Subject: Can't get XMP to boot, long boot time

POST time varies depending upon your hardware. I know you don't have an X99 system, but they are well known for long POST times. Most have eight DRAM slots, each one must be checked for memory, and if the owner uses quad channel memory, that also slows down POST. Plus the X99 platform is based on Intel's enterprise chipset, which puts stability before a fast POST time. The X99 POST process is simply longer than on other systems, nothing can be done about that.
The fastest boards to POST I've seen are very simple models. The fastest system to POST I have is the simple ASRock N3150M, the Windows "BIOS time" shown in the Startup tab of Task Manager is under four seconds. A fast CPU and memory does not help with POST duration. POST time is only comparable on identical systems.
If you mean you set Fast boot to Ultra Fast, the Ultra Fast setting will only work if you installed Windows in UEFI booting mode. You apparently don't have a UEFI booting installation, since it is normal in that case to be put into the UEFI/BIOS UI when the Ultra Fast boot setting is used. That error is detected, and the UEFI wants you to fix that option.
The more memory you have, the longer POST will take. How many other drives are in the PC? Do you have any optical drives? HDDs and optical drives take much longer to wake up, the POST checks for drives happen at the end of the POST process for that reason. Some HDDs take longer to wake up than others. USB devices other than the keyboard and mouse also slow down POST.
POST codes on the Dr Debug display only indicate a problem if POST fails, and a POST code remains displayed. If you can get into the UEFI/BIOS or the OS boots, POST finished normally.
If the MRC Fast Boot option is disabled, that causes memory training, which increases POST time.
My ASRock Z270 Gaming K6 board with Samsung 960 EVO as the OS drive with Windows 10 installed in UEFI booting mode has a Windows BIOS time of eight seconds. I have no HDDs and no optical drives connected, and only use the Intel SATA ports. I don't even use any Fast Boot option. Check the number of programs in the Startup tab of Task Manager, they slow the actual boot time down.
Something related to your hardware must be slowing down the POST time.

I was playing around in the bios and saw the Xtreme bootup option and enabled it. Sadly on restart it only boots to the bios over and over again until I disable that option. I am watching the debugger for clues and looking at all the bios options but I can't find how to bring that post time down. Any ideas since you have one would be great, I would be forever in your debt. P.S. To reiterate the PC once booted up is great and my specs are below.
