Product: Prodesk 400 g2.5
I saved an old HP Prodesk 400 G2.5 from the corporate trash heap and I'm using it as a game server. It has the splendid i4590-S processor within. The BIOS has no option to activate turbo boost, and the CPU sits at 3.0ghz all day. Boost flag is set to true in linux. Is there a BIOS upgrade or key combo to unlock the turbo boost option? I tried up, up, down, down, left, right, left, right, B, A and Start, but it didn't work. MOBO is an 8105 Memphis-S.
Thanks!
