Lenovo ThinkPad Edge DDR3 SODIMM kit

This 8 GB kit supplies two 4 GB DDR3 SO-DIMMs rated at 1333 MHz with CL7 timing for the listed ThinkPad Edge models. It targets owners of E120, E125, E325, E420, E420S or E520 notebooks who need a matched pair to fill both slots. The modules are unbuffered, non-ECC and use a standard 204-pin layout.

Low-voltage unbuffered DDR3 operation

Each module runs at 1.5 V without a heat spreader, so power draw and heat output stay minimal inside the slim chassis. The CL7 7-7-7 timings keep latency low at the rated frequency. No active cooling is required and the sticks add no audible noise to the system.

Matched pair for dual-channel benefit

The two sticks are sold as a tested kit, allowing the memory controller to run in dual-channel mode where the platform supports it. Package contents are exactly the two SO-DIMMs; no tools, cables or software discs are included. Computer Memory Solutions provides a limited lifetime warranty when purchased directly from them.

Questions about this item

How do I install these two 4 GB SODIMM modules in a ThinkPad Edge E420?

Power off the laptop, remove the battery, unscrew the bottom memory cover, release the retaining clips, insert each module at an angle until the contacts are hidden, then press down until the clips lock.

Will these 1.5 V DDR3 1333 MHz sticks need any firmware updates or cleaning over time?

No firmware updates are required; the modules are passive components. Occasional dust removal from the slot with compressed air is the only maintenance.

What is the first limitation I will hit when running sustained workloads on this CL7 2Rx8 kit?

The 8 GB total capacity and 1333 MHz bandwidth are the primary limits; the modules have no heat spreader, so prolonged heavy use may cause thermal throttling.
