PS3 Frankenstein PHAT PS3: CECHA with 40nm RSX

DoublesAdvocate said:
Okay so I found someone selling a CECHA that was serviced (mobo replaced) on the 11th of June 2010, as far as I'm aware this would have been before 3.41 release meaning it's impossible for it to have the 40nm RSX have I got all that correct @M4j0r ? Is it possible that this unit would have the 65nm RSX instead?

It's possible, but the syscon which supports the 40nm RSX is dated 2010, while the older one (which hasn't been found yet) is dated 2009.

Right, but the first update that has the 0F38 syscon revision is 3.41 which released after the 11th of June 2010 so it would be impossible no? 0F29 would also be impossible since it only began to appear in 3.40 which also released after.
Am I understanding this correctly?

Okay, thank you for the clarification. Is there any other way I can find hints for a timeline on these units? Anything before the release of the CECH-2100 in March 2010 should be impossible to have a 40nm RSX correct?

The FCC got the CECH-21XX already on December 7, 2009 (from production at Foxconn) so it's safe to say that Sony already had the 40nm RSX in 2009. It was officially released in March 2010 though.

At this point, if I didn't miss any hardware changes and my EEPROM dump looks correctly fixed, this has gone above my pay grade. I also have no use for this board now. It's gone through 4 rework cycles now, so I'm not gonna put it through 2 more to try to swap a working GPU and syscon back on it.

So, do you (or anyone here that's capable) have any interest in getting your hands on this board and continuing to work on the problem? I'll even cover the shipping cost.

Hi, I have interest, if you want to send it over. I have taken a break from the experiments because of studies, but I will definitely get back to it when I can.
 
I got some news who ever wanted do put rsx 53xxx into what ever ps3 fat with some weird chip mod called ic cangkok rsx it claim that can let u swap ur rsx from superslim into fat you can youtube it but the video not in english

Interesting, but was he Brazilian, Portuguese, or Indian? Can someone decipher what he is saying. It looked like he did cgreset on the one solder but what is that custom pcb he installs in the beginning doing? Maybe there is an extra chip we are missing here. Does he reprogram syscon? Does it even work? More questions than answers. @squeept , thoughts?

The custom pcb he install are the chip mod to let u to swap the rsx and he dont need reprogram etc just put the mod swap the rsx and some regulator from slim
If u buy the chip they gonna sent u instruction how to do it
Seems like people in my country already have they ps3 fat swaped rsx with that so its works
I dont have work ps3 fat to test or sent to store to do swap so idk how it works
Its indonesian btw
 
I really feel it's a scam. I don't see how he is getting around a ton of things. Super slim rsx I believe has a different footprint from original ones for starters. It would ylod on first boot from syscon not being touched. I'm sure there are probably a bunch of other things to. Need some of the people who have been working on this to chime in. Reach out to that guy in the vid and see if you can get him to come here and answer some of our questions

Wish that i could invite the guy in vids but he seems non english speaker so i try talk to him in whatsapp and ask him to sent me the instruction and upload it here
And he doesnt giving it the only turtorial he have are that youtube vids so i reach the mod chip seller it self and ask them if they gonna giving instruction too do it if i buy the mod chip hope it getting good answer

Can you try to buy that IC chip from his website?

Here he was selling some type of a manual book for different boards with pictures.

I've tried googling the chip datasheet based on this picture, but nothing comes up.

Here is another link, I doubt it's a scam tbh, Hopefully someone can find a shop that will ship outside Indonesia.

It aint scam cuz im already to talk to every people in ps3 local fb group
I can ship it to outside of indo but i need schematic or instructions from them seems it like "company secret " thing and all seller just selling mod without instruction
The only way seems have fat and try ask one of those service store to swap the rsx and do analysis of it
 
You can see here that the modchip actually connects to the SC <-> RSX SPI connection (MISO and MOSI) if you compare it to the service manual: https://s2.bukalapak.com/img/785144893/large/2016_09_07T13_09_06_07_00.jpg .
The other two connections are GND and VDD.
Seems like it's based on a Xilinx FPGA.

So why did Sony not just use a "mod"chip? They used this method in the past (PS1, PS2, PSP) for small batches.
