Biostar TA790GX A3+ unlock 4 cores

[mgshock]

this pics is not my pic, just a user had used the same board. i'd load optimize default with default BIOS
p/s: when i chose Auto ACC and save+restart, my PC going down, doesn't boot ! clear CMOS and turn AC on > ok

Right mate , isnt your cpu 2 cores anyway? Hence the X2. That would explain why the other options for tri core and all cores are not availabe. You have a dual core processor so theres only 2 cores to start with.

so that i should have a x3 or x4 CPU to use core leveling all core ?
can you mod the BIOS, admin ? or add the ACC of TA790GX old BIOS can Unlock by chose Auto ACC ... i don't know much about BIOS

Yes Thats Right , i cannot mod this to do what you want as the available options for core levelling are dependent on the processor installed onto the board.

X2 = 2 Cores Only - Tri Core and Enable All Cores Hidden

X3 = 3 Cores Only - Tri Core Available , Enable All Cores Hidden

X4 = 4 Cores - All Options Including "Enable All Cores" Available

You cant unlock cores that dont exist!

These options are used when for example , you have a X4 Cpu (4 cores) but the motherboard only detects 2 or 3. Likewise if you have a X3 Cpu and the board only detects 1 or 2.

Sorry About That

understood ... ... my 550BE can unlock ! if i use the modded BIOS from xtremesystem,, i can unloc my 550BE, but this BIOS is so boring, cant OC by using BIOS, just use AMD Over Drive only!
so that i hope some modder can mod the BIOS that can unlock CPU by " Auto " the ACC ...
Thanks alot, Admin !

Right ive downloaded the Xtreme Systems Modded Unlocked one but i cant understand why there no overclocking options , as they are not hidden.

hj there, i just flashed your BIOS and my PC working now, unlock ok by "Auto" ACC but it still can't OC by using BIOS, the same like extremesystem BIOS, only diffrent " the way to unlock ". Must set HT Link speed at 1.6GHz and Custom P-States useless ...

[1234s282]

Hmmmmmmmm this is really getting confusing for me now

Both My Modded Bios And The Xtremesystem Bios Sort Out The Core Problem , Nothing Else Is Modified , Everything Stays On Default.

So The Overclocking Options Exist In The Original bios , And Stay There In The Modded One. I havent touched the overclocking options in any way.

[mgshock]

yup, but i can't do anything with Custom P-States, and if i set HT Link not 1.6GHz, my PC going down!

[1234s282]

Id flash back to the original bios and give up right now lol

UPDATE: Found one on Rebels Haven , modded to default options which apparantly fixes HT Link Speed

Follow the instructions to the letter!

Restore all bios defaults
Flash bios
Restore Defaults
Set Ht Link Speed to 1,6ghz
ACC @ all cores
Value(all cores) @ -2%
Core Levelling on Auto

Save Changes
Restart

Also , this is interesting:-

well ,the modification is not guaranteed for all chips,you must be sure if your chip can handle the mod or no

i have two X2 550 ,one of them is good for X4 and the other runs only two cores

Seems like not all the X2 550's allow for 4 cores - seems like a hit and miss to be honest
