^many thanks
I've used the bios from the previous post and it worked nicely with an e7500,
before this bios, with the stock FE bios for my 3.9 board it would work OK enough, but it lacked full access to things like SSE4.1 and the multiplier was locked at 6x, also the bios would report a vcore error...
with the stock FI it was similar but worse, for some reason windows 10 would fail to boot...
with the modded FI from the above post it boots fine, no vcore errors, full instructions available and also full 11x multiplier!
a big performance gain from that.
before vs after on geekbench

(it reports 2.2GHz for both but trust me, without the microcode mod it was locked to 1.2GHz)
