Raspberry Pi CM4 (delidding or scalping)

I scalped the Raspberry Pi CM4 and reached 2.5GHz
Of course, it's not safe; you definitely lose your warranty and can damage the device.
I used Compute Blade RC2 of my own design. CM4 Power 5.1V up to ~4.5A
It was necessary to keep the temperature no higher than ~6 degrees Celsius. Compressed air was used for cooling.

For overclocking in

over_voltage=15
arm_freq_min=100
arm_freq=2500
gpu_freq=800

This gave me PTSD from that knife. I've had one too many slip and slice.

Don't you dare trick the algorithm into thinking this is what "raspberry pi scalping" means

Remember chillins,
Always cut towards your fingers!

I am surprised that it took somewhat little effort and didn't take the rest of the processor with the lid.

I searched yt for 'what is the reason behind raspberry pi shortage'

No wonder this video popped up

[snowdaysrule]

Oh wow is that a threadripper 3990X underneath?

Now over-clock to 7Ghz withdirct die Liquid Nitrogen😂

[kylersmith]

No way. Ive been wanting to see this for years. Thank you

[danieljuno]

That thumbnail made me flinch but you were so careful😂

[BeetleBuns]

dude's never heard of mounting your workpiece to the work surface... gives you an extra hand AND more control! Unheard of! Unprecedented! Wow!

[jierenzheng]

Time for liquid nitrogen overclocking!

As a person that just got a new Raspberry Pi 4, *THIS IS SO FU**ING PAINFUL*

[OfficialSonOfRock]

Who else was nervous thinking the knife would slip?

[HenAndPenn]

This is when you need a nail biting emoji

[g.o.a.t]

Beautiful! I'd personally prefer with out the lid

[MrPDawes]

Good way to slice your thumb open. Put edge of board on desk mat and cut down with rocking motion to provide best control and force multiplier.

I think he is being pressured by Darth Vader

@uptimelab7762 how much was the difference (temp) between stock and mod?

[adawg]

You should be wearing A4 ANSI cut resist glove when doing stuff like this with a box cutter razor knife. Its only 20 bucks for a pair and can save you from having to bandage a really deep cut

[catalystguitarguy]

Looks like a good test for Liquid Metal. How low can the temps get with insane efficiency of thermal transfer?
