should I avoid?

Power off, open the case, insert both modules into matching-coloured slots until the latches click, then boot; the common error is seating only one side of a module.
