So i just started mining and learning a little. I have a Nividia GTX 760. I know it isnt much, but I just want to play around for a little before I spend any serious money on mining. Ibtried to set up to use my gpu in minergate but I got a message that the memory was too low. I did some googling, and read that you can increase dedicated memory by entering BIOS and altering it to make it higher. I wasn't able to get into BIOS by using F2,F5,F8, delete etc. How would I do that? Is there any other way without buying a new GPU at the moment? And if not, what would be other alternatives for me to do a little mining until I am ready to spend on a nice big fat rig? Any help is much appreciated.
