CMS 2 GB DDR3 SODIMM for Lenovo 3000 G550

This 2 GB DDR3 SODIMM runs at 1066 MHz with CL7 timing and 1.5 V operation. It is built as an unbuffered 204-pin module using a 2Rx8 rank configuration. The part is validated for Lenovo 3000 G550 series laptops including part numbers 59-031837 and 59-034045.

Suits owners upgrading a compatible Lenovo 3000 G550

Buyers who need ECC or registered memory should look elsewhere. Systems limited to lower voltage modules cannot use this 1.5 V stick. Laptops with only one memory slot gain no further capacity from a second module.

Deciding spec: DDR3 1066 CL7 204-pin SODIMM

The module matches the PC3 8500 speed grade and CL7 latency required by the listed Lenovo models. A different speed, pin count, or voltage will not fit or will not post. Verify the laptop part number against the compatibility list before ordering.

Vragen over dit artikel

Will the 204-pin DDR3 SO-DIMM fit the Lenovo 3000 G550 memory slots?

Yes, the 204-pin DDR3 SO-DIMM matches the two SODIMM sockets in the Lenovo 3000 G550 series and installs directly without adapters.

How do I install the module and what step do people often miss?

Power off the laptop, remove the battery, open the memory cover, insert the stick at a 30-degree angle until the gold contacts disappear, then press down firmly until both side clips click — the click is the step many forget.

When will this memory need replacement or maintenance?

The module has no heat spreader and no moving parts, so it requires no routine maintenance; replace it only if a memory test reports errors or you upgrade to the 4 GB 32-bit or 8 GB 64-bit system maximum.
