What happened when you pressed the turbo button?

On most custom-built or no-name PC's, nothing, because they were just on the case and never hooked up. On OEM PC's such as Gateway, they would slow down the CPU to something along the lines of 8 MHz to allow older programs to run properly. Many programs, such as old games, would run unplayably fast on a 3 or 486. So the turbo button ironically slowed the system down to a 286-level speed so they could run properly.

Cool. I didn't know this. I used to have that button. I never pressed it because I had it in my head that the machine would like take off or something.

it went turbo.

>>57136603
CPU came with auto-turbo.

No such thing existed. But starting in the mid-90s, or on some budget model PC's, many OEM's dropped the turbo button in favour of a key combination.

Turbo button is fixing shitty programmers jobs.

Added 150% coolness to the CPU calculations

Don't you mean 20%?

Easy to add 150% because there wasn't much to start with.

Yeah, absolute bullshit. Nearly every pre-Pentium whitebox board was equipped with a turbo switch header, you likely had either an upgraded system or simply a later system built in a case that was also made to fit 486-class boards that shipped with turbo headers until Socket 3 died in 1997.

For OEMs, the opposite is true, most big names ditched the turbo switch after the AT era and did it in software (if they did it at all) barring a few holdouts like Gateway that were pretty much just selling whitebox parts anyway, smaller OEMs did often ship systems with turbo switches however.

Please stop trying to act old on the internet.

It did the opposite of turbo. Turbo was usually the default mode, and it meant the CPU ran at the speed it was sold as. Pushing the button switched the speed to ~4 MHz, the same as the original IBM PC. It was used if you wanted to play some old games (and some other software) that were coded to use fixed numbers of clock cycles for timing instead of using a timer interrupt.

it actually slowed your cpu

why do modern cpus have turbo mode? my i7 can go turbo on all 4 cores and i'm liek WHOOOOOOOAAAAAAA SLOW DOWN MISTER but it won't

That can be arranged. 100 MHz here. This is literally worse than Windows 98 on a 386.

Don't miss next thread: help im stuck at 100mhz how do i get it to go fast again
