I have been trying to keep my cool and focusing on researching the issue as much as I could so here's my experience so far (it's been a couple of days).Context
: I just spent the weekend setting up my new rig since I have decided to upgrade my original build from a mATX to ATX form factor.
First time doing something overkill like this so I was pretty excited!
This included new parts starting with the
- ASUS X99A-II motherboard
- Corsair Dominator Platinum 32GB (4 x 8GB) DDR4-2400 (model confirmed in ASUS' RAM compatibility PDF here)
- 2 x EVGA GTX 1080 FTW
- Phanteks ATX TG case in silver

I absolutely love how it turned out; however, my experience was unfortunately soured by the motherboard's POST time.Issue
: By long POST time, I don't think I'm being unreasonable that 2 to 3 minutes is very high for a system running SSDs.
It would then go into a black screen with a "_" flashing on the top left of the screen then cycle through multiple splash screens as well as hang on the Intel Rapid Storage post screen (I didn't have anything resembling this in my previous rig with the same SSDs and HDDs).Initial boot set-up
: I was running RAID 0 with the 2 x Samsung EVO 850s and RAID 1 with the 2 x WD Black Hard Drives.Troubleshooting
: With a 16GB SanDisk USB for Windows 8.1 Pro, I've tried the following:
Some notables I've read
- First waited for UEFI to pop-up and headed over to advanced boot options and set my respective SATA controller A to RAID for the SSDs.
- The WD Black hard drives were also connected to this SATA controller A at this time.
- Post time still very lengthy so I continue
- Disable XMP profiles since I flicked the physical switch on the motherboard
- I thought maybe the RAM was a bad batch and turned off XMP and continued
- Flashed UEFI and updated to latest version "X99-A II BIOS 0601"
- Only plugged in mouse and KB USB connections.
- Clean Installed Windows via 16GB SanDisk (not UEFI/2nd option in UEFI boot priority)
- I wanted to do this to see if it made any difference from UEFI.
- Clean Installed Windows via 16GB SanDisk (as UEFI option in UEFI boot override)
- The UEFI USB is the recommend way and fastest so I tried this option as well.
- Un-raided the RAID 0 array and reformatted the two SSDs via Ctrl+I Intel rapid storage splash screen
- Cleared the RAID and wanted to see if it would affect POST, it's tough to gauge at this point since I've booted up so many times; however, the feeling that I get is the ACHI > RAID is just more consistent so I decide to go with it.
- I separated the SSDs and HDDs to different SATA controllers--Manual stated 6 and onward did not support RAID (IIRC?) thus
- SATA Controller A for WD HDDs running in RAID 1 config
- SATA Controller B or C for 2 x Samsung 850 EVOs un-raided and wiped running ACHI
- After 10 - 20 shutdowns/boot-ups, I forgot at which specific point; however, my RAID 1 "degraded", but would pop up later on to "rebuild"
- Some users have even gone as far as disabling DRAM testing
in the UEFI, this doesn't seem to be a good idea IMO so I did not attempt this.
I've seen Raja on the ROG forums state that X99 platforms' ASUS mobos are slower due to memory checking and PCIe lanes...but I can't help think of my previous EVGA X99 Micro2 mobo which booted in seconds.
- Some have disabled CSM
, I have yet to try and I'm not sure if I can (some options are grayed out/not available to apply in the ASUS UEFI, I'll have to double check which but I think CSM was one of them and so was Secure Boot)
- The little of changes makes a big impact: a user finally found the culprit by disconnecting an USB connector to his rudder pedals
- Some users suggested
registry edits and I do not wish to try such a thing just yet...
- Would using "S3" help in my post time? (I actually have no idea what this is, but I assume it's in the UEFI?)Currently
- I've settled with the post time for now...just wanted Windows to be up and working and also needed my computer up and running to type this.
- POST time is ~1 to 2 minutes on one of the 850 EVOs (I'll time more accurately as I update this log)
- Running Latest chipset driver, intel rapid, and bios.
- To be honest, it's kind of annoying at times due to how often a new build requires restarting
- Successfully installed Windows 8.1 Pro on 1 x SSD and 1 for other uses like games
- The RAID 1 popped up again and rebuilt itself.
That was my write-up so thanks if you made it this far and I hope I can come to a solution.
I've always liked ASUS mobos but this one has been a bit sour
I really hope I can resolve this issue. Thanks all. I'll be updating to this log.
