POV TGT GTX570 Bios

Hey there!
I was looking for a bios update for my POV TGT GTX570 Beast Charged Edition (http://www.drivecity.de/product_info.php/info/p746740) but couldn't find anything. Could someone point me in the right direction..if such an update does happen to exist?
Cheers

Btw, my current bios version is 70.10.38.00.70

People usually don't update the bios if they are having no issues with the current version. Are you having issues with the card?

Thanks for replying yassarikhan.
I'll try to explain a bit more in-depth with this post now:
So my card comes factory overclocked: core: 772 (linked with shader clock); mem: 1900; corevolt: 1025mV.
If I raise only the core to 840 and either leave the core voltage as it is or increase it to 1040mV I start seeing artifacts in games like Battlefield 3 and Crysis 2. I have read cases where people have not seen artifacts with the above-mentioned overclock settings. It can't have to do with overheating because my card never ever gets hotter than 70°C.
However if I raise the core voltage to 1060mV there are no artificats to be seen. After I have described my current situation, do you think that raising the core voltage to 1060mV is not too risky and that the artifcats which I saw were caused by an insufficient power supply to the graphics card?
Cheers
ps: I have heard that some areas of the gtx570 series cards can get hotter than others and that capacitors have been heard to blow/fry.

You have to remember that all cards are different. Some will overclock better than others. You can't expect to have the same settings as other people. After you raise the voltage to 1060mV, how hot does the card get? If it doesn't go over 80 C and you see no artifacts than I would leave it at that. I don't think a BIOS update would allow you to use a lower voltage to achieve the same overclock.

Some custom BIOSs give better overclocking than others.

Not sure what BIOS are available to flash your card with though, Google is your friend for finding one though, Trax0r-DnB. Unless anyone here can point you in the direction.
