well, see that makes PERFECT sense and is a great answer!!!

thank you and thank you for all of your hard work. Best audio interface. Nothing else holds up.

Again, thought there was something wrong with my system, so I figured I would try and figure it out. This thread has been immensely helpful! thank you to all of you

No one said you do. But the so called 'surprise removal' is best working with USB, with the old FireWire driver less so. But even with USB it could happen that the player software hangs then. At least no BSOD - in most cases.

I've never had that before - with any interface. It's not a huge deal, I was just wondering if something was wrong with my config or PC.

I've used:

Firepod
Tascam 1608
Focusrite saffire/clarett interfaces. (I've straight up pulled the cord out of the USB port and nothing happened with these!!! hah)

Also, the folks at the Reaper forum who responded to this do not have this issue. So I am sitting here thinking there's something wrong with my setup. Or what if power goes out, and only my PC is connected to the UPS? The UPS would be ineffective since the pc would just BSOD haha. And the RME driver is "transferring data" the entire time like if I'm playing a video in VLC or watching a youtube video. How can I shut it off those times and nothing happens? So the whole time I'm worried if there is something wrong with my config. I am not blaming anyone or anything, just wondering - inquiring. That's all.

Let's not be too astonished now. It's just a question. Everyone is fine, no one has been actually hurt by this thread, and actually I got some great, concise advice!!

and IM SO GLAD because this interface is my FAVORITE that I've ever had

Really, the answer is simple to me:

Don't do that, dumbass

Just don't shut the damned interface off while Reaper is on, or make sure to set reaper to dummy audio if i walk away and forget to shut down before the end of the night.

haha

just making sure there isn't something else wrong with my system. Whatever little niggles I have to deal with are fine, considering how awesome this 19 year old interface is. haha.

So let's chill. I'm not hurting anyone

True, I over read that. That is indeed a false expectation.

I am astonished that someone expects switching off a hardware while used (with ongoing data transfers !) will NOT cause a BSOD...

happens with all DAWs.

And since there are many RME users and specifically even FF800 users (over the past 18 years), I am certain it would have been squashed. As posted in the first post, this has been addressed there to no avail.

this thread, however, has been VERY helpful

If it does not happen with other asio hosts it could be a reaper bug. Yes it is the RME driver cashing, but reaper causes the crash. Just a thought of course

Re: FF800 BSOD on shtdwn, unusable after Sample rate/Buffer length change

null@example.com (jasonbrianmerrill) — Sat, 17 Jun 2023 01:50:39 +0000

yeah, still happening. Can't really figure out why. Only happens when:

1. Reaper is open
2. FF800 driver is being used
3. FF800 is shut off

ofc, I could just not shut it off - but I have an auto shut off for my studio at 3am in case I leave it on, but keep in mind that no matter HOW I shut it off, the BSOD happens.

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.

 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:                 searchindexer.exe

Re: FF800 BSOD on shtdwn, unusable after Sample rate/Buffer length change

null@example.com (MetalHeadKeys) — Fri, 16 Jun 2023 13:48:28 +0000

I just noticed, your previous power settings' screenshot!

You need to set minimum processor state to '100 percent', as well, and 'Turn off Hard Disk' to "Never".
Save that as your power plan, and you can change power plans depending on your PC usage, if you don't want to keep the CPU to 100%!
Also, disable any on-board Sound card!
Also, you should consider disabling Cortana and OneDrive, or at least stop the services from running when you 're using Reaper
You can, also, check the Studio Drivers for nVidia GPUs, if your card is supported :https://www.nvidia.com/Download/driverR … 730/en-us/

Also, check your BIOS PCI settings and disable any power-management setting for the port where you have the Firewire card connected!
Restart and check with Reaper! Do you, still, get BSOD or dropouts? Has performance improved?

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.

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.

Well, I think you know the next step!

Disable Windows Search Service: https://www.makeuseof.com/windows-search-indexer-guide/
It's described on the lower half of the article, labeled " Is It Safe to Stop Windows Search Indexing? ".

Then check with LatencyMon, again, and post an update!

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):   1192.50
Average measured interrupt to process latency (µs):   4.709173

Highest measured interrupt to DPC latency (µs):       1188.60
Average measured interrupt to DPC latency (µs):       2.237028

 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:                 searchindexer.exe

Total number of hard pagefaults                       22503

Hi, again!
Yes, latencyMon report seems very good, except of the Hard Pagefaults Count.
Here's a good article I found on msmpeng.exe, that you can try: https://www.freecodecamp.org/news/what- … isk-usage/

Well, I do wonder about one thing. My DAW is always connected to the net, so i always need realtime protection on, I think - I am not totally up on stuff these days but I wouldn't want a worm or something to make its way into my pc - I don't click on any risky links, and actually I scan every exe or suspicious or potentially harmful file with windefender as it is.. but I am not sure I should disable realtime scanning.

The exclusion thing, however - WHY does windows defender scan its own folder? That's odd. I'll try it. Maybe its a place it puts files that are downloaded to scan?

anyway, that's all done.

Now, here is another on how to optimize Windows for "Background Services": https://www.thewindowsclub.com/processo … indows-7-8
Also, on the same "Advanced" Tab, there is a "Virtual Memory" Setting. Set that to half of your physical RAM! So, for 64gigs -> 32768.
If you click on the "Change..." button, you will be presented with a few additional options.
Set both Minimum and Maximum value to "32768". If it's too much space for your hard drive set it to "16384".

done!

Also, I would disable "Intel SpeedStep" and "Intel Speedshift Technology", in the BIOS.
Try these tweaks, and please, report back!

next reboot this will also be done!
