P67A-UD5-B3

[awahwah]

Hi Guys,

First post but i've been readin the forums for a little while now.

Maybe one of you would be so kind to answer the following recarding the P67A-UD5-B3 bios.

Just got mine today and it shipped for F1 bios, can i update the bios with the non-B3 bios's?

Thanks

Hi and welcome to the Gigabyte Forum.

As the boards are identical as far as I know in theory there shouldn't be a problem but I would be unsure if it came to it. What I can't understand is why you would want to anyway. The B3 BIOS has to be newer than any of the previous boards as it has come out since and will have had the latest BIOS installed at time of manufacture. If you check the date of the BIOS you will find the F1 on your board is newer than the F6 on the old boards.

DM, you are correct.  F1 date via CPUZ v1.57 states  14/02/11.  Plus F1 has PLL overvolt too.  Just fyi, CPUZ will not read the cpu core volts correctly.

[Dark Mantis]

That's what I figured.

What reading do you get for your core volts then ?

1.080, so i believe an update may be required.  Work ok with my old UD4.

I am getting a reading of 0.912v but that is the rev 1.0 board

[awahwah]

I t never changes with load.  ET6 reads the correct volt along with HWMonitor, though HWMonitor will not read the +12 volt correctly.

So, I think they've change something else within the B3 stepping and the software guys need to catch up.  Pain the a** while I playing with oc'ing. 

The UD5 requires less volts then my old UD4 B2 did so far.  4.2 is prime blend 2 hrs stable for 1.24v, I needed 1.26 on the UD4 - I know 2hrs isn't long enough but I use 2 hrs as a good indication of stablilty.  I'll continue to play with it over the next couple of days and report back via this thread but this board does seem to be better

Good luck I will keep an eye out on this thread  for your progress.

Ok, little update for you,

4.6 Ghz on 1.33v LLC 1  (1.37 bios with - .020 DVID)

QPI @ 1.080
SA @ 0.935

The UD4 woudn't do 4.6GHz for me.

[Dark Mantis]

Yes that is the maximum stable overclock I could get with the voltage untouched. That is by just upping the multiplier, I haven't tried playing around with any other settings yet and still using the air cooler.

You can't use the older B2 boards BIOS with the new boards.

And until CPU-z is updated, the voltage you see in Vcore is the actual applied QPI/Vtt value by auto or what you have manually set.

I think that a lot of this confusion over the BIOS versions could be avoided by Gigabyte adding a BIOS tab on the B3 motherboard page on the website as there is simply no mention of BIOS versions on it at all. I will contact them and see if they can rectify this situation as a lot of people seem to be having a problem with this.

That would be great DM

Another update,

4.6 with the setting posted above isn't quite prime blend stable.  I think -010 dvid would sort it but I don't want to run highish volts through my cpu. Knocking the multi down to x45 - rock solid, which I' very happy with.

I must resist sticking 1.4volts though it and gun for 5GHz

Yes the magic 5.0 is so near  Go for it!
