Please Help, Need help choosing mobo for 3600

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Every ATX mobo running X370, X470 or X570 chipsets have option to split the 2 PCIe slots (both wired to the CPU) into 2 x x8 lanes.

You could use a x1 server GPU in some lower slot, if no secondary M.2 drive is used.

	Thanks for the reply, I dont mind GPU slot having 8 lanes as its only a server and the GPU is only there to run the monitor, no gaming etc.

	You aren't going to be able to do it if you insist on 16 lanes to the GPU, there simply aren't enough PCIe lanes available as there are 20 PCIe lanes available from the CPU, and 4 more PCIe 2.0 from the X470 chipset. What you could do though is set two x16 slots to run at x8 each; for most GPU's, 8 lanes really is enough. I know the Taichi can be set up this way, haven't looked at the other boards but I'd expect similar.

	Hi all, I hope you all can help, I find the spec sheet on the website confusing when it comes to PCIE slots. I'm thinking of buying a Ryzen 5 3600, and I want a ATX ASrock mobo to go with it, My only issue is that I need slots for the following: 1 x GPU (low power) 1 x RAID card (8 lane PCIE) 1 x M.2 SSD Must be ATX I cant seem to find any that have a 8x secondary PCIe slot?
