Based on the image they've got the hyper drive in the bottom slot and it's not working, assuming the drive isn't broken, it just reads to me like it needs to go up a slot.
For the time it takes to remove the hyper card and plug it back in again it's not going to hurt just to check either way.... besides it wouldn't be the first time a manual is wrong lol
It's also something they were advised wouldn't work by the (I'm assuming) company that built it... relinking below in case you missed it
Installing my 10th hard drive - bandwidth compromise
Hi, I wanted to get 2nd opinion from the OC community. I have a Z690 system with a 12900k CPU, 3090 GPU, Maximus Z690 (Hero) 64GB of DDR5 RAM and 9 drives. I have six Samsung SSD 870 QVO 8TB (4 of them in Raid 0), one NVMe Samsung SSD 980 PRO 250GB, one NVMe Samsung SSD 980 PRO 2TB and...forums.overclockers.co.uk
Yeah, it wouldn't hurt to try and I wouldn't be surprised if the manual was wrong (or missing things). I did read the link, but it's not entirely clear (what they're referring to).
From what I gather, G5_1/G5_2 would shift the Hyper M.2 demand for lanes to the CPU (halving the graphics lanes, even though for some reason it can only use 4 of the 8, maybe because GPU lanes lack bifurcation)?
The Hyper M.2 slots (1&2) currently work fine, but the bottom board M.2 slots don't and I can't see any reason why (I can't find any exclusions in the specs/manual), but G4 does use chipset lanes (which the bottom M.2 slots also do).
From the chipset diagram, Z690 has 12 PCI-E 4.0 lanes and 16 PCI-E 3.0 lanes available (assuming some aren't in use for other things).
From the chipset, the Z690 Hero has 1x PCI-E 3.0 M.2 and 1x PCI-E 4.0 M.2.
The third full-length slot uses 4 lanes of PCI-E 4.0 from the chipset, but the manual suggests it can take another 4 (which it must do, because otherwise the Hyper M.2 card would only have one functional M.2 slot?).
This arrangement for a high-end board is a bit weird, because the MSI Z690-A has 2 PCI-E 4.0 M.2 from the chipset and the Asus Z690-A has 3
So, I can only imagine that Asus chose this arrangement for the Hero on purpose to support 5 M.2 slots with the Hyper M.2 card.
