The memory technology is DDR4 SDRAM. The form factor is SO-DIMM 260-pin. The memory speed is 2133 MHZ.
So to add 8GB for example, you would look for a DIMM of 8GB SO-DIMM DDR4-2133. It may be easier to find a DIMM of DDR4-2400 which is fine to use.

How Much Is Memory For The Lenovo Thinkpad T470?

The cost of adding RAM to your laptop will depend on the amount of memory to decide to buy.
Most likely you will either purchase an 8GB or 16GB memory module.
I have added below a rough price for both these RAM modules. You will find its more expensive to buy directly from Lenovo, but make sure you select a reputable outlet when shopping around for price.

Crucial 16GB DDR4-2666 SODIMM  $68.99

I also wondered how much a storage upgrade would cost.  My Thinkpad T470 model has a 256GB SSD M.2 2280 PCIe NVMe storage drive, which is plenty for my uses, but how much would it cost to double that size to 500GB?

I was surprised a 500GB NVMe drive was only about $60 US dollars. I might have to think about making that purchase in the future.

  • The laptop takes a long time to boot
