I put Xeon L5420 771 socket CPU my GA-EP35-DS4 (rev 2.1) mainboard.
I used latest F6 BIOS.
Xeon worked, but intel Speedstep, did not work. (It was not SSE 4.1 also)
I made modified BIOS from F6.
I used this instructions and utilities.
My mainboard works well with new modified BIOS.
I have speedstep support and SSE 4.1
