Is this motherboard compatible with the 9800x3d?

When making a determination of whether the CPU & Motherboard are compatible, look at the CPU Socket in specifications. Both have a AM5 socket, so it will work.

Can I use an Arctic Liquid Freezer III with this motherboard?

Yes, but the top M.2 heatsink will not fit. You will need to use a drive that has a heatsink already, like the Samsung ones, or get a 3rd party heatsink from Amazon. I used the 9100 Samsung one with the heatsink included, and it fits just fine.

The memory standard on newegg is listed as "DDR5 4400 / DDR5 4800", however I've seen other people saying they used 6000/6400. Which is correct? Would higher MTs be limited to the standard without overclocking? The processor I'm considering maxes out at 5600.

The memory standard listed is DDR5 4400 / DDR5 4800, but it supports up to 8200+ MT/s (OC) with Ryzen 9000 Series Processors, 8600+ MT/s (OC) with Ryzen 8000 Series Processors, and 8000+ MT/s (OC) with Ryzen 7000 Series Processors when overclocked. Higher MTs are possible through overclocking beyond the standard specifications.

how many hdd slots are there?

The motherboard has 4 SATA 6Gb/s ports for connecting HDDs.

If I am understanding correctly, if i use all m.2 slots I can only use one pci-e slot?

Yes and if you use 2 Gen 5 drives your GPU will run at 8x. I have a Crucial T7000 and two gen 4 drives all 2TB Windows boot very fast and my 4090 gets way better benchmark scores than it did with my 13900KS I am very happy with the 9950x. I most likely will not buy a 9950 X3D sinc I do more than game.

Is the ASUS ROG CROSSHAIR X870E HERO R easy to install?

It is no harder to install than any other motherboard. I like that the entire back is covered in a solid metal piece, which does make it heavy but very sturdy.

Does this motherboard have PCIE gen 5 M.2 slots?

Yes, this motherboard has three onboard PCIe 5.0 M.2 slots.

Are there any known BIOS issues with this motherboard?

Yes, there are significant concerns regarding BIOS stability issues, particularly with AI EXPO RAM.

Can I use ddr5 8000 on this board using 9950x3d?

Yes, the board supports DDR5 8000+ MT/s with Ryzen 7000 Series Processors, and the 9950x3d is part of the Ryzen 9000 Series, which supports even higher speeds, so you can use DDR5 8000 with this board using the 9950x3d.
