So you've dialed in your overclock on your gpu and you know the max you can overclock and have 100% stability. Getting tired of that same utility needing to run every time you boot up to reset your gpu to the overclock you set and slowing down your boot-up time?
Maybe it's time to flash your gpu bios. Flashing your gpu bios will allow you to essentially set your overclock as the default clock. Another thing you can do is set the idle clock and 2d clock even lower as to conserve power or you can flash your bios to change the default fan speed whether you want better temps or a quieter system.
If you want to do this and are tech savvy then continue on.
1.The first thing you will need to do is go through my "http://www.tomshardware.com/faq/id-1865878/edit-graphics-card-bios-nibitor-gpu-note-work-nvidia-cards.html Tutorial on editing your bios.
2. Then you will need to make a bootable usb or floppy. here is my how to make a bootable usb guide: "http://www.tomshardware.com/faq/id-1869892/making-bootable-dos-usb-drive.html"
3. now that you have those set-up you will want to create a file called autoexec.bat on your usb drive. open it up in notepad and enter nvflash -4 -5 -6 "Name of your edited bios"
*enter your edited bios's name without the quotes
4. Then download nvflash from here: http://www.techpowerup.com/downloads/2258/nvflash-5-142-for-windows/
5. Now copy the nvflash.exe to your bootable usb
6. Now you will want to copy your newly edited bios and put it onto the usb as well.
Now you should have these three files on your bootable drive and possibly some other system files depending on if you have hidden files shown
Now we are set to boot from the usb. Be ready for a dos experience not many are familiar with anymore.
7. When you boot from USB and you are at the dos environment type in nvflash
If you got here then you are dialed in and did everything correctly.
Now type in nvflash --index=1 -5 -6 "Name of your edited bios"
enter it without the quotes and then hit enter.
If you did everything correct it should give you a few chirps from your system speaker and it will tell you that the video adapter firmware has been updated. Once you are positive that it has correctly finished because of these chirps you can restart your computer and check it out in gpu-z to make sure that what you wanted to happen happened.
