Good Afternoon

 

The specifications of the P51 are viewable here in the PSREF guides: https://psref.lenovo.com/Product/ThinkPad/ThinkPad_P51

 

In that documentation it states:

 

Memory
64GB max / 2400MHz DDR4, ECC or non-ECC (ECC function supported only on
Xeon processor), dual-channel capable, four DDR4 SO-DIMM sockets
* System clocks down for processors with lower memory controller

 

Hope this helps.

Hello,

 

As long as the memory has identical characteristics it should be compatible, however, without using an actual compatible part from Lenovo it is impossible to know for certain.  I would suggest purchasing the RAM from a reseller with a good return policy in case the memory is not compatible.
