DPC latency and hard page faults nightmare

[deeaa]

So,

I updated my machine from i5 2500K with 8gb and an ASUS board to i7 6700K that I run at 4.5Ghz with 16GB of 2600Mhz RAM and a Samsung VNAND drive right on the motherboard. Asus Maximus 8. With hopes of speeding up the system of course.

Well, it ain't working. The system is clearly slower than the old one was. Boot time is like 5 times what it was in old machine and I get weird lags and holdups which render the machine nigh useless. Even opening file manager on c drive sometimes takes seconds. When it works it is fast and then...suddenly it just halts playing back basic audio and DPC latency monitor and system monitor show huge peaks in page faults and dpc peaks reporting 'this machine may not be able to play multichannel audio without issues'.

Of course there is a bit more oomph in calculation power and plenty of memory and it loads programs super fast...

BUT yeah...there is terrible DPC latency and these weird holdups where the whole system sort of halts for a second or two even now and then. Latency monitor constantly shows barely acceptable levels and peaks now and then so that even like video playback halts for seconds randomly. Got hundreds of thousands of hard page faults in resource monitor.

I have tried removing each component both physically if possible or from Device Manager but nothing seems to help. It's like it just decides to suddenly peak everything. I tried not overclocking, even reinstalled win 10 twice clean and nothing seems to have any effect. This is terrible.

I'm guessing it is mostly a hardware thing then? The motherboard is clearly geared more towards gaming use not heavy AV work I use it for, maybe that is the issue? I tried not installing mobo drivers, swap memory module places, removing display card, sound card....no difference. BIOS safe values, hours of trying stuff there like disable virtualization, disable everything I don't absolutely need, disable USB, network, all I can...running out of ideas. It just keeps having these freeze fits in media playing.

Is this a general feature of 8 series mobos, are these so gaming oriented they can't even play multichannel audio and video without hiccups?

Any ideas?

could be an issue with the SSD. have you tried troubleshooting in that direction?

I have same suspicions, and have a nagging feeling it is due to the Samsung 950Pro VNAND drive right on the mobo. It limits some bios options having it there, and also has an annoying habit of dropping out as boot drive by itself (meaning, if I go to bios and change most anything about it, and exit and save it usually tries to boot from anything BUT the M.2 disk. So I have gotten used to always checking hard drive bbs priorities whenever I even visit the BIOS because chances are it has dropped the M.2 drive entirely from the list.

Also, it seems to me that sometimes, for a while, all is well and I can run audio and video for a while...and then it starts to do these halts.

Another strong contender is my audio card which is a rather pro level firewire card, Focusrite Liquid 56...I had HUGE issues getting it to work with this mobo.

First I bought a DeLock FW400 card and it didn't work...simply the audio card refuses to be found thru it even when I tried legacy drivers...

Then I bought the ASUS ex Thunderbolt card which also works as Firewire with an adapter, and while the Thunderbolt in itself worked fine I could not get the sound card to work with that either. So now I have a FW800 card that cost nearly 200 euros and it finally works albeit even with that it first appeared not to, took me several boots and attempts to get it running fine, and sometimes it still fails to find the card attached upon boot.

But, I can't change the soundcard, my entire studio is built around it...and now it works fine....EXCEPT I have to keep buffer at 2024 which is insanely large.
