4 GB DDR3 SO-DIMM for ThinkPad T520

This 4 GB DDR3 1333 MHz SO-DIMM is built specifically for the Lenovo ThinkPad T520 models 4239, 4240, 4241, 4242 and 4243. It arrives as a single 204-pin unbuffered module rated at 1.5 V with CL7 timing. The kit adds one stick to the two available slots, helping the system reach its 8 GB maximum.

Ideal for owners upgrading a compatible ThinkPad

The module suits anyone restoring or expanding memory in the listed T520 variants where DDR3 SO-DIMM is required. It is not for laptops that only accept newer DDR generations, for desktops requiring full-size DIMMs, or for systems that mandate ECC or registered memory.

DDR3 1333 CL7 1.5 V specification

The decisive figure is the DDR3 1333 (PC3 10600) speed with CL7 latency at 1.5 V. Matching this exact speed, voltage and timing ensures the module will be recognised and run stably in the supported ThinkPad T520 models.

Soalan tentang produk ini

My ThinkPad T520 has two SO-DIMM slots — will this 4 GB module leave the second slot free for another stick?

Yes, the T520 provides two 204-pin slots and the system maximum is 8 GB, so adding this 4 GB module leaves one slot open for a second 4 GB stick.

If I keep my existing PC3-10600 DDR3-1333 module, will this CL7 1.5 V stick run at the same speed without manual timing changes?

The module is rated DDR3-1333 CL7 at 1.5 V; when paired with a CL9 1333 MHz stick the system will default to the slower CL9 timing at 1333 MHz automatically.

After installation, how can I confirm the new memory is recognised at 1333 MHz with the correct 2Rx8 organisation?

Open Task Manager or run CPU-Z — the memory tab should show 4 GB, DDR3, 1333 MHz, dual-rank (2Rx8) and 1.5 V operation.
