instance, a quality 'selectable upgrade page' from reputable reseller.

You could access information from this page without commitment.

While I'm not certain of your MB/Pro 13-inch build year model, I do

know the specs of my own 'Mid-2012 MB/Pro9.2 (non-retina) 13-inch

with 2.5GHz dual core' that I'd upgraded RAM to 16GB (8GBx2 chips)

{..Detailed output include optional upgrades; depending on build..}

That's easily used as reference. ~Results my example, here in this link:

So this link could take you very close; each section has detail entry-points.

Other handy info could be everymac.com (lookup) & free Mactracker.ca App.

Good luck & happy trails!🌤🎣

2012 is a breakpoint between MBPs that are easily upgraded and those that cannot upgraded. So we need more information.

Answering depends on the exact sub-model as shown when you do "about this Mac..." from your Apple menu:

This from High Sierra; Not sure the "About" window look like that in OS 10.15 but the sub-model is always the part with a date. Sure sure to include any modifiers—Early, Mid, or Late— that are present, and if it shows "Retina."

The more info we have the better the effectiveness of the responses
