Hi,
I have an ASUS Z10PC-D8 that I've tried to upgrade from Xeon E5-2678v3 to E5-2690v4, with limited success. Here's a list of the steps I took and what happened.
Start with running system with 2x 2678v3 installed. All 8 RAM slots populated, 64GB. Both EPS 8-pin connecters used. 800W Corsair PSU.
Update BIOS from 0303 to 3104. Reboot into OS to confirm all is well.
Remove power cable and CMOS battery.
Remove 2678v3's, insert 2690v4's. (usually would start with one, I was hoping to finish fast)
Insert new CMOS battery and apply power.
Boot failure. Standby lights only, no ERR CPU or CATTERR LEDs. No fans.
Remove CPU 2 and its RAM, mark CPU with "?"
Boot success! Normal OS boot and operation.
Remove CPU1 and insert CPU marked "?" Boot success!
Place former now known good CPU1 into CPU2 socket along with its RAM. Boot failure.
Replace both CPUs with former 2678v3's. Boot success, normal operation.
Not sure what to do next. It will only run with one, as if they were uniprocessor CPUs.
