I would like to share test i have done
My System
Rampage V Extreme 10 (firmware from 1003 to 1701) default microcode B00000C
E5 2696 V4 oem SRJ20 (production unit)
This motherboard does not boot without a microcode for broadwell EP
I have deleted it with UBU 1.6.95 and motherboard do not finish his post rebooting with A2 code
I can boot it with old microcode
B00001C and
B00001D but not with
B000021 i have not tried to flash B00001F (pay attention,
this is a direct injection with UBU and then flash via flash back option)
So I stay with B0000C and boots as usual in Windows
I removed MCUpdate dll renaming it
and then i have tested all microcode you can find here using microcode updater
https://downloadcenter.intel.com/download/23829
So in HWinfo64 i can see all version i have installed B,C,D,F,21
Obviosly system is in power option performance mode
Tested in all that conditions all efi kindly given from

2) is there a owner of a motherboard with a single V3/V4 Xeon (not dual WS motherboard owner) who cn boot without Haswell EP/BroadwellEP Microcode?
Then, if you have any ideas.... I would like to try it!
