System-specific DDR3 SODIMM for Lenovo 3000 G550

This kit provides 8 GB of DDR3 memory in two 4 GB modules built for the Lenovo 3000 G550 series. It uses the 204-pin SO-DIMM form factor and runs at 1333 MHz with CL7 timing. The modules are unbuffered, non-ECC and operate at 1.5 V.

DDR3 1333 MHz speed ceiling and two-slot limit

The memory runs at the DDR3 1333 standard, so the system bus cannot use faster DDR3 grades. The laptop has only two SO-DIMM sockets, so this pair fills every available slot and leaves no room for further expansion.

8 GB total capacity with 64-bit OS requirement

The kit delivers 8 GB total, but the computer can address that amount only when a 64-bit operating system is installed. A 32-bit OS limits usable memory to 4 GB, making half the capacity inaccessible.

Questions about this item

Should I choose the 2×4 GB kit or a single 8 GB module for my Lenovo 3000 G550?

The 2×4 GB kit matches the notebook's two SO-DIMM sockets and lets the memory controller run in dual-channel mode, which the single-module alternative cannot do.

Will the CL7 timing at 1333 MHz actually lower latency in everyday use?

CL7 at 1333 MHz gives a lower cycle-time than the more common CL9 parts, so the memory controller waits fewer cycles per request, improving responsiveness in typical workloads.

What does the PC3-10600 (1333 MHz) rating limit on this 204-pin DDR3 SO-DIMM?

The PC3-10600 rating sets the maximum data rate at 1333 MT/s; the memory controller will not run these modules faster than that specification.
