That makes sense thank you! @Turbof1 I actually already ordered the 3000Mhz before reading your message. I probably should have checked the specs of the motherboard, but I assumed that it supported the 3000Mhz ones since the sticks already in it had that in their specs. But, I did look at the price different and it was only $5, so I wouldn't have saved much anyway. Thank you for the information though! I'm sure it'll be enough as is, but I might look into the XMP thing as well, to use its full potential

@minibois Just to make sure, when you say 4gbs in a channel and 8gbs in a channel, is that put the 4gb ones in channel A, and the others ones in channel B? From the image, the last diagram points DIMMA1 DIMMA2 as the first two, does the A1 and A2 mean the same channel? Or is the 1s and 2s the channels? I think if I'm understanding you correctly, I should put 8gb 4gb 8gb 4gb in the slots, right? (or maybe 4gb 8gb 4gb 8gb)

Thank you everyone for your quick responses! From all your comments I decided to go with 2x8gb cards, at 3000MHz, for a total of 24gb, which should satisfy my needs for years. The only thing now is when they come, I'm not sure what the best placement is. I've read a bit about the channels and how different motherboards have colors to showcase them. I think from pictures I've seen, this one only has one color (black), so I'm not sure how to separate the channels and I also don't know what the best placement is. Should the 4gb ones be in one channel and the 8gb ones in the other? Or have each channel have a 4gb and an 8gb? I'll try to find some more detailed specs on the motherboard to see which slot belongs to what channel.

Hello! This is my first post at this forum. I am not very knowledgeable around hardware, so I need some help. I just got a used PC for a decent price. The only thing I want to upgrade on it is the memory. It comes with 8gb of RAM (2x 4gb DDR4-3000), and I wanted to have at least 16gb Should I get one more of 8gb? Can that work with the existing 2x 4gb? Can they be of different sizes or do I need to get two new 8gb or even 1 16gb? If I was to get a 16gb stick, could that work with the existing 2 of 4gb each to give me a total of 24gb? Finally, does the number after DDR4 matter? The two included are 3000 but online I've been seeing a bunch that say DDR4-2400 The mother board is the MSI Z270 PC Mate: https://us.msi.com/Motherboard/Z270-PC-MATE/Specification Like I said, I'm pretty new to this and I don't want to make a big purchase before I know for sure, so any help would be appreciated!
