Question inserting 2 similar memory sticks

[kojaa]

Hello, i currently have this ram in my pc | Kingston HyperX Savage XMP 8GB (2x4GB) DDR4 3000MHz HX430C15SBK2/8 | but that one is not selling anywhere right now and i probably wont find the same one...
I found this one | Kingston 2 x 4GB DDR4 HyperX PREDATOR Black 3000MHz HX430C15PB3K2/8 |
will this affect performance of ram and is this even good to do , I've found threads about similar problems but most of the opinions and answers are mixed and most of them were using completely different sticks, this ones are similar to each other so if anyone has idea or any help it would be appreciated

Mixing RAM kits risks issues, sometimes it works sometimes it doesn’t. I have first had experience of mixing 2 exact same kits whereby the system was unable to boot. Underclocking and overvolting got the system to run but clearly not at rated speeds.

They should work. 2 different sets or ram seem to have pretty random results. Like you said, some people say it needs to be the same amount, speed or technology. I'm not 100% sure but in reality it really should work and you can always return it.

Again mixed answers, which i expected. The problem with returning ram @momowicket is that im buying pc parts in other country because its much cheaper and they have more warranty on their products so that wont work for me unfortunately. So i guess since i got 3 more years of warranty on the current kit i will try selling it and buy the 2x8 of the same one.

The answers are really unclear for this topic beause of all the random variables that contribute to it working or not, sorry I couldn't help. Something you could do is straight up buy the 16gb then try adding your 8gb if it works, great you have 24gb of ram, if not, sell it or keep it as a spare.
