first pc build

[NERDMONSTER9000]

Hello, I’m new to building pc but I would like to build an amazing banger of a machine. The only issue that I’m having is which RAM I should use as well as the motherboard. 
While PCPARTPICKER.COM may list both RAMS as compatible with either motherboards and 64 core Threadripper CPU it tells me that the modules may run at a reduce clock rate to meet the recommended max CPU voltage. Please give me some advice or help.

https://pcpartpicker.com/list/zVyKF8 <- My pcpartpicker system builder link.

 

“The G.Skill Trident Z Royal 64 GB (2 x 32 GB) DDR4-4266 CL19 Memory operating voltage of 1.5 V exceeds the AMD Zen 2 CPU recommended maximum of 1350 mv+7% (1444.5 mv). This memory module may run at a reduced clock rate to meet the 1350 mv voltage recommendation, or may require running at a voltage greater than the AMD recommended maximum.”

 

RAM OPTION #1: G.Skill Trident Z Royal 64 GB (2 x 32 GB) DDR4-4000 CL18 Memory (BOTH GOLD AND SILVER kits.)

 

RAM OPTION #2: G.Skill Trident Z Royal 64 GB (2 x 32 GB) DDR4-4266 CL19 Memory (BOTH GOLD AND SILVER kits) 

 

MOTHERBOARD OPTION #1: Gigabyte TRX40 DESIGNARE XL ATX sTRX4 Motherboard

 

MOTHERBOARD OPTION #2: Gigabyte TRX40 AORUS XTREME XL ATX sTRX4 Motherboard

 

Both motherboards are XL ATX and compatible with AMD Threadripper CPUs

THANKS IN ADVANCE.

What's the usecase?

Threadripper supports quadchannel so you look for a quad or octa kit with >3200 MT/s

 

You don't need a 2000w PSU. The system should run perfectly fine on half of that https://pcpartpicker.com/product/nQJkcf/corsair-hx-platinum-1000w-80-platinum-certified-fully-modular-atx-power-supply-cp-9020139-na

I mean, any of the RAM kits and/or motherboards should be fine. That warning PCPartPicker gives you just means it might not run as fast as advertised by default.

 

You have four different 2x32GB (64GB) RAM kits in your build; I'm assuming you want 256GB of RAM. In that case, it's better to pick a single 8x32GB kit (or four of the same 2x32GB kits).

You also definitely don't really need a 800$ 2,000W PSU; there are pretty good quality 1,600W PSUs for 450$.

There's also a warning that says that the first firmware versions of the motherboard don't support the 3990X; most likely, it'll come with a version that supports it. If for some reason it doesn't, you can always just take it to a tech shop and get them to upgrade it for you
