PGA370 Socket Install OG XBOX Holy Grail of XBOX Mods?

In todays episode we install a socket 370 PGA370 and the Intel PIII 1.4Ghz 512K 133MHz processor Tualatin onto the original XBOX console. We'll be achieving the socket 370 attachment with the use of the open source interposer.

We'll be showing comparisons and footage of the 733MHz stock XBOX CPU vs the 1GHz and 1.4GHz CPUs that are in our upgraded machines. Game footage shown: Half-Life 2, Doom 3, Matrix Path of Neo, Surreal64 CE F-zero X, and KI2 arcade.

We know there will be an improvement, but do all of the games benefit from the CPU upgrade? Which games have the most glaring differences between the three CPUs?

Check out our previous CPU video where we install an Intel Slot 1 1GHz CPU onto the Original XBOX:

Interposer used:

Need some capacitors for your OG XBOX repair needs?

Supplies and tools we use:

CPU Upgrade, XBOX, 1Ghz, 733Mhz, Faster, BGA Rework, BGA machine, Reball, Stellar

Somehow it feels wrong to see Half-Life 2 running smoothly on the XBox.

Awesome upgrade.

8:39 watching the solder wick up the socket legs was incredible.

Digital Foundry brought me here. Great content and video!

You have a very 90s style of narration to your videos. Double-dose of nostalgia, thank you!

Bro is going to put a Ryzen 9 one day in that xbox

[BKModder]

Finally, always wondered why I never saw anyone using one if the interposer designs to not just upgrade the CPU but to install a socket for future easy swaps.

Really appreciate you performing this mod and documenting the process as nicely as you did!

The solder flowing up the pins was so satisfying lol

[plume...]

Half-Life 2 was completely transformed! Also, seems The Matrix is GPU bound. Great video, thanks!

[AlexCatV]

Thanks for the outstanding work, masterpiece)

Especially glad to see a difference between 733/1000/1400, looks amazing

[Mareka]

Very nice, I like. It makes me happy that you guys are finally showing some game play clips at the end of the install.

Any successful CPU interposer Xbox mod deserves a sub. Good stuff

[rezqiano]

That smug face after telling us that the balls has been cleaned tho.... 🤣

[cromulence]

Insane. I really hope that the 256MB RAM mod can be made stable at 200MHz, or hopefully even higher. Both of these mods would open up so much on this machine. I’d imagine that whilst it’s not easy, it’d be totally possible to modify games and/or the OS to correctly utilise the extra RAM for the GPU - I imagine being able to play more games in 720p thanks to additional VRAM!

Legitimately one of the coolest videos I have seen on YT.

[hugosimoes]

Cool! As long the CPU is properly cooled, it will never melt anything.

[shaneobrien]

Talk about an OG Xbox pro, that Tualitin chip is a game changer. Nice work, I personally hate soldering those capacitors my hands are not as steady as they once were.

[Johnny_LuvBuckets]

Thank you kekule and frank for making these interposers and making this mod easier for more people to do it.

[hosie]

Man, that's awesome. The possibilities just went higher on that thing 😁 I can't wait to see what developers come up with now that it can support a higher processor and ram

[SparkMojo]

Would love to see a collab with Digital Foundry if you can ship a modded Xbox to them!
