Compatible upgrade for Lenovo ThinkPad T520i 4239

This 8 GB DDR3 SO-DIMM is built to match the factory specifications of the Lenovo ThinkPad T520i 4239-xxx. It arrives as a single 204-pin module rated at PC3-10600 1333 MHz with CL9 timing and 1.5 V operation. The unbuffered, non-ECC design drops straight into one of the two available slots without configuration changes.

Steady throughput under sustained workloads

The module uses major-brand chips in a 2Rx8 organisation to maintain consistent bandwidth during long compile jobs, heavy browser sessions or virtual-machine paging. Rated CL9 9-9-9 latency and standard voltage keep error rates low when the system runs warm for hours. No heat spreader is fitted, so airflow from the notebook’s existing cooler passes directly over the DRAM.

Capacity ceiling decides fit

The platform supports a maximum of 16 GB across two sockets, so this 8 GB stick fills half the total headroom. Buyers who want more storage than 16 GB or need ECC protection for data-critical workloads cannot use this part.

商品問答

How much heat does the 1.5V DDR3 1333 module produce when running continuously?

Standard 1.5V DDR3 SO-DIMMs generate modest heat; this unbuffered 2Rx8 stick has no heat spreader, so airflow in the ThinkPad T520i chassis handles cooling.

Does my ThinkPad T520i 4239 need a specific BIOS version or second slot free to use this 8GB SODIMM?

The T520i 4239 has two 204-pin slots supporting up to 16GB total; this single 8GB module works in either slot with no special BIOS requirement.

Will this PC3-10600 CL9 stick run stably alongside an existing 4GB DDR3 1333 module already in my T520i?

Yes — both run at DDR3 1333; the system will operate in dual-channel mode at the slower module's timings if they differ.
