Gigabyte GA-MA790X-UD4 Thread

Shadowdust said:
Yeah, I really don't know why they haven't either. Other than the fact that VDIMM still freezes at 2.2 volts and ACC still isn't recognized in AOD, this is a pretty solid BIOS update. Let's hope that they make this a public release in June. :)

Oh one more thing I noticed in performance. I'm now able to up my CPU Northbridge speed to 2.1 GHz. This has significantly improved overall performance. With the old BIOS I was lucky to even be stable at stock speeds. If Gigabyte can fix the 2.2 VDIMM issue, I think this board will really be able to go the distance in regards to overclocking.

Yeah and test Ctrl-F1 it has a new option on ACC (EC Firmware) Hybrid or normal...
And i recommend hybrid to unlock the phenom II X3 710/720 (0904) correctly
 
Thanks a million for sending me this awesome bios Shadowdust! I've been priming now for over an hour with all four cores unlocked! Even niftier is that my computer actually manages cold booting now! I have no idea what the hybrid setting does to ACC, but it seems to work great.
Too bad I don't get any temperature readings on individual cores, at least not with Everest. It reports my CPU as a "QuadCore AMD Phenom II X4 Black Edition 20, 2819 MHz (14 x 201)" btw. Also, has anyone noticed a bumped up default Vcore? Mine is around 1.39, with automatic bios settings. Oh, and sleep finally works for me, even with a clocked CPU!

The hybrid ACC setting on a Gigabyte board was also recently used by Xbitlabs to unlock a Phenom II X2 550 to four cores. This is neat stuff, more info after the link http://xbitlabs.com/articles/cpu/display/phenom-athlon-ii-x2_15.html#sect0

Going Sata AHCI under XP without reinstall

I wan't this bios now :).

Now, a little tweak for those who installed XP with SATA port set to native IDE.

If you wan't to switch to AHCI without resintalling XP, here's the easiest method.
http://en.wikipedia.org/wiki/Advanced_Host_Controller_Interface

Connect your hard-drive to the Sata Port 4 or 5.
In the Bios, in the Integrated Peripheral section, there's two lines for SATA settings.
Onchip SATA Type: this is for port 0 to 3, set it to 'AHCI'
Onchip SATA Port 4/5 Type: This is for port 4 and 5. set it to 'Native IDE'

Boot to XP: windows will detect a new hardware and ask for a driver (use the motherboard CD or go to http://game.amd.com/us-en/drivers_catalyst.aspx for latest drivers)
Reboot
Now that Xp has the AHCI driver installed, you can turn off the computer and put the SATA cable back to port 0, and benefit from SATA2 improvement like NCQ under XP.

Now I'm getting loads of requests for this BIOS as well. I really don't give a damn about who is "legally allowed" to distribute this BIOS, it's free for goodness sake, so here's this beta BIOS for the GA-MA790X-UD4 (1.0).

UPDATED LINK, UNLIMITED DOWNLOADS

http://moogcoon.no-ip.org/~jickel/MA79XUD4.f3i

See if you can figure out what the other pictures in that folder are of ;)

Hi Guys,

I have been following this thread, and i do own GA-MA790X-UD4 as well. I just got my Phenom II X2 550 in today, and plugged it in. F2A Bios was successful with unlocking both the cores, however it wasn't so successful when i put a load on it with IBT. So then i have seen the Bios that Jikel posted, and loaded it up, [BTW, thank you very much Jikel:)]. I put it on Hybrid mode, and set the ACC to Auto. After these changes, it restarted but it cannot boot into OS. I have Windows 2008 Server installed, and it gets stuck just before it gets into the OS. I then booted up into Safe mode successfully, and able to ran 10 iterations of IBT without a glitch with all four cores active.

The problem is, i cannot boot into the OS itself. I restored my backup 3-4 times, set the BIOS from scratch 4-5 times. It always get stuck on the bar. Anyone had an issue like this? This happens when i disable ACC and turn the EC Firmware mode back to Normal. So it happens either way. However when i flash it back to the F2A, it boots up fine to the OS.

I am aware that it is BETA, but i just wanted to see if anyone seen something like this?

Thanks
 
I havent had such issues. I am unable to unlock the the 2 cores of my cpu with any bios. I wish I could buy a 550 but im one of the laid off unemployed. Im so bored at home so I play with this thing. :banghead: I would also like to add some input into overclocking with this board that I learned with my setup.

1. Ganged mode is best with memory in slots 1 & 2
2. CoolnQueit works and does not interfere with overlock. It saves you about 50 watts. I measured with my Kill-A-Watt meter.
3. If you set PCIE Bus speed above 114 in bios it will force PCIE 1.0 bus speed. You must stay under 114 with ATI cards to have 2.0 bus speed. This was not case with my older Nvidia 8800gt.
5. I have drastically lowed Mosfet and Northbridge temps by removing the two blue heatsinks and adding two 50mm fans to the mosfets heatsink. http://www.newegg.com/Product/Product.aspx?Item=N82E16835119052 They fit perfect, fan is thin and screws fit inbetween heatsink fins.
6. If you use onboard sound you may be able to get better sound quality using modded Creative X-Fi Drivers for Realtec found here http://forums.techpowerup.com/showthread.php?t=87523
7. Im getting best stable overclocks using ACC settings - Hybrid PerCore +4 - +6 Range
:rockout:

HellSy I just rememberd something. It may be a problem with your videocard drivers and the new bios. I come to beileive it is something to do with the PCIE Bus. If you can boot into windows with new bios in safe mode by pressing F8 before windows loads, thats the problem try setting your pcie above 115 and it will force pcie 1.0 bus speed.
 
Hmm.. I have HD 4670.. I will give it a shot.. I have formated the system now just to see if it is working .. So i will restore my backup and see if that will work.. Thanks for the suggestion.. i will keep it updated here:)

EDIT: Before i formated, i also tried something similar.. I booted to Safe mode and turned off all the services and programs.. I assume it will ignore the drivers, so i guess it rules it out ?

Yes! You have found the problem. I had the same problem. I did a bios update and was unable to boot into Win7x64 only safe mode. This is a bug that only happens when if feels like giving you trouble :banghead:. To solve load up f3i bios and do a new install while new bios is loaded. This problem only came about since I recently got a 4850.
 
Man i just formated this system 2 weeks ago and it was working all nice.. now i have to go thru all this again.. but its fine :) Its worth it for that extra 2 cores.. lol :)

So there is a known issue at the moment guys.. I am hoping that they will fix this issue with the actual release.. i guess i will wait for that.. Is there any info about the full version of this bios?
 
Interesting... At least it is a known serious issue. I hope they will get that fixed by the actual release...
 
Their was another site I was able to access that I can no longer that list the real Technical Service bulletin for GB but I can no longer access it. It request a login. They may not realease another bios for this board in awhile. I can see that they have more important urgent isses that need fixed for boards that are on the market. I wish they made all the the UD4 Boards like the UD4P. Almost about the same. It seem to me like they only ran this motherboard on their production line once then cancled in return leaving only a few thousand out their while the impoved UD4P went into full production.
 
I can't launch IBT anymore, but i tried loading the system with OCCT. As soon i hit ON button, OCCT reads 1.42v. Since i cannot see the actual temperatures, this does not make me comfortable about it.. Is this normal? I havent seen this kind of a behavior with my previous chips.

If i knew they werent going to keep UD4 up, i would have not bought it.. The only difference i see is the 2 more SATA ports.. whats the difference? the wiring? power?

I'm on f3i and i think that i have the underlined bug.
When i plug my HSDPA usb modem into certain usb ports it crashes.


Also vcore stucks @0.8v sometimes and vmem @2,2v

:banghead:

Better power, 8+2 CPU VRM power phase to cpu. Ferrite core choke. I use HWmonitor to monitor my temps. We get excellent temps on these boards. I have another 780g GB with mosfets temps of 100c+ without a heatsink on them. Been running about a year like that. Im at 1.63V on my cpu with this board and I never go over 52c with my fan mod. 65c without fan. I just like my temps under 60c
 
I didnt catch that. I think SOULCLAIMER found why gigabyte gave the UD4 the boot and fixed it with UD4P.. Mabie they should have took it easy with all the usb ports. I have 10 all together.

Also for the hell of it someone leak the f3d bios it states! LOL
 
For those who can't pass Windows loading screen, Have you tried disabling CoolNQuiet ?
 
Soulclaimer, did you had to reinstall ur OS when u switch to f3i?

I wonder when are they going to release the actual release.. i cant wait for it..
 
No but I will;

When I first flashed to f3i everything worked silky smooth but after few hours Vista stopped recognizing USB devices at all and system became extremely unstable.
It logs into windows after 30-40 restarts w bsods and then works @full(F@H gpu+x86) load for 24h+ without a glitch.

I had that kind of behavior with the f3f too.
 
First of all I would like to say thanks to Shadowdust.
Unfortunately, my system won't boot up into Windows with hybrid ACC, but I do not know if my X3 720 is 0904 revision or not (seems like it's not). Is there any way to check the revision without removing the cooler from the processor?

But I have one very pleasant side effect with this f3i bios. I had a problem with my Radeon HD 4830 when during the cold boot it won't let me pass Windows welcome screen and I had to make 2 or 3 reboots and then it lets me in. I was waiting on new ATI's CCC release every month hoping that they fix this problem with no luck. This bios made the trick for me :)

I have a feeling an OS reinstall will definitely help. I was dealing with freezing issues at the Windows load up screen when I first installed the BIOS. It would just freeze and then I would have to reset and then it would work. I would have to do that every time. Finally, I got sick of the problem and figured it couldn't hurt to reinstall Vista. So I did that and updated with SP2 and now it is running flawlessly. I've been testing my USB ports to see if it freezes my computer and all eight plus the two up front have been working flawlessly without freezing and turning off my monitor.

I think this BIOS just doesn't like current Windows installs. I tried loading from a back up image my first reinstall and it still had plenty of nasty freezing and BSOD bugs. Finally I did a true reinstall, formatting my partition as well, and all of those issues are gone.

Thanks dude. :D Although the real thanks should go to G. Skill. After this experience, I'll definitely be sticking with their memory in the future. Who'd have thought a memory manufacturer would help fix my mobo. xD They managed to get to the source of the problem with Gigabyte in three days. This is in contrast to me dealing with Gigabyte for two weeks, only for them not to provide a solution.
