[SOLVED] MINI ITX motherboard for the Ryzen 9 3900X CPU

[Ragahv]

Hello i am looking for the best cheapest motherboard for the AMD Ryzen 3900x CPU with support up to 192 GB or more DDR4 RAM up to 2400MHz.

I actually have 6 32GB non ecc unbuffered ram lying in my house using on my UD4 Pro X299 Motherboard. Will the ram used on that board work on my new AMD board or is AMD and INTEL having specific ram from each other?

Actually all my RAM is total to 192GB. All ram sticks are non ecc. All modules are 32GB each and i have 6 of them. So on a mini STX or ITX board, there are usually 4-6 slots. Any mini STX or ITX boards with 6 slots?

Also i wanna use sapphire mini GPU with 4GB or more vram on my mini stx or mini itx board. However i wanna SLI them but using AMD link version of SLI i think its called cross over.

I need mini STX or ITX board with at least 3-4 PCI-E Slots and if you cant find me a mini itx board with that many slots, i will go for a larger form factor. My intention is not only AAA 4K gaming but it's also virtualization. Such as run multiple instances of server 2019 data center r2 in vmware workstation for work purpose. I thought 3900x cpu would be perfect for that. I need the board to support 3900x cpu and above so like 3050x, 3060x, etc... The board must be pretty expensive. My budget for board is $500.00 max. If the board is expensive then all i need is the above said and support for 128GB of ram not 192GB. However im looking to spend only 500 AUD on the board and no above. I only need 3900x cpu compatible board then and PCI-E slots must be 4 or more on board.

Ok lots to unpack

Cheap and itx don't go together, not to mention spending 400+ USD on a CPU to put it on a mobo that has bad components is just silly. I believe all ITX mobos only support either 32GB or 64GB. This is about the cheapest it gets

As far as using old RAM yes it should work but RAM slower then 3200 (3600mhz preferably) has a pretty big performance hit for Ryzen.

AMD no long supports Crossfire with their new GPUs and Nvidia SLI is more or less a dying technology due to it poor scaling and lack of game developer investment. Its almost always recommended to just buy a single more powerful card then doing multiple GPU setups.

I dont think there is any ITX board with more then one PCIe slot. If you want that you will need to go with a mATX board which usually have one PCIe3 x16, a PCIe2 x16 and one or sometimes two PCIe2 x1 slots.



If you want to run multiple game servers it would be cheaper to buy a used server or buy a used Xeon or 1st Gen Ryzen and build a cheap server around that. Then have your gaming computer separately.
