I am currently running the X3 chip with the 1959 Bios, I was thinking of thrying the most current Bios which is v2913 the question I have is do I flash it OVER the 1959 bios or what? I currently run the 1959 on banks 1-2-3-4 and am thinking of running the 2913 on banks 5-6-7-8 just in case it doesn't work out for me, Any ideas, suggestions???
