Title: Can't make changes in MB Intelligent Tweaker in UEFI BIOS
Post by: highstream on December 13, 2012, 06:41:35 am

GA-Z68X-UD3H-B3 (1.3), Win 8/7 x64.  Flashed UEFI last night from F12 and was surprised to discover that quite a few key items were highlighted under M.I.T as if they could be changed, but didn't respond to either Enter or a mouse click. These are items, such as memory multiplier and CPU Clock Ratio, that were readily adjustable before.  Here's a list of the highlighted ones that did not respond:

Advanced Frequency Settings:
   - CPU/PCIe Base Clock
   - Processor Graphics Clock
   - CPU Clock Ratio
   - System Memory Multiplier

Advanced Memory Settings
   - System Memory Multiplier

Advanced Voltage Settings
   - all 12 items

What might be blocking all these options in UEFI?  With F12, I settled on the defaults, except changing the memory multiplier from 1.60 to 1.88.  Btw, an updated manual for working with UEFI would be helpful. Thanks,

Hi there,

welcome to the world of UEFI BIOS. I was caught out by this the first time I played with the new BIOS and discovered that you need to you the "Page up" & "Page Down" keys to adjust these settings once you have highlighted them.

As for a UEFI manual when I upgraded my Z68X-UD3P-B3 Mobo I downloaded the user manual for a Z77 Mobo and used that to get a grip on how things worked.

Thanks!  Who would have known about Page Up/Down?  Got the Z77 manual and will look through it.  Now, you wouldn't happen to have any ideas about the Marvell/Apache question I posed, would you?

Sorry, I don't know the answer to that one. I tend to run Microsoft Security Essentials, rather than a 3rd party security program so I have never come across this.

For those wondering what we are talking about check here: http://forum.giga-byte.co.uk/index.php/topic,11205.0.html

Is Marvell Storage Utility a security program?  I don't think so.  It's one of the drivers showing for the Z68 board, while Apache is an HTTP Server Project that the driver installs.  Guess you know even less than me.

I was referring to the Secunia PSI program which gave you the warning and is probably why I haven't come across this particular issue before.
