Dropouts when bitstreaming Atmos through an HDMI 2.1 AVR with nVidia 3xxx GPUs

That's ALL it displays. So it's not even trying to post. My guess is the mobo is dead. At this point I'll see what happens in July with the AM5 Zen 5 CPU's and motherboards. I'll just build a new machine and use the 3080 machine until I can make that happen. I tried re-seating the CPU and that made no difference so it really does seem like the mobo has died. Which is frustrating given that it was not a cheap mobo when I got it a few years ago.

Sorry to hear that. Did you try using another slot for the GPU? As long as the power cord was disconnected when you first swapped the 3080 and the new 4080 (as powering off isn’t enough to cut off all power to the mono), the most likely thing that could have been damaged is the GPU slot due to excessive pressure when you took out the old / put in the new GPU. Worth trying another GPU slot on the mono with either GPU, probably the 3080 first in case your 4080 is DOA.

As I mentioned before, I can't use another slot. There's literally no room. When I say this thing takes 3 slots, I'm not joking. The only other slot is at the bottom of the case and has literally no room. So that's not an option. One thing I can do and I may consider it when I have a few hours is rip out the mobo from the ASUS machine and drop it in another case. I have an old intel machine kicking around (9900k) that has a water block that should work with the intel board from the ASUS. Then I should have enough room to mount the 4080 on that board. But for now I'll probably just install MC32 on the ASUS machine until I can rebuild my main machine. Then I can have the ASUS machine for a bedroom HTPC.

Well, I have bad news. It took four films but I got my first Atmos freeze :( so it looks like the 4080 might improve things but doesn’t fully resolve the issue. I need to investigate what’s happening before deciding if I send the 4080 back or keep it.

Well, that's still better than what we've dealt with prior on the 3xxx cards IMO.

Yeah but not sure it’s worth a grand if it doesn’t fully solve the issue. I’m going to put the 3090 back and see if I can identify what’s causing these issues.
