Hello,
I will try and explain this to the best of my ability. So I bought this motherboard for the 4th M.2 slot. I had the B650E-F Gaming Wifi before that. I really wanted better compatibility with DDR5 memory, and that 4th M.2 slot, so I upgraded to the X670.
First board had bent pins on the CPU socket, so I RMA'ed it and got the 2nd one. This one booted. But right away, I noticed BSOD's and just overall instability. I always had video on my monitor, but it would BSOD and crash within a minute or so. The only way to stabilize it was to remove the top most NVME, from M.2_1 and everything stabilized. So this brought me around to researching blah blah and here I am. Let me list all the storage on my build, and my understanding of which bus they are all on. If I am wrong anywhere, please correct me respectfully but firmly (lol) so I can understand this better.
CPU bus - 24 PCI-E lanes
- 16 - to my graphics card (Populated with a RTX 4070 TI)
- 4 - to M.2_1 (Populated with a 4TB NVME)
- 4 - to M.2_2 (Populated with a 2TB NVME)
Chipset bus - 12 lanes
- 4 - to M.2_3 (Populated with a 1TB NVME)
- 4 - to M.2_4 (Populated with a 1TB NVME)
- 4 - to PCI-E Expansion Chipset (I have nothing in either of the 2 additional PCI-E slots. Empty)
But then I also have a 500GB SSD, and 2 8TB (RAID 1) platter hard drives connected to SATA. Theoretically I should be able to run all of this. I'm not going over on PCI-E lanes anywhere, and I don't have to bifurcate anywhere. My motherboard manual doesn't tell me anything otherwise either. Where am I going wrong?
On one of the BIOS revisions I tried, there was an option to Bifurcate the GPU slot with the M.2_1 slot, but doing this prevented my PC from booting again, this time getting stuck on the VGA QLED light. Only way to get video on the monitor was by using the onboard video the motherboard provided. So this seemed to completely make my GPU inoperable. So I turned that setting off.
The latest BIOS revision completely didn't work at all, as it wouldn't let me Enable CSM and boot from my OS drive. So I am currently running the only BIOS revision that completely worked for me, which is 1415. It's an older one. And it's what the Motherboard shipped with. Any advice anyone?
