that being said, we all make our own decisions and if someone else breaks their stuff bc they werent mindful of what they were doing, thats on them. then next time they get a 600 dollar card they will either cool it better or not push it so hard. everyone has to fry a few pieces of hardware at some point and theres nothing you can do about it.. even though i know your intentions are good. Anyways, have fun guys but be careful of what youre really doing here.

You know, now that I think of it this is a really good point as well. People should accept responsibility for what they do in this regard. Again, I hope i'm not coming across as trying to hate on you fellas that are doing this, because you all know what you're doing.

Anyway, I really can't wait for waterblocks on my cards, then i'll do some test runs at 1.45V redface.gif Both of my lightnings do 1312mhz at stock voltages, one of them boosts to 1277mhz on BIOS1 with no overclocking.....so with that said I can't wait to try 1.4V on water and see what kind of records I can get thumb.gif

can anyone try MSI Afterburner.zip 0k .zip file this file? open afterburner and artmoney, then click table > load and select msi afterburner.amt.
the 00449000 address should appear on the right, and should be editable.
note: afterburner needs to be actually open, with a window and stuff, not running in the taskbar.

Thats just a hex editor right?

If you're into HWBot and extreme overclocking, sure its great, but for the average user (like myself) who uses a PC for gaming, not so much.....or am I overestimating the stupidity of the general (lurkers and newbies) populace? While i'm ALL For overclocking and overvolting...fact of the matter is you shouldn't be using these voltages unless you're on water or if you're going past 1.4V you should be on LN2.....now damage doesn't happen overnight but it definitely does cause electromigration and I have had CPUs die over the course of 6+ months of continuous insane voltages. I've had several i7-870s die, but it didn't happen overnight, it happened after 6 months of 24/7 usage, like I said at really insane voltages.
I think people will try to do this stuff on air, and I think going in this realm on air is stupid. Just IMO. I don't know, I think a large majority of this website is the average overclocker who is overclocking on air or perhaps quite a few on water. LN2 benchmarkers are here but are a minority. For the latter this is a benefit, for the rest....I dunno, I would be cautious.
Maybe i'm becoming an overclocking sissy...i've overclocked and overvolted for years and years but this is a little too extreme for me redface.gif
This is just my opinion, i'm not trying to hate on you guys that are doing this. You all know what you're doing and are aware of the risks, but I just think that newbies will put this info to bad use and harm their wares.

+1

no matter how much you stress that overvolting can damage you card I do wholeheartdly agree that some newbies and lurkers would not doubt not read the warnings even if they are posted so they risk damaging their card.

Its not a matter of the core temperature if you can control the temps.....I think its more likely people will blow VRM's first as they're semi-actively cooled by the fans blowing down from the main heatsink onto the heatsink-plate thing that MSI has under the main cooler. Then electromigration over the long term.

I'm not making much sense:o I'm tired, cross eyed and needa get to bed tongue.gif

the file i uploaded is a format that artmoney uses, it directly loads up the address for you to edit. no need to search and filter and stuff. this method simply takes advantage of the fact that afterburner stores the core voltage offset in memory, and editing that in memory has an effect on the actual voltage. and yeah, any memory editor would work. do hex editors usually come with memory editors? i used to use ultraedit or something but that was long ago and i cant remember all its functions anymore

Not sure what to make of the results. It seems like the voltage increases yield quite a low core clock increase. The card that was max stable at 1330mhz @ +100mv, I ended up trying +148mv for a 3dMark11 run and even though core temp was mid 60C's and VRM temp was 55C, I still got a bunch of green artifacts at only 1350mhz, 20 mhz more with 48mv more voltage and I was getting artifacts.

If you're testing single card you should remove the second card to improve GPU1 temps....SLI will lower your overclocks always without exception.....Also of course always bench with 100% fan, there are other components that may get too hot (excluding whats reported in AB)

I dunno if any of that would help, sounds like you hit a wall

Sometimes its not the voltage its just gettnig the voltage that is more fun.
People WILL blow there cards up with high voltage its just who and when and yes some will kill there cards with that trick.....
I am big on getting voltage into stuff but thuogh the years i'v learned my lesson too many times.
We get greedy thats what always does a card in,best bet in any voltage adding sinairo is to pick a sweet spot that might not be for allout killer 3d scores but has temps clocks and voltage well tuned.
1.36v may to to much given temps for one ,nother it may be 1.43v so it is not how much voltage that may do you in.
Thing is nobody had forced me to do voltage mods it was all me...when you kill stuff take it like a man or **** NO RMA
just my 2c

Oh and it seems some are finding out more aint better wink.gif

Agreed. I've learned my lesson from past mistakes and I think I would never go past 1.35V on air. Heck I wouldn't go up to 1.3V on air except for 10 minutes at a time to benchmark...24/7 no way....

But in the end its all the discretion of the user like michaelrw said.

perhaps some cores react to the voltages differently, ive seen 1550 on 1.4v i think, and 1411 on 1.26v somewhere. my card cant get above around 1370 either, 1.52v (+250mv) didnt do it for 1400mhz on my card. maybe the 2 of us have cards with some serious disabilities. i mean, the artifacting wasnt due to high voltages or anything, my card ran at 1350 on 1.52v just fine..

Yeah I want to see other people's results as well. But mine, like yours, seem to be rather crappy when overvolted any further. I've come to conclusion that this editing isn't worth it, at least for me. The personal best 3dMark11 run in my sig, I had the cards at 1320/6950 and got ~23,580 Graphics Score. I just did another run, with the cards at 1340/6950 (and +158mv blushsmiley.gif), and even though temps were fine, I only scored 23,604. 25pts for an extra 20mhz on each card? No thank you. Unless my results seem strange after more people post how they are doing, I can definitely say on air this edit is kinda pointless.

Edit- Unless the score is lower because of my CPU for some reason. For this testing I just had it at stock speed and with HT off, so, if that would affect the GPU score in any noticeable way, I'm not sure. But if not, then yeah that's a horrible improvement for such an increase in voltage. Not worth it.
