In this video we will be having a look at overclocking. At first I will explain in a very simple way what overclocking is and then I will use this technique in order to speed up my Arduino Microcontroller and GameBoy! Along the way we will learn about the advantages and disadvantages of overclocking. Let's get started!
Thanks to Altium for sponsoring this video.

Hi there :-) Thanks for watching my last big video in 2021. This year has been quite a ride. I hope you enjoyed the videos I put out and you are looking forward to my videos in 2022. I wish you all happy holidays and stay creative ;-)
Dir auch! ;-)
indeed, hope the new year will be more crazier (in a good way) than this one
I hope you enjoy the holidays and thank you for the great content.
Thanks a lot for your instructive pills, on my behalf and on that of my students in IES Cavanilles - Alicante, Spain. See u next year!
Very cool project! 👍
Also to deliver the higher current you need higher voltage, so “overvolting” may be required to achieve bigger overclocks, and with higher power more heat gets generated
True :-)
Water cooling an overclocked Gameboy? Sounds like an LTT video
@@colejohnson66 Anthony from LTT needs to get on it!
That's exactly why I have a 50L dewer of LN2, a single stage phase change unit and watercooled tec's !
It's nice watching a 400w 12900k OC drop to 250w with just a bit of cold
Well they did overclock a calculator to run some games on it, and watercooled it if I recall correctly
A bit more info on the gameboy. The gameboy color that you're using actually has twice the clock frequency as the original gameboy (8mhz vs 4mhz). So to compensate, the GB Color uses a clock divider internally, unless a game specifically tells it not to, which most gameboy color games do (Unless it's one that is designed to be backwards compatible).
If i remember correctly, this clock divider is causing the glitches as it can't keep up with the higher frequency and "misses" clocks. If you tried a gameboy color game, it might be stable at much higher speeds. Also another source of glitches might be the ROM, as higher clocks may push access times below its latency limit. A modern flashcart with flash or SRAM based storage might fair better.
Also interesting is the world of emulation, since you can essentially modify the way the hardware works. For example, some time ago i modified a GB emulator to run at 160mhz while keeping sound and video hardware at stock speeds. This means that the gameplay runs at the same speed, as it's tied to the display refresh rate, but any sort of slowdown is completely eliminated because the gb essentially has 20x more CPU power for every frame. This is great for chiptune artists too, as some of the more advanced effects can be quite CPU heavy and overwhelm the device.
Thanks for the feedback :-) Very interesting
@@greatscottlab Thanks! Awesome video btw and great explanation of syncronous electronics. Also I honestly had no idea that clock crystals output a sine wave rather than a square wave. Interesting, i wonder if that can cause issues on chips where the voltage edge between 0 and 1 is a bit fuzzy.
@@BinaryCounter seems to be a dimension biproduct of how the universe works... If oscillators oscillate, it's more likely due to some "spin" hence the sin wave. My knowledge is very limited but afaik this is why when using Arduino switches and stuff, one works with pulldown resistors and threshold voltages etc, as the voltage at a pin might be unstable for a number of reasons...
The clock divider makes sense, since it plays OG Gameboy games too.
I saw a video years ago where somebody overclocked the GBC. They found that if running a CGB game the system crashed at half the input clock as needed to crash a DMG game. Basically it's the CPU which is glitching out, and the divider is working fine.
"It is a bit precious to me"
As someone who restores broken gameboys that have long been forgotten, I felt that.
wow, this was a nice video,i really like these kind of experiment videos they are awesome. tbh i have never owned a gameboy, but i have gotten into retro consoles over the past years and its really amazing to see that changing the clock frequency doesn't abruptly freeze the device, well there it is an undetectable hardware speed hack.
Glad you enjoyed!
Why would it need to be undetectable though? It's not like any games check for this.
If there were a game that wanted to though, it should be able to find the clcok frequency since the DSP knows how to change the pitch based on the clock.
RETRO CONSOLE!!!!
I feel like having a heart attack....
@@MrEmrys24 ???
Please don't.
As well as overclocking, this video is a great way to understand what a clock signal does in all sorts of standards in digital electronics. Great video, Scott. Thanks.
The madman actually brought the timewarp from Gameboy emulators to the real deal, what a lad
was looking for this comment
@@timng9104 me to lol .
It was fascinating to see the effect of oscillation frequency on gameplay like this. Thank so much!
I'm always amazed by your typography and drawings, very clean!!
Your videos are always very informative and fun to watch, thanks for taking the time/ effort to share them!
NONE of all your mesurement equipment and tools can tell how much i enjoy this video. GREAT SCOTT!
Thanks for all your videos! Even though I have a computer engineering degree, your vids are still extremely helpful for tinkering on my own. Happy holidays and hope you continue with all your work.
A very educative project! Merry Christmas!
Always heard about overclocking. Never really understood how it worked until now. Thanks for teaching me something new.
Thank you for all the great videos this year I can’t wait to see what you do next year. Happy holidays
Thank you and happy holidays to you too :-)
Great video. I already did this last year with my Gameboy DMG. Build a little switch for it and I could swap between 2 static crystals. Gameboys are fun things to tinker with.
Nice work!
Sounds like an awesome project, might try something like that!
I love your videos so much! These need to be shown in schools!!!
Loved watching your videos and will continue this in 2022. Happy holidays sir.
3:30 that's quite a lot of cold solder joints on that arduino lol.
I saw that too! They do the job, indeed, but I expected something better from you, great Scott!
nice to see you put it back to original condition. very good info in this video. and you explained brilliantly as usual.
Excellent!! never thought someone can actually overclock these things. This was fun and informational to watch.
Bc of work I couldn't find time to watch more complicated video's like your electronic video's so today is the first time i saw your new intro and It's pretty cool, I love it
This guy is really smart and his videos are well presented. I hope he gets more views back for 2022.
You are so supportive and informative... Thank you for the work you are doing.....
Awesome video, thank you! Very cool to see my childhood handheld be sped up like that through overclocking.
A clever idea, and one of your very most informative tutorials! Thanks, and keep up the great work GreatScott!
Great stuff, very interesting indeed. Thank you for another year of great videos, lessons and examples to inspire us to tinker and create. Happy holidays and best wishes for the new year
Thanks you for your experiment with crystal resonator!
All electronics and explanations aside Your ✋ writing is wat made me to watch your videos
Glad to hear that
I LOVE this theme and the new intro! Many memories were had for me on the gameboy advance sp playing the original pokemon yellow. And the Gameboy is what got me into electronics to begin with. You helping me learn electronics is just awesome with this video.
Your work always amazes me thank you so much for all the knowledge you provide us
I always learn something cool from your videos, keep up with the cool videos
Hey I really enjoyed the video. It was very informative and I learnt a lot. Keep up the good work!
Awesome man! You've added fast-forward and slowmo modes to the gbc.
All of us love this tiny gameboy cause all had one in our baby years . And we didnt think one day can learn all inside it , but really wanted to tear it down 😁😁 thanks . I'm from lovely IRAN . Hi to German boy
I grew up with Gameboy color! I really liked this video 🍒
The new intro is crisp. Well done.
Love the facial hair , equipment , and your content over all ,
This was my favorite game on my favorite version of the gbc. It was great to see
One Of the most important experiments for mankind's inner child. I love it. Thank you
That’s actually frikin awesome Scott. I have a situation where I’m tryin too over clock an older tool I got from my dad because it is built like a tank but just a little too slow too work on modern electronics lol. I didn’t realize that the square oscillators were actually micro controlled lol.
I'm not an electronics student, I do not even know much about electronics, I specialize in chemistry, I watch your videos because I enjoy your handwriting when you write a booklet😅👏🏼👏🏼
I really like seeing how you debug circuits, like identifying the oscillator at 8:00
A slight correction for your video: at 5:24 you had cut off (and likely shattered) the crystal that was within this can, the gold springs that attached the crystal are still there albeit shortened (Look to bottom right of the capacitor within).
The IC essentially ranges from a simple inverter to a full featured PLL driven by the now missing crystal.
Thanks a lot, I would love to see more conceptual videos in the digital electronics field :)
This is very informative and helpful for students and curious individuals.
Glad you think so!
Always wanted to do such a practical. Thanks for the video.
Glad it was helpful!
Thanks from Texas Scott.
Wao respect to your wisdom, thanks for sharing it!
Like how you show details, thx and nice video!
Brave man, experimenting with them bricks, got my cement ones somewhere...
My brother use to have a clear purple gameboy just like that. I also have a game boy and this sounds like a fun thing to do.
When I was a kid, I opened up my Gameboy and took out the speaker. I extended the wires to lay outside the case, then hooked them up to the 6" subwoofer from my sister's car. It would have needed an amp to play at full volume, but it was already noticeably louder than the original speaker.
Pretty interesting indeed, dude! 😃
The curious thing is that I was talking with some friends about crystal oscillators just a couple of days ago! 😂
Happy holidays! And stay safe and creative there! 🖖😊
Well I sure learn something new today! Thanks for sharing and cheers!!!
i designed a pcb with an LTC1799 myself for overclocking my gameboy, was really fun and grinding is way faster now :D
Love your videos! very educational, I'm looking into making my own DAC for my Raspberry Pi.. was looking at your Amp video..
That hand-sketched intro reminds me of A-ha's Take on Me music video. Very cool.
Great video! It'd be neat to see the reasons for these frequency limits, and why it glitches when taken too far
Thanks :-)
It will glitch because the rising/falling times for signals will become too long for each clock cycle, meaning data from 2 different clock cycles kinda gets mashed together, corrupting it and causing the system to execute 'random' instructions or no functions at all as a trigger level is never reached.
In the gameboy color, the main clock is divided, likely this divider cannot keep up, if you were to bypass it you could probably get a higher clock. The next issue is the ROM in the game cartridge, it is far too slow for any higher clocks. So for getting your gameboy color to 30-40Mhz you'd need a faster ROM or even SRAM etc.
@@someguy4915 sram timing will not be able to keep up at some point also I suspect the screen might not be happy with the fast timing, idk if it has internal buffer like modern lcds
@@victornpb I suspect that the battery life will also be disappointingly short.
This was an excellent video!
Very useful videos man.. Thanks A lot !
you keep doing more and more fun experiences. I love it. This video and wireless power video.
Thanks :-)
Thank you for this video and for the work you do :)
Informing as always.
With Arduino overclocking, you can reconfigure the Atmga328p chip for an external square wave clock on by changing its fuse bits, the datasheet says the limit is 0MHz
Very helpful video. I liked it
You always struck me as a Pokemon blue kind of guy!
Great video!
Haha true ;-)
it's interesting to see the hardware being able to replicate the emulator, it's fun to be able to use x2 or x3 speed on the emulator but it's even more interesting that i'm capable of doing it on the actual gameboy it self.
Atomic Purple GBC! That was my first Game Boy too, I still pick it up and give it a whirl sometimes.
U can also get 100khz pwm from arduino normally by playing around with the timer registers for a bit
But u will only get about 160 resolution duty cycle, which in my book is still plenty to work on
Like I said. I wanted 8 bit resolution
You should take a look at the ATtiny25/45/85 Microcontroller. They come with PLL (Phase-Locked-Loop) that can multiply the internal clock source to 32 or 64MHz. You can use that to directly clock the Microcontroller (will work up to 20MHz and COULD go even higher than that) or use it as Clock Source for Timer1. You keep the 8bit resolution and have 64 MHz you could then prescale down as needed. Those Tinys come as a DIP-8 package, perfect for small projects. All you need is a 10k resistor between Reset and Vcc and a small capacitor between Reset and Gnd if stuff gets noisy. Ah, and an ISP-Programmer or a spare Arduino (my USBASP is basically a ATmega328p).
I loved the new intro!
Really like the new intro!
You truly are Great. Mr Great Scott.
Thanks ;-)
This guy teaches us very easily
Haha, enjoyed your video, super; Thanks for sharing!
After study electrical for 11 month and gets bad grab , finally i can fully understand every point of your video 🤩🤩🤩
i haven't seen a Video from you in a long time
btw. i like you new Intro
as always great content
Great video! Would be nice to see more retro game mod videos.
You don't need to overclock an arduino to change the PWM frequency. You can change some bits in the timer registers (TCCRx, OCRx, TIFR, etc) and get any frequency (under the clock's frequency) you might want. Both for phase-correct PWM and fast PWM.
AVR ATMega32A, for example, from my experience, works very well between 1MHz and 20MHz
You can create a higher frequency with the atmega by creating the duty cycle using the timers only.
the new intro is great!
Great video I never understood how over locking went about. Ps I miss the old intro you should do a vote on it.
Oooohhhh. Love the new intro!
Like the new look.
Love the new intro
Great video!
Love the new Intro my guy
Thanks mate :-)
Bro can you do a vid on digital electronics topics. Love your vids over the years, really appreciate it.
This video is amazing as all videos.Please do video on diy closed loop voice coil actuator...
I remember overclocking my old school TI-99/4a back in the day. unfortunately, all of the I/O was clock based, so any time I had to read/write programs, use the serial/parallel port, or do any other I/O I had to switch back.
Speedrunners hate him!! How this man manages to beat every GB world record with one simple oscilator!
This video well explains why everyone needs an oscilloscope
I kind of want to see a gameboy with added clock speed dial on the side
i Liked the video and Appreciate the effort you put into into :) thank you so much
nice new intro and very good info.
Thanks for the content.
Keep up the good work.
BS'D
Very interesting. Succinct. Graspable. Thank you!!
Glad it was helpful!
I came here to see GreatScott’s new look
the only mad man to overclock a gameboy
Quite impressive !
