New computer build questions

I'm building a system around a Threadripper 1900x, GTX 1080 8GB, and either 32GB or 64GB DDR4 3000MHz, with Asrock TaiChi X399 motherboard. Blackmagic Decklink 4k mini monitor.

Does this seem acceptable build to work with 4K files with several nodes on a 4K timeline?
I will be working with RED 4k and other video formats.

Should I consider upgrading to the 1080 "TI" version?
Will 32GB RAM 3000MHz be okay?

To me, it's underpowered for 4K. One 1080 will not be enough for real-time noise reduction, or other GPU OFX on a 4K timeline.

Threadripper 2 processors are supposed to launch August 13th, so I would wait to buy/build until then anyway. I would also spend more money and go up to 16 cores.

32GB RAM should be fine.

Hi.

All AMD CPU's really benefits of faster RAM. 3000 MHz is below recommendation in the Resolve 15 Configuration guide where 3400 MHz is recommended.
Together with Threadripper 2 with be introduced a new AIR Cooler recommended for both for both Threadripper 1 or 2.

Ok thanks. I don't play the waiting game, as technology rapidly changes, can't keep up with it. Threadripper2 may be $1000+, which is out of range for me, until I can get established with a lot of projects coming in. All tests I saw with a 1080 show you can put several blur nodes on it and it had no issue with slowdowns. So I'm a little confused when people say a regular GTX 1080 is too slow for 4k. I may just have to try it and see how it performs for myself.

In the HW config guide, the regular GTX 1080 is listed as recommended.
3400MHz is the clock speed of the 1950X TR CPU. Not the memory. Memory is timed seperately from the CPU speed. And Blackmagic doesnt list any specific memory speed in the guide. Unless I missed it.

No reason at all to go with a 1900x over the 2700x, unless you need a space heater in your computer room.

2700x is on par or faster. The only gain is PCI-e channels. If you are going with a single video card (1080ti), then this isn't a factor. And you don't have to get 4 sticks of RAM because of quad channel.

The only thing I would do to my PC is up the GPU. I replaced the stock cooler with an NH-D15, but I only gained a few degrees C. I have run some serious re-encoding with my 2700x running all 8 cores and 16 threads 100% for 2 days. CPU never got up to 70C.

Get a good x470 board. Get a 2700x. Get FAST memory. Ryzen is more memory speed than Intel. Save the complexity of a Threadripper and have better performance.

If you want Threadripper, wait until those also go Zen+.

I considered 2700x, but there are just too many limitations. I wanted 3 nvme, plus more pci-e lanes, since I am adding multiple Pci-e cards. I will eventually add 2nd GPU. To be honest, any new computer will be a lot more faster then my current system. And before 1080TI came out, people were using 1080 just fine with Resolve in realtime.

TNR or GPU OFX are not happening in real time on a single 1080 using 4K media. Simple grades will work fine. I find the old candle blur nodes metric pretty useless, as it's not representative of what people actually do in Resolve.

I encourage you to wait a little longer, if you can, before buying a new system. At this point, the GTX 1080 is more than 2 years old, and the Threadripper 1900x is just under a year old. Threadripper 2 processors come out in less than a month, and it is widely suspected that the GTX 1180 will also launch in August. It's understandable that you may not be particularly interested in the hardware, but if you can't afford top of the line hardware, you can't afford not to buy smart.

Thank you all for the advice. Unfortunately I cant wait any longer as I have been given a project by someone to work on. And that needs to be completed in a couple weeks at maximum. So I need to get something built here this weekend. When TR2 comes out, I'll just sell my current parts again if I can

I would build for 2700x. If threadrippers get to a decent price with Zen+, you can sell MB and processor and upgrade. The only reason for a TR build right now is for the 1950. Also, even if the same x399 motherboard will work with Zen+ TR processors, they will more likely work better with the newer (probably x499) MBs.

OK I may sell my 1900x I just bought and buy the 1950x with gtx 1080 ti. TR2 will be crazy high price for at least a year or more. They expect the 2990x to be $1700 USD. That is a lot more then any current TR cpu.

So even the GTX 1080 is more powerful then the AMD 580 they put in the Apple BMD external GPU. So I dont think I can go wrong with just the regular 1080 for now.

If you already have the 1900x, no reason not to build it and try it. The price up to the 1950x is pretty big and that might be better to save until the Zen+ TR comes out and drives the price down. I had assumed you had no parts yet.

Also you might look at the 1070ti. Many see that as overclockable and equivalent to the 1080.

In the HW config guide
3400MHz is the clock speed of the 1950X TR CPU. Not the memory. Memory is timed seperately from the CPU speed. And Blackmagic doesnt list any specific memory speed in the guide. Unless I missed it.

Hi.

In the HW config guide on page on page 36 is the RAM Speed listet:

'DDR4-3200 SDRAM minimum'

The only problem is on the QVL of the motherboards I'm looking for, most 3200 DIMMs only run at 2933. Hard to find ram that is supported at higher speeds with more then two DIMMs. I am going thru the QVL of two motherboards now and going to try to make a decision tonight. Thanks.

Also on the QVL it's hard to find supported memory that you can install 64gn or more. A lot of modules on asrock and gigabyte QVL are limited to two or four 8gb DIMMs for 32gn total. Some 16gb DIMMs are limited to two only. Ridiculous.

Hello everyone!

I have Decklink Duo 2 capture card and want to build new PC around it.
Also I have Nvidea GTX 1070 and wanna use it in the system
And it will work on Windows 10 Pro 64 bit with Wirecast 9

I'm free to choose any core, motherboard and memory. And I feel a little bit confused cause I can't find any up-to-date recommendations about compatible motherboards
All what I find is this list: blackmagicdesign.com/support/note/9568
But there a lot of out of date models wich support only 4-5 generation Intell Cores.
And only one motherboard compatible with 7th Core generation but it out of stock.

Have anyone built similar PC computer? Wich motherboard did you use?

Thank you in advance,
Dmitry

How do you propose to run this speed, if the official speed for Threadripper is DDR4-2667 and a lot of boards don't support 64GB running at 3200Mhz?

Both the Gigabyte X399 board, and Asrock QVL shows that if you install any 16GB DIMMs 3200MHz, the speed is only guaranteed to run at 2933MHz. And there is one Gskill 16GB DIMMs that do run at 3200MHz, but you can only have up to 32GB total. Anything over that amount is not guaranteed to run.

So I think I'd rather go with the 3000MHz DIMMs where I know I can install 64GB total and run them at 2933MHz stable.

So I ended up ordering:

Asrock Taichi X399
CORSAIR Vengeance LPX 32GB (2 x 16GB) DDR4 SDRAM 3200MHz
Crucial MX500 M.2 2280 500GB (For OS)
EVGA GeForce GTX 1080 Ti SC2 GAMING
Threadripper 1900X
BlackMagic mini monitor 4K

I may still swap out the 1900X for 1950X and also order another 32GB DIMMs for 64GB total in the future to go quad channel.

Hi.

I was just writing an answer to your previous post, as I now read that you have ordered.

From my first post: Suggest you ask your computer dealer, he must know which of his DDR4 Ram that will be best for one of his Threadripper motherboards.

And my comments to you order. I can not recommend to only use dual ram. Threadripper is designed for quad channel DDR4 Ram.

I have never seen a good review of Threadripper 1900X. Only 12 core 1920X and the 16 core 1950X. If you need to save money look at the 1920X.

Regards Carsten.

I understand TR is designed for Quad DDR4. All tests I've seen though look good for my needs with dual, and I can always purchase another two matching DIMMs for quad channel. I'm just trying to get my film reel finished, which will be 1080p for now and have only one project given in 4k to work on. This config will certainly be much faster then my current system. People use Mac Pro laptops which are much less powerful and don't even have dedicated GPU.

It will work with dual. The Treadripper is essentially two Ryzen chips glues together. So your 1900 is two Ryzen 5 1500 chips. With two DIMMs it works, but is just like running a desktop processor single channel rather than dual. If I recall correctly, the penalty was around 20% for dual vs quad on the TR. It will be noticeable. However, if you don't have the money for the full RAM size you want now. It might be prudent to go this route as the RAM prices (hopefully) drop.

Make sure to update your RAM speed in the BIOS, as sometimes it is lowest setting for compatibility on the AM4 platform at least.

I like to run http://cpu.userbenchmark.com/ software after a build. If my hardware is performing much lower than average, I probably have a setting wrong.

I went ahead and ordered an extra 2x16GB DDR4-3200, so I'll have quad channel and 64GB total now. We will see if the board actually runs all four DIMM's at that speed stable.

Looks like my board and a few others will support Threadripper 2 when it comes out.

Hi.

Most of the information we know about Threadripper 2 was told by AMD at the Computex 2018 Tradeshow. They told that the socket is the same and that they can share motherboard with Threadripper 1.

But the also told us that the TDP of Threadripper 2 will be 250 Watt. It is only 180 Watt for Threadripper 1.
So I will expect it will depend on the number of VRM's. So if you have a motherboard for Threadripper 1 with many VRM's and therefore is good for overclocking will I expect it will be better for Threadripper 2 with a TCP of 250 Watt.
