CPU optimize for rendering videos

vexboy132 · 9 Jun 2015 at 17:34

My CPU is not running at full speed (100%) when exporting videos but it is constantly changing percentage e.g. 8%,17%, 36%, 3% how do i get it to stay on 100%.
i know that if it stays locked at 100% the render times will be quicker than what they are currently at. They have been as long as 5+ hours

My specs

CPU - Intel 4930K 3.40GHz (Ivybridge-E) Socket LGA2011 Processor

Motherboard - Asus X79 Sabertooth Intel X79 (Socket 2011) DDR3

Graphics Card - Gigabyte GeForce GTX 770 WindForce 3x OC 2048MB GDDR5 PCI-Express

HDD 1 - Western Digital Caviar Black 3TB SATA 6Gbs 64MB Cache - OEM

HDD 2 - Western Digital Caviar Black 1TB SATA 6Gbs 64MB Cache - OEM

PSU - SuperFlower Leadex GOLD 850W Fully Modular "80 Plus Gold" Power Supply - Black

SSD - Samsung SAM 850 Pro 256GB 2.5 inch SATA III

CPU Cooler - Akasa AK-CC4008HP01 Venom Voodoo

What are you rendering with?

i am currently convering blackmagic DNG file to quick time files using da vinci resolve

The first generation Resolve systems were called the Resolve RT and Resolve DI. In 2008, da Vinci offered the Resolve R series (R-100, R-200, R-250, R-300, R-350, R-4K, R-3D), replacing da Vinci’s proprietary parallel processing PowerPlant cards with parallel processing NVIDIA GPUs, enabling super-computing image processing and a significantly greater feature set.
Looks like it uses gpu not cpu

Capping out core usage on CPU/GPU is almost never a hardware issue. You have a software setting/problem/incorrect use case assumption.

If it's a GPU tool it would make sense you're seeing low CPU usage.

Check GPU usage using an appropriate utility, e.g. GPUZ.

I forgot to add photo in the main post here they are (images taken during render videos)

CPU-Z

task manager

i would like to point out that i want my CPU usage to be stuck on 100% when rendering
so that the CPU usage history creates a straight line instead of jumping up and down

looks like the software only uses the 6 logical cores and doesn't use hyperthreading
a) your subsystem isnt optimised so cpu is starved of data
b) as previously pointed out the rendering may be gpu dependant, check with the software vendor

from da vinci website

DaVinci Resolve is scalable and supports multiple GPUs all working together as found in the new MacPro, as well as the latest Windows and Linux computers. You get support for up to 8 GPUs so that you can build dedicated systems

I would love to see a gpu-z graph
