Hi Coronauts,

I am trying to build a new Ryzen workstation, but with mATX chassis for mobility purpose (because I am currently working outside of my country, so there is a chance I will move to another).

I have been searching for quite a while about this, that I need a mATX motherboard with 128GB RAM, but no satisfying answer found.
I am planning to use a B450 motherboard (ASUS TUF Gaming B450) with Ryzen 3700x.

I know that mATX board only has 4 slot of RAM, so I would need to find a 32gb modules, which is still very rare.
And I read somewhere here that Ryzen best works with 3200 Ram speed at max 64GB.

But what do you guys think about this one? Any thought? https://www.youtube.com/watch?v=lGHk3AQmQbI&t=420s

(PS: I noticed the price is 500$ each)

I was thinking of doing the same for different reasons. Only because 3700x works with two memory channels.
If you can, you have no real reason to populate all 4 slots immediately. So I was thinking going with 2 sticks now and 2 sticks later.

And they were a lot cheaper for example: CORSAIR Vengeance LPX 64GB (2 x 32GB) 288-Pin PC RAM DDR4 3200 (PC4 25600) Desktop Memory Model CMK64GX4M2E3200C16 - Newegg.com

Hi,

  • “double capacity DIMMs” that were sold by G.Skill and ZADAC in 2018 are special case that only work on Z390 ASUS boards, nowhere else.
  • For Ryzen you have to buy regular 32GB DIMMs. There are only few of those sold by Corsair and G.Skill right now.

I run Corsair 4x32GB 3200 CL 16 on Asus Strix-E X570 & 3950X build. It will also work on B450 & 3700X but might not be stable at 3200 CL16. I would not stress about it…so what,you will run it at 2933 or 2800 you will not lose any performance in Corona with this generation.

Wow I didn’t know that it is a different kind of DIMM, because it is just the only 32GB modules available in my country. I am gonna have to import the RAM then. :smiley:

Thanks a lot Juraj!

Hi, there are a few small form factor travel friendly cases that support a full size atx board, which would allow you to use a threadripper or intel HEDT platform to get more ram slots, and not have to use double stacked ram.

See this case for example:
