ive reflashed now several times, tried different bios versions too, tried it on chip#1 and #2. doesnt work. i guess its somewhat related to the pcie lanes, maybe my cpu is damaged or the board itself. the cpu was running 4.5ghz/4.3ghz uncore both at 1.185v 24/7 tho. i did run a 8h realbench stresstest overnight without any problems, i dont think its the cpu. might just rma it all together and move to another board if i cant fix it.

ive removed the monoblock, reseated the cpu, flashed back to the last 100% working bios (1902) and tried the gpu in different pci slots. the gpu works no matter what slot im using. however the soundblaster zxr and the samsung 950 pro still does not get detected neither in bios nor in windows obviously, both devices get reasonable warm tho, so theres current flowing. besides that everything works perfectly fine. anyone got an idea? :confused:

i dont think that the ssd and the soundcard both just died.

/edit
just ordered a 6700k and a VIII formula. dont have anything right now to test the soundcard or the 950 pro. kinda weird since everything else works absolutely fine.

If neither PCI device works there indeed may be a MB issue. I feel sorry for you if you have to RMA it cause I have spent the last 3 months waiting for stock to replace my own and they haven't had any stock with none coming in in the forseeable future. 😞

i installed the pce ae68 wlan card today and the r5e does detect it and it works fine. the soundcard and m2 drive still dont work on the r5e.
however i have received the M8Formula today, and the soundcard still doesnt work on it, however the m.2 950 pro still works fine. i dont really know the problem, i dont want to blame the board but in the past some voltages just set themself higher (scary higher) than stock in the bios, maybe that happened again and it killed the card. mabye the card just died and the m.2 was mourning haha. i dont know. but its working for now. i dont really need the extra cores right now so i just stick with skylake and rma the board, then sell it with my 4.5ghz @ 1.185v 5820k and the monoblock all together, x99 was the worst chipset for me, microstuttering, bootproblems with some usb devices, it just got annoying to unplug start/reboot. but well... on to the z170 adventure :cool:

Are you occupying PCIe 4_8 ? See page 1-19 of the manual on shared bandwith on that slot will disable the M2. if it's occupied it will wont work.
