PC Build for Octane

Recommended Posts

Hi,

So long story short. I bought an Imac (stupid move) now I'm going to sell and finally move to the dark side. Last time I used a PC was 10 years ago. Looking for a build which initially will have one GPU and then in a few months allow me to add a second. I'll be using Octane render for C4D.

I'm totally useless with part picking but a guy at work is looking at doing the same thing. Is there anything in this list that isn't going to be good?

Also if anyone has an opinion of the Del Ultrasharp 27 that would be great

I'm sure everyone has there own variation here and there but I'm really just making sure that if i buy these parts I'm not going to regret it!

Thanks in advance!

I've got a 27in DELL Ultrasharp. Very happy with it. For the price it has great colour accuracy.

 

For the PC/Octane build, have a look through this forum page: (you might have to dig through a few pages to find the build threads)

There are a few guys there that are experienced in building custom Octane machines.

Decent start. I would go with a video card with a reference cooler so you can stack more together. You can get away with 4x980ti with reference coolers, but using those open type coolers like that one won't let you do that without significant thermal throttling. That PSU won't be good for more than 2 video cards. I'm not familiar with that motherboard, so just make sure the performance of the PCI slots will keep up with a 4x980ti setup. Even if you don't want to spend the cash on multiple GPUs right now, make sure the rest of the system is up to spec when you need the speed later on.

 

For my home rig I'm building this week, I've opted for a max of 2 GPUs in favor of space/portability. Here is the part list.

The processor is unlocked and judging from the watercooling, he may intend to overclock. If this 5820k is anything like the past i7 chips, it should be able to hit 4.0+ghz easily.

Thanks all for the replies.

 

For anyone interested this is my current build spec.

I got some advice from Tom Glimps at the Otoy forums - he seems to be one of the most clued up guys out there on building for Octane use. I'm waiting for him to hopefully give this new list a look over.

I think what's changed since I first started looking was that he advised to get a CPU with 40 lanes and a reference cooler designed 980ti so the heat blows out of the case, not inside. So the CPU is a bit more powerful too and cost a little bit extra but worth it long term.

 

There's a couple of other things that haven't changed such as motherboard but thats mainly due to my lack of understanding in what i need and card spacing etc.

 

If anyone is interested this is the current thread on ten Otoy forums:

https://render.otoy.com/forum/viewtopic.php?f=25&t=50158

 

I'm still pretty confused by all this. In particular the motherboard requirement and I've been told that the case I was looking at is huge. Not really sure what to replace it with. I do know that cooling and airflow is essential to get the best from the video cards.

I'm also pretty maxed out on affordability know so hopefully this ends up being 'the one' ;)

 

Thanks again for input and anything else you want to add is appreciated.

I would agree. If you want to ever run 4 GPUs, you need to do the 5830k for 40 lanes. You will see benefits with just 2 GPUs. The CPU is basically as fast as the 5820k. You are mainly paying for extra lanes.

 

The Air540 is a good case. It should cool this kind of build just fine with the right fans. We have built 4xTitan builds in the Corsair 760T and 780T cases that have been great. The Air540 is smaller, but wider than those cases. Basically you could just decide on looks which of those 3 cases you like best.

 

I only have experience with EVGA and Asus motherboards, so I can't say anything about the MSI. The Asus x99 WS board is the only one on the market that can give 4 x 16x PCI slots. That being said, I haven't noticed any real difference in octane between the computer with the Asus and the EGVA that doesn't.

 

I finished my mATX build this weekend, and with one click I got the 5820k running at about 4.1ghz. I haven't had time to tweak it further, but it still got a cinebench 15 score of over 1200.
