Gigabyte Z68XP-UD4 UEFI problem

[Jacky444]

Hello,

I've overclocked my I5-2500K on Z68XP-UD4 with F6 bios easy to 4.2GHz, 4.5GHz was kind of unstable and anything further.

But since I've upgraded to latest UEFI U1g bios I can easly hit 4.5GHz stable (tested prime 24h test) but now I've ran into a whole new problem.
I can't shutdown, sleep, hibernate computer because I'll run into BOOT LOOP like on older F4 bios. Now in F6 I can disable PLL Over-voltage and it doesn't happen, but on UEFI there is no such option ?

How can gigabyte release new UEFI bios without such important feature or am I missing something ?

Please help/Share throughts.

P.S.: I really like UEFI cause it boots up much faster and UI is much more friendly.

Hi

Firstly I would just like to point out that although this is Gigabyte's official forum there are not many staff members who actually frequent the forum. We just help each other mainly but of course if you want to contact Gigababyte officially then there is always GGTS. You can write to them here :

Please expect several days for a reply.

Thank you for information =).

I was hoping, actually, that anyone would respond to help me look into the problem but okay .

Funnily enough, I've just posted a similar issue to this on my GA-Z68A-DH3-B3. I'll follow both threads in case there is an answer. Seems we may have to wait for a new bios though - does anybody know if that is likely?

Extremely sad is after 6 months gigabyte still haven't updated BIOS to fix boot loop issues... Really sad!

I'm a little disappointed

Hi, I'm using a 2600K & the GA-Z68XP-UD3P under the UEFI version U1G, and I can disable CPU PLL Overvoltage under Advance CPU Core Features.
Also, try loading Optimized Defaults and then re-enter your OC settings, drive options, etc. and see if that helps with boot loops.
Honestly, there's still no clear answer to why boot loops happen, but it just seems to be a different issue for everyone.

the uefi bios states its BETA biso, so its not final.
