I'm looking into upgrading my cpu and I want to know about updating my mobo bios. Currently its 1014 and I am running an AMD Athlon 64 3200+ Venice Socket 939 CPU. Is there any other items or processes I need to take care of before I purchase and install the new chip. I am looking into getting the AMD Opteron 170 or 175. I was also curious are there any methods within the mobo settings that I can increase the amount of mem my system uses. I have just installed 1gbx2 which brings me to a total of 4gb.
