Hardware Virtualization GA-EX58-UD3R LGA on in BIOS but not recognized by Windows/VM

[cairo140]

Hey guys,

I'm running the GA-EX58-UD3R LGA 1366 with Core i7 920 and 64-bit Windows 7, and I have enabled the Virtualization Technology option in the BIOS, but Windows and all my applications keep on saying that it's not on. The Hardware Assistance Virtualization Detection Tool says:

Hardware-assisted virtualization is not enabled on this computer

Before you try to install Windows Virtual PC on a supported Windows® 7 edition, enable hardware-assisted virtualization in BIOS.

How do I change virtualization settings in BIOS?

When I try to start XP mode in Virtual PC, it complains:

Windows XP Mode - Windows Virtual PC

'Windows XP Mode' could not be started because hardware-assisted virtualization is disabled. Please enable hardware virtualization in the BIOS settings and try again. If hardware virtualization settings is already enabled, you may have to disable Trusted Execution Technology (TXT) setting in BIOS or update the system BIOS.

I haven't updated my BIOS since I bought the motherboard. Is there a guide on how to do it safely?

[wazza300]

on the main page read on how to safely flash using q-flash and a memory stick,dont use @bios as if it goes wrong it will brick your motherboard and it will need rma'ing....theres also a list of latest gigabyte bios on the main page too,just select one for your board and update it,beta bios's are fine to use so dont worry i run my pc 24 hours a day on beta bios with no trouble

Fair enough. How do I found out the exact version of my motherboard? I've narrowed it down to the following options:

GIGABYTE - Support&Download - Motherboard - BIOS - GA-EX58-UD3R (rev. 1.0) or GIGABYTE - Support&Download - Motherboard - BIOS - GA-EX58-UD3R (rev. 1.6)

I can't figure out whether my motherboard is rev. 1.0 or rev. 1.6.

do you have cpuid? download it from overclocking tools on main page and click motherboard it should tell you what revision on there

I couldn't find the revision number with either of the tools you provided, but they did tell me my current BIOS was version F1. I noticed that the rev. 1.0 BIOS versions were all F then a number while the rev. 1.6 BIOS versions were all F then a letter. Also, to confirm, I looked at the physical motherboard, and it said in really small hard to find text, Made in Taiwan rev. 1.0. So I downloaded F8, and I installed it through the BIOS. All is fine now. Windows recognizes the Virtualization Technology. Thanks for your help!

ok im glad you fixed it i wasnt sure if cpuid or everest lets you see the revision its worth getting everest too

Virtualization enabled in the BIOS
Disable it off in the BIOS
Save & Exit
Cold start
Enable Virtualization in the BIOS again
Save & Exit
Another cold start

It should be detected then.

You should find your mobo's revision # in the lower left (bottom rear) corner.
It will probably say REV: 1.?
