    Found a tool(MSIAfterburnerVoltUnlock), Now I can set 1.4v(max)
    Anyone tried this value? It's safe?
    What frequency for core is stable with 1.4v?

    Yes i have tried that value 1.4v and its awsome , the only piece of advise i can tell you is that you WILL need to run your card on Liquid Nitrogen using a kingpin Fat GPU Pot Container at -185c , otherwise if liquid nitrogen its not used = instant DEAD of your card ;). Its NOT safe by all means , no air cooler , no water cooler will hold those voltages.

    I Ran my MSI HD5870 Lighning at 1.4v on LN2 at -185c core 1335/1310Mhz

    Thanks for reply. :)
    Man, that's epic overclock.(CPU and GPU) :D
    How about 1.35? It's safe?

    1.3 is max safe imo

    unless you want a dead card!

    Man, you have no clue what sarcasm is, can't use google for some reviews and super long threads about OC/OV of your card and want to OV your card to 1.4v/1.35v (0.3v/0.25v over stock). What have you done the last 2k+ posts you made?

    What crazy overclock are you aiming for with that amount of voltage increase? normal CCC Overdrive is pretty good as is I would say but you can certainly raise the voltages and push further though I recommend studying before attempting this, as the above replies suggest it will likely damage the GPU otherwise.
    (Reading about other overclocks and what they used, technical details and so on like if you need custom cooling solutions and how stable higher values would be and of course what gains it would give.)

    5970 is a dual-GPU card as well which means more heat and it's a bit more demanding so you might not be able to go much further than CCC allows without custom cooling.

    Not entirely 100% certain on some of this but overall I wouldn't just test just because it's listed, similar to how you don't set RAM values (or voltage.) to the max or CPU voltage in bios plus the performance gains are likely rather small. :)

    Tried, but nothing, a lot of sh!t and nothing about 1.4v.
    The forum engine has a function:
    http://forums.guru3d.com/search.php?searchid=2894193
    Yoy can find here, what I posted :nerd:
    So, can you help? No, just don't reply :wanker:

    Hi!
    Just bought an accelero for 5970, that thing with 3 fans :D
    Before, I had stable 970/1250 - 1.3v, now I want >=1Ghz :D

    You don't find anything about 1.9v either 'cause nobody goes to a forum and posts "I killed my 300$++ card with an insane voltage!11!"

    I know it does but how can you make 2k posts in this forum and have like no clue whatsoever about too high voltages for graphics cards?

    I pointed out that this voltage is freaking mad. Should be more than enough to help.
    Still can't decide if troll or...

    Cool story!:puke2:
    I know how to reach 970 on core with "standart" tools, about 1.4... I started this fakin thread and here are some super-overclockers, that post a lot of pics an sh!t, but not in the case.:nerd:
    Only chispy 's post is adequate :D
    I do not ask you to help. There is more adequate people than you.:peeleft:
    So, if you think that I'm trolling, report this fakin thread and GTFO :wanker:

    Thats already a great oc right there. I would also suggest you monitor the temps on the card at those clock while playing something graphic intensive, for some period of time. Run something like gpu-z in the background to make sure your temps aren't too high. Keep us updating on how the new cooling solution works for you :D.

    Even if the card didn't die from that voltage you won't get much more of an overclock with it. At some point you just can't increase the frequency any more while being stable.
