GTX 670MX Overclocking [Updated-custom BIOS file] - Page 9

post #81 of 658
There is another guy that has raised voltages of these cards, (he requires donations) but from what he was saying is that voltage unlocks have to be fixed rather then letting the user raise. He is Svet on the MSI forums. And I think that the max voltage for these chips is somewhere around 1.01v or something like that.

He's selling the software for almost 20 bucks, about 19.50USD I think, no thank you- you have no choice but to donate if you want to use his software, so in reality he's really just selling it, the donation thing is just there to make it sound good I guess? and no it doesn't support Mobile kepler cards yet, at least not the GTX 670MX and 675MX, at this time the only way to modify these gpu's is via hex editor_, but Kepler Bios Editor (KGB) is completely free and works just as good as it supports a lot of the GPU's (mostly desktops) Mobile GPU's are still very limited and it still doesn't support mobile kepler cards_

There is a Chinese guy on one of the chinese forums who has been able to overvolt this GPU but he was only able to do it with all P-States set to 1.0v, so even when the card downclocks it still sits at 1.0v_ I don't want that so I'm trying to find a way around it because having the card at constant 1.0v is just having unnecessary power draw and heat.

Yep that is why i didnt bother with that guy. I know that SLV7 over at techinferno was working on a voltage unlock, but I am not sure if he ever got around to it or not.

Ok here goes,
With thanks to httuner I have hit the 21000 mark in vantage. But ive cranked it down slightly to give me a more comfortable overclock so I don't need the Turbo Fan operating. I wasn't able to get to 1300Mhz memory clock as previous posts have achieved, probably due to cooling, or different driver as im currently using 314.21 using modded INF from laptopvideo2go on windows 8. Its hovering nicely at a max of 60 degrees centigrade so I know this card can go further, but I think its either the brick, or the Video voltage which is restricting me. I have updated the firmware to the unofficial MSI version to turn off throttling which was supposed to increase temperature, but I havnt seen an increase. And to be fair this is the coolest card I have overclocked. I am hitting 680m stock easily without stressing it too much and I know it can go further. Its just having the bottle to do it. lol.
Ok here is my stable GPU-Z screen shot

and here is my 3d Mark Vantage screen grab


Im not getting near HTTUNER but im quite happy with what has been achieved today so far using the modded Vbios.

Here is the 3dMark 11 shot


The core clock will go further so maybe just maybe later I will give it a go

Thanks again to httuner

That is a high overclock! 990Mhz I didnt think was possible for 60C. Are you running full load constantly? Or just for the 3dMark11 Bench which takes breaks between the runs. Im curious to see what heat you get after about 10 minutes of something like The Valley Benchmark or Heaven Bench.

http://www.3dmark.com/3dm11/6259533 1006 MHz, max core temp 56-57 when I did benchmark!


new bench: http://www.3dmark.com/3dm11/6261289

same core speed.

Yea, mine only hits about 60C too when i do 3dmark. But the tests are only like 30 seconds long so its barely long enough to even heat the heatsink up, fan doesnt even really have to be on. Im talking sustained temps when gaming full load. I think mine is hitting 70C sometimes 71C at 927Mhz. Which seems to be my max with the voltage set to .925v. Bench mark scores dont really get you much if you cant game with it.

gaming bf3 ultra, only 60-61 celcius.

sunza that is awesome! You should post a screenshot of that showing a full load 1006Mhz and 60C! Afterburner monitoring or something. You must have good cooling!
