Overclocking a 90's Industrial Computer

Today, we're swapping the processor in the 90's industrial computer for one with MMX, and then we're going to try and overclock it!

I wonder if, in cleaning the LCD, you inadvertantly removed the front polarizer. That would give you nothing but a white screen (That is, the backlight shining through and not being blocked)

[UsagiElectric]

I love this coffee table destroying box of industry!

[maurvir]

Seriously amused that you censored the paste application. That was great!

Just a small note, most processors if not all in the socket 7 lineup were multiplier locked and could not increase the multiplier, but you could always use a lower one. The method for overclocking the p233mmx is set the fsb to 75MHz with the stock 3.5x multiplier or if the board supports it 83MHz with a 3.0 multiplier, netting you approximately a 263MHz/250MHz Pentium experience.

You could remove most of the heavy steel chassis for a fraction of weight... save just the front panel and LCD... 3D print a few fittings.

I think you may have fried something when the CF to IDE adapter shorted.

I remember noting that when you removed the IDE Cable, you moved it FROM the socket that's dead, and plugged the DOM into the one that works. If that's true, you would have never registered "shorted adapter = dead IDE" because it worked after you installed the DOM.

That's an Intel Advanced/ML (Marl) motherboard which only provides a single CPU voltage rail. You are overvolting the Pentium MMX as it is a split voltage CPU! Classic Pentiums use 3.3v whereas the MMX is 2.8V! Only a Pentium MMX Overdrive is supported as it has onboard voltage regulation.

Initially when early IDE/ATAPI CDROMs came to market the motherboards bios would not detect ATAPI/IDE CDROMs as they were not designed to work with that type of devices and would also not be able to boot from them, BUT once you load the CDROMS driver on DOS or another OS it would work.

And, for reference, the WHITE image IS NOT the motherboard, it will be the graphics adapter OR the LCD controller itself. Though from what I see I would advise you to check the cables between the LCD controller itself and the LCD panel as I have seen this before and it was due to a bad connection between the LCD controller and its flat panel. So check the board the VGA cable connects to and then check it's connections to the panel.

everything seems perfectly normal here!

“It shouldn’t be too hard”… famous last words. 😂

This is the greatest overclocking video I have ever seen. I laughed so hard when you showed the cards hanging off of their cables attached to the motherboard, I paused it to show the wife and even she started laughing at how janky the setup was. Keep them coming.

I loved the I'm freeee! popup :D. great stuff!

thanks for taking us along on your journey with this! excited to see the next installment

8:26 I love how you blurred out the thermal compound application so arm chair PC builders can't leave their expert opinion how much compound you used in the comments. BTW, you used too much. 🤣

[friedtomatoes]

Board repair is tricky and difficult. I'd recommend getting a thermal camera and looking at things that get hot. Also replace the caps

[ArniesTech]

I dont know what it is but whenever I see an old motherboard, I get all excited 😁

[westtell]

Yeah i think you accidentally removed the polarizer cleaning the LCD
