@Lost_N_BIOS the Inspiron 3847 has wifi built in on the board has one less pcie x1 slot. The 3020 has an odd 8 pin power connector the 3847 has the traditional 24 pin. other than that the layouts look similar.

Hello Guyzzz,

I see these options in my bios via AMIBCP

1) Intel Virtualization Technology (Vanderpool) -dasabled by default but shown in BIOS settings
2) Intel TXT (LT) support -disabled by default, not shown by default in bios
3) VT-d function on MCH -disabled by default, not shown by default in bios

but only one works on my CPU i know.. and it is OK

Hi,
BTW I have found that some O'C unlocked CPUs have disabled VT-d I/O.
E.g. my i7-2600K intel ark says no

while standard version of i7-2600 have Vt-d

Did someone investigated how is it disabled on K version? Is it done in silicon by LASER burning of some jumper or is it disabled by microcode or BIOS? Any chance to enable it via MSR or old ucode?
