Gateway Desktop DDR3 Kit

This 8 GB kit contains two 4 GB unbuffered DDR3 DIMMs built to PC3-10600 speed with CL9 timing. It is made for owners of Gateway desktops Sx2370-Ur10P, Sx2370-Ur30P and Sx2855-Ur11P who want a matched pair that the manufacturer guarantees will work in those systems.

Not for non-Gateway or laptop upgrades

Buyers whose motherboards require ECC, registered modules, or a different pin count cannot use this memory. The kit is also unsuitable for anyone needing a single 8 GB stick, a higher frequency than 1333 MHz, or a lower voltage than 1.5 V.

240-pin DDR3 1333 CL9 spec

The decisive specification is the 240-pin DDR3 interface running at 1333 MHz with 9-9-9 latency at 1.5 V. If the target desktop accepts PC3-10600 unbuffered non-ECC DIMMs, this kit will fit; if the board demands a different generation, pin layout or voltage, it will not.

Questions about this item

How do I install the 240-pin DDR3 1333 CL9 modules into my Gateway SX2855 desktop, and what step is often missed?

Power off and unplug the PC, open the case, align each module's notch with the slot key, press down firmly until both side clips click shut, then verify 8 GB appears in BIOS.

What maintenance or replacement will this 1.5 V unbuffered kit need over its lifetime?

No scheduled maintenance is required; if a module fails, replace the faulty 4 GB stick with another DDR3 1333 CL9 1.5 V DIMM to keep dual-channel performance.

What limit appears first when the 1Rx8 chips run sustained workloads on the Gateway SX2370?

The CL9 latency at 1333 MHz sets the bandwidth ceiling; sustained throughput cannot exceed the DDR3-10600 rating regardless of cooling.
