    Default Radeon HD 6950 can be unlocked to HD 6970

    Looks like Santa brought an extra present for us hardware enthusiasts this year. Thanks to a less secure locking method AMD's new Radeon HD 6950 can be unlocked to a full blown HD 6970 with a few mouse clicks.

    As detailed in our article, you can safely perform the flashing process from within Windows. In case something goes wrong it is easier than ever to recover the card thanks to AMD's new Dual-BIOS feature.

    We tested the unlock on three HD 6950 cards: one AMD engineering sample, one HIS media sample and one ASUS retail card. All of them unlocked perfectly and run at HD 6970 speeds now.

    nothing new, ppl were doing this since the 4850. The good thing is we can buy two 6950s flash the bios and CF them for kickass performance for 2/3 of the price.

    When your talking a measly $80 more for a card that is guaranteed to do what your taking some [not many but some] risks to force another card to do. I personally would spend the money.

    That was the deciding factor for me.

    Plus there was power consumption issues, the forced cards run the risk of getting to much load and not enough power for lack of 8 pin. There have even been a few complaints about artifacts, but you cant believe everything you read right? Plus do they not Bin the GPU's just like they would a CPU? So just the fact you bough the cheaper card built on the exact same platform means your material was inferior to begin with?

    It just makes more sense to spend the extra $80 for a card that is not going to possibly have issues. in my humble oppinion

    Regardless I too am very interested in how your overclocking attempts turn out. I am still nailing down my cpu clocks with Deton's help so i will not have a chance to start toying with the card for a little bit. Plus I want a get a cooler on it first i think too. I hit 90C gaming the other day at stock clocks. Apparently they are rated to 100+ [cant remember, I think it was like 104C] but that's way to hot for my liking so I would like to get some real cooling on it first.

    I have read that the accelero xtreme plus fits and the "Thermalright Shaman, if you don't mind giving up 4 pci slots." to quote from another thread I just read on OVERCLOCKERUK.

    I would think that the smartest thing to do if unlocked 6950 to 6970 would be to not OC as you are probably pushing the card to some extent just by unlocking it. From what i've heard the GDDR5 is slightly different in the 6950's than in the 6970's, i too am very eager to see how the unlocked 6950's OC as I will have a pair very shortly. I'm going to look into the different GDDR5 heresay tonight before my 2nd arrives. Hopefully its just that, "heresay".

    Just use Trixx(Sapphire) or MSI afterburner. To unlock the voltage control in Afterburner, you need to tweak the .cfg file. Give a shout if you need to learn how.

    please do tell. I do not have the 6950, i have a 6970, but i have been having a hell of a time getting it to overvolt with any program. I even flashed a ASUS bios on the #1 bios position and it still will not let asus smartdoctor even touch the voltage.

    Is it just the 6950's that will do it? I was under the impression that all the first 6970's were reference versions. So i wonder if the tweaks your talking about are what I am missing.


    I changed the option in afterburner config that allows you to clock higher but that's it and it wasn't enough. And usually if the card doesn't support voltage modification all it tells you. In my case it doesn't say anything, lets me move the slider, but doesn't apply the voltage adjustment. I have all 3 of the boxes checked in settings also.

    I'll be sure to try that drdeath. I am much more comfortable oc'ing and flashing these new cards as there is a built in 2nd bios i can revert back to at the flip of a switch incase i somehow manage to screw up flashing the new bios. I have yet to do serious OC'ing on a GPU other than simple ATI tools + Artifact checker. Trixx works well then? I'll definitly check it out, and i would definitly need a general idea of what/how to tweak the .cfg file to unlock voltage control. I read somewhere that modding the card and adding +20% (power?)(oc?) will match a modded +20% 6970 while consuming far less watts but they did say something about changing the voltage so that the safety specs won't kick in and reduce the cards performance. I'll check out Trixx and let ya know where i'm falling off the beaten trail.

    P.S I found the site i read up on modding/ocing the 6950/6970 here it is! hopefully this is what i will find as i mod/oc my card.

    Is it just the 6950's that will do it? I was under the impression that all the first 6970's were reference versions. So i wonder if the tweaks your talking about are what I am missing.


    I changed the option in afterburner config that allows you to clock higher but that's it and it wasn't enough. And usually if the card doesn't support voltage modification all it tells you. In my case it doesn't say anything, lets me move the slider, but doesn't apply the voltage adjustment. I have all 3 of the boxes checked in settings also.
    trixx should allow voltage control
