How can you still be playing DA2? That game was so awful that I only managed one play through. I attempted a second go but even after 2 bottles of wine I still could not punish myself into repeating that awful attempt at an RPG.

Roll on Skyrim.

To keep my post on Topic. hmmmm yes I concur could be the Vbios difference. ha!

ok then if it is the vbios why noone managed to fix it so we are all can overclock our gtx460m to 850 ?

@SACH: you made me very jealous :P for now I only put 610/1620/1620 to balance thing out.

Same deal with DA II, I tried to finish my first run and then on the second, I got bored after seeing whats her name? the one whose husband is a templar then she joined the city watch. Maybe after a few more patch fixes, the last of DLCs came out and a whole lot of mods available I will give it another chance.

@expert: maybe because either people got the 5870 or they moved on to the GTX560M or none of us is tech savvy enough :P

One word: Mods

Sach and thief i have a special request for you both: can you dump your GPU bios with GPU-z and share it here?
Also can you post your vbios version, by reading it either with inspector or gpu-z?
I want to check something, if it's not too much problem, thanks.
If it's the bios I would be the first one to flash it to try it out.
My revision ends up with 26.0A which I guess is newer, but it doesn't oc very well.
If the 00.25 version thief has (by reading the screenshot) performs better then there shouldn't be any harm into flashing it with nvflash as card and id is the same.

I've been reading that gpu-z doesn't dump the vbios correctly so..if you two still want to fulfill my request, I humbly ask if you can dump the bios with nvflash instead (nvflash --save vbios.rom).

Also chastity do you know (or someone else) if the gtx460m in g73 still need a modded inf? I've came across a g73jw vbios but seems that verde notebook driver doesn't recognize the card after flash.
It still need a modded inf.

EDIT: well i flashed the g73jw vbios on my g53sw, and it doesnt change much. Max oc is still 814-1625-1628, anything else crashes. That sucks. I just hope that Thief or Sachs vbios have different results but up to this point i doubt it.

Here is my vbios saved with nvflash 5.100.0.1

[Kingpinzero]

thanks Ipnowlan, im gonna flash it now, lets see if it changes something...

[Kingpinzero]

Ok here i am, nope it doesnt change a thing.

So after ive flashed and tested 3 different bios, i can affirm that Vbios is not related at all with the OC potential.
Not at least on my g53sw.
Im thinking that its a voltage issue, or an hardware issue if any.
G73 being bigger probably has a different way to handle the power management, maybe its a matter of capacitors and motherboard.
We can only hope to find a way to increase the voltage on these cards althought theres no way to do it right now.

Here are screenshot samples with FPS of a stock clock vs 810/814 vs 825/827 vs 850. I'm able to manage to get 850 / 1700/ 1625 mem. to stay for about 10-30 sec. before it downclocks. I did this so we could compare how much FPS on Stock clock vs. 810/814 core has vs. 825/827 vs. 850 with 1625 memory. This is on a loaded saved game, so screenshots are exactly where it is. I don't have to touch anything except F10 to save the shot. V-sync on doesn't affect FPS at all, took it off for it's not needed.

As always, View them at 100% Browser Zoom for that's how it looks originally, without getting stretched and losing detail. This is at Chapt. 3 of TW2.
