Can updating BIOS make computer faster?

[john88]

Well I decided to update my BIOS for the first time on my Z77 ASRock Extreme4 with stock i5 3570k. After updating, I noticed my CPU load drop A LOT. Running 5x bots, the load was usually 50%-85%. Now it's throttling as low as 30%-60%. So I'm wondering if a simple BIOS update can make a computer run faster, is it possible?

I also installed a CM Hyper 212 Evo cooler yesterday, but I doubt that did anything, because I didn't notice any difference until after I updated the BIOS today...

Depends on the update, it could make it run faster in some cases yep.

Wouldn't recommend trying it if it isn't necessary though.

Agreed. I always google before plunging into an update, because of the rule of "don't update what is not broken".
My worst bios update bricked several of my HDDs

You probably had wrong settings in there before and the update reset everything to default.

Everything was default, except some fan speed settings. Exact same settings after updating too.
