We bought two of these boards a month ago and tested them, they worked great and accepted dual Xeon V4 even before bios updates.
We decided to move ahead and buy nine more boards, the shipment of course was drama but the boards survived.
Now to the real issue
None of these accepted a single Xeon V4 to begin with, only after putting a V3 in them and updating the bios to the latest version did they accept single a V4. But in no way are we able to get them to run dual Xeon V4, we tried every bios version, ram combo, psu, jumper setting and other tricks to get them to POST with a dual Xeon V4 config. Sadly nothing works, the only hint i found to the issue online was a post regarding the WS version of this board with a quote from Puget Systems
"The Z10PE-D8 WS works fine with the v4 processors... as long as it was manufactured after October of 2015. Regardless of the BIOS version installed, if the board is older than that it will not work with the new processors. We've run into this once, but Asus had warned us about it. I have been told that the only solution is to send the board back to them (Asus) to be updated."
Z10ped8 ws works fine with e5 2699 v3 chips (2) However With approved bios 3204, ram, power supply etc (the same as above) When I put 2 Intel e5-2699 v4 chips in at the same time, the board won't even boot, dead nothing. Spare identical board, different e5-2699 v4 chips, rinse repeat: other...

These boards we got in the 2nd shipment of 9 boards are clearly of a different batch, the revision of both boards in batch 1 and 2 is 1.02 sadly i cannot find the date of production as described in that post.
So buyers beware: If you want to run dual Xeon V4 on these, make sure you get the newer version from the seller.
Update: Got an RMA from ASUS for this known issue, costs me 9 euro's a board to fix so i send them to them. Really hope they will return working.
