Fits Lenovo Ideapad Z580 with 204-pin DDR3 slot

This module is built for owners of a Lenovo Ideapad Z580 who need a 4 GB DDR3 SO-DIMM running at 1600 MHz. It arrives as a single unbuffered stick with CL11 timing and 1.5 V operation.

Not for ECC or registered DDR3 systems

Buyers whose laptops demand ECC, registered modules, a different voltage, or a non-204-pin form factor cannot use this part. Systems limited to lower speeds or single-rank configurations should also look elsewhere.

Key spec is DDR3 1600 PC3-12800 204-pin SO-DIMM

The memory runs at DDR3 1600 labelled PC3-12800 in the 204-pin SO-DIMM format with CL11 11-11-11 timing at 1.5 V. Matching this exact speed, pin count, and voltage decides whether the upgrade will work.

Questions about this item

Does my Lenovo Ideapad Z580 need a free 204-pin DDR3 SO-DIMM slot to install this 4GB module?

Yes, the module is a single 204-pin DDR3 SO-DIMM stick, so one empty slot is required.

Will this PC3-12800 CL11 stick run stably alongside any existing DDR3 1600MHz memory already in the Z580?

The module operates at DDR3 1600 with 11-11-11 timing and 1.5V; matching speed, latency and voltage helps avoid down-clocking.

After fitting the CM5126412800SODRH, how can I confirm the Z580 recognises the full 4GB at 1600MHz?

Check the BIOS memory info or Windows Task Manager — both should show 4GB running at 1600MHz with CL11 timings.
