Ryzen 7 3800X with RAM ???? MHz

[EXTRADODO]

I'm going all out on Ryzen 7 3800X base on my researching for the use of ARCHICAD (Graphisoft), REVIT (Autodesk) and other stuffs like Chrome, Mail, Skype, etc...

I have RTX 2080 Ti, 2080 Super, 2080 and Radeon RX 5700XT at the moment. I'm not sure what to use but will be using something good enough for it.

 

What I'm not sure is, what DDR 4 RAM should I use? I've used 3200MHz 8GBx2 before and it feels nice but I want more speed.

Can I use some faster and crazy RAM like 4000MHz or higher? Is it possible with Ryzen 7 3800X? 

 

If so, what Motherboard will I be needed?

 

The main purpose is the speed for windows booting time, CAD app booting time / data loading time, etc...

The budget is unlimited. Shoot .....

 

CPU : Ryzen 7 3800X (or it can be Ryzen 9 3900X but I'm not sure CAD app would benefit much from more core)

SSD : Samsung 970 Evo Plus 1TB (I know this's not the fastest boy but I've already bought it)

GPU : *Something near the desk*

RAM : *PLEASE Suggest*

Motherboard : *PLEASE Suggest*

PSU : *Gonna overkill this one*

CPU Cooler : Corsair H100i / H150i Pro

 

Oh lord... this gives me anxiety

Didn't you just post about this before?

 

Get some 3600MHz RAM.  4000MHz isn't guaranteed to work.

Yes, I did. But I didn't put into thinking about RAM and Motherboard at that time.

Good to hear. I'm sure InfinityFibric*** (not sure what it's called) speed need to be 1:1 to that too, right?
 

I'll look for OC for those in LTT videos. Thanks you @jstudrawa

Stay below 3700mhz in Infinity Fabric 1:1. Once you enter Infinity Fabric 2:1, you will need to get your ram speed to 4400mhz to compensate 2:1 latency.

[Firewrath9]

Why do you have so many GPUs?

Spoiler

feel free to send me a couple (/s, but not really)

 

I'd recommend getting 2x8 DDR4-3600, overclocking to 3866, and tightening timings. 1933 on IF or 3866 memoryis the highest you can go on a 1:1 ratio. You can get 3866mhz/16-16-16-36 on this kit pretty easily. It's b-die and binned, and has a massive heatsink

If you want to have even tighter timings, (think 14-14-14-34 or even less) the 4300mhz is only 50$ more.

Zen 2 infinity fabric (or IF) clocks up to 1800mhz or 3600 RAM in normal mode, and 1933/3866 in OC mode. Any higher and it switches to 2:1, which would mean your RAM has to be ~7000mhz to have the same performance.

[EXTRADODO]

@OlympicAssEater Nice name. I have to look twice before mentioning you.

And thank you for the ratio info. I'm gonna save that image too.

 

Sorry for asking super stupid question but is it the higher the RAM speed, the faster it gets?(4400MHz faster than 3200MHz in real life use?)

*I know this is stupid but this is like "6+5=11? gotta check with the calculator" state.*

 

Btw, what Motherboard do you recommand if I were to go with 16GBx2 of 3600MHz RAM ? 

 

[amdorintel]

3600 is the sweet spot, anything much higher then that then you are asking for glitches

Get as fast RAM with as tight timings as you can get (but reasonable), e.g. there are nice 4000-4500MHz kits available for good price from Patriot and Team Group.

First, even if Zen2 now is limited to about 3600-3800 MHz 1:1 MemCLK:FCLK speeds, it may change with Zen2+ (or how will they call it), which will be AM4, too. And you will be able to use the same memory.

Second, you always can run a fast kit at slower speed with tighter timings.

Third, price for the good 3600-3800 MHz kits is high already, there is not a big difference to add for a 4000-4500 MHz kit

Just IMHO.

[EXTRADODO]

@Firewrath9 Thank you. I'm going with 3600MHz (or OC it a bit). 

@amdorintel Hi again. I'm sure I'll play safe with this built.

[Firewrath9]

Oh, as for Mobo recommendations, The Aorus X570 Pro at ~250$ is good, and if you have a little more cash, at 300$, the MSI Unify is good, or the X570 Taichi. At 350$, its a throwup between the X570 Master and the X570 Crosshair 8 Hero. (I'd take the master). Any more is a waste of money, unless you need 10gbe.

Yeah, I'm gonna go with a safe-for-now build with this one. I'm sure there'll be much faster hardware in next year.

Alright, I'm going with 3600MHz. Any suggestions for the Motherboard? @1van

[1van]

@ZWELINHTETBasically, the boards that @Firewrath9 recommended, depending on prices/availability/brand preference. I read Gigabyte made many good X570 boards this time.

As far as I know, CAD software eats as much cores/RAM size as you can give it, so I'd either saved some money with 3700X instead of 3800X, or added to 3900X-3950X. 3800X doesn't make much sense.

Thank you @Firewrath9. I'm going with Aorus X570 Pro which costs 30,000 yen here. I think the price is good enough.

I thought of that too. But the base clock is something of a main subject for software like ArchiCAD and Revit. They use more than once core but not at all time. I've tested with xeon gold, core i9-9900K, core i7 8th gen, Ryzen 5 3600X. The results are almost the same here. That's why I want to go with Ryzen 7 3800X with a bit of base clock and a bit nice multithreads. The price difference is not a problem in this case as my budget is allowed for unlimited.

Why not 3900/3950X then? Or even wait for a new Threadripper?)

There's no stock for 3900X that I can buy within 3 days in Japan and there is no 3950X yet in this island country.

The only limit here is the Time and I don't have much left. I wish I can get those boys on my hand.

@Firewrath9  Which one do you prefer for CPU Cooler "Corsair H100i or H150i" ?

If your case fits the H150i, then get that one. It's bigger but better.

[EXTRADODO]

@Firewrath9 Thank you.

To everyone sharing knowledge and ideas to me through this weekend, THANK YOU SO MUCH. 

 

This is what I'm going with this build. Feel free to judge my poor decisions. Love you all

@ZWELINHTET

3 objections at least:

1. The card you've picked is a reference design (bad and noisy cooling). If you want to install a full-cover waterblock on it - then the reference is the best choice. Otherwise, pick Sapphire Nitro, PowerColor Red Devil, Gigabyte 3-fan model, or MSI Gaming X;
2. Water cooling for Zen 2 is not necessary, the heat dissipation of the CPU is considerably lower than 200W, meaning any good air cooler can cool it. The high temps of Zen 2 are due to the small-area 7nm chiplet which can't pass it's heat to the heatspreader fast enough;
3. GPU again, since you're going to use it for production, confirm if your software is better accelerated by OpenCL, CUDA, or even tensor cores of RTX cards? I've read some companies have added the support already.
