One can mis-match memory size, but it will defeat memory interleaving, if the chipset supports it.

Characteristics of The SODIM RAM Module in BANK 2:
Total Width: 64 bits
Data Width: 64 bits
Size: 8192 MB
Form Factor: SODIMM
Type: DDR3
Type Detail: Synchronous
Speed: 1600 MT/s
Manufacturer: Samsung

I had a spare SODIM module:
Total Width: 64 bits
Data Width: 64 bits
Size: 4096 MB
Form Factor: Chip
Type: DDR3
Type Detail: Synchronous
Speed: 1600 MT/s
Manufacturer: Elpida

It has the same characteristics as the original SODIM. I do get an performance increace with it. Of course it would be better to have two modules of the same size.
But one should never let the best be the enemy of the good.

I am satisfied with the increase I could get without bying new RAM.

Yes, satisfied with second best is your prerogative. And not a bad choice if one already has the memory.

By the tone of the OP, they didn't have memory laying around; let alone coincidentally being the right type of memory.

But it's a good guess." - ohnonot

And I would be remiss if I didn't suggest the best option.

Overkill. It wasn't suggested the best was the only acceptable option.

I guess it comes from being mostly a hardware guy. Building kit computers in the '70s. Piggybacking ram and adding the logic chips to get more than 3k memory on my Vic 20... I loved this stuff. And then computers got to advanced for the average garage hacker like me to keep up with. Sad.

So, I can't help but 'shoot for the moon' where hardware's concerned. But that's just me.

The speed increase for reading/writing to both memory sticks simultaneously is a most noticeable performance improvement; and IMHO well worth the extra monetary cost.

@eight.bit.al You advised: "You don't have to match brand, but it'd always better". If money is no factor at all, you might be right. But money is a factor.

Do you know the theorethical performance difference between 2X6 GB RAM and 4+8 GB RAM? Do you think, you can you in everyday work notice the difference? If I someday buy a new 8 GB Sodim, I will perform benchmark test and share the result.
I predict the difference will be negligible and not noticable when using the pc.

So, adding a 4 GB module instead instead of buing an 8 GB, is not only a good choice, it is a very good choice.
It is not only ths Thinkpad that coyuld benefit from shopping...

It is allways SAFER to use memmory of same brand and specs. That is the main difference...
