System-specific DDR3 upgrade

This 8 GB kit uses two 4 GB unbuffered DIMMs rated at DDR3 1333 MHz with CL9 timing and 1.5 V operation. It is built for the Lenovo ThinkCentre M90P desktops listed in the compatibility table, including models 3269, 3282, 3394 and 3421 among others.

Replaces slower or smaller modules

The kit raises total memory toward the platform ceiling of 16 GB across four sockets, with a per-socket limit of 4 GB. Installing a matched pair enables dual-channel mode; a 32-bit operating system will not address the full capacity.

Fits standard 240-pin DDR3 slots

No heat spreader is fitted, so clearance inside compact M90P chassis is not an issue. The modules require a 64-bit OS to use all 8 GB and must be installed in pairs; they do not serve ECC or registered memory requirements.

Questions about this item

Does this 240-pin DDR3 DIMM kit fit the four memory slots in a Lenovo ThinkCentre M90P?

Yes, the two 4 GB modules are 240-pin DDR3 DIMMs designed for the four slots in the ThinkCentre M90P models listed, including 3269, 3282, 3394 and 3421.

What is the correct way to install the pair for dual-channel mode?

Insert both sticks into the same-coloured slot pair — usually slots 1 and 3 or 2 and 4 — so the memory controller sees a matched 2Rx8 pair at 1333 MHz.

Will the 8 GB kit need any firmware updates or battery changes over its lifetime?

No firmware or battery is involved; the modules are unbuffered non-ECC DDR3 at 1.5 V with a limited lifetime warranty from CMS, so they run until a stick fails or the system is retired.
