Mixing RAM timings and speed.

[julicarles9]

Hello everyone.

I'm here with a question that's been made quite often. I've been reading many topics but I couldn't find any direct answer to my situation.

I'd like to upgrade from 8G RAM to 16G RAM my Acer Aspire E5- 575G-562T.

This notebook is using a 1x8G Sk Hynix H5AN8G8NAFR TFC RAM (DDR4, 2133mhz, 15-15-15 at 1.2V).
As stated here https://www.skhynix.com/products.view.do?vseq=2173&cseq=73

There's no problem here. The thing is, where I live, there's no way to get that RAM or even something similar to it.

That's why I have no choice but to buy a 1x8G Crucial CT8G4SFD824A (DDR4, 2400mhz, 17-17-17 at 1.2V).
As stated here https://www.crucial.com/usa/en/ct8g4sfd824a

My question is, will this upgrade cause any serious issues or incompatibilities?
I know the speed of the 2400mhz Ram will be underclocked to 2133mhz. That's no problem.

Thanks for the help in advance.
Regards,
Juli.

In theory as long as the voltage is the same it should be OK - but that is not gospel.
The 2400 will slow down to 2133 and should have same 15 timings
