Spread can't be set to middle or up. When i chose middle or up - i had cycle reboot (not bootable)

DeathBringer from overclockers.ru say that is true

But this is solved with stock BIOS and non-broken ME, nothing more to try and fix since it was fixed originally until it was broken with ME Cleaner.

That may be correct, I have not tried it myself, never had a problem like you mention because I never use ME Cleaner, if I need to disable ME I can do myself manually
Which is rarely needed, only certain Xeon situations I've seen needed it, and not ME cleaner way either only manual.
