Lenovo Thinkpad X220 12.5" Tablet Memory

This kit delivers 8GB of DDR3 SODIMM memory built specifically for the Lenovo Thinkpad X220 42984Bu 12.5" tablet. Two 4GB modules populate both slots to reach the system limit. Unbuffered, non-ECC operation matches the notebook architecture. It targets owners restoring or upgrading this exact model.

8GB Dual-Channel Capacity at CL7

The 2Rx8 organisation runs at 1333MHz with 7-7-7 timings and 1.5V voltage. Bandwidth suits everyday office workloads and light multitasking within the platform ceiling. Heavy virtualisation or large datasets will exhaust the 8GB ceiling quickly. No headroom exists for expansion beyond this kit.

204-Pin SODIMM Build Without Heat Spreaders

Major-brand chips sit on bare green PCBs sized for the X220 slot spacing. Low-profile modules clear the tight chassis without interference. Gold contacts mate cleanly with the 204-pin socket during installation. The kit ships as a matched pair for immediate dual-channel operation.

Questions about this item

Will the 204-pin DDR3 1333 MHz CL7 modules work if I keep the original 4 GB stick in my ThinkPad X220 42984Bu?

The X220 has two SO-DIMM slots; this 2 x 4 GB kit fills both, so the original stick must be removed. Mixed capacities and timings can prevent the system from booting.

How can I confirm the kit is running at CL7 7-7-7 timings after installation?

Open Task Manager → Performance → Memory or run CPU-Z; the SPD tab will show 1333 MHz and 7-7-7 latency when the modules are seated correctly.

Does the package include only the two SODIMM sticks or are tools and a heat spreader also supplied?

The box contains the two 4 GB DDR3 SODIMM modules only; no screwdriver, heat spreader or additional accessories are included.
