Intel Ultra 9 285K - Asus ProArt MB - RTX4090 = Substantial upgrade on DAZ3D (CLOSED)

The newest firmware for the Asus ProArt z890 motherboard effectively does a far better job at stable OC, and power management. In combination with the latest studio drivers from nVidia, the RTX4090 set at maximum performance has really boosted the rendering power within DAZ3D studio. Render times are cut down drastically - using the following images as a example took me 10 minutes on an 11900K - OC'd using the Gen9 character below at 3000x3000 pixels.  These images now render within 3 minutes at the same resolution using the Intel Ultra 9 285K. The iRay rendering view now has low lag time when previewing within the build windows too. 

The second part to my post is the video I used to extract the maximum performance out of my computer system to keep the Ultra 9 285K at top performance levels, should anyone else here be using this processor to do rendering.  This processor over clocks very differently, and care is needed to ensure lower temperatures and the prevention of hardware errors.  Note - high 
performance can be had by simply using the OC profile that comes with many boards, but that is a very slight performance gain. I used the manual adjustments - manually adjusting the core multipliers and undervolting the CPU by a small margin. This method works well and will significantly improve data handling, rendering times and Geekbench 6 scores. As of today, I am running a Geekbench 6 score of 22876 pts with a moderate OC.    

A great way to tune prior to making any major OC changes is to use Intel's Extreme Tuning Utility.  Below is a slight overclock without the voltage offsets applied. I've used slightly high multipliers on each of the performance cores below. 

Here are some screen shots from a test shot using a Gen9 model with a studio portrait environment and simple point lighting with GN Zhangli HD (G9 model) as my main subject. The render output has been set to 3000 x 4333 pixels. This image would have taken 34 minutes with the 11900K w/ 128 GB DDR4 - 3600 MHz ram w/ the RTX 4090. Remember that you must set the preview window to anything other than iRay while you are rendering a full iRay image file using an RTX nVidia card, or you will significantly increase your render times.

Image 2: 7 min and 17 seconds later - my Gen9 render is complete. 



Image 1:  shows the settings  - note: iRay preview is turned on - however, when I engage the render button for my full size render, I will switch this preview to wire frame to preserve VRAM and CUDA core processing. 

Thanks for sharing your results. It sounds like you know what you're talking about. 

However, I'm curious... Since you're overclocking and concerned with temps and stability, why did you choose the ProArt over the ROG Strix? I'm planning a new PC build soon and would appreciate any insight. 

On a side note... NVIDIA spells it with all caps, or sometimes Nvidia. Not "nVidia". And it's Iray, with a capital I. Not "iRay".

The ProArt board was what I could get at the time and seemed marketed at the producer rather than the gamer. The ROG Strix has more connectivity and is functionally a better board in this regard - and it was however, 2 weeks away with ordering.

Point taken.
