Topic: Win10 Pro 21H1 works for me finally

**** old posting about 20H2, see my update for 21H1 in post #2*****
Hi

FYI .. after performing a fresh installation of Win10 20H2 all random audio drops from a Win7 to 10 upgrade installation are gone. I can use MusicBee now with an ASIO buffersize of 32 and no issues, even when browsing the internet.

Very nice positive result and rock solid RME drivers !

Other nice thing, I do not need any 3rd party driver anymore, everything supported by Microsoft (nVidia RTX 2070 Super, Sonnet USB3 card with FL1100 chipset, Startech USB3.1 card with ASMedia Chipset // and Intel USB3 and Ethernet driver of the mainboard).

Intel Xeon E5-1650v4, Supermicro X10SRi-F
Windows 10 Pro with StartIsBack++, 8GadgetPack, O&O Win10 Shutup, Kasperski IS
UFX+ connected via USB3.0 to Sonnet Allegro Pro USB3.0 PCIe (Fresco Logic 1100 Chipset)
RME MADIface Driver 0.9723
MusicBee 3.3.7491

Re: Win10 Pro 21H1 works for me finally

Windows 10 21H1 - sometimes I had audio glitches.
The following combination of changes brought stability and very low DPC latencies also for nVidia

1. Mainboard: Supermicro X10SRi-F - downgrade BIOS from v3.1c to v2.0b (from 02.05.2017)
This is the BIOS version with support for E5-1650v4 (Broadwell-EP) and DDR4-2400, but without firmware upgrades for Spectre and Meltdown. I wanted to be able to deactivate those firmware upgrades entirely to get maximum performance of the CPU again.

2. GPU: MSI GeForce RTX 2070 SUPER Gaming X Trio - downgrade to nVidia driver version 442.74.
According to this nVidia forum thread this driver version has low DPCs: https://www.nvidia.com/en-us/geforce/fo … h-dpc-lat/

3. Windows 10 Pro 21H1
a)  disabling CPU firmware upgrades for Spectre and Meltdown
Using the tool InSpectre: https://www.grc.com/inspectre.htm
I do not recommend disabling the fixes if your system is connected to the internet, I disabled it only for testing.
b) using energy profile "Ultimative Performance" (already done b4, mentioned for completeness)
With Admin rights: powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61 and reboot.
Then choose it and usual tweaks: stop dia show, deactivate selective USB power saving
c) optimize Windows scheduler for background services (already done b4, mentioned for completeness)

4. USB3.0 card: Sonnet Allegro Pro USB3.0 PCIe, 4x Fresco Logic 1100 Chipset
Using Win10 21H1 Fresco Logic USB 3.0 eXtensible Hostcontroller driver 10.0.19041.1081 (already done b4, mentioned for completeness)

5. RME UFX+, firmware v46, MADIface driver v0.9735, connected to Sonnet Allegro  (already done b4, mentioned for completeness)
ASIO Buffersize: 32 samples @44.1

6. Deinstalled Kaspersky Internet Security, reactivated Windows Defender (already done b4, mentioned for completeness)
LatencyMon: much lesser DPC/lag when accessing the network/internet with Firefox and no audio drops

7. Results during/after 1.5h of music playback
- MusicBee 3.4.7805 using the RME MADIface ASIO driver: no audio glitches anymore
- RME driver settings: not a single CRC transport error
- LatencyMon v7.0:
- nVidia Windows Kernel mode driver (nvlddmkm.sys): highest DPC execution time around 400us, with Firefox up to 700us
- it's even possible to use Outlook and Firefox to access network, DPC exec times of nvlddmkm.sys stay under 850us

This looks very promising, same good performance like initially under Windows 7 it appears to me.
Not sure which change or optimization exactly fixed the issue with random audio glitches w/o any deterministic behaviour.
I assume that the sum of those optimizations finally lead to optimum results.

BTW .. to stay on Win 10 Pro 21H1 I added these two registry keys according to information found here: https://www.computerworld.com/article/3 … lling.html
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
- add DWORD TargetReleaseVersion = 1
- add String    TargetReleaseVersionInfo = "21H1"

Don't know whether this really works, lets see. 21H1 works quite nice, so I want to stay with it a little longer.

LatencyMon 7.0 results - 30 min - Interrupt to user process latency - meltdown spectre DISABLED:

 REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count:                 magentacloud.app.exe

 REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency (µs):   296,40
Average measured interrupt to process latency (µs):   2,596561

Highest measured interrupt to DPC latency (µs):       277,70
