Hi guys

I have finally built my main rig (after 2 months waiting for the 7970 lightning blocks).

However, I cannot for the life of me get this motherboard to boot with Ivy Bridge. The fans all spin up and just as the screen should turn on the system reboots.

When I put in my older 2500k however, the system boots fine like there is no problem. PLEASE NOTE ONLY THE CPU CHANGES TO MAKE IT WORK.

I am on the latest BIOS for the Gigabyte board (U1H) and have cleared the CMOS several times in the hope it will boot.

The weird thing is - when I first got Ivy Bridge CPU I installed in my Prodigy rig on an ASrock Z77E-ITX I had what I think is the same issue of the board seemingly not booting. RMAed the ASrock board back to Overclockers who said it was fine and sent back to me.

So, what are the symptoms of a faulty CPU? I am SCREWED if it is as its just been sat here not installed for over 2 months as I was waiting for the 7970 block to arrive at OcUK! £180 down the drain?

Any help at this stage would be GREATLY appreciated - causing lots of stress tbh.

Cheers

Tom

Try F12 bios

but,

It seems like you have identified the fault by trial and error. I would raise an RMA for the CPU as your next step.

Sorry guys can you clarify for me - I updated from F10 or something IIRC. Are you saying I need to roll back to F12?

I'd heard that once you go UEFI there's no rolling back...

Many thanks for the quick replies.

Seems to me though if the SB works in that bios, the IB should as well. So it is still suspect.
 
Well, I'm unsure how exactly I am meant to even rollback to F12 now that the new U1H BIOS is on there...

I had to make a DOS bootable flash disk to install the UEFI BIOS (cannot do it through Q-Flash).

Arg!

Ignore. My post was based on wrong information. :o

I'm fairly sure Gigabyte starting releasing the beta UEFI bios updates as all the P67 and Z68 boards of theirs couldn't overclock any Ivybridge CPU on the old style BIOS as the multipliers were locked. If you remain on any of the older BIOS the CPU cannot be overclocked at all, although the CPUs are supported. I have no idea though why the UEFI BIOS wouldn't allow booting of an Ivybridge processor when it was these processors that brought along the UEFI updates... :confused:

No, U1H is only a Bios Utilitty update.

Stick your 2500k back in and check, go to the Bios and you will see what version you have, F10.
If you have looked at the link, all Bios Updates start with the letter "F".

Sorry but that's completely incorrect, U1H is the latest bios, F12 is older, the reason its called U1H and not F13 is because the type of bios being used changed so they changed the naming convention.

Exactly... The 'U' type BIOS may not be listed on the websites officially, but they're the latest type BIOS as far as I'm aware. I thought Gigabyte were trying to upgrade their older line of motherboards because of the problems they've had with Ivy.
 
My apologies to the OP and other fellow members. The info i offered was misinformed, as the more correctly informed members have rightly pointed out. Just spent the last few hours doing a little research. The U1H is the latest Bios, albeit a Beta version, as the full official UEFI Bios has`nt been released yet.

Mega :o:o
 
Hey no problem bro - at least I'm not going mad!

But still got no frickin idea how to solve this issue - it really is a case of i5 2500k BOOTS 100% perfect into windows 7 very fast, 3570k NO BOOT constant restarting when posting...

I've NEVER had a faulty CPU - are these the sort of symptoms one would expect with one?

I'll be annoyed if it is faulty tbh as OcUK are highly unlikely to replace it several months down the line... :S

Why shouldn't they if it's faulty and within warranty?

If it is a retail CPU you have three years or if OEM you have 12 months, send it back for a test, OCUK should then replace it if faulty.
