Compatible ThinkPad upgrade

This 8 GB kit contains two 4 GB DDR3 SO-DIMMs built for the Lenovo ThinkPad T510i models 4313-xxx, 4314-xxx and NTF5GMD. It runs at 1066 MHz with CL7 latency and 1.5 V operation. The modules are unbuffered, non-ECC and use a 2Rx8 rank layout. They fit the two SO-DIMM sockets in those notebooks.

Kit contents and warranty

The package supplies two matched sticks so both slots can be populated at once. Computer Memory Solutions provides a limited lifetime warranty when the memory is purchased directly from them. Product appearance may vary from the reference image.

Verify your system first

Confirm your exact ThinkPad model number matches one of the three listed families before ordering. A 64-bit operating system is required to address the full 8 GB capacity. The board must accept DDR3 1066 SO-DIMMs at 1.5 V; other DDR generations will not fit or function.

Questions about this item

Will the 2Rx8 rank configuration require any future maintenance or replacement?

The 2Rx8 unbuffered modules have no moving parts or firmware, so no scheduled maintenance or replacement is needed under normal use.

What limit appears first when the CL7 1066 MHz kit runs continuously at full load?

The DDR3 1066 speed and CL7 timing set the bandwidth ceiling; sustained workloads will hit that throughput limit before voltage or thermal constraints.

How much heat and power do the 1.5 V sticks produce during all-day operation?

Each 4 GB module runs at 1.5 V without a heat spreader, so power draw and heat output stay low even during extended sessions.
