Resource hog and then a crash

mrwilliams20602

I am new to Daz. I just unstalled it and was taking the tutorial and I noticed that PC was running really slow. When I got to the lighting potionh of the tutorial my PC crashed. UIpon estart I noticed that Daz was using 99% of my CPU power and my crash was due to overheating. So I overclocked my CPU and installed liqiod cooling. No luck. Their either. Up until now I thought I had a pretty good CPU.

CPU: AMD FX(tm)-8350 8-Core Processor, 4000 Mhz 4Cores 8 Logical Cores

16 GB of Memory

Which preview mode are you using? It should default to plain Texture Shaded but the behaviour you are seeing might occur if it was set to nVidia Iray mode and you lacked an nVidia card. forcing the CPU to do the work. The preview mode is set by the little sphere icon at top-right, just to the left of the camera/view picker button; you can also use the shortcuts ctrl-9 for Texture Shaded and ctrl-0 for nVidia Iray.

I agree with Richard, it sounds like you are using Iray on your preview without an nVidia card.

Also as a rule, if you're having overheating issues the worst thing you can do is overclock, since core heat increases exponentially when overclocking, even with water cooling. Especially if you increase voltage high to achieve it. Bulldozer architecture is known for becoming unstable due to high core temps (causing crashing) when overclocking high. Simply increasing CPU speed is not sufficient to achieve a stable high OC speed, voltage also has to be increased until stability is reached. Even with water cooling, since the temperatures increase exponentially with voltage you will be running higher core temps (not case [Tcase] temps) and that leads to instability and thermal issues. If you crashed, add water cooling but run at base clock.

All that being said, clock speed is not the issue with previewing or rendering of 3D graphics. High IPC, core count, stability and GPU CUDA cores (w/ Iray) matter more. This is not gaming, it's 3D graphics.

And just for reference FX does not use logical cores. The FX-8350 is eight physical cores based on the relatively lower IPC Buldozer architecture as well as resource costly cache sharing. True multi-threading using logical cores and dedicated cache for each core will not be available on AMD until Zen. FX and other AMD CPU's are terrific for lower-cost high core-count consumer applications like gaming, web browsing and watching video; which do not generally require sophisticated compute power. However as an "FYI" for someone new to it, 3D graphics and rendering require much higher and deeper compute capability, espcially with IPC (Instructions Per Clock) and better floating point calculation. 3D graphics (and video encoding BTW) are some of the most intensive compute processes a computer can be tasked with. Inexpensive CPU and consumer products can be pushed very hard in these applications.

Also if you plan on using Iray you will need an nVidia GPU card, of which it is totally dependent. AMD Radeon will not be recognized since it does not use CUDA cores. There are other third-party rendering solutions available too that are not dependent on CUDA. 3Delight, the other render engine in DAZ, also does not require an nVidia GPU.
