8GB DDR3-1333 CL7 kit for ThinkPad X200

This 8GB kit contains two 4GB 204-pin DDR3 SO-DIMMs rated at 1333 MHz with CL7 timing. The modules run at 1.5 V, are unbuffered, non-ECC and use a 2Rx8 organisation. Computer Memory Solutions validates compatibility with the Lenovo ThinkPad X200 series.

Suitable for ThinkPad X200 owners

The kit fits ThinkPad X200 models 2024, 7454, 7455, 7457, 7458 and 7459 that accept standard DDR3 SO-DIMMs. It is not for systems requiring ECC or registered memory, nor for machines limited to lower-density 1Rx8 modules.

DDR3-1333 CL7 at 1.5 V

The decisive specification is the DDR3-1333 speed grade combined with CL7 latency at 1.5 V. The X200 memory controller must support this exact frequency, timing and voltage for the kit to operate correctly.

Questions about this item

Will the 204-pin DDR3 SODIMM modules fit the memory slots in a ThinkPad X200 7455?

Yes, the 204-pin DDR3 SODIMM form factor matches the X200 slots; the kit is listed as compatible with the 7455 model.

What is the correct way to seat both 4 GB sticks so the laptop recognises the full 8 GB?

Insert each module at an angle until the gold contacts disappear, then press down firmly until the side clips click; do both slots before closing the cover.

How can I verify the CL7 timing is active after installation?

Open the BIOS or a system-information tool and confirm the memory runs at 1333 MHz with 7-7-7 timings at 1.5 V.
