Does the B450 AORUS PRO support running the RX580 Crossfire?
Does the B450 AORUS PRO support running the RX580 Crossfire?
He had his PC seized at CEX, and they removed the RAM, CPU, and storage, then either discarded them or returned them to the customer. Some people said he shouldn’t be forced to keep the motherboard, suggesting he just take whatever he wants with the case. He kept the case and PSU but got the motherboard, which was handy since I was in the store at the time. I picked it up back there and placed it on my tech Jesus mat to test it out before deciding. I’m wondering if it can run two RX580 graphics cards together. I’ve seen others use different setups—especially with larger X4 slots—and performance can differ a lot. Should I wait until Wednesday to get the A320M chipset, or go for the 2 metal slot boards instead? I might donate this board to someone who could really use an upgrade.
The instructions on the product website confirm it. However, it's unclear why you'd need to do that.
This board features three PCIe x16 ports, though only one is physically PCIe x1 and another is PCIe x4 (provided by the chipset): https://www.gigabyte.com/Motherboard/B45...v-10/sp#sp 1 x PCI Express x16 slot, operating at x16 (PCIEX16) * Actual support may differ depending on CPU. * For best results, if just one graphics card is planned, install it in the PCIEX16 position. (This slot follows the PCI Express 3.0 standard.) One PCIe x16 slot, running at x4 (PCIEX4) * This slot shares bandwidth with the PCIEX1_1 and PCIEX1_2 slots. The PCIEX4 slot functions in up to x2 mode when the other two slots are active. It operates at up to x4 mode if both PCIEX1_1 and PCIEX1_2 are free. One PCIe x16 slot, running at x1 (PCIEX1_2) 1 PCIe x1 slot (PCIEX1_1) (Both slots follow the PCI Express 2.0 standard. SLI demands a minimum of eight lanes, so you need two x8 or better slots. Unlike SLI, Crossfire is flexible, allowing the second card in the PCIe x4 slot as long as you don’t use the other x16 slot. The performance with Crossfire won’t match having two x8 slots, but it will be better than a single card in games that support it. Not every title supports Crossfire, and even fewer will in the future, so I wouldn’t suggest adding another RX 580 just to boost FPS.**
