You can mix without problems. There should only be the same amount of memory per channel. Everything runs with the specifications of the slower pair of bars. Otherwise, have a look at YouTube, where it is explained in detail.

Thanks for the info!

Most motherboards have 4 slots for RAM.When fitting these slots you should pay attention to the order and clocking.The rule is pair 1 - slots 1 and 3,pair 2 - slots 2 and 4.The clocking (frequency) is given after the type,so DDR4-3000,DIMM 288 means 3000 megatransfers per second.See also https://www.pc-magazin.de/ratgeber/ram-timing-latenz-bedeutung-3196625-15305.html and the video on https://praxistipps.chip.de/arbeitsspeicher-einbauen-darauf-muessen-sie-achten_39269.

Should work. It is important that the speed matches the RAMs, but the RAMs can also run slower. So they might run a little slower, but that's all.

Depends on the respective mainboard or CPU. For example, I have an ASRock Fatal1ty AB350 motherboard and a Ryzen 7 3700x CPU. My PC runs stable there with the working memory set to 3200 MHz. Alternatively, I would recommend doing a BIOS update. Most likely, this will fix the error.

XMP activated in BIOS?

You get what the configuration gives ;-) It fits, you can check other RAM according to the QVL to see if you like something: https://www.asrock.com/mb/AMD/B450M%20Pro4/#MemoryRR

DOA is 30 Days and Warranty is 30 Years. This is standard for RAM.

Unfortunately, we cannot say. The supplier himself is still waiting for a subsequent delivery from the manufacturer and for this reason he had to set the delivery date to unknown. As soon as something changes in this regard, we will post it here. Sorry.

Yes, the suggested ram speed is 3000mhz, but it will run fine at lower speeds. Some ram can also be overclocked to higher speeds depending on the motherboard capability, but then the manufacturer takes no responsibility for failure.

It is quite possible that G.Skill Aegis (2x, 8GB, DDR4-3000, DIMM 288) Manufacturer No. F4-3000C16D-16GISB could work. MSI only tested the Aegis series up to 2400MHz. G. Skill has developed the series up to 3000 MHz. MSI tested the Trident Z series up to 3200 MHz for the B450 Gaming Pro Carbon AC. It depends on whether OverClocking up to 3000 MHz is planned. When overclocking, it is also important to ensure good heat dissipation with the RAMs. Note the dimensions of the bars. Is a further expansion up to 32 GB total planned?

yes they are :-)

In order for the gamer PC to run well, it is important that the components are matched to each other. Since we are not experts, we rebuilt the computer according to the composition of https://www.hardwaredealz.com/. With a little help from a computer science apprentice, my son (12) was able to assemble the PC.
