Lenovo P53 (20QQS46800) RAM upgrade advice

2020-01-21, 9:54 AM

Hi Lenovo comunity,

could you plese help me answering few questions?

My P53 configuration has one 32GB module installed (according to CPU-Z the module is Samsung M471A4G43MB1-CTD). Memory module has to be under thew keyboard, since no modules are under the bottom cover.

My questions are:

Do I need to assemble another module (M471A4G43MB1-CTD) under the keyboard to achieve dual chanel or it is sufficient to add it under the bottom cover?

What would happen if I add 2 x 16GB under the bottom cover? What should I expect? Single / dual / mixed mode?

Also M471A4G43MB1-CTD is not available in Czech Republic so does anybody tried mixing Samsung with other brand?
(I still could buy Samsung on amazon.de)

The only available 32 GB module (in CR) is Crucial CT32G4SFD8266  https://eu.crucial.com/eur/en/ct32g4sfd8266 which seems pretty similar to Samsung module in terms of specs. Should this configuration (Samsung + Crucial) work in dual chanel?

Thank you very much for help.

It must be installed under the keyboard to enable dual channel mode.

Device will probably not boot, as it won't be able to initialize 32+0+16+16 memory configuration.

Apart from Samsung, SK Hynix modules are officially supported:

  • FRU: 01AG871, SODIMM,32GB,DDR4,2666,HYNIX.
  • FRU: 5M30V06811, SODIMM,32GB, DDR4, 2666 ,Hynix.

Sadly, I don't know exact product numbers of these modules.

Sadly, I didn't had an opportunity to test 32GB modules, but 16GB modules were generally working fine. Samsung's M471A4G43MB1-CTD module can be easily found on eBay. There are many sellers from Europe, which have this module listed.

Thank you very much !
According to Crucial website compatibility check:

This part is 100% compatible with ThinkPad P53

Hard to say you can trust them.

I am aware of the fact that Samsung would be the best choice since I have Samsung module installed. 

I'll have to think about RAM upgrade if it is worth for me. 32 GB is sufficient for my work (Lightroom + Photoshop), but dual chanell for ocassional gaming is attractive.
