P51s upgrade RAM question

I try to upgrade my Thinkpad P51s' RAM. I have no idea what kind of RAM I can use. I don't know should I purchase 240 pins or 260 pins? Can anyone gives me some idea? Thanks

Re: P51s upgrade RAM question

Hi Bill,

Welcome to Lenovo Community! And happy to have you here.


Looking at the ThinkPad P51s Platform Specifications, 32GB max / 2400MHz DDR4, dual-channel capable, two DDR4 SO-DIMM sockets.

Any DDR4 memory with above similar specifications are expected to work and below are few OEM listed memory modules from Lewnovo for your system: (source)

  • 01AG708         4GB DDR4 2400 SoDIMM
  • 01AG709         4GB DDR4 2400 SoDIMM
  • 01AG710         8GB DDR4 2400 SoDIMM
  • 01AG711         8GB DDR4 2400 SoDIMM
  • 01AG714        16GB DDR4 2400 SoDIMM
  • 01AG713        16GB DDR4 2400 SoDIMM 

I hope the above information helped you.

Re: P51s upgrade RAM question

Just go to legitimate 3rd-party memory manufacturer site, and search for Lenovo Thinkpad P51s.  They know what exact memory is compatible with that machine.


Here is the page from Crucial Memory, for the P51s.
