OK!! Testing DONE!!
I find ZERO issues, and this is why I always want to do videos in instances like this, so you know I am being true and honest!
I created 3 videos, however I did have to make some changes to the hardware mentioned. I had to use my trusty 920 CPU instead of 980X, because my 980X wasn't playing nicely with this board. I'm an extreme overclocker (Frozen motherboard, CPU, memory), and the last time I used my 980X is was -73C and pushed past 1.7V, and that's been done 100 times to it, so needless to say it's been through a tough life
Anyway, it wasn't playing nicely with my UD7, so I had to use my 920. And the 920 is an ES, so only memory multipliers are 6+8, so I could not test with 2000Mhz as I mentioned, but I did set 200 Bclk and x8 memory, so I tested at 1600 as you mentioned
I tested as we mentioned earlier, Marvell set to IDE for the flash, and that went just fine aside from the errors you mentioned before, but that's all in the videos. I tested rebooting, hard reboot, boot from full power down, ect, plenty of testing and the memory scanner never slowed down at all! I also tested with Intel in AHCI, and Marvell in IDE and HCI. I also tested quick boot on and off, and while thinking of that for you, I also tested control alt delete mid way through windows loading, and it reminded me of your comment about the memory scanner sometimes being skipped like with Quick boot. That happens often, depending on how you reboot (Even from windows can do it), and sometimes when you save/exit out of the BIOS it can happen, various times that happens but generally never on a cold bootup unless you have quick boot enabled
And I thought of one more thing while I did all this testing, that may help you with the memory scanner!! You know the 1, 2, 3 boot order, if you aren't sure it's in Advanced BIOS I believe and I show this in the video. At first I left it on defaults, but then I noticed it was like that during one of my visits to the BIOS, so I set my normal, 1 hard drive, 2, 3 disabled. And that's what I think might help you, as I've seen it help people in the past when USB devices weren't to blame for slow startups, sometimes that is. So set that to 1 - hard drive, 2 - disabled, 3 - disabled and see if it helps at all.
Since those videos are HUGE and my connection is TERRIBLE upload speed. I'll have to process them and remove the sound, and try to shave off some of the size in camtasia studio. Hopefully I can get them all down to about 15-20MB, and that will take me about maybe an hour or more to upload, not sure as I haven't uploaded anything over 1-2MB in a long time
Anyway they will be coming, unedited except for audio removal, and I'll probably resize them or change the codecs whichever will help me get them to a reasonable size. I could upload them as is, but that would take at least 7+ hours, and often when uploading my connection will drop, so I can only upload huge files like that to FTP servers where I can resume uploads, and I don't have access to one right now. If you do, and you want the unedited videos I'll upload them for you, you'll just have to get me FTP access somewhere. No worries though, I'm a very honest guy when it comes to things like this, so if you don't have a server or FTP account anywhere, you'll be able to tell even with my smaller edited videos that they haven't been edited to screw with them in anyway.
I had to use a old camera (5 MP Sony Cybershot DSC-P92), so the quality isn't going to be great, hopefully it's good enough for you to see everything was fine in all my testing! And the reason for the 3 videos is the memory stick is only 128MB in that camera!! Haha
I'll post the videos later today once I've got them done and uploaded, in the meantime try my tip above and see if it helps!
Haha, Damnit man! I just realized all three videos I had auto focus on, so they are all always trying to auto focus. Ohh well, they are uploading now, it's pretty decent video for this camera, but if you need me to redo them all without auto focus I can tonight.

Sorry, I also just realized that I had the board set to RAID before using AHCI, so AHCI BIOS is installed in those videos!
However, as I mentioned before that AHCI BIOS is not installed message is normal! Here, check out the video I posted for this world record a while back, it shows that same message too!

This is completely normally and it depends on what mode you are in, have used, what hard drives and CD drives are connected where, if you've cleared CMOS in-between, flashed BIOS, ect. Tons of things, it does not matter either way what that says, and if you need me to make it say not installed on this board in a new video let me know and I'll get-r-done when I get a chance.
