Topic: mpc-hc + MadVR + SVP4 pro crashes in half to 1 hour of playback

I have some weird new problem.

When playing a movie on MPC-HC using the MadVR renderer and any setting of SVP 4 pro MPC-HC crashes mid movie, Usually it is either exactly 30mins or exactly 1 hour I get

"MPH-HC.exe has stopped working"

Last night I even got a 0xc00000002 BSOD!

Accodring to Event Viewer it is an "Access Violation (0xc00000005)" appcrash (I seem to be getting more and more of those on many apps and games)

and the faulting module is C:\Windows System32\Nvd3dum.dll

Using Windows 7 pro x64 with 4Ghz intel core i7-4970k, 32gb Corsair Vengeance Pro 2400 DDR3 RAM and 4Gb Geforce GTX970.

Is this an issue with "Nvidia CUVID" being enabled in in "LAV Video Decoder (Internal)" or is this something to do with MadVR renderer?

Please assist.

First thing to do is RAM downclock to 2133 or better 1866 with only half of sticks is used now (downclock through BIOS and RAM remove by hands).

Are you saying Downclock AND remove half of my RAM?! 

I have the Pro version of Windows 7 so 32Gb is used.  Win 7 pro can use up to 128gb.

Re: mpc-hc + MadVR + SVP4 pro crashes in half to 1 hour of playback

BSOD's are always about some hardware instability.
Nvd3dum.dll is a part of NV video driver.

Remove overclocking from GTX970, update or roll back video driver.

Re: mpc-hc + MadVR + SVP4 pro crashes in half to 1 hour of playback

Not permanently of course, just spend one day for testing if memory is the culprit. Ideally people use backup RAM or leave 1 downclocked stick in PC and if problem persists change with another.

I did a dual pass memory scan and the memory passed both scans.  I also set LAV back to "DXVX2 (Copy-Back)"  and if I still get any issues I will roll back the display driver and/or downclock my RAM.

I don't want to lug my hefty machine onto the table to remove RAM unless I have no choice as I have a dogey lower back  and my rig exceeds 50Kg, due to the high density sound proofing material lining the full-tower case.

I don't have overclocks on either my CPU or GPU as I am not an expert on voltage and therefore am not inclined to mess with it. (especially since overclocking voids warranties)

I am hoping to get an ASUS ROG GTX1080 STRIX 8Gb Graphics card in the near future and hope this GPU would not only boost my gaming expenentially, but allow me to run SPV4 at 120fps without frame dropping (and hopefully make my system more stable)
At the moment I can't exceed 100fps on my GTX970 without frame drops.

Ok, here is what I say:
- your Memory Modules already are overlclocked. Factory overclocked. If you don't want to take it out then at least do first part of downcloking it to 2133 or better 1866 in BIOS;
- I just further overclocked my RAM (1600 CL11 stock) from 2133 CL12 to CL11 and guess what? Looks familiar?

And the last thing. SVP itself doesn't interact with OS on that level so that it would directly bring BSOD. It's just that SVP stresses your PC (CPU and GPU and RAM) harder than most things do. So don't expect a magic "Fix my PC" button because you won't get it. You are not the first one with similar issue and definitely... no... de-fi-ni-te-ly not the first with system instability on PC with factory OC RAM.
P.P.S. And there is absolutely no point in upgrading your graphics card if the only purpose is SVP. You have unlocked (K version) CPU. It is made for overclocking so... either lower SVP settings or read/ask help on specialized forums, downclock RAM, slightly overclock CPU (43-44 for beginning) and live happily with 120fps.

Re: mpc-hc + MadVR + SVP4 pro crashes in half to 1 hour of playback

Thanks for the further info. @James D

I have downclocked my RAM to 1866Mhz

I am after the better GPU mainly for gaming, sorry for not mentioning that bit in the last post *blush
I also plan on buying the ASUS ROG GTX1080 STRIX 8G for the 2x HDMi 2.0 ports, so I can connect one port to my ASUS VG278 Monitor and the other to a 120Hz projector I plan on getting in the even more distant future, as I have been turning my rig into a 3D, 5.1 surround sound Home Theater/Gaming System, in my lounge room.  I just broke my bank with a set of 500w 5.1 THX Certified speakers, to connect to my Sound Blaster Zx, so those future purchases will be a significant while away

My GTX970 only has 1x HDMi 1.4 which can only output 60Hz. So I use the DVI-D Dual Link for 120Hz & 3D ATM.

I'm not game Overclocking my CPU anymore as, when I first got it I only overclocked it by 25Mhz and even though I have a noctua NH-L12 cooler I had a BSOD within half an hour of boot up and speedfan was detecting the CPU was getting hotter, and hotter. Maybe because I had to use some intel OC software, as all the areas in my ASUS Z97-K Mobo's BIOS for CPU OC were, and still are greyed out. My CPU is supposed to go to 4.4Ghz but all I can get is 4.0Ghz, without software OC'ing it.  I am loathed to software-flash the BIOS (in case I brick the Mobo),  and just touching the EZFlash button in BIOS freezes my machine, so BIOS is stuck on same version the MOBO shipped with some years ago. 
Even my technician can't get EZFlash to work, and refuses to software-flash the BIOS, citing the risk of bricking as his reason.

I have had to run my PC with the side panel off to avoid frequent and persistent BSOD's (CPU Stop Errors), ever since I got my current rig, so I thought the culprit was heat until a couple of days ago when they would come back now and then, but these BSOD's would not stay on screen long enough to read much at all, the system would power off in half to 1 second.

Lets hope I get a smoother running rig, but If I'm able to push past 100fps on SVP without dropping frames it's a miracle.

EDIT: There has been an increase of performance in 1080p Blu-Ray videos at 120fps.  I am only getting 2-3 dropped frames in the 10 mins I tested for. smile
However DVD's Resizing to 1080p are still not handling 120fps at all.  I get an instant 30 dropped frames with 9-10 frames dropped every second of playback. sad

EDIT 2: I've got better performance on DVD's now at 120Hz. I switched from "super-xbr" resize to "softbicubic (100)" resize.

Also in "Upscaling Refinement" I have sharpen edges = 4.0
crispen edges = 3.3
thin edges = 5.0
lumasharpen = 2.0
enhance detail = 4.0
soften edges = 3.0

and in "Image enhancement" I set the second "Lumasharpen to 1.50"

This makes DVD's look rather good imho.  Especially cartoons like my Family Guy DVD's as the thin, smooth line work make it look like blu-ray.

I also doubled the GPU and CPU queues, and allowed windowed overlay to present up to 4 advance frames, while disabling exclusive full screen mode and disabling DX11, as both these options killed the frames on my rig.

so far so good, I don't get any more than a dropped frame here and there, like native 1080p videos.  Fingers crossed this stays that way.

Thanks again @James D!!! big_smile
This kills two birds with one stone.  If things don't change my frame drop issue seems to be well mitigated. smile
