Probably a dumb question but i am new to the building scene and am trying to learn. If i turn the ACC to auto and cant boot does that mean the 4th core on my Phenom II 720 is defective? I have a Gigabyte MA790GP-UD4H board. Also can you tell me how to have my build listed so everyone can see it when i ask more of my many dumb (lol) questions. Thanks all

I don't know the answer to your ACC question, but what part of your build list cannot be listed.

Raidmax Smilodon case Phenom II x3 720 4GB DDR2 800 Gigabyte MA790GP-UD4h WD Blue 640GB HDD LG GH22 multi drive Raidmax 500 Watt psu No video card yet(dont ask)
vista premium 64 , look familiar?

Why yes it does ! I just didnt know if it was showing up or not. I have had people ask what my system was so i wasnt sure. Thank you. Should i ask about the ACC in a different forum?

I think you're in the right place for your question, I just don't the answer but hopefully some wise old soul will chime in soon.

Thank you. Everyone has been EXTREMELY helpful for this newbie. I wish i would of started building a long time ago. Thanks again.

Assuming that

A) It boots fiine with ACC turned off and

B) you've verified you have a version of the BIOS that will perform unlocks

I would say yes, your 4th core is kaput.

i have the F1 bios. i know there is an F2 bios on gigabytes website but i am a little nervous to flash it.

You should be OK, I have not used Gigabytes flash utility since way back when I had a Socket A rig with a dual BIOS thingy (technical term) and it was good then so I can't see having got worse.
May 27, 2009 8:17:51 PM

So you think i would be ok if i flash it? Should i just do it from the Gigabyte website?

Better doing it from DOS mode, by using either a floppy or usb stick or maybe a cd. Why? Because it is more safe in Windows there are many things that can ruin the flash and if your flash is ruined then you will need to either reflash or get a new bios chip.
May 27, 2009 8:26:54 PM

Or I don't know if you can flash Gigabyte boards from DOS, but maybe you could also flash it directly from BIOS?
May 27, 2009 9:04:07 PM

I dont know how to do it :(  either with a usb or a cd . I dont have a floppy. I see a bios flash option on the Gigabyte website though. Man i dont know. Maybe i should just leave it be. I'm not having any problems but i sure do want to try and unlock that fourth core.

If your board supports Q-Flash then you can do it from a USB flash drive. iirc.

Well a BIOS update will NOT help your unlocking potential. Newer BIOSes have had fixes written in to prevent core unlocking.

Well that sucks sweaty donkey balls.
May 27, 2009 9:38:03 PM

Big sweaty ones !!! Is there anything else i can try to unlock it? I think i am just gonna leave my bios alone for now. If i turn to auto and it doesnt work can i just turn it off to go back to where it was?
May 27, 2009 10:00:02 PM

Should be able to. As a ? are you certain your motherboard is a confirmed unlocker? I know theres only like 4-5 motherboards it works on, not sure which those are tho.
May 27, 2009 10:12:49 PM

No, not certain. Is there a way to find out ? Seems like i have read of it being done on the FX-UD5P boards though.
May 27, 2009 10:16:04 PM

Actually just read in Tweaktown Forum that someone has done it.
May 27, 2009 10:22:46 PM

Did they mention which BIOS they had? Theres a possibility that F2 was the initial AM3 compatability BIOS and would therefore have the unlocking ability.
May 27, 2009 10:39:44 PM

It says they have the F2 bios.
May 27, 2009 11:39:03 PM

You can try to unlock you X3 720 by a bios setting called "Advanced Clock calibration"
Set it "Per Core" With a setting of "-2" per individual core. If that doesn't work try "0" and try again.
Play with the settings. And torture test with Prime95 for stability.
If you can get it to work stable you are a lucky man. Mine unlocked but failed the stability test @ default speed. :( 
If it won't even boot you core Is probably defective as such and you will have to set your setting back to disabled to reset. I unlocked mine with a MA790FXT-UD5P. With the F2 according to Gigabites Bios info for you mobo it should be possible to unlock your core, but I am not aware of any reports regarding attempts with your board.
The X3 720 is a great overclocker with setting "Advanced Clock calibration" to disabled. And is a fine processor for it's price.



With the F2 according to Gigabites Bios info for you mobo it should be possible to unlock your core.

Good luck

how the hell do you get the ACC? got the same mobo as you do, yet i don't see the ACC option in my BIOS, do i have to press something or what to get it to show up?
May 29, 2009 1:15:46 AM

If you hit Ctrl & F1 after you enter your bios you will the pc health move to the right side and it will be under M.I.T.
May 29, 2009 3:25:21 AM

???
can you be more specific? like, CTRL+F1 on the first BIOS screen or the M.I.T. one? please specify. Am i supposed to hit CTRL+FI, then press enter?
May 29, 2009 1:00:38 PM

Yes. CTRL+F1 on the first bios screen. Then hit enter on the M.I.T. ACC will be the first choice.
May 29, 2009 1:01:08 PM

Let me know if it works. Also what bios do you have ?
May 29, 2009 4:30:17 PM

yea, i can see ACC, but does that mean i have F2 or F3? how do i know my BIOS?
May 29, 2009 4:36:02 PM

In Vista it shows under System information
May 29, 2009 5:08:56 PM

uh, my bios is F3, can i unlock or no?
May 29, 2009 7:28:25 PM

Hmm, unknown, you would have to do some googling and see if F3 supports unlocking. IF not, you can risk a backwards flash to F2.
May 29, 2009 8:59:57 PM

how exactly do you "downdate" back to F2, if F3 doesn't work?
tried googling it, not getting any specifics, does anyone know if F3 can unlock it or is F2B the only one? if so, how do you do an downgrade?
May 29, 2009 9:55:21 PM

I dont even know how to update mine yet ! im kind of scared :(  So i cant help you with downgrading. Sorry
May 29, 2009 11:13:55 PM

Its the same process as doing an upgrade, you just flash with the F2 bios.
