SmoothVideo Project → Using SVP → Lot of crashes / freezes using AMD HD6630M
Hi, with GPU acceleration enabled SVP hangs and crash MPC-HC every 3-10 minutes. Often the TLDR message popup (driver stop responding).
I've an AMD HD6630M and disabling GPU works fine.
The GPU is good, it passes stress testing using Furmark without problems.
Is there some log I can send you to analyze what's the problem?
What temperatures CPU and GPU while you watching cinema?
Around 55-60. It can reach 70 under stress testing like furmark.
However crashes happens even 1-5 seconds after start playing, they doesn't depend on temps.
It seems reducing "target frame rate" to 2x reduces crash frequency, but it still happens very often.

Please pass SVPmark test. And send your results to on-line database.
Done
berga_d
Your system passes this test successfully.
Hm... Can you get one more crash with SVP and after reboot show here SVPmgr log?
You can find it in %appdata%\SVP 3.1\Logs\log.txt. Open it in notepad, copy all and paste here.
Do not run SVP after reboot before open log-file.

It is ONLY GPU test, CPU stand by
While SVP load both CPU and GPU
Over 90% notebooks is aep arse, becouse its cooling system did't designed for cooling both heating CPU and GPU
Rimsky
SVPmark is passed. It loads CPU and GPU together with SVP core algorithms. It looks like it is not overheating. 
MAG79
nope
I belive its overheating:
a) SVPMark run about 1 minutes while SVP playing movies work 3-10 minutes
b) character of SVPMark load is peaks by test, while playing movies hardware load is constant
c) disabling GPU works fine / Furmark without problems

18:36:21.865; SetPriorityPlayer: 2Rimsky, I'm totally sure it's not overheating. This happens even just after 1-2 seconds. Sometimes it works for some minutes, sometimes it freeze after some seconds. However in general the computer doesn't hangs, only the player, and I can close it using task manager.
Probably it's something related with the Switchable Graphics sending screen data back and forth between Intel and AMD cards via pcie, or something related to OpenCL working unit size too big that trigger TDR.

You're not the only one who has TDR error / BSOD (0x116) in the last week.
May be there was a video driver update / public beta version released / etc?
No, the problem has always been there, using many different driver versions.
I don't get bsod, only tdr messages, and sometimes the player can't continue after driver reset and hangs.
I think the main problem are these tdr messages.
What does it change between the benchmark and the player? Because it is strange it hangs only during real playing.
berga_d
What does it change between the benchmark and the player?
- duration
- no output to renderer in the bench
try to set "overlay mixer" as the output option in the player
or even "null renderer", just for testing
berga_d
Real playing uses MPC-HC player, LAV decoder, ffdShow rev4500, EVR custom or madVR renderer by default.
You can change each of these components and look to the results.
Probably it is hardware acceleration of decoding in LAV or hardware acceleration of rendering in madVR. Check it first.
yeah, MAG79 is right, disable hardware acceleration in LAV first
Disabling LAV dxva seems to decrease the frequency of TDR, but it still happens.
Null renderer seems to work ok, but sometimes just click for opening some menu on desktop cause TDR or system freeze.
For example: I clicked there to open the drop-down menu http://sdrv.ms/ZNWLwl and computer screen freezed (audio still playing).
It happened before changing the setting, right after clicking to open it, but it may happen in other places too.
Using madvr or evr increase the frequency, and it may happen even without clicking anything.
I've trieied disabling GPU Preemption HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Scheduler\EnablePreemption, but then it freezes after 2-3 seconds of playing.
Disabling TDR stop TDR messages, but system freeze anyway.
berga_d
try to disable CPU turboboosts and downclock GPU to 400-300 MHz
berga_d
Try to get TDR error on any other OpenCL test/benchmark software. Does the error occur only on SVP?
Tried downlocking: same problem.
I tried with luxmark: using GPU only and the heavier Scene (room).
Luxmark doesn't seems to crash on its own, however I can cause TDR clicking many times on SVP profiles combo boxes, like in the screenshot I sent you before.
It seems clicking these drop-down menus increase a lot the frequency of TDR, even without any SVP video running during luxmark.
I don't know if other Windows animations cause this, I'll take a look.
berga_d
did you try madVR renderer? or VMR9r?
I've tried al renderers, but I have to use madVR because I need color correction.
I've done a couple of hours of testing with 1080p-24fps music videos on madvr, and now it seems ok. Sometimes it resets, but only sometimes, and it doesn't need reboot,
What I've found so far that seems helping:
1- Disabling DXVA (then I removed LAV and used only ffdshow, as it's not needed anymore, this improve TDR a lot)
2- Disabling "exclusive mode" in madVR (this stop player and computer crashes when TDR timeout happens: it will will just pause and restart after some seconds, and seems to improveTDR too)
3- Limit SVP to 60 FPS (using profiles sets to 2x30 2.4x25 2.5x24, I use a 75fps projector, improve TDR a lot)
4- Decrease both Motion Vectors settings to minimum (at least for 1080p seems to stop TDR definetely, other settings are at default)
5- Don't click buttons and menus while watching videos 
In general it seems that CPU load must stay under 60% to work without TDR. GPU load doesn't seems to create problems.

Thank you. I think your solution will be helpfull to anyone who has laptop with switchable graphics too.
Ok, I'm glad to help. After that couple of hours of testing I watched a video back on24p... I think I can't watch 24-25p anymore. Ever. 
Tonight I'm going to test it using a full length movie, then I'll write back if it crashes again.
Have you tried reducing OpenCL "working units"? I'm a C# programmer, so I don't really understand how OpenCL works, but from testing with different GPU programs some time ago I remember that bigger "working units" are faster, but sometimes they may block the GPU for too much time, generating TDR problems.
Let me know when you have some new beta to test.
Bye, Davide
EDIT: So, TDR happened after 10-15 min. I reduced to 2xFPS and then it worked, at least for another 20min, I test more tonight.
