Hi everyone,

I’ve recently upgraded my Lenovo Y720 RAM to 64GB. This laptop came with 16GB initially, but it’s very easy to upgrade it.

I was browsing Amazon and found that the Samsung 32GB DDR4 SODIMM modules were the cheapest available, so I went ahead and ordered 2 of them.

Upgrading it was as easy as removing the back cover:

We can see the 2x 8GB RAM modules installed in the laptop here:

And here they are removed:

The part number is M471A1K43CB1-CRC.

We will be replacing them with 2x 32GB Samsung DDR4 SODIMM modules with part number M471A4G43MB1-CTD:

Here we insert them in the laptop:

And it booted!

Here’s the Task Manager reporting the 64GB of RAM:

In CPU-Z:

While the RAM should go up to 2666Mhz, the laptop’s CPU only supports it up to 2400Mhz. It also seems that CPU-Z could not read the RAM details, as the SPD tab is empty:

The most important thing is that now my laptop has 64GB of RAM which will be plenty for a very long time.
