The turbo button selects between two speeds, therefore it can speed up or slow down the machine depending on perspective. As several commenters have stated, many clone brands had the button or indicator light reversed. If the default is full speed then it is semantically correct to say that the turbo button slows down the computer(especially on janky hardware that reverses the indications).
Though I agree that any complete article should explain both situations rather than making half-truth blanket statements.
@@mytech6779 turbo on - normal speed
Turbo off - run slower so old games would run at a normal speed ie. Pac-Man you do not want the ghosts to have super speed around the maze
Great video as always dude, cant say anything but that this settles any reasonable debate about the "turbo button", except for maybe semantic arguments. But the technical side should now be crystal clear to most who has seen this video.
Again, big thanks, these are the kind of videos we need more of.
I thought I was going crazy lol
I somehow managed to be ass-deep in computers through the entire "turbo button" era and never once knew about that keyboard shortcut. I have no idea how I missed that.
Don't beat yourself over this, flapjack. I didn't know about the keyboard shortcuts until now. I had my PC with a 486 DX mainboard and I know how to use the button on the case, not the keyboard shortcuts. I only started to use keyboard shortcuts when during the internet age, although I was taught the 3 finger salute (ctrl + alt + del) by my former neighbour if I needed to restart the computer.

Love your voice as a narrator, you have a unique sound and accent that lends itself really well to it.
I had both a 8088 and a 80286 PC's in the VERY old days. Many games and apps made for XT's were unplayable or unusable on 286's because what you saw was blurred lines or objects by running too fast. Especially the CRT's of the day with primitive phosphors the problem was even worse because it took more time to stop glowing. The turbo button changed the clock to 4.77 MHz . When EISA and PCI buses were introduced you could not change the clock speed that easy
As someone who grew up on DOS, I can confirm that the turbo button on the family PC could switch between 8 and 40 mHz, and it made a huge difference on *some* games as they hadn't coded in a proper 'tick' mechanic.
I remember that the DOS Tetris game gauged the CPU speed during initialisation to calibrate its delay loop (I haven't seen the actual code, just guessing based on observed behaviour). This meant that if you started it with Turbo turned on and then turned it off, you could slow the game down. Conversely, starting it in non-turbo mode and switching to turbo afterwards would speed it up (not what most people would want for Tetris, I imagine!)
There’s a program we would have to run in the hospital when using this DoS based program called ESI. The pc would usually run too fast for it, and it would cause the program to give an error and not launch correctly. We would then have to run a Turbo executable and then it would bring up a window where we had to input a value and usually it would be like 50 and that would cut the speed down to 50%. Maybe that’s why some people think it slows machines down.
I appreciate that the wikipedia article for the turbo button is correct now, and it links to that Intel datasheet for citation.
Google: older computers had problems with software running too fast on more powerful computers. Disengaging the turbo function fixed this.

Anyone else fee like Otacon is narrating? lol, great voice acting skills friend. ❤
Those startup sounds are so nostalgic.
16:04 "Now, let's look at something that people who write Wikipedia articles and tech blogs haven't appearently never heard of: it's called A BOOK!" 🤣
I snorted at that lol
Fun times. Reminds me of back in the day when I had my old 486 system, and managed to upgrade it through 25MHz, 33, 40, 50, 66, and even 80MHz.
It was extra fun setting the jumpers on the front panel turbo display MHz, with no documentation of course..
I remember seeing an arche rival 286 plus computer. It ran at the standard 8mhz and with the turbo engaged, performance jumped all the way to 12 mhz! And it did have the led speed display! Oh baby, it was sweet!😄
Doug Demuro just put out a review of a Chinese car, The BYD Han, which actually has a turbo mode option for the infotainment system computer. It alters the processor and ram usage to make the infotainment system run faster. I guess the turbo button isn’t quite dead yet.
"Proves" is old shorthand for "provides" or possibly "proves itself". Not sure the exact etemology just that I've seen it in old writing going way back (at least 1800s).
The "mystery" of the turbo button was solved at the point of purchase because the function and purpose of the turbo button was clearly defined in the documentation that shipped with the PC's of that era. It was never a mystery and nobody ever ran in turbo mode because we could read at the time.
My grandma used to yell at me if I turned the turbo button on, even though neither of us knew what it did.
I hate to break this to you but they are in fact correct. The turbo button is just a limiter switch. With it in the "on" mode your PC runs normal, as if you didn't have it. With it in "Off" mode the limiter switch is active, slowing the PC as a direct result of the turbo working.
I've never quite understood why this needed debunking, but I guess it's because some folks didn't live through the days of AT clones. Before ATX, there really wasn't a firm standard for things like this. AT clone motherboards often couldn't quite agree on where the mounting holes were supposed to go, sometimes being a mm or two out of place. The turbo button thing was a gimmick and some MBs defaulted one way and some the other. System builders just had to suck it up and deal with it. The fact that AT case designers ran all 3 wires to the SPDT turbo switch so the button wasn't backwards was just a reaction to this inconsistency.
Ooh what a memory. I used to play with the turbo button a lot when I was a kid lol
If not mentioned. I have 2 PCs with the speed display. In many cases that multi turbo connector was also used to piggy back on the display to turn on 2 different speed displays, but that got pretty hairy trying to get all segments to work when you want them. I have mine with 100 MHz Fsb so it displays that, since mine can't go above 199.
When I worked in a computer shop we configured the display to read "HI" or "LO" rather than any numbers.
Very old tradition. Now we have s turbo button on some videocards :-)
3:11 I am pretty sure proves is the correct word, as in “proves faster.” It says the same thing as ‘provides’ yet more convincing. They aren’t saying it gives you a thing, they claim they proved it or you can prove it by trying (buying) their product. As in, subjecting it to a testing process.

one question: how did a person come up with the idea that turbo mode doesnt do what turbo mode does?
Have they never used a Computer from the x86 area? most of them even had led displays for the clockspeed, and yep 66 mhz is faster than 33 mhz...

Heyho! Got a M598v50 Board (probably) and thanks to your video I found the "slow" function via Key Combination (not documented). However the Board also got a Turbo LED. But it doesn't seem to be related to the Hotkey-Turbo. On Vogons someone suggested, this might just be a cosmetical "always-on" LED, which should make you feel better. Any thoughts on it? Any other idea how the LED pin works? (maybe some boards have it active/disabled when having cache active or something like that?)
i knew it the turbo button worked on cpu, i rememebr so well that i played doom(sharware) at school and i used turbo button on and it worked faster, i even remember computer with display of cpu Mhz on too that showed higher Mhz when trubo was on :D
It was never even remotely a mystery to old-school farts, like me. It makes perfect sense seen from the perspective of someone who have lived through that era.
- BTW, the definition of an old fart is someone who just keeps insisting on hanging around, refusing to dissipate 😁
What's up with the TTS thing everyone is commenting about?
Because there was a version with Text to Speech... why else would they say it.

Only 10 seconds longer for the authentic VWestlife narration. I've got an extra 10 seconds for you any day :)
My dad used to turn the turbo mode on when he was doing work in Lotus123.. I told him it didn't do anything for that, but he was sure it made him work faster - not the software, him, hisself.
I'm glad PCs grew out of that phase - the last 3 PCs I've built for him and my mom over the years since the early days were excellent for their needs, and the only complaints they ever had was that they had to get used to the desktop resolution making things look 'too good', and 'not blocky enough', and occasionally they would accidentally 'delete a program' by which they meant they deleted the desktop shortcut. :p
And yet we still find occasional games where parts of the logic are dependent on framerate. Which means some developers spend 40 years and still haven't noticed that different people have different systems with different performance.
I’m just wondering how he thought pressing a button on a computer would make him work

Correct.
Also in the 80s anything with turbo on it instantly made it better in the minds of people in the 80s, you could get some Turbo sunglasses or a Turbo vacuum :)
Great video btw, liked your voice in the video also.
Just like how in the 90s everything got a "2000" added to it to sound advanced and futuristic.

Yup. I was always confused when TH-camrs said that the turbo button, when pushed in, would slow down your machine. I've tried explaining that I would play Wolfenstein on the college pc and the turbo (when on) would run the game much smoother. I was always told to go do my research as it was a known fact that the turbo button slowed your machine down. Even though, like I said, I'd actually lived it XD
@@elemar5 The one in the video does seem to have two sets of contacts, normally open and normally closed, connected to three wires though. In that case, depending on how the switch is plugged in, Turbo mode is either switch pushed in or switch out. Of course that also depends on the board design, whether it expects an open circuit for Turbo mode (like the late 486 and Pentium boards in the video) or closed, like the older boards.
Regardless, when the LED is on the PC runs faster.
@@elemar5 I haven't built as many PCs but still quite a few, plus I've got a background in electrical engineering.
How would that work? The average turbo switch was a plain single-pole switch that connected the two wires when depressed and broke the connection when not. Depending on what the board expected, the CPU would behave accordingly. Reversing the connector doesn't change anything, the circuit is either closed or not and whether the button needs to be in or out for closed is mechanically determined and impossible to change without disassembling the switch.
@@elemar5 Sounds like your memory is a bit hazy. It's impossible to just reverse two wires from a switch and have it go from normally open to normally closed. That's why some have 3 wires. Also the LED will not light up in non-turbo mode by reversing it. A diode does not work that way and more importantly, an LED will not illuminate with zero Volts applied to it.
My mind also went straight to memories of Wolfenstein in high school. I remember the issue with the button not always being in the same position when the light was on. Turbo was definitely smoother. Good memories.
@@Ragnar8504 Regardless of what an "average" (guessing you meant "typical") turbo switch might be, there were switches that could be installed two ways. Since you've got a background in electrical engineering, you clearly didn't actually watch the video, or you'd know exactly how it would work. The switch in the example machine had three wires, in other words it was a dual throw switch. No reversing of the connector, changing which of the three pins of the connecter connect to the two pins on the board.
i prefer your voice to the tts but honestly great job for listening to everyone and remaking the video even when you didnt have to just for your fans. this is my first time watching but it seems like you really care about you community and im excited to become a part of it
My 486 turbo button only had 2 pins, and the motherboard defaulted to "fast" mode. Without the button connected at all, the computer would run at full speed no matter what. With the turbo button connected and pressed in, it would slow down, and this would happen regardless of the orientation of the connector on the header. Maybe it varies computer by computer, but that's how mine is set up, and there is literally no way to configure the turbo button to make the computer faster, the ONLY option for my machine is for the turbo button to slow down the computer
This is exactly the problem we had in the early 90s when I did PC support and new PC builds. We always preferred the Turbo button to be pushed in for Turbo mode and that was the default except when we had motherboards like you mentioned. In those situations we wished the cases said Turbo Off. We provided labels if the customer wanted to change what the case said.
It's the issue of the combination of the case (button) and the motherboard. The whole point of three-wire setup as was shown in the video is that one pair of wires works as "normaly open" and the other pair of wires works as "normaly closed" - that way you could simply choose by moving that connector one pin to the left or right.
However when you have case that has a "normaly open" button and motherboard that is set-up so that open = turbo, then yes, pressing the turbo button (closing it) will switch the motherboard to slow mode. You would have to replace the actual switch in the case for a "normaly closed" one. Or maybe there is an unused pin on that switch that acts as a "normaly closed" pin, so it would be enough to resolder the cable on that end (or move the wire, if there is pin header on that end as well).
@@Tomas_Stec Yeah but the one thing you can't do is make the PC run slower when the LED is on (and that wouldn't make any sense anyway, turbo suggests higher speeds). It might simply be a poor choice of words for expressing the fact that turbo mode was indeed the default speed of the CPU and disengaging it made the computer run slower though. Or someone put it like that and someone else misunderstood it.
@@Ragnar8504 One NOT gate + some stable voltage which you can steal from the "power on" LED and you can have the turbo LED working inversely. OK, it's a bunch of additional components.
@@Tomas_Stec Of course it can be done. Not without careful planning and a bunch of extra parts though, not something that's likely to be done building a simple standard PC.
Turbo mode button reminds me of the amplifier dial that goes to 11 in the Spinal Tap movie, where the narrator says why don’t you just make the 10 louder and use a 10 selector dial.
Had a 486 clone, about 30 years ago. And my turbo button was active when pushed in. And I compared it by turnin' it on and off while runnin' a screensaver. The difference was usually readily apparent.
my 486 had a simple button with no locking function, luckily the case had a built in led panel displaying the current clock speed
We had a 486 too and I remeber it was going from 8Mhz to 40Mhz with turbo mode enabled.
This is definitely a lot better, dude :) .
I was around when the turbo button was used in anger :-) Some early software couldn't run past 8mhz without problems and the turbo button allowed the computer to be slowed down to accommodate that software. Turbo was a marketing term to explain backwards compatibility.
"Proves" can be used in sentences such as "it proves fun", meaning "it turned out to be fun" or "it reveals itself to be fun", so I think what they were saying was "When you do this, it reveals itself to be (an unsurpassed) 60% faster machine than others".
So rather than being a mistake, it's probably just a bit of outdated grammar.
Interesting, I wonder when that change occurred
To make things MORE confusing, on cases with the "speed" display, often times there was NOT a Turbo LED. SO, IF you reversed the 3-wire connector but had the button pressed in, it would show the Turbo Speed, but would actually be running at the slower, non-turbo speed. I had to correct quite a few customer builds because they had the connector backwards!
imagine your modern computer had a turbo button you hit it and windows crashes🤣
@@raven4k998 Funny how PCs went from no speed control to 2-stage speed control to a whole range of possible speeds with software control!
I like how he explains what he is doing because I cannot see but I could imagine what he’s doing. I was born in 1984, so I really don’t know much of those old computers but I do know a lot about Windows 95 and up.
Thank you for uploading this with your own voice. I couldn't stand that other one.
My first family PC was running Windows 95 and had the lock key and the turbo button. I remember the Turbo button would make the machine noticibly louder, so I had always assumed it just sped up the fans to cool the CPU better. This was back in the day with those giant hard disk ribbon cables and case ventilation was basically a meme. 😂😂
I am remembering the sound of those tiny case fans. They sounded like a Cessna taking off at 100 yards.
you have a good voice for videos!! don't waste it on TTS!!
I remember the first computer I saw with a turbo button. Back then most computers booted to DOS and a menu came up first. From there you selected a program or windows if that was installed. Most machines struggled to boot WORD in less that 20 seconds. The first time we booted WORD with the turbo button in the thing loaded in 3-4 seconds. I thought how do they make them so fast. It’s funny to think of that now.
Hilariously Word takes me 10-15 seconds to boot up with my modern laptop.
Yes. Because a lot of software used the CPU itself to limit their processing speed, running at full tilt at the max speed of the processor with no software speed management for whatever processing the program did. hitting the turbo button didn't speed up your computer, it slowed it down. I remember playing with the turbo button on my PC clone and the game Robotron. In slow mode, the game ran properly. At high speed, you'd start the game and the robots would just blink to the middle of the screen and you were dead.
In the mid 90s, at my office we had PCs that, instead of a light for the Turbo button, had a small display that showed "HI" and "LO" for speed. A couple of people at my office argued back and forth about which one was faster, "H1" or "L0" and were astounded when I told them that it was shorthand for "High" and "Low."
I guess they had never used a fan or heater in their lives to not know that!
@@rs12official I've never seen a fan or heater that says "H1" and "L0" in my life. Just High and Low.

My only issue with the TURBO buttons was that they were dangerously close to the RESET button on many cases... Means that when one thought he can just get down to the tower case hidden under the table and push it by memory... ooops... there it was 🙂
That's why we left the reset button unplugged from the main board. You can always do ctrl alt del or power switch if you need to reset.
Remember the old System 7 Macs from the early 90s? Macs did not have a floppy disk eject button. But they put the damn power button right next to the floppy disk slot. Many unfortunate outcomes from that.
I love the idea of people being like "yeah... time for Turbo! Damn it!! No! Not reset!"
One time my reset button got stuck in. I couldn't figure out why my pc wouldn't turn on or do anything at all for a good 20 minutes 😂
Regardless of how the button is configured I always considered the turbo button as a means to slow down the computer because with turbo enabled the CPU is simply running at its designed speed. Disabling the button was to slow down the computer to resolve issues. If the turbo button were designed to overclock the CPU or to enable another piece of hardware like a coprocessor or something then I would have considered it to be an actual turbo button to speed up the computer.
I feel like the turbo button is more akin to a button in your car that would turn a governor on and off for the engine rather than a button that would toggle the boost from a turbo on and off. I just think the button was poorly named.
I appreciate this so much I watched the video again

Thanks for this. I really wanted to watch this but the robot voice annoys me, you're a great narrator.
Oh nice a updated video! Anyways I always likes videos about old computers
I remember mine switched the LED display from 33 to 66
and nothing else
it was not connected to the motherboard in any way except 5v power
I discovered this at the same time as discovering the digits could be set to any digits with jumpers.
I had one in my first PC(a 386dx40) with the turbo button reversed. After I moved into the later 486 and Pentium eras I just put a jumper on the turbo switch as I didn't have any reason to not be in turbo mode.
Why does this show as being a 3 hour old upload? Did you private it and unprivate it? I know I watched it months ago, but why is it repushed as a new upload?
It was unlisted from the start previously, and when you make an unlisted video public, it sets the date to that. (Only happens the first time).
I had my Turbodisplay hooked on my HDD indicator. Set the jumpers to read Hd on the display and -- for idle. Nice fancy effect.
1 hour ago? wasn't this uploaded way before? i remember watching this before, but now it says uploaded 1 hour ago?

I remember watching that creed clip on tv when it originally aired. That's how I know i'm getting old.
one of the mother boards i had in the 80's/90's had a bios switch to set the turbo function in ether direction
mode 1 - turbo switch enabled - turbo light on : low speed mode (default high speed mode)
mode 2 - turbo switch enabled - turbo light on : high speed mode (default low speed mode)
-i can not remember if there where other modes most likely there where
7:33 Thank you so much for clearing this up! I had a Compaq 386 25Mhz in 1992 which included the LED indicator, but it always puzzled me that when pushing the button the PC actually slowed down. Sometimes it just takes 30+ years to solve a mistery!
I had that exact model Gateway. It was a really solid computer at the time. It defaulted to turbo and I basically never turned it off.
i don't recall those sounds on "Memory Checks" rather, that was the HDD Actuator Test - click click click BZZZZZZZZZZZZ
Then the floppy(s) would be initialized and finally BIOS completed its POST and the system would boot.
I've had more than enough 8086, 286,386,486, Pentium legacy machines in my life to know that sound from childhood days up all the way into my professional IT Career now
Hi, another great video
This is like the black magic of computers, being old enough to have purchased C64 new and every other computer almost every second year, then a life time of PC upgrades
I explain to people at the time many games or software was speed sensitive, with 286/386/496 you have the option to slow back to stock XT 4.77m
Nortons info is good, but so it making them play frogger !!
I explain wired correctly your fast machine is full time turbo or fast on , only when you want it to slow down it is turbo off or slow
The first machine that did not have the turbo connector on the mother board was a Pentium 100

See, even in the early 80s people noticed that binding game logic to framerate (which was obviously depending on processing speed) is a bad idea since systems can have all kinds of different speeds.
The closest thing to a meaningful slowdown I've seen is when I disable the caches on my Pentium 3
Oh, and exactly that Wikipedia article now links to this video.
Just want to say that *Aopon* is one of my favorite computer brands.
16:10 - Hey, regarding this _book_ thingie you mentioned - can you please elaborate on how it works and how we can access it? I typed _book_ in the Windows Start Menu search box as well as in the search bar of my phone's home screen, but to no avail. Maybe _book_ is only available on Macs and iPhones? I have a Windows 11 machine and an Android phone, so perhaps _book_ is just not compatible with that. Or do I somehow need to disengage my device's _Turbo_ mode in order to be able to use _book?_
