I'll start off with the specs:
MB: Asus Z170-A
CPU: i7-6700k @ 4.6GHz
Cooler: NZXT Kraken x61
RAM: Corsair Dominator Platinum 16GB 2666MHz @ 2676MHz XMP Profile
GPU: EVGA 980ti Hybrid @ +90MHz base clock/+500MHz memclock (Running WQHL 620 drivers... waiting until Nvidia is well past the current driver issue to upgrade)
PSU: Corsair AX760
SSD1: 850 EVO 500GB
SSD2: Crucial M4 128GB
SSD3: OCZ Agility 3 120GB
HDD1: Seagate Barracuda 7200RPM 2TB
Monitor1: ASUS ROG SWIFT 27" 1440p 144Hz
Monitor2: HANNS-G 27" 1080p 60Hz

My computer is -S-L-O-W-. To clarify, this is day-to-day, non-gaming performance. In games I'll get 144FPS without a struggle @ max settings. But daily usage, loading things like chrome is slow. Loading games up is slow. Boot is slow (~1:30min boot time) (looking at Task Manager right now -- Last BIOS time: 28.3 seconds, another full minute until I was even at my desktop). BIOS post is extremely slow. I'll sit on a black screen with only an underscore ( _ ) displayed for about 10 seconds before anything happens. Usability after boot is slow. If I go too quickly and open chrome as fast as I can and start typing, the input is extremely laggy and characters will still be typing into the search bar ~25 seconds after I've actually typed them. My startup is clean, only Corsair Utility Engine (had no impact on my previous, 2011 computer build), NVIDIA Backend and Rainmeter are allowed to start. For reference, my old build (2500k @ 4.5GHz, Crucial M4 as C:\, 670 FTW edition) booted to a completely usable desktop (while on Win10) in about 25 seconds -- with more programs running on startup than this new build has.

This computer is also having random issues, i.e.: Rainmeter does not save settings, so I have to re-do my layout every time I boot. If I play Rocket League and ANYTHING is open on my second monitor, GPU usage drops to 0% and the game sputters along at 2 FPS. My graphics drivers have crashed in the past (especially when starting 3DMark). I noticed the drivers crashed a lot more when I was tuning in my max overclock on my 980ti, then I backed off the max by 15% to give a solid buffer. I've also had an issue submitting benchmarks, where the result was declined due to time differences. I noticed my BIOS was several minutes off, and have since fixed that. Don't know if that is still an issue - I manually set the time using www.time.is since Windows refuses to update the time. My result from time.is is currently: 2.9 seconds behind

980ti PrecisionX settings are: +90MHz clock, +500MHz mem clock, +87mV Overvolt, power target 110%, cpu temp target 91C (never even makes it halfway there)
CPU was auto-overclocked by ASUS's EZTuner BIOS utility.

Here's my main issue: when I was on Windows 7 (briefly, only installed it because I don't have a Win10 USB or CD) I went ahead and did some benchmarking -- the system scored amazingly, as expected. Samsung Magician reported max 850 performance, system was OC'd exactly as it is now and I had no instabilty or other issues.

As soon as I came to Win10, all of this started happening. My 850 EVO is only working @ ~120mb/s seq read, ~90mb/s seq write, in addition to the other problems I've outlined above.

Some troubleshooting I've done, mostly aimed at the slow 850 EVO which I'm targeting as my prime suspect:
- Clean Windows 10 install
- Verified 64 bit install
- Verified ACHI mode in BIOS
- Verified plugged into Gray SATA port on mobo, verified SATA 3 6GB/s port
- Verified through command prompt that ACHI mode is enabled
- 3 different SATA cables
- Verified Samsung Magician has SSD set to maximum performance under OS Optimization
- Boot to safe mode to attempt to install driver (did nothing)
- Another clean Windows 10 install
- Verified 64 bit install
- Verified alignment on 850 EVO (C:\) - results:
Partition # | Type | Size | Offset
Partition 1 | System | 100MB | 1024KB = ? divisible by 4
Partition 2 | Reserved | 128MB | 101MB = 101000KB = ? divisible by 4
Partition 3 | Primary | 465GB | 229MB = 229000KB = ? divisible by 4
Partition 4 | Recovery | 450MB | 465GB = 4.65e+8KB = ? divisible by 4
- 3x different benchmark programs -- Samsung Magician, UserBenchmark, CrystalDiskMark -- all consistently low results on 850 EVO.

Does anyone have any clue what could be wrong with my build/Windows 10?
 
1| Have you verified that your installer isn't corrupt? Recreate your bootable USB installer following this guide.
2| You may want to change the CMOS battery with a fresh cell as the issue with the BIOS time being off can either be the OS or teh battery showing failure points. If the battery has been changed, you can try and perform a repair install and see if your system is as it should be.
3| Have you made sure your BIOS and device drivers are up to date?
4| As per your manual, page 1-24, you should be running your Samsung 500GB OS drive off SATA6G_1 port.
5| Are there any firmware updates for your SSD's? I know the M4 has one as I own one too but that update was ages ago 😉
 
The problem is XMP. I wiped to Win 7, reset CMOS battery and started from there. As soon as I turn on the 2666MHz XMP profile is when all of my problems start. Haven't found a fix so I've had XMP disabled. Reinstalled Win 10 and was able to recreate the issue by turning XMP on.

Confused as to how something that's supposed to make RAM run faster is causing all of my drives to slow down - with XMP on all 4 drives I have slow to a crawl.
