I am thinking about pre-ordering the 1950x TR cpu.

The mobos aren't on PCpartpicker quite yet but I think the rest of this will be compatible with the chip set. My goal is to upgrade this machine later and just not spend all the money up front. Later I'll add the other GPU, get a sound card, expand the ram if 32GB somehow isn't enough one day. I've also got another 500GB SSD I am going to add to it when I do the build. Most of you know way more than I do, what are your thoughts?

Gaming, content creation, VR are the main uses.

Solution
You are wasting 1/2 the memory bandwidth by only have two DIMMs. There is no way to know if the Arctic CPU cooler will work on TR4 sockets.

I thought I read something that said the Arctic 120, 240, and 360 were expected to work with it. I think the obvious answer is to not to pre-order and let someone try it all first :)

Also, good call on the memory, I'm an idiot. I'll just get 32GB(4x8) and if that's ever not enough, I'll move that Ram to a pure gaming computer.

As I'm looking into building a new Rysen system as well, one thing I've found in RAM is that they are similar to floor tiles in that you want to get sets of RAM from the same batch - that is really the only way they can be guaranteed compatible, especially when overclocking. If you get them from different batches (say 32g isn't enough) then you would want to by a 64g kit. Tiles are the same way, they can have subtly different colors (found that out the hard way).

Do you think it's important to get all 8 DIMMS filled? Lets say I want 32GB of ram....I'd be tempted to get 4x8GB so I could later expand to 64GB but are you sacraficing performance of the ram to only fill 4 of the spots instead of filling all 8 slots? If to maximize performance I'm supposed to fill all 8 slots I'd probably just grab a 8x8 set.

With threadripper, I would get a matched set of four 8GB DIMMs. I would wait a while to let the BIOS updates have a chance to get to the community. Hopefully AMD has learned a few things with the memory instability that Ryzen had. I have purposefully waited to purchase a Ryzen build to allow BIOS updates to get out.

Threadripper is a completely different ballgame than a regular Ryzen setup is. You're talking about a $1,000 CPU vs a $300 one, and the environment that it will need to run under will need a lot more horsepower backing it in order to function properly. It's not so much having the same RAM, it's the RAM *SPEED* you need to worry about.

Couple thoughts, since I'm working on a very similar build myself and have been doing some after work hours research here and there.

I like the Arctic cooler choice and was considering the same, but have recently switched it to the Fractal Celsius S36 unit. This unit is the same price as the Arctic, offers roughly the same performance, has the same compatibility with TR(Asetek head), even has the same clearance specs...though the fractal unit only comes with 3 fans rather than 6. The reason I like the Fractal better though is because it's upgradable whereas the Arctic product is not. Just a suggestion, and if you're 100% certain you'll never need more cooling then ignore it and stick with what you have.

Also, I'd try to swing 4x16GB memory now if you can budget for it. Reason being that you then won't have to deal with filling all your ram slots later or re-selling the 4x8GB kits. Also, though 4x16GB is likely to result in slightly lower memory clocks, dual rank memory does outperform single rank dims...with a delta of around 300Mhz. There are a few cost effective 4x16GB g.skill kits floating around that perform well...at least with Ryzen. F4-3200C16Q-64GTZK comes to mind. I believe those are Hynix ICs and not the optimal Samsung chips, but the Sammy chips cost a bit more(+25% or so). Mind you, this is all based on other people's research, but both kits seem to perform well on Ryzen so you won't get a total stinker either way.

I believe you can ensure Samsung chips if you pay attention to secondary timings on those same part number g.skill kits.

DDR4 3200 (PC4 25600) Timing 16-18-18-38 = Hynix...like the ones on sale linked above.

DDR4 3200 (PC4 25600) Timing 16-16-16-36 = Samsung...I think.

If I were ordering all my parts right this second, the memory I'd select would be 2 of these kits:

What are you planning to do with the system btw? Is another 32GB of ram a crucial element?

Thanks so much for your input, I think that's an interesting thought about the cooling system. A lot of people have suggested the NZXT Kraken X62, probably because it's been announced as compatible with TR. I've never built a computer with a liquid cooling system, I've watched a bunch of youtube and still don't really get it but I'm not afraid to try it. What are your thoughts on the X62 compared with the Fractal idea?

That's good info about the RAM I'll be honest I didn't know that about the Sammy memory!

There's a million coolers you can get that are way better than anything Arctic makes. I'd go with the Kraken X62 as well since it is one of the few that's compatible with the TR4 socket, but there will also be better coolers available once the CPUs start rolling out.

To be clear, I'm not crazy about any of the Asetek compatible AIO designs, particularly for Threadripper. They don't provide full coverage for the dies, their best point of cooling is the center of the IHS(where there's nothing but space), and they may not be up to the task. That being said, if I had to choose a cooler for Threadripper right this second it'd definitely be the Fractal S36 unit mentioned previously. While it has the same problems as all the other Asetek based non-threadripper optimized cooling solutions, that one is relatively cheap and somewhat expandable(the connections at the radiator). It's the weak pumps and non-optimal block coverage that's the problem with all these AIOs, so a unit that lets you dispose of the head seems like a no-brainer to me, but ymmv. My own build will have a custom loop, so I'm stuck waiting for a compatible waterblock.



Very nice! Keep up posted on how it goes. Love the case choice as I chose the Enthoo Pro for my threadripper build. The roof of that sucker is going to be filled with a 420mm radiator. :)
