@Lost_N_BIOS Thanks, just the updated, not likely to run anything other than the 3770 with it, the Marvell for the additional SATA.
Existing install is on the Asus P8H61MX-USB3, Windows on SATA SSD, HDD for storage… I know it’s not much of an update really, but I wanted the 6 port rear audio as I was having no luck with finding port retasking. Also the native SATA 3 is going to beat the Asmedia card I was using… my old AMD X4 got more out of it with native SATA 3.
Plus, the ability to bump the 3770 to maybe 4.3 even though it’s a non-K is a bonus - might stop at 4.1, as I have some recollection that it’s as far as it can push on stock volts - maybe give it a whisker of volts and see if it will push all the way (BIG 120mm fan air cooler).
That move from H61 to Z68 should be fine, reboot for driver reinstall will be needed of course, and then activation phone in if you are not using something to avoid that.
Here is F8 with all microcodes updated - actually, I paused here, your CPUID is 306A4, BIOS F8 already has latest version possible for this CPUID - Rev 7 (9/8/2011)
I’m not sure you can OC Ivy on either BIOS type to the multi you mention. I always used Ivy on Z77 only, even when I had both Ivy/SB and P67/Z68/Z77 at same times, these chipsets simply weren’t ready for Ivy release, that’s why Z77 came out so quickly after Ivy launch.
@Lost_N_BIOS 306A9 - And I wonder if that’s why multicore enhance doesn’t show up on the other board - it doesn’t do it for Ivy, oh well, at least SATA 3 and full audio won’t mind which gen it is, oh well, it will be an adventure
@Matth79 - MCE can be hidden BIOS option. If it’s in the BIOS you are using, then it can be made visible always if you wanted.
F8 BIOS does not have this option, but the UEFI one might (I didn’t check right now)
What do you mean about 306A9? I thought i7-3700 is 306A4 - http://www.cpu-world.com/CPUs/Core_i7/In…%20i7-3770.html
Hmm, now I see both on that page!? What gives, is there two steppings for this CPU and they don’t have that mentioned, or they have some misprint error?
Anyway, here is F8 with all microcodes updated, now it doesn’t matter 
In the manual, it shows options to set the multipliers for 1,2,3,4 cores, so I guess “set 'em all to the 1 core level” = MCE, it’ll be a journey, maybe it does, maybe it doesn’t, and maybe it lets me do the up to 4 steps higher, or maybe not.
If not, in the words of the song, “2 out of 3 ain’t bad” - I still get better SATA 3 and full audio
That is in your BIOS, about the cores (1, 2, 3, 4 etc), I remember seeing that when I looked yesterday
Hello, I’ve come across an old GA-P67A-UD3P-B3 and I wanted to flash UEFI on it. Could anyone look into it and fix a bios for me? I already tried files in #5 but it returns “BIOS ID mismatch” error when I’m trying to flash it from DOS, so it is probably a wrong revision (I have rev. 1.1)? The reason for uefi is that i have an i7 3770K CPU and it behaves like a locked (non-K) one with current bios, UEFI should fix it.
This is a bios I currently use:
http://download.gigabyte.eu/FileList/BIO…-ud3p-b3_f9.exe
And I’d like to use this UEFI if possible (but any uefi would be nice for my mobo if I get it working):
http://download.gigabyte.eu/FileList/BIO…-ud3-b3_u1d.exe
If I buy a programmer with a clip (so that I don’t have to solder anything) and just flash P67A-UD3-B3 UEFI without any modifications, will it work? Are the BIOS ID modifications necessary or it doesn’t matter when I use the programmer and not an app?
Edit: long story short… It did boot with some of them (I’ve tried 3-4), but USB + some PCIe slots didn’t work so there is more to it than just bad 4 Pin Fans or audio.

Hi Lost_N_BIOS, Could you please re-post the GA-P67A-UD3P-B3 to GA-P67X-UD3R-B3 mod BIOS originally at http://s000.tinyupload.com/index.php?file_id=84239158085891922913 Cheers, Andrew

May be somebody else have UEFI mod GA-P67A-UD3P-B3?
I have the scheme MB but I haven’t relevant skills for modify flash 
@Paralen963 @Lost_N_BIOS ?
First, flash the Award BIOS from the P67X-UD3R-B3 model with the changed ID
http://mjd79.ct8.pl/p67.zip
It is best to flash the same BIOS, but the original one from Gigabyte’s website again, as there may be different IDs in different places in the ROM.
Then flash the UEFI from the P67X motherboard.
For other users - the modification is very simple. All you need is a hex editor (such as HxD). You download the BIOS Award for your board and the one you want to modify. At the very bottom you will find the ID of the motherboard (it should start with 7A) Modify the ID in the BIOS what you want to flash so that it is the same. Save, then you can already flash that BIOS. Once you’ve done that, all you need to do is upload the UEFI BIOS of the board you flashed the BIOS from.

Is it possible to flash bios from Gigabyte GA-P67A-UD3-B3 (which has support for Ivy Bridge) to Gigabyte GA-P67A-UD3 to run i5 3470 on it?
Hi, any chance to mod or upgrade BIOS on Gigabyte GA-P67A-D3-B3 rev. 1.0 to support i7 3770K O’C? I currenly have the latest official BIOS F7 (non-UEFI) and just got 3770K but disappointed that max. multi that can be set in SETUP is 39x and even wit this it boot with 37x only
Gigabyte has some UEFI version but only for HW rev. 2.0 - not sure if it would work. I also found somewhere some (probably unofficial) file P67AD3B3.U1D but it’s not clear for what HW rev. it is…
Well, upgrading ME module from 7.x to 8.x was enough, now I can set mul. up to 59x…
Yes.
First, flash this BIOS with changed ID, by me, for your board (7A89UG09)
Then re-flash the original BIOS from the board with the B3 note.
P.S. you need to upload the original a second time, because elsewhere after uploading you may still see the board ID P67-UD3 (without B3)
Thanks mate! But Qflash doesnt like checksum of your file (06F6). I fixed it by reinserting Logo.bmp with cbrom155. Now checksum is D800, but Qflash still dont like the file. What can I do?
Thank you very much! Looks like almost everything is ok, now I have Ivy Bridge Xeon onboard.
But as I saw at first loading, second (backup) bios was overwritten by new one so this dual-bios protection is not very solid 
Have issue with usb keyboard - doesnt work until windows load. Tried to toggle USB Legacy and Fast Boot on and off, but no success.
And it froze couple of times on windows desktop loading - keep looking on it.
You can try UEFI BIOS for P67A-UD3-B3. The AWARD → AMI update tool overwrites both BIOSes, to prevent this, flash it via the flashrom tool.
Command: flashrom -p internal -c “name of your BIOS chip, like MX25L3206E” -w (BIOS file)
