I have a 5 year old Desktop PC at home. I recently got Windows 10 installed and bought a new 1TB HDD. I got few games such as Dota 2 and Far Cry 3. Both run at less than 20 FPS. My processor goes up to 70C and 90% load while gaming. I'm gonna get a Graphics Card, dual tower heatsink and chassis fans soon. But I wanted to overclock the processor.
I have
-Intel dual core E5400 2.7 Ghz processor.
-Zebronics G-41 socket 775 mobo
-American Megatrends BIOS (2012 or 2013; not sure).
-1TB HDD.
-4 gigs of DDR3 RAM.
My mobo bios oem is locked, I can't find and options to increases voltages in the bios settings.
How do I unlock the OEM, and overclock the processor. Also any tips for better performance for a very low budget.
 
Solution
No amount of overclocking is going to help. You need to upgrade to a newer platform, Haswell i3 4370+a cheap h81 motherboard will support your memory, and should be enough to power a R9 380 or an overclocked 960 just fine.
On my old Gigabyte G41+E5400, with adequate cooling for the cpu and vrm's, I set the multiplier to 13.5, FSB to 266mhz and cpu voltage to 1.4v.

This will give you a 3.6GHz overclock and should be stable, slowly reduce the cpu voltage until you get issues, I got down to 1.38v.

May extend the life of the PC for a year until you do a cpu+mothboard

If as you say BIOS is locked though, your out of luck.
