well here it goes, I recently built a new system based on x79 chipset – it boots perfectly very responsive and lightning speed but the problem is this: once I make any changes in the bios let's say lil overclocking, voltage tweaking, Dram timings…etc. it will boot again with the same settings I entered BUT (BUT) once I turn off the system (Unplug) the power cable from the socket ALL settings and I MEAN all settings including the clock, date, bios setting resets to factory default??!! Even the clock shows date as 2005??!! Please help meeeee???
System Specs: CPU: i7-3820 MOBO: Asus Rampage IV Formula Ram: Corsair 16gb 1600mhz SSD: ocz 128 GPU: GTX 680

That sounds like one of two problems:
1) defective or missing battery (the battery on the motherboard is for remembering your BIOS changes)
2) the CMOS reset pin has the jumper on it (some motherboards have two pins which you then jumper together with the computer off to reset the BIOS to default)
My guess is the battery.
a) check the voltage, or b) buy another battery, or c) borrow another battery (you'd have to redo the BIOS settings if you take it out of another computer)
I really was thinking about the battery few minutes ago (what the odds??) I have couple of batteries laying around I will change them if it works someone is getting a best answer
