NVLINK Disabled After Upgrading Motherboard
I just upgrade my system from an AMD x570 chipset to an intel z790 chipset for a better CPU for modeling aspects and DDR5 ram. I've used dual 3090 Ti cards for GPU rendering with an NVLINK bridge to pool Vram. After upgrading to the new motherboard, there is no longer an option to enable nvlink in the nvidia drivers. Upon further research, nvidia has dropped all support for SLI on the z790 chipsets therefore disabling NVLINK as well. Even though the hardware should have no trouble supporting it. There are plenty of PCIe lanes and I made sure they would run in 8x / 8x mode. This is a HUGE disappointment as the whole reason I bought 2x 3090 ti's instead of a 4090 was to use NVLINK for memory pooling.
This is incredibly frustrating to be going BACKWARDS after an upgrade, and I may have to consider downgrading to my last gen board and CPU. I've looked and looked and I can't find anyone that has a workaround for this. This seems like a total cash grab from NVIDIA trying to get us to use there pro RTX 6000 cards for over $5,000 a pop as that's the only way now to get a larger Vram pool.
