TL;DR:
I put a 90nm RSX into a CECH-2003 Slim - DYN-001 motherboard.
It obviously works ... but don't do this
Alright, sharing a mildly cursed mad scientist experiment I finally decided to document share this one.
The "crazyness"
Reverse-Frankie: installing a 90nm RSX into a Slim (CECH-2003, DYN-001 board).
Yes — the exact opposite of what I/we normally try to achieve in putting a 65nm or even better a 40nm to replace a 90nm
Why though?
Disclaimer (important one)
Bonus chaos factor
The board itself (DYN-001) is full of oxidation.
Honestly, I had very low expectations:
Result
Reality check
Let's be honest:
If anyone else has done similar "reverse" nonsense for fun, I'd love to hear how long yours survived.
And yes, you're absolutely allowed to say this is a terrible idea —
I'm just ahead of you :-D
I forgotten to add that indeed that BD drive is not one from a 20xx model but from a CECH-L03 (if you ever wondered if it works, yeah it works fine).

- Because I can :-D :-D :-D
- I've got a stack of Slim boards (20xx / 21xx / 25xx) where the original 40nm RSX has already been "relocated" into proper Frankie builds on COK-00x boards
- I'm waiting on more 40nm chips to finish a queue of boards to do … and patience is not my strong suit, I was bored
- This is not my first time doing it, just the first time I thought "fine, I'll post it"
Disclaimer (important one)
- This is NOT a recommendation
- This is NOT a proper project
- This is basically: "I had parts, tools, and poor decision-making alignment"
- I'm not selling this, not even reassembling it nicely
- Longevity expectations = somewhere between "meh" and "don't ask" or even "don't care"
Bonus chaos factor
The board itself (DYN-001) is full of oxidation.
Honestly, I had very low expectations:
- Board: questionable
- RSX choice: questionable (nah, lets be honest, mad stuff - AGAIN!)
- Outcome: … working
Result
- It boots
- It runs
- It behaves… normally
Reality check
Let's be honest:
- Thermals → not bad
- Reliability → not ideal
