Question Best motherboard for housing both 3080 or 3090

[jinkazuya]

I am just wondering what the best motherboard is to house two 3080 or two 3090? I am also looking for the one that support the latest intel processor 13th or 14th. I am doing rendering y the way. Thanks. Because I cannot figure out with the two slots are spaced out with enough room that will accommodate two cards.

A lot of that depends on the size of the cards. If they are 3+ slots, very few boards out there to accommodate that. Founder's editions would work pretty well though.

There are very few 13th/14th gen boards that are intended for dual GPUs these days. Do you need SLI to function? Only the 3090 and 3090 Ti support that, the 3080 will not. None of the 40 series do either.

I will see if I can find one, not really something they go out of their way to advertise any longer.

The old MSI MEG looks pretty decent, not too expensive either.

These are some available 3090 that are narrower. The FTW3 are cheaper and better, but much bulkier cards.

Obviously going to need a massive power supply to go with this and you should seek out a chassis with at least 8 PCIe expansion slots so you have a little extra room.

Someone did it with two FE cards. https://pcpartpicker.com/b/3zzNnQ

MSI Gaming GeForce RTX 3080 Ventus 3X Plus

Mine are the above. I do rendering and other stuff since the apps or the software that I use support dual graphic cards running simultaneously. That is why I would like to have two cards. I havd had two 3080 already and two 3090 but preferrably 3080 two cards.

This is the case I have
Cooler Master HAF 700 EVO E-ATX

That should still work then.

So brother you meant that with the motherboard you listed, the dual 3080 will be supported? Can I use this one instead https://www.msi.com/Motherboard/MPG-Z690-CARBON-WIFI/Specification?

 

[Eximo]

Yep, that would work too. The key is to have 3-slot spacing and CPU connected PCIe lanes are preferred.

I will point out that board does not support SLI, but the MEG does. So if you ever wanted to do get dual 3090 and do something with NVLink, you wouldn't be able to with that board. But as I said, newer cards don't support it at all.

• PCI_E1 & PCI_E2 slots (From CPU)
  • Support PCIe 5.0
  • Support x16/ x0, x8/ x8
