different capacity memory upgrades

Hello, I want to ask about memory
I have 16GB DDR4 and 8GB DDR4 with the same speed, but different brands. Is it safe to combine it?
My device Lenovo T470 with 2 slot memory, support max 32GB.

About memory:
Team Group 16GB DDR4 2400 (CL 16-16-16-39)
Ramaxel 8GB DDR4 2400 ( CL i dont know) Standart Lenovo
Thanks before

apparently it is cl17

Technical Specifications for RMSA3260MB78HAF-2400

should be ok, they will just run at whatever is the lower speed.

Go here and choose whichever Thinkpad T-series laptop you have...

Lenovo ThinkPad T Series | Memory & SSD Upgrades | Crucial.com


Although either of those memory sticks "may" work... you really don't want to "guess" with RAM (memory).
Everything your computer does... it does through the RAM.

Get compatible RAM when upgrading. The Crucial site I linked will find compatible RAM for you.

thanks for the response and the information.
I already bought TeamGroup memory, because in my country it is quite difficult to find Crucial

I always recommend not to mix memory sticks, even with same speed and timings.
As SIW2 said, it may work but different sizes will allow only 8+8 G to work as dual channel. The last 8G will work on single channel.

thank you for the solution, so basically the specifications (speed, timing, size, and brands) must be the same?

Megahertz said:

Yes, that is the ideal.
Sometimes even same brand memory sticks use different chips.
That is why you find on the market "kits" with 2 or 4 memory sticks that are called "matched pairs".

Okay, nice tips thank you very much
