The issue is with the native 6 ports on the SATA controller. I have 1 DVD drive, 1 SSD, and 4 hard drives hooked up. When all are connected to the primary 6 ports (not the Marvell) one hard drive is always not detected in the BIOS (and obviously Windows). But if I simply unplug the drive that isn't being detected, plug it into the Marvell SATA port, it is detected. So I know the cable is good, drive is good, etc... but for some reason if all 6 native SATA ports are populated then one device will not be detected properly. Last thing is my system would POST and load into Windows (clean load) really fast with just the DVD drive and SSD hooked up. With all SATA populated, the board hangs for a while on the Gigabyte logo and also takes a lot longer to boot into Windows. I haven't timed it, the BIOS hang isn't too bad but booting to Windows seems a good while longer.
A reviewer on Newegg
left a comment with something similar.
I don't want to RMA. I think this is a BIOS problem or perhaps something even wrong with the chipset itself (which maybe means RMA?
) Anyway please pass this along to Gigabyte if you see this Sin and see if they/you can replicate the issue and see if there is a fix. I would be glad to troubleshoot with them and/or flash test BIOSes. Other than that I'm really enjoying this board with the BIOS and quality of the components.
See that is what they are trying to figure out, it also might depend on the drives themselves b/c they have been trying to reproduce the drive vanishing issue for a while and can't do it like Mandrix was reporting, so they are going to be more proactive about it now. It could be an Intel issue, as Intel did pull their iRST drivers off their site a few weeks ago and now has a new set there. It is also odd to me that this chipset has a TDP 2.6W lower than the Z77 PCH. So Z87 is 4.1W TDP while Z77 is 6.7W, Z87 has many more USB 3 and SATA III ports as well as many other newer features. They went to a smaller processing node as well, i think 32 or 22nm which would also account for reduced TDP or it is just some power saving features they have going. I have reported your issues tho

That is because F5 BETAs actually change uncore from 35x while F4 didn't.

You shouldn't have issues activating or installing windows, you should just able to install windows normally, But I am trying to see whether it is few types of drives that have issues or not.
Also the new Marvell controller they use on the UD5H shoudl be a the SE9230 and it should have very comparable performance to Intel's native, it uses two PCI-E lanes so if you use 1 or two SSDs you speed should be pretty damn high as it still has that huge bandwidth. It is basically a SE9182(opposed to SE9172) with 2 extra ports, and the SE9182 was actually not bad in tests, even its 4K speeds were high if not higher than Intel's ports.
