Found your problems. You are using an unstable OS and mining to a company that takes a cut for no good reason because people are too lazy to manage their own wallets.

never use fucking sata i already said it...not with adapters not any other way, only 4pin or 6pin molex
since i stopped using sata for powering risers 99% of my problems are gone

Power limit decreases to 75%, then it will go well.

I have these risers:

I use the 6pin to sata adapter.  I power only 2 risers with each sata cable from my PSU, as per the norm.  My 1060 rig uses molex adapters and I never tweaked virtual memory on that PC and its fine.  Do you think these 6 pin adapters are requiring it though?

Have you used those risers before? If not - pull them out and wipe the small PCIe 1x gold fingers with isopropyl alcohol or some such. Some batches of risers come unwashed from the "factory" after manual USB3 socket soldering. Flux (rosin) gets everywhere and in my case is the primary cause of all mysterious problems.

how did you connected your risers? use 4pin or 6pin never with sata and you need to increase virtual memory thats one of the most importand things

So keep in mind when tweaking the values and applying them to all your cards, it's only going to be as good as your worst card - so it's quite possible you have one bad card in the mix (or picky card), and it doesn't like to run restricted power or OC'd.  I would try applying the settings one card at a time and let them run for 24+ hours - more than likely this will help you identify the offending card.

You could also try one of the Linux systems and see if you have the same issue, to see if it might be driver related or not - if you see the same thing on the Linux side, then you can be pretty confident it's hardware related.

Using Nicehash miner, sorry I should have included that.  I haven't done much to background processes and I haven't tweaked virtual memory.  I have a 6x 1060 rig that's stable as a rock, I never did anything to the virtual memory on that one either.  Is it worth a shot? 

What miner are you using and how much windows bloat have you killed off from background processes and is virtual mem set to 16Gb or more?

Rig:

5x Zotac Amp Extreme 1070 ti
1x PNY Dual Fan 1070 ti
2x EVGA G2 Gold 750 using the Add2PSU adapter.  One PSU powers 3 cards and all the risers.  The other PSU powers 3 cards and the mobo/SSD
4gb Ballistix DDR4
Asus Z270-A
Intel Celeron CPU
120GB Adata SSD
Windows 10 64bit
Nicehash Miner



So I initially got this rig without the other 5 Zotac cards so I just set the motherboard on a box and used the single PNY card for a couple of weeks while I waited for the backordered Zotacs.  Once I got a stable OC on the card, I ran the system without issue with the card plugged straight into the motherboard, no riser.  

Last Thursday I got my other 5 cards so I fully assembled the rig.  I got all the components in the frame and all the cards on the risers.  Booted up fine and I got all 6 cards detected by doing the bios mods for this mobo that are on youtube.  Everything looking good I thought.

I put a mild OC on the cards and started mining.  About 12 hours later the machine was frozen, locked up.  I rebooted and halved the mild OC to just +100 core and +200 mem.  Started mining again, froze.  Ok...so I did no overclocks at all, stock speeds.  80% power in MSI afterburner this whole time, FYI.  Started mining again, froze up in just a few hours.  What the heck?  Then I tried one more time, stock speeds but this time 90% power instead of 80...although 80 should be just fine especially with no OC.  Froze after 10 hours.  

I don't get it.  I'm pretty sure my motherboard and RAM are fine, considering the machine ran for a couple weeks with no issue when I just had the single PNY card.  I have 6 extra risers for a new 1050 ti build I have coming this week, should I try swapping out the risers and see?  Anything I'm overlooking here?  

Its so frustrating to see your rig frozen up on your dashboard and you are helpless at work. Sigh
