Thanks for the hint, I will have a look at Latencymon. I am more and more convinced that it has to do with the Sata HDDs (the first two months without them was trouble free, IIRC). In the beginning I thought the inevitable raid resync after a hard lock was only an effect. But with the immediate freeze after my last resync after switching to the Intel controller, and with the startup issues of the drives... Either the PSU is at fault or something with the drive management is wrong. Possibly a driver issue, right. Only, it is with MS drivers and Intel drivers, and MS drivers and ASMedia drivers in the case of the ASM1061. Don't know.

I think I will try with only one of the drives after the next freeze and finally eliminate both of them. I have already disabled the Intellipark feature (parking the drive head regularly; default is after 8 s) and Link State Power Management in the Intel Storage Console. We'll see. Also, I can install Win10 clean without any of the drives that were ever attached to the machine. I only doubt that it actually has anything to do with voltages, frequencies and such. I tried all this already. It has also proven consistent across bios versions.

Are the raided drives just used for data storage? Have you tried removing them both from the equation?

It is entirely possible that a drive not being able to wake up properly could lock up the whole system until it does, especially if there is something essential that the system needs to access from it.

The likelihood of this happening will be increased if you are getting a lot of hard page faults.

It would be very handy to get a full understanding of how all the different power saving features are linked together. For instance Window's power saving will often overrule UEFI settings.

Have you disabled hdd's from going to sleep in both the advanced power profile, as well as in the device itself in device manager? Also worth checking the controller it is connected to in case that is allowed to switch off to save power.

My external drive which is connected through my monitor never used to wake up after my display went to sleep, no matter what I set. Now with new version of windows, it wakes up correctly.

Excessive latency and page faults. The difference between the previous bodge job of an install I had to put up with and the new one is like night and day. Beforehand latency was in the 800-1000+ range for certain things. Now it rarely goes above 100 nanoseconds..

Thanks, I have a look.

Be sure to check my previous post just before that. It could save you a lot of time.

I have read it carefully.

EDIT: If I understand correctly, page faults indicate that the OS has to access the page file. The page file is not on the suspicious drives but on my M.2 PCIe SSD.

Hm, my highest reported hard pagefault resolution time just jumped to >50.000. But then, I really should do this after a reboot and when my array is not syncing.

It will also look for it in the original location if it can't find it in the page file. I can't say for sure everything that happens under the hood, especially if windows is still buggy, but say windows realises there are 2 copies of the same file on different drives, it may go looking for either.

Whatever happens, if you are getting high latency spikes and lots of page faults, it will be worthwhile doing a fresh install of the latest (November release, Dated 31's Oct) version of windows 10 as it resolved multiple issues for me. For the first time in months I have a computer that works exactly as it should.

The raided drives are for data only. I will try removing them after the next hard lock.

They don't host a page file.

Disk sleep is off, in the device manager in the options of the drives there is no power management tab. LPM is of in the Intel console (now).

The Intel controller has no power management tab as well. ASPM is completely off in Bios.


EDIT: I had this also under Win7 before Win10 upgrade.

Page faults occur for various reasons, most not being ominous. However hard page faults all result in a hardware interrupt when a page is not located within RAM, at which point a page is coped from disk and the process is allowed to continue. Memory corruption can also be a culprit. Simply watching page fault count is likely to make one think there are issues when there are not. Opening applications, and general use will result in page faults occurring as information is swapped into memory.

Latencymon is really only worth taking note of if the system is showing symptons of high DPC latency.

What about Display settings/Power and sleep/Additional power settings/change plan settings (for current plan)/change advanced power settings/Hard Disk/Turn drives off after (mine says 20 mins, I just set it to 0)

Also what power profile is loaded by default? I find this can be different every time I re-install windows. It can also change if Windows detects a serious crash.

This time around it went for Balanced. I would often have to wait a few seconds for disks to power back up. Setting it to High Performance keeps them running all the time, despite the 20 mins being in that setting I just changed.
