Targeted ThinkPad DDR3 Upgrade

This single 4GB DDR3 SODIMM is built for specific Lenovo ThinkPad models including the W701, W701ds, X1, X121e, X130e, X220 and X220i. It addresses owners of those laptops who need a straightforward capacity increase without guessing at compatibility.

JEDEC Compliance and DIY Simplicity

The module meets JEDEC and RoHS standards, ensuring a warranty-safe installation that follows the original equipment specifications. No extra software or cables are included; the upgrade relies on the laptop's existing memory slot and the user's ability to perform a basic hardware swap.

1333MHz CL9 Speed Rating

The decisive specification is the DDR3 1333 (PC3-10600) CL9 timing at 1.5V, which must match the system's memory controller requirements. Buyers whose ThinkPad demands a different speed, voltage or ECC type cannot use this module.

Questions about this item

Will the 204-pin SODIMM slot on my ThinkPad X220 need any special tools or recurring maintenance after I install this module?

No special tools are required; the module simply clips into the 204-pin DDR3 slot. Once seated, it has no moving parts, no heat spreader, and no firmware to update, so no periodic maintenance is needed.

What is the first limit I will hit when running this CL9 1333 MHz module continuously at full load?

The module operates at the fixed JEDEC speed of 1333 MHz with CL9 latency and 1.5 V; sustained use cannot push it beyond those rated timing and voltage limits.

How much extra heat or noise does this unbuffered non-ECC stick add when the laptop runs all day?

It draws only 1.5 V with no heat spreader and no fan, so it adds negligible heat and zero acoustic noise to the system.
