Sorry, I was meaning to send that to Rosco, my bad. Peace, Jon

Ryzen Master is a software available on AMD's website that can control CPU & RAM usage and overclocking. It will be slower......but still faster than 90% of the cpu's on this forum! Fully maxed out and overclocked our systems will crush most dual Xeon systems at a fraction of the cost! I have already beat some of them rendering benchmarks here. Good Stuff!! Once you get the wrinkles ironed out you will be very happy with the stability, computing and rendering power, it's the best computer I've ever had. Did you know that a Ripper is really just a Epyc processor for retail?

When you start to use more intensive programs while raytracing, you might get 'bottlenecked' at the amount of RAM that you have. I regularly work using about 46 GB of RAM, and as said before the Ripper loves all the DIMM's to be filled.

Here is my parts list attached. The one thing that has changed is the RAM--the new RAM is 2 kits of Corsair Dominator CMD32GX4M4B3200C16. I also have added a fan controller and custom cables.

How many cores are selected to be used in the Raytrace setting in preferences? I set it for about 28 to be used and that still allows me to use intensive programs like AI, Photoshop, ID etc. Are all of your cores enabled in Ryzen Master?

And just one more thing: The Ripper has a known issue with causing core temperature readings to be 5 degrees C higher than reality. Peace, Jon

Just one more thing: the Ripper likes all DIMM's filled up. Look it up. I noticed a significant difference when I filled all to 64total. I know it's expensive. Just a thought. Peace, Jon

Go with the Gskill. The timing is perfect for Ryzen, cas14. Look it up. I wish I got that kit, as it wasn't available when I built it. Did you get the Ripper for 7? I am thinking about building a second rig that is so cheap.

Hey Rosco, I called it first. Heat is not the issue. My quad kit is approved, there is a master list available on AMD's website. peace, Jon

Have you tried all the settings in-between? Try setting it around 2933

I just remembered that I had a similar issue at some point and I solved it with a BIOS update. Have you tried that yet?

And XMP 2.0 is enabled?

One more question: Are you making these changes in the Ryzen Master utility or in your mobo?

After re-reading your posting---it is most definitely your RAM. First, check to make sure that it is compatible with your motherboard (I think it is), then try to reseat the RAM and then run a PASSMARK or memory stress test. My winning combo was 64gb of CMD32GX4M4B3200C16 (quad channel), with the AsRock Taichi mobo.

Is your RAM maxing out right before crash? Or just CPU?

Did you have any issues installing Windows on the x399 system? Was it a "fresh" install?

Hi Rosco! I have a Threadripper system that is very similar to yours, that I built myself--so maybe I can help. A couple questions: Were you ever able to Raytrace with no problems? Have you run major burn-in tests and benchmarks? Are you running all 18 cores at time of Raytace? Are you opening the file and raytracing on the same drive? Have you tried swapping the motherboard yet? Where did you buy the parts? I actually had problems with the Aorus board and swapped it out for the AsRock, and I haven't had an issue since then. I think I have heard that the Aorus has problems with memory compatibility. An 850w PSU is right on the borderline of needing to be the next size up, with your hardware. I highly doubt this would be causing your issues. I am able to get my memory Corsair Dominator to clock to 2933 with the system absolutely loving it. The Threadripper is a Chief Render Ripper, in my opinion, I actually named my computer da Render Ripper Currently I have open a 90k square foot plan file and a Raytrace of about 10k square feet with too many lights to count, and I am writing this posting to you with no problems, sick! Hopefully, you can get yours there, I will do what I can to help. Peace, Jon

Thank you very much for the info, I did not think about shutting off auto-rebuild. I think that will make a very big difference in my performance. I just deleted all of the 3rd party objects from the library and it has solved the issue. I have a plan to have Sketchup running simultaneously to use as my library browser then import only the needed objects.

I was actually going to start my post much like that and say "I think I already know the answer to this question". I have looked at many of the postings about this subject, however my take away was that it was system limited, not software--but I could be wrong. I guess what I really should have asked is: What is Chief's posted limit of data loaded by the user before performance of Chief alone is effected? (if that made any sense

Hi Everyone! I forgot something else: If I close the library browser completely down within the viewing window, the performance is greatly improved. Peace, Jon

Hi Everyone! My largest single .skp file size is 65,000 KB, with the average being more like 20,000 KB. Peace, Jon

Hi Everyone! I am working on a 90k square foot remodeling project for Veterans' and up until this point I have had zero issues or lag from my hardware or the Chief Software. I recently imported over 375 3rd party 3D objects in order to accommodated the design requirements of the project. A majority of the objects are 2017 Sketchup (.skp) files from 3D Warehouse. Some of the objects can get very complex--such as entire Coffee shops, large 3d wall panels, large furniture groupings, and complex medical equipment. On some of the more complex and larger ones it took about 20-30 minutes to get the object to load into Chief. My file size is currently just over 3 GB and growing --- which is something my system can handle. As of right now it feels like I am using a POS computer, and I am most definitely not ( (see specs below). Just about every operation (in Chief) is very slow and bogged down--I can still use the rest of my computer fine. Have I overloaded the Chief Library / Software? If so, should I purge all unused objects until they are needed in order to improve performance? Is there something else that I can do? I truly appreciate your help. Peace, Jon Ryzen Threadripper 1950x (16 cores) 64 GB 3200mhz Quad Channel Ram Corsair Dominator Nvidia Quadro P4000 2x 512 GB Samsung 960 Pro M.2 SSD 256 Samsung 960 Evo M.2 SSD 2TB Samsung 960 Evo SSD Corsair 115i Watercooler Corsair HX1000i PSU

The guys a Puget do a lot of really good research, however I have noticed a company preference towards pushing Intel I7's. I told them a while back that I wanted a dual Xeon system because Chief rendering needs cores--and they disagreed with me and steered me towards the 7700k. I tried a 7700k system for about a week and it was woefully "under-powered" in my opinion. Although CPU speed definetly helps with most general functions, I feel that a fast GPU with an extremely fast SSD like the m.2 960 pro SSD, makes the greatest difference. I cannot believe how fast and reliable library navigation has become since I have started to use the 960 pro! Peace, Jon

Thanks, I think I am going to nickname it "da Chief Ripper". When I ran those tests I had the GPU running stock and the CPU was actually only OC to 3.6. I just got detailed instructions last night on how to safely OC to 4.1 with my current equipment. Also, I am going today to replace the memory with a 3600 quad kit instead of the 2666 that I currently have which is throttling me back a little bit. Currently it is only scoring in the 60th percentile of other threadripper systems. People have been cryo cooling the threadripper and getting 5.1! The huge huge upside that I am noticing is that I can continue to work on my computer, even inside Chief, while the Raytrace is running as the Threadripper allocates at least one core for system processes and you can allocate more. I could never do this on a quad core or even the 1800x Ryzen that I tried for a little bit. I am sure the Xeons can do the same however, the Threadripper is considerably cheaper than dual Xeons that are benchmarked at the same level of the Threadripper. I built the system myself with part from Microcenter after much research. I spent days dealing with "phantom" motherboard issues with unknown solutions as the motherboard and processor are on the bleeding edge as they were just released at the beginning of August. I have attached my shopping cart from Microcenter--they no longer have my motherboard in stock so I had to substitute it with something else. Peace, Jon

I am just trying to compare my system on Chief as I built this system by hand almost entirely for Chief, and some Revit. Peace, Jon
