Questionneed help for dual gpu
Hey everyone,
I’m trying to figure out if I can use two GPUs with this MSI MAG Z790 TOMAHAWK MAX WIFI board. The first GPU slot is x16 @ x4, and I’m curious about adding another RTX 4070 TI in the second slot. Also, I need a case that supports dual GPUs, and since the second slot is at the bottom, I’m wondering if something like the NZXT H6 Flow Compact Dual Chamber would work. Any advice or tips would be really helpful!
It should function properly. You may need to experiment to ensure the right video card is selected at startup.
Unless you have a unique application that can utilize both graphics cards, this might not be worthwhile.
From what I observe, if the correct motherboard is used, the first PCIe slot has 5x16 and the bottom slot has 4x4. This setup seems sufficient for a 4070, though it really depends on how the software interacts with the card.
I was looking into the performance drop of PCIe4 x4 around 5-8%, which seems fine for me. I'm curious if there are any suitable cases that can accommodate an additional GPU on this motherboard.
There's nothing that should prevent it from working like you want. If you need more than PCIe 4.0 x4 bandwidth for your application you should look for a board that splits the CPU lanes as then you can get two x8.
H6 Flow will absolutely not work for what you're trying to do. Pretty much every compact mid tower will not have enough room at the bottom. Many regular mid towers won't either so you'd really need to just look for installed builds in whatever case catches your eye.
Consider a PC configuration tailored for a dual 4070 Ti Super build using an Intel i7 processor. Ensure the motherboard supports dual 4070 Ti slots and has sufficient PCIe lanes. Pair it with a high-performance case that accommodates the cooling needs of the i7 and dual GPUs.
The motherboard and case rely heavily on the dimensions of the cards you choose. The MSI Slim cards can fit into any motherboard with two PCIe slots available, provided they don’t sit directly at the base. Alternatively, you could use a case such as the Lian-li O11 Dynamic EVO, placing one card in the main PCIe slot and the other upright in the secondary slot. There are numerous possibilities, so it comes down to confirming your goals and checking for compatible components.
