First thing first: everything is working fine after I turned on the computer. It was a brand new build with no operating system installed yet, so that's normal.

After I started up for the very first time, my screen showed this message: "AMI BIOS welcome CPU installed, enter setup for configuration. CPU fan speed detection error, press F1 to enter setup."

I think the PC can't see the fan because I only connected one cable from the controller header of the case to the pump slot on the mainboard. Do I just plug it in like that? Or do I need to change something else?

In my BIOS menu, there is a setting called "ASMedia Storage Controller." What does this mean? Is it safe to turn this off? It looks like a SATA controller, but do I really need to keep it on?

I also plugged the fan controller cable from the case into a specific slot labeled "CHA_FAN5" on the motherboard. Does it matter which one I use? Should I put it in a different slot instead?

Now here is a big problem: after turning on and rebooting, my PC has been stuck for code 99 for several minutes. If it can't get running, do I have to reset the BIOS, clear the CMOS, and change voltage settings manually for the EXPO profile? The motherboard supports this feature, and the RAM also supports it, but why isn't it working? What should I do?

Hey Ram, I need your Corsair Vengeance 32GB DDR5 kit because it's stuck. Can you tell me where the RAM slots are plugged into my board and if you've already checked those pins? My PC won't turn on at all after a restart, so maybe I have to clear the BIOS settings like resetting it. Also, in there, can you show me what version of the BIOS is currently installed?

A2 and B2 tools are needed here. Clearing CMOS will erase all BIOS settings and custom profiles, I think. I'm curious if it wipes everything. But I can share my current BIOS version in this thread anyway. I won't try to upgrade to beta just now.

Here is the Corsair RAM kit from Intel that uses an XMP setting. You can find it at this link: https://www.corsair.com/us/en/p/mem...-e...m2b6000z28

Plug the pump into the AIO_pump header. Run your fans from the radiator fan and CPU cooler headers. Asmedia has built-in SATA ports, but if you turn those off, you can't use any 2.5" or 3.5" drives anymore.

I got two wires that came along with my new radiator. One has just one plug, and the other has several plugs. I didn't know which one to use so I picked the single one. Does this matter? Is what happened in the video actually a real issue?

I need some help setting my RAM timing settings by hand. Do you have a few simple tips, just to set up an XMP on my AM5 board?

Your processor is set to handle up to 5600MHz when you have two pieces of RAM. If your RAM is rated at 6000MHz and the BIOS tries to push that speed, it could cause problems for the CPU. Check if your BIOS has a lower XMP setting or go straight down to 5600. Even with manual tweaks, maybe it just sticks to 5600 instead of hitting 6000.

Should I connect a CPU fan directly to my power supply? Should I use a water cooling loop for my graphics card instead of air cooling? And what exactly does the VRM stand for?

Yeah I saw that a few minutes ago on the webpage for the 9800X3D its rated for 5600 DDR5... In bios i can see the current speed is 6000. Where do i lower it to 5600 and if i do that, do i also have to edit other values?
