Member Martin Maximilian Michl Posted February 6, 2018 Member Report Share Posted February 6, 2018 (edited) Hello I suffer sever system crashes when I bake AO, but also under other unidentifiable situations. This makes it almost impossible to use 3D Coat. system specifications: Dell Xeon Precise Tower 7910 20 Corre XEON e5-2604 v4 @ 2.4GHZ 80Gig Ram Dual Geforce GTX 980Ti Windows 10 pro 3D Coat 4.8.10 Problem occurs in 3D Coat OpenGL and DirectX Report: 3DCoat seems to use my graphic cards on a special high level monitor goes up to high performance and temperature then it crashes my whole system, leading to a instant shutdown/restart this occurs under normal usage after a while and always when baking AO I recently changed the TDR values of the registry to 60 (as recommended by Substance Painter) but this didn't solve the problem. I will attach a video showing the process to illustrate the problem It would be great to hear if this is a known issue, for it only occurs on this machine (Xeon, Dual GTX) Thnx for help Martin Edited February 6, 2018 by Martin Maximilian Michl 1 Quote Link to comment Share on other sites More sharing options...
Member Martin Maximilian Michl Posted February 6, 2018 Author Member Report Share Posted February 6, 2018 here a video of the situation it would also help to get some hints how to monitor this error in a better way 3dcoat_crash.m4v Quote Link to comment Share on other sites More sharing options...

carrots Posted February 7, 2018 Report Share Posted February 7, 2018 Hello Martin Maximilian Michl! The failure of your computer arises when you load the graphics card, the problem is related to your hardware. The cause of the problem may be: 1. Power supply is insufficient. 2. Overheating of the video card (insufficient cooling). 3. The video card was artificially overclocked. Other unknown reasons are possible. Perhaps it will help reinstall drivers, or reduce the clock speed of the video Quote Link to comment Share on other sites More sharing options...
Reputable Contributor AbnRanger Posted February 7, 2018 Reputable Contributor Report Share Posted February 7, 2018 That's right. It could be a bad/corrupt graphics card driver, but what it really appears to be, IMO, is the system is overclocked and any heavy load crashes. The best way to be 100% sure it isn't 3D Coat is to run a stress test of the CPU using a free app like Prime95, and there are some stress/performance tests for graphics cards, online as well. Alternatively, you could just render something with Blender Cycles....one in GPU mode and the other in CPU only mode. It should stress them long enough to crash your system, if it is indeed hardware. Halfway through this video, he has the same thing occur, when playing a video game. If you have multiple graphic cards in your system and 700W or less Power Supply, it might not have enough power to operate under a heavy load: Quote Link to comment Share on other sites More sharing options...
Reputable Contributor AbnRanger Posted February 7, 2018 Reputable Contributor Report Share Posted February 7, 2018 ...by the way. AO, curvature, or Light Baking works fine on my system. So, that would indicate a hardware or driver issue on your end. Quote Link to comment Share on other sites More sharing options...
Reputable Contributor AbnRanger Posted February 7, 2018 Reputable Contributor Report Share Posted February 7, 2018 ...after looking at your system specs, I think I see the problem. Off the shelf systems are NOTORIOUS for having weak power supplies. They are only designed to handle the hardware they come with and that is all. Even if you have a second expansion slot on your motherboard, that doesn't mean Dell provided a PSU equipped to handle a second card. I build my own systems because off the shelf systems have the cheapest parts possible. The Power Supply and motherboard are typically the cheapest they can get by with. The first thing I would do is power you system off > unplug the power cord > take the 2nd card out of your system > test and see if your system crashes, again.

Member Martin Maximilian Michl Posted March 18, 2018 Author Member Report Share Posted March 18, 2018 Hello thnx for your reply, I will run some stress tests on the system to get closer to the cause one thing I can tell is, I am constantly rendering Vray GPU (als GPU and CPU combined) scenes. the graphic-cards fans work like crazy, but it never crashes the system. thnx Martin Quote Link to comment Share on other sites More sharing options...
