Hi, fellows!
I have a HP ProBook 640 G2 Notebook PC. It genuinely came with DDR4-2133 4GB SODIMM RAM. I upgraded it adding another 4GB stick. I thought it was 2133 type (I bought it second-hand) but finally I figured out it is DDR4-2400 type (using Speccy software). I read in the product specs that it may not support memory with frequency higher than 2133 type. Well, it's been now about a month I've been using my laptop with its 2 different RAM sticks (1x2133, 1x2400) and I haven't noticed any kind of trouble. Do you think I can go on like that or I MUST take the DDR4-2400 out of my ProBook asap?
Thanks a lot for your advice, guys!

It is ok to run both sticks now but the faster RAM will run at lower speed which is 2133MHz.
Regards.
