Win 10 AU - Very High ISR counts for DirectX Kernel

[Aphantos]

Yeah, and more, tried various obscure drivers reported to function better, other tweaks, disabling various hardware, drivers and service, but I just can't get this Z170 Pro Gaming, i5 6600k, GTX 1070 to run better than my i7 3770 and GTX 970. If I can't return the MB I'll just install my old MB and CPU until I can afford a new MB. I'll most certaintly not buy ASUS again, I've had so many issues with their products. First the phoebus, then the gladius and now this motherboard.

I'm going to see if I can find a windows 8 install that will work (not sure i can install windows 7 on this build) and see if anything is different.

I am also considering ditching the board. The downside is that there aren't many other boards on the market with the same features. And well, my build is color coordinated too :)

 

[xilolee]

Both: did you disable hd audio controller (BIOS)?

 

[NoChance]

Yep. When I did the fresh installs, I disabled every single extra item in the bios: audio, lan, bluetooth, wifi, asmedia USB, asmedia SATA, thunderbolt etc. I tried with as few items as humanly possible.

 

[Aphantos]

Thanks to great customer support I was able to return the motherboard and instead I got myself a MSI Gaming M7, somewhat sad solution to the problem. Now I don't have any of the problems, haven't even had to tamper with power saving features or look for better drivers. Playing overwatch now only uses 70% of my CPU instead of 100%, and is able to fully utilize the graphics card without dropping any mouse inputs, causing fps drops nor audio cut-outs.

Hi again ...


ASUS is pretty good about returns. As I mentioned in BestLux's thread: for Asus "when they're good, they're very, very good, and when they're bad, they're horrid" (you might remember those lines from an old nursery rhyme ... Yes, I'm ancient).

Glad that the MSI board is working well. BestLux posted the MSI Z170 model board that solved his problem, too. Any company can have a troublesome model, even the best firms from time to time. [Ages ago, I used to like the thrifty AOpen boards ... no frills, but good value for the money]

Hope things work out.

 

[NoChance]

I'm going to try on another motherboard. If that doesn't work, I'm going to return the card.

 

[NoChance]

ok. some good news for some of those who are having similar issues.

I have eliminated all of the USB/WDF01000.sys ISR issues by not using the Microsoft USB drivers, and instead using the Intel USB 3.0/3.1 drivers for windows 10.
Only the catch is that Intel HASN'T RELEASED any USB drivers for windows 10.... well, you have to take a leap with me and try out the Intel USB drivers here: Please read the instructions. These drivers eliminated half of the ISR issue. Now All I need to fix is the nvidia driver issues.

 

[xilolee]

Still fighting? :banghead:
What motherboard are you using?

 

[NoChance]

Still fighting. Asus Z170-premium (BIOS 1902) and I just tried an Asus Maximus VIII Formula (same results).

I'm looking at a GPU trace dump as I type. I'm hoping I see something there.

 

[xilolee]

Did you try XMP?

1. enable the ez_xmp switch on the MB
2. remove the two memory sticks in A1 and B1 (1rd and 3rd, starting from cpu)
   If you don't want to remove the two sticks, you can disable their channel from the bios:
   • channel A dimm control: disable dimm0 (I think this should be A1)
   • channel B dim control: disable dimm0 (I think this should be B1)
3. bios, advanced mode, ai tweaker:
   • ai overclock tuner xmp
   • cas latency 15
   • ras to cas delay 15
   • ras act time 35
   • command rate 2
4. bios, advanced mode, ai tweaker, tweaker's paradise: DRAM voltage 1.3500V
   There's another setting named "dram vtt voltage", but it is not like the above.
   3.bios, advanced mode, advanced:
5. graphic configuration, primary display: peg
6. peg port configuration, pciex16_1 link speed: gen3
7. and save the settings...

Why those values?
Because:

1. I didn't find your ram model F4-3200C14D-32GTZSW (2 stick of 16GB) in the MB QVL
2. I didn't find your MB model z170-premium in the RAM QVL
3. I found F4-3200C15D-32GTZ in the MB QVL, and they used these settings:
   • 2 DIMMs
   • 1.35V
   • tCL 15
   • tRCD 15
   • tRP 15
   • tRAS 35
   • Command rate 2

 

[xilolee]

I noticed there's JEDEC 6 (in your speccy log) with those values, and the voltage is less than what I wrote... Maybe you'll be able to find and set that profile.

JEDEC #6
Frequency 1066.1 MHz
CAS# Latency 15.0
RAS# To CAS# 15
RAS# Precharge 15
tRAS 36
tRC 50
Voltage 1.200 V

 

[NoChance]

Yes. I've run both at the rated XMP and the jdec 2133 speeds/timings.

I've got a gpuview trace of the issue. The context queue for fallout 4 is never getting emptied, even though the hardware queue runs dry. Seems odd.

Hi all


Just curious ... did you try the 1.7 patch for Fallout 4 released in late August? It was said to be nearly 2 GB in size, and to have patched a fair amount of issues.
'Fallout 4' Latest News & Update: Bethesda Releases New Patch For PS4, Xbox & PC; New Mods For PS4 Not Coming Soon : Games : Gamenguide

 

[NoChance]

Yeah. Steam AutoUpdates and makes it really hard not to.
1.7.15.0

 

[NoChance]

Does anyone know the differences between how eufi and non-eufi installs affect windows 10?

 

[NoChance]

I thought I'd update this as I see there are some incorrect things still floating around in other forums.

The usblyzer is a red herring. It was added just before this dump to see if I could log USB commands in the hope of identifying a USB driver bug. It has been removed.

To date, the issue still occurs up to and through Nvidia drivers 375.57.

It occurs across 3 motherboards, (Asus Z170 Premium, Asus Maximus VIII Formula, MSI Mpower Platinum), on all bios revisions of each board, on Windows 7 and Windows 10 (Eufi and non Eufi) on all Nvidia drivers since card release, on 2 separate nvidia 1080 gtx founders edition cards.

So so the issue still exists. When I get it solved, I'll be sure to post here.

 

[OldGrayGary]

Thanks for keeping us updated!

Hi there!
Sorry for bumping an old thread but I'm having the exact same issues with an Asus Gl502VSK laptop, I have done everything under the sun in this thread and others, tried numerous resets and tweaks, alas no joy.

Any help would be much appreciated, I'm happy to post traces and the like if needed.

The issue appeared randomly after one of the windows updates a few months ago and I've been attempting to battle it ever since. I get high FPS in games however it stalls for a few seconds then catches back up, audio popping and real time video playback also suffers.

The more threads I look at regarding this issue, the more threads I find that it's an Asus product having the issue

Warrenty is not an option (had terrible temps out of box so repasted and Asus will definitely know)

Please help

I know this is a necro thread, but if anyone is still looking for a solution after all this, my problem was dirty power. I was plugged into a failing surge protector, and as soon as I replaced it, my latency was gone. Note, I also unplugged extraneous USB connectors from the motherboard while I had it unplugged, but as I was doing that I bumped the outlet and my monitor powered off from the protector. So I replaced it, powered up, and bam! After tearing my hair out for a week, running latencymon and replacing drivers, changing MSI registry keys, reinstalling windows, changing bios settings, audio settings, display and network settings, and whatever else, the crackling is totally gone. And to be clear, I had the same symptoms as other people on here, crackling under CPU load, high ISR and DCP counts for drivers, random but infrequent BSODs, so it definitely felt like I had a bad board after all that diagnosing, but nope!

So if none of these other solutions have been able to help, try another outlet (on a different circuit) or surge protector.
