Got this board today and having a wierd issue...

I think it's a faulty board, but just wanted to check I'm not doing something silly.

Board boots from fresh CMOS clear without issue.
I can clock it nicely with vcore on Auto and LLC on auto... Works ok at x50 and in windows reports at 1.35v vcore, but the chip does more in my other board (Asus) it just needs more vcore.

When I go into the UD4's bios and alter the vcore voltage in any way I get a complete failure. Once the vcore is set and I do F10 to save and restart the machine comes back, but the voltage is not set. If I do F10 save again the board will try to fire, the phase LED's all light, no sound from the speaker and no video, it will then just keep shutting off and re-trying indefinatly. I have to power off the PSU and short the Cmos jumper to get it back.

I have tried booting from a clean CMOS and setting the vcore to + 0.05v and the same happens.

I have tried Bios F3 (Default) and F7b and F7f all are the same.

Does anyone with a Gigabyte P67 board have any ideas... am i missing something simple here?
 
I'm on the UD3 board and have similar issues.

If I start messing with vcore the PC powers up/down until I reset CMOS.

I can't get a stable 44x overclock on this board, the LLC just doesnt seem to work!!

Can't make my mind up what to do, refund and get MSI or wait for a good BIOS.?
 
Give me a moment and I will post up the settings for that board.

They are a little different from the UD7.

But in the mean time you do need to go into CPU options and enable the PLL override function.

LLC 1 or 2 if you are going extreme.

And before I forget set your limit in turbo watts to 300 and the amps to 300 too. It is just something that works for extreme overclocking and that board.

And what are you Intel power management settings? Disable them all.

Thanks 1Day, but I fear its a bit more than the extreme overclock settings because I can't alter vcore even at stock CPU / ram speed.

To explain the symptoms further...
Reset CMOS and boot
Boots at default with boot speed 3400MHz and turbo set to 3500MHz
Go to voltage settings and set vcore to say 1.2v
F10 and save... system reboots
Vcore is unaltered and also boot still at 3400 but turbo now at 1600????
Then re-boot and we get the indefinite power cycle.

Even setting the vcore back to AUTO after the first boot does not prevent the power cycle. It seems altering the voltage does something terminal to Turbo.

I've not heard of any issues with the UD4 only the lower end UD3 (no suffix)

I assume you by above mean VOLTAGE not RAM settings, can't think why you would set your ram to 1.2v

What about if you go to voltage and set your CPU Vcore to 1.35V do you have problems then?

Yea defo CPU Vcore (my bad typing i meant Voltages not RAM)... setting it to anything manually causes the issue. tried 1.35, 1.22 all sorts.

I cant find any similar comments on Google so I think i must just have a bad board :( I have requested an RMA
 
Funnily enough, the symptoms you mention in the OP are exactly the boot issues I had with the Asus - mine was not a lit ram LED or lit GPU led, all phase lights on but no beep, no video just powered up fans etc and nothing else. And I had similar problems with vcore changes until I upgraded the bios from 0402.

Since then thats always been how my P8P67 boot issue has manifested itself, although the vcore adjustment issue dissappeared.
 
WOW that was really quick turn around service - pretty impressive if you ask me.

Well I have paid for the second board and will get a refund on the old one when they process so sometime next week.

Straight in at 5GHz and running Prime95 to burn the processor in :)
 
Simon,
Which 'board do you prefer, the P8P67 Pro or the UD4?
Which allowed the highest stable 'clocks with the lowest vcore or were they both the same. Your thoughts would be much appreciated.
Cheers
 
I much prefer the P8P67 Pro.

Clocks were just as good on either board. The Asus just feels more solid and with more features. I love the Asus Bios, where as I hated the UD4 Bios.

Only negatives with the Asus IMO are that the RAM slots don't have clips on both sides meaning you have to be careful that they are properly inserted and the CPU socket seems a bit less reliable, meaning reseating some CPU's is required to get good contact.

Oh and another big point for me is the Asus windows software. this is excellent and lets you alter things including the CPU Multi in real time... The UD4's software was poor and only let you adjust the CPU multi down - the Asus goes up and down as required.
 
I'll stick with what i have then :)
Just fancied a play, but may wait for the revised Maximus with the new chipset when it comes.
Cheers
