8GB DDR3 SODIMM for ThinkPad T520

This 8 GB DDR3 SODIMM module is built for Lenovo ThinkPad T520 models 4239, 4240, 4241, 4242 and 4243. It runs at 1333 MHz with CL9 timing and 1.5 V unbuffered operation. The single 204-pin stick uses a 2Rx8 rank layout and major-brand chips. It targets owners of these specific laptops who need a straightforward capacity increase.

Upgrading from 4 GB or smaller modules

The T520 ships with two SODIMM sockets and a factory ceiling of 8 GB total. Fitting this 8 GB stick replaces a 4 GB module and reaches the system maximum in one slot, leaving the second socket free. The jump is worthwhile when the current memory is a bottleneck for multitasking or 64-bit workloads. Buyers whose workload already fits in 4 GB will not see a speed gain from the extra capacity alone.

Tool-free slot access under a bottom cover

Installation requires removing the single memory-panel screw on the underside of the T520, then pressing the module into the SODIMM socket until the side clips latch. No thermal pad or heat spreader is involved. The most common issue is inserting the stick at the wrong angle so the notch does not align with the 204-pin key. If the laptop fails to POST, reseat the module firmly and verify the socket is clean.

この商品に関する質問

Does the 204-pin DDR3 SO-DIMM fit the memory slot of a Lenovo ThinkPad T520 4240?

Yes, the module is listed as compatible with the ThinkPad T520 4239, 4240, 4241, 4242 and 4243 models.

What is the correct way to seat the 204-pin SO-DIMM so the side clips engage?

Align the notch on the module with the key in the slot, insert at an angle until the gold contacts are fully hidden, then press down evenly until both retention clips snap into the side notches.

Will the 1.5 V DDR3 1333 module need a firmware update or voltage adjustment later?

No, it runs at the standard 1.5 V with CL9 9-9-9 timings and is unbuffered non-ECC, so no BIOS voltage change or firmware update is required.
