Building a new Pc with AMD Threadripper - Vegas Rendering Speed?

Hey everyone.

I am new to the community here, but I have been a Vegas user since version 8. I have a small project studio that is based off a custom PC I built which you can see details on here:

I have the new AMD Threadripper CPU going into this build (hopefully I can put it together tomorrow) when AIO water cooler for the CPU gets here. The CPU is a 16 core 32 thread processor. Does anyone with advance tech knowledge about Vegas know anything about how it scales across multiple threads/cores? I am currently using the Intel 6800k 6 core cpu. Just wondering if I will see a dramatic increase in rendering times or if Vegas will be limited on how well it will scale across the cpu cores.

Thanks for any replies!

I will be interested to see what sort of results you get. There is a thread on the main Vegas video page where a fellow is seeing very low utilization on a 24 core Xeon CPU. I have very little hope for the supposed upgrades coming for GPU and QuickSync support to improve performance, and have myself been considering going for a CPU with many threads. I do suspect there are age old bottlenecks in Vegas that may hold it up. However, tweaking the hidden preferences menu settings might help. It is plain crazy that multicore users need to tweak off-label settings in order to get the application to even consider taking advantage of available cores and threads.

Hey Robert,

Thanks for the reply! I too am hoping this, as I am right now on my new Threadripper build. A couple Hiccups along the way, but mostly driver related. I am hopeful that Magix will take Vegas 15 and do a lot of different with it, since 14 was so close to their purchase from Sony, but who knows.

I did a rendering test with Threadripper last night. First render, I got a blue screen of death about 20 minutes into it. Could be a million things that caused it, as the stop code didn't give me much info. I guess that is where my next question comes in.

I have 32 gigs of ram installed. I don't know a lot of Vegas inside settings the way i should, as I am an enthusiast/hobbyst more then anything, and my projects are noo to complex. But I had the Dynamic Ram preview ram setting up a little high, and I was wondering if it is possible that could of caused a BSOD error. I think out of my 32gigs of ram, I had the dynamic preview inb the settings at 28gb or 29gb of ram. After the crash i pulled that down to 16, and it got through the render, but it added about 10 minuets to the completed time.

I have no tested my new ram sticks yet, and I have XMP profile on at the moment, and my motherboard's company (Gigabyte) is suggesting I turn the XMP off for now until I can see more stable sessions. I only got to do one render last night, and it completed after the bsod, but I cut the ram allownce to 16gb, AND did a video card driver update (gtx 1080 8gb card).

I'm using an AMD FX-8300 plus NVIDIA GeForce GTX750. Is this suitable for Vegas 14?

@Liberty610
As far as I am aware BSOD tend to be down to driver/hardware issues rather than software. I don't think it is impossible for a piece of software to make a call that triggers the BSOD in a driver, but the protected memory nature of modern operating systems make it unlikely that the software itself will cause such a critical system wide fault. It might be worth doing a memory test on machine. Video rendering being a high demand application it is not impossible that it might be showing up a fault that is not apparent under normal use.
