Hello my friends, I've got another hard question for you - how do you know which core number is being unlocked? The underlying question is how do you know which core needs a "per core" ACC adjustment? I mean, you could have a two core with working cores 0 and 2 and cores 1 and 3 are locked. You try to unlock them so you'll need to adjust core 1/3 ACC%. Or is it always core 0/1 that are working and the 2/3 are the ones disabled? Is there a way to figure it out? Or at least how do you figure out which core is unstable?

That's something I've always wondered about myself.
Wish I could help but it's the same story here for me as well.

Trying to remember one decade....
My 565BE, from what I remember would unlock core 2 and 3 starting from core 0.
I did overclock enough to damage it from unlocking the 4th core however.
ACC Simply just unlocked all available cores.
Not sure about ACC percentage, all I remember is enable or disable using M4A79 deluxe.
As far as I am aware, the cores that are locked are not promised to actually unlock, guessing there's some kind of damage through the manufacturing process.

That's exactly why I'm interested - to know which ones were turned off and to check their stability and tweak ACC % for them. Well, they unlock in order as far as I'm aware. The ACC function (from my knowledge or experience) simply unlocked the cores. Changing the percentage per core, some claimed stability, I don't recall this to change anything. I mean ACC is simply a debugging channel. I don't see how percentages applied here would accomplish anything. (But that's my opinion more so than fact) From the processors I did manage to unlock and actually overclock, the unlocked cores worked just fine as is BUT required additional v-core to stabilize. Or just ran fine ACC simply enabled. If you take an adventure playing with this, I'd be certain to read it. AM2/+/3/+ was one of my favorite most studied platforms. But much lost through years of not running the platform because I kinda just got burned out on it. Intel slugged on AMD for many years, I finally jumped shit and pretty much run Intel for myself. *shrugs* |

There is no official way of knowing what cores & why they were disabled. But... From what I remember all cpu I have tried Cores 0/1 working and 2/3/etc disabled First it starts with your Motherboard. Not all boards with core un-lockability (ACC) are created equal. Not only does it have to have the ability to unlock cores but to also disable them independently as well as raise/lower the percentages for each core so you can test each cores stability n OC potential Not to just simply enable ACC to Unlock. Because a dual core thats known to unlock to a Quad may have a dead/bad/weak core#3. But if you can independently turn #3 off you may find you have good 3-core cpu. Or if said core is weaker then the rest, say the cpu stock is 2ghz dual core and you can OC the cpu to 4ghz on 2 cores & again on 3 cores, you find that the weaker core will go to 3.5 stable if you have the ability to OC each core independently. I have various boards from each of the big-3 in both DD2 & DDR3 (MSI, Gigabyte & Asus) and they all are different in one way or another. CPU may not unlock on one board but will in another. found that out with my Semperon 130  One example my GA-M785G-UD3H with 960T unlocked to 6 (it was set up already) Its EC Firmware, I have to use Hybrid mode set to Auto, if try to PER CORE with this it will not boot. But on another board (cant remember) I was able to PER CORE and OC each core independently. I can't remember off the top of my head at the moment what boards work best (For me). Sorry I hope some of that helped |

Frank is totally correct.

Thanks Frank! As much as it brings uncertainty it does give stuff to think about too. More complicated than I thought but still worth studying.

Sorry I hope some of that helped Yes this really good explanation. Core 0 always runs, select any other core to produce a dual core or more. ACC - Core percentages Core 0 -12% to +12% Core 1 -12% to +12% Core 3 -12% to +12% And so forth..... Supposedly would bring stability or higher overclocks ect ect. (myths as far as I'm opinion'd) *You didn't need to change any of these for core unlocking. As far as I'm aware, Enable ACC = core unlock (with chips that have them) OR some sort of gimmic stability or overclock "cure" or "tweak" **Per core, chips unlockable or not** I experienced no real changes in my systems, but I ran mostly Asus boards. Core overclocking, per core, works the same with unlocked or cpus that didn't have extra "locked" cores. But man, one hell of an interesting platform really. Had a lot of fun with AM2 90nm Windsors myself. Phenom Schmenom XD. |
