Hi All, new here and just replaced my HDD with Samsung 850, but am not able to download the fix due to pre-promotion. Aside from installing and tweaking configs as guided by google, I really am not familiar with the terms, so can anyone help out a helpless soul for below queries? -how will I know if am actually R1 or R2? -how will I know if am A08 or A05? -what does unlocked A08 mean? what do we intend to accomplish from unlocking a bios? -what does overclock mean? Why do this? -does anyone know how to selectively have the fan run and not? I just want it to run (and yea its fan noise on and off) only when I play Dota2 -And how do you exactly measure 6gb/s speed? Appreciate anyone teaching a "kid" the basics.
