ASUS WS C621E SAGE custom bios with xeon es


New Member
Hi all,
there was a discussion Wall regarding mentioned asus mobo at russian forum, to modify bios so the skylake 3647 es xeons can boot up.
I have attached the modified version, but please note it is NOT TESTED as its notoriously hard to find anyone with es + factory incompatible mobo pair . I wrote to the originl author so he will join this thread a bit later.
Dropbox - WSC621ES.cap
I am currently assembling 2 es with x11dph-i but looking forward to any chance to get it working with asus.

it's best to get a programmer and back up original firmware before doing this, if you don't wanna brick the board. I have Dph-i with two es cpus. I will get asus board if this confirmed.

Actually no

I got a pair of QS 8180M and they worked on all bioses

The QS 8180 M were less than 1/6 of the retail price
Work flawlessly - I fact I set both cinebench highest 2x Xeon scores
I bought (and returned) several ES varieties and despite the reengineering of bioses I could not get them to work
