No problem
I think you will find that the voltage adjustment does work, you just need a DMM to see the change.

It shouldn't. But then again, very little in life is guaranteed
All that will happen, is that your card at some point in your testing (as you increase clock speed and/or voltage) is that your card will reach it's limit overclocking wise and not go any further. I can't imagine MSI sanctioning Unwinder (the guy who develops Afterburner) to allow an increase that was too high and would damage your card. I suspect +100mv is pretty conservative.
Though as these cards run pretty close to a stock 680 out of the box (main reason I bought it... plus good experience/s with other MSI products), I'm not personally in too much of a hurry to experiment with mine. I will at some point though, if only out of interest.
Only my personal opinion (so no flame war please folks) but I think some folks are getting a little hysterical almost if their card (that's 670/680's in general) won't OC as high as other peoples. Lets be honest, how much is even +100MHz going to give you in games? Though I do appreciate the thought "that if it's free" then why not, or even just for the fun of it etc. Up to individuals though what they want to do with their own purchase/s obviously
Though I'm the first to admit that the games I'm currently playing (single monitor at 1080) are not really stressing this card to it's full even at stock (EG. Skyrim, Alan Wake, ME3). Though I do appreciate there are more demanding games out there that do and maybe these might benefit from more grunt.

No damage can come from raising the power limit, it's just a number used in driver level calculations to adjust voltage and frequency
No disrespect, but this is not what's really being discussed here I think (IE. the power limit.) This card (and the 680 Lightening) does have direct voltage adjustment.
IE. +100mv does actually add this to the voltage. Or so says Unwinder (the Afterburner main man).

If we're talking power limit setting in afterburner it is separate from voltage offset adjustment available on the 660ti PE/670PE and 680LTG, and increasing it cannot damage a card. Being within it sanctions extra voltage, but only up to 1.175v. The extra voltage is added by afterburner directly on top of the current voltage draw after polling it from the card/driver.
If we're talking the core/mem/aux voltage offset adjustment, then potentially the extra voltage can cause issues, but MSI will have tested these and determined the values available to be safe for widespread use.
Basically, you can whack the power limit to maximum and it does sod all.
Conversely, if you lower it, you will limit the voltage(potentially below 1.175v) and boost clocks.
Oh, since I mentioned the polling, The method for voltage adjustment is kind of messy. I would advise saving an overclocked profile and strongly advise you to not tick "apply overclocking at system startup". If you do this you will see that after system startup and opening AB the voltage offsets will be minus figures as a result of the polling. I'm not sure if this will cause issues with the stock operation, but obviously the overclock is lost. I think i read this advice in either a tooltip or the AB 2.2.3 release notes

Thanks for the detail reply. Put much more eloquently than I could
No I wasn't talking about the power limit in post #23. I was talking about voltage offset adjustment.
And certainly not disputing that only increasing the power limit wont do any damage. But then again, I was talking about voltage adjustment. And pump to many extra volts through and I suspect something would eventually go pop. But as I commented earlier "I suspect +100mv is pretty conservative", so can't see this frying the chip myself.
Was not aware of the issue with ""apply overclocking at system startup" I'll have a look in the AB notes and have a go myself and see what it looks like.
Thanks for your input, appreciated.
PS. Just realised why the confusion, because I answered the question "Can increasing the power limit damage the card?".... Where I actually started talking about voltage increases. Put it down to my advancing years

In the end I just could not resist!
Results of my first attempt at OCing.
Using Afterburner 2.2.3.
- Increased power limit to max.
- Increased Core clock by +100MHz.
My normal max boost in Heaven 3.0 is 1,162MHz.
The above changes hence gave me a max boost of 1,263MHz
Ran Heaven benchmarks a couple of times and all looked well.
- Max temp only hit 57C (still quite cool up here). At this, the fan is only running at 42% and anything below 50% can't be heard over my fairly quiet case / fans.
- Power% in Afterburner only hit max of 87%
So left heaven running and went for a cup of tea. Unluckily looking at the AB log, it failed after about 10 minutes (the usual error message that Heaven appears to kick out with an unstable OC). Temp, power% and Core Clock looked OK until it failed (IE. nice straight line). Though just as it failed, the core dropped to 1,020... don't know if that means anything (obviously it's the default 3D speed for this card)!?
So looks like it would require a slight voltage tweak to get a +100MHz bump in the boost.
Can't say that I'm too upset (at all really). Would obviously have been nice to get a core that would do a nice big OC without extra voltage. But that's the silicon lottery for you.
Still a nice card though and more than happy with it
PS. The only thing I miss off this card, is the ability to read the voltage via software. Or failing that, a set of DMM break out points on the card would have been nice (like my 460 HAWK had).

Had another go.
Tried +90 core clock... lasted slightly longer in Heaven loop.
Then tried +80 ... giving a top boost of 1,243MHz and this seemed OK after 40 minute run of Heaven. Though need to do some more testing.
Temp still only hitting 57C max and highest power% only 85%. So looks like that may be the max on the core without extra voltage. And all AB graphs a straight line (IE. no oscillation).
TBC

Just ordered one of these. Was seriously considering a 7970 vapour X, but I do have a slight preference for Team Green, and the MSI was cheaper, so it'll be getting installed tomorrow

I'll be interested to hear how you get on and what your out of the box boost is. Some seen to hit 1200MHz without any tweaking.
Seems to be a bit of a lottery as to what the core will do. But then again, that's pretty much always been the way of it. Even out of the box, I think this card is pretty decent. And in my case, the overclocking potential was not the primary reason for my purchase.
From all the tests and forums that I've read and sad man that I am, I've read pretty much everything out there about the 670 that's going... around 1150MHz seems obtainable by most, with something like 1250MHz with a bit of tweaking. Some get higher, some lower. And that seems to be the way of it across all the manufacturers. Not convinced that any of the manufacturers do any really effective binning, or cherry picking etc. Just need to look at the ASUS TOP fiasco to see that. Though quite aware this is a nice card and it was on my list when I was looking.
Enjoy

Looks like the voltage adjustment definitely works for this card, there's been some dispute on other forums (EG. overclock.net).
Tried +100MHz on the core again but this time with +20mv and this has just passed 2+ hours of Heaven 3.0 at highest settings. Where it would not last 10 minutes without a voltage bump. Think I'm happy with that at the moment. Solid boost to 1263MHz and temps still only 57C max (though a bit colder up here today).
Think I'll play around with the memory now.

running at stock, got a peak of 1241 core, but usually runs around 1150. not tried clocking it.
anyone found a way to quieten this card down before getting into os? and i know about the dust removal phase for ~30s.
making bios changes has the fan at about 100%

Looks like you got a good card. Mine at stock "only" hits 1163MHz.
As far as the fan running at 100% in reverse at startup. As far as I'm aware, this can not be disabled. Can't say it bothers me too much, and I know it says it runs for 30 seconds... but mine stops doing it when it gets to the Windows logon screen and for me, that's only some 18 seconds! I'm making a guess here, but I think it stops doing this when the drivers load. As if you try and run this card in safe mode with just the VGA drivers installed, it seems to run at 100% all the time (well it did for me).
PS. Not quite sure I understand your final comment "making bios changes has the fan at about 100% "??? or is this a reference to what I've just said above about the fan running at 100% until the Nvidia drivers load?

1189MHz on mine on the core during Haven. Happy with that, but the card is quite loud. I'm used to the Accelero Twin Turbo 2, and the 670 PE is like a high pitched hoover compared to that.
Still, small sacrifices and all that.

Another decent boost (damn... both higher than mine
)."but the card is quite loud." ... really? what fan % is it running at under load? I suppose ambient room temp comes into this, one advantage of Scotland... is that it never gets warm up here
Mines never gone temp wise over 60C (in games) and at that it's running at 43% and anything under 50% I can't hear over my pretty quiet Gentle typhoon case fans (but I am getting on a bit ). Though never obviously experienced the " Accelero Twin Turbo 2".

when i start my system up and go to bios the card is 100% reverse for 30s, there is a dip in volume but then resumes at 100%.
getting to windows is a similar time so doesn't normally bother me, was just wondering what actually quietens it down?
e.g. if went to linux would it run at 100% until X is started (when graphics driver starts) or would it eventually quieten down on its own?

Only guessing, but I think it's when the drivers load. As I don't think it's a fixed time myself. I've timed it myself with a stop watch and definitely for me, it's some 18 seconds and that coincides exactly with the Windows login prompt appearing.

Well, I have to be honest, my case is a shambles and I'm getting a new one on Thursday (going for the Corsair 600T White) which should quieten down things somewhat.
In Guild Wars 2, the card is getting upto 74c at 57% on the fan (auto). I've tried setting it manually at 60% but it's quite noisy then and it only shaves a couple of degrees off that temp so I've decided against it.
It is warm where I am (South East coast) and the room the computer is in has a warm ambient temp, so there are a few things to take into consideration.
Got just under 18990 in Haven 3.0 on OcUK settings with the card on stock, which was a bit of a step up on the 11k I got on the 2.5 at a lower rez with my old 470, so happy with the performance
