Can anyone confirm if Intel Xeon QDCS only works with DDR3?
sure it works with DDR4. but without the microcode and Intel RefCode support it will not work.
edit: have seen HWinfo recognize a QEY8 as a QDCS (145W) by mistake....

seen it working on a ASUS Z10PA and the earliest BIOS available.
edit: shown as QDCS 145W, so maybe not a true QDCS.

So now I should try my luck by adding microcode to the BIOS right :))
i took a look at the X99-8M-F, and was shocked.
i have a X99-8M which has 6 phase VRM and a real C612 chipset
the X99-8M-F shippes with only 3 phase VRM and a B85 chipset. take care of your VRM they are not made for 135 watts.

Thanks for the warning, I am aware of that already but I just wanna try if it works (additional VRM cooling is a must tho). I'm also thinking of getting myself an used X99-AD3 to pair with this power-hungry monster.

I have tried adding 306F0 microcode to the BIOS, but the system still refused to boot. Fan spinning but no beep at all. The CPU did heat up. Any suggestions?

If that's the case then the 306F1 microcode already exists in my BIOS. What could possibly be causing the problem here then?
even if the MC is missing or memory is not supported there must be an error post code.
if the CPU does nothing it is dead or the BIOS lacks support of this ES stage.
