PS3 Frankenstein PHAT PS3: CECHA with 40nm RSX

Hi.I moved it from the COK-002 board to the COK-001 board,CPU.NAND.SYSCON. But there is no launch Error : BitTraining SB:RRAC:BX0:BX:FLEXIO_ID ERROR 4003.I understand syscon is not compatible with COK-002, on COK-001?Maybe there is a team?to make it work on COK-001.And what does SB mean?

Hello, welcome here. It is interesting that you talk about this.

SB refers to southbridge, and in your case you are getting failed bittraining, failed SB:FLEXIO_ID with 4003 error code.
Bittraining is a process that occurs between the CPU and RSX, and between the CPU and SB. The communication between them is checked to make sure everything is OK before booting.
The CPU plays the central role in this and the SYSCON is calibrating and supervising everything.
Could we get more details like the full errorlog and bootup sequence?

My interpretation of this is that the old bigger southbridge found in COK-001 boards is not being compatible with the newer CELL CPU and SYSCON from COK-002. Assuming your work was all good.
Wether this could be just a matter of software or not... I dont know (like our magic training patches for the SYSCON that solve the RSX:FLEXIO_ID issue)

Maybe other people here tried the same
(transplant CPU from COK-002 into COK-001)
and have more useful knowledge than me.

Cheers
 
I had a CECHA01 in this week that was warranty sealed and appeared to have a genuine Sony RSX replacement, but it was a new 90nm that was throwing A0403034. I skipped straight to Frankenstein despite the chip ohms looking good because it already had rework cycles on it. This lead me to two things:

1.) This Sony repair when replacing a 90nm with another 90nm still removed R2153. There were no other apparent changes and I still had to fiddle with the rest of the resistors.

2.) This is now two consoles in a row where I did a COK-001 with a Super Slim non-IHS 40nm (this time was CXD5302A1GB) that used EC instead of EB in the syscon. I think that's all but verified and needs updated. @RIP-Felix I still use your signature for a quick reference on anything I don't have printed out in my personal service manual, so you may want to update that.

Unfortunately I don't have a thermal cam, I go by the syscon readings when testing them after installing the 40nm

Ok and has there been any other affect to the RSX chip itself such as warping during the BGA rework or anything else visually that you can see that shows a negative effect because of the rework itself?

Nope, i've done quite a few, even one today with no issues, so i'm pretty sure it was just a bad chip from a dead console (that's where it came from).
 
CELL has "stabilizing?" resistors on each corner of bga. Why some consoles have on RSX and some on RSX don't? How important they are.
 
Cok002 is last mobo without spacers on rsx corners, think sslims won't have as ic area and mobo isnt that big and flexible. Just use those tiny caps on corners of rsx if you do 40nm swap "Frankie". You will thank me later @mimi. Just do it don't overthink.
I'm not speaking to well English to start with full story.

I checked slim, it does have. I wish i could, i only send my console to technician :\. CELL cpu on cok-001 does have them. :)
 
Anyone have healthy measurements for cok-001 with 40nm RSX chip?
my cok-001, 40nm (cxd5300a1gb):
RSX_VDDC - 4.4 ohms
RSX_PLL - 15.50 kohms
FBVDDQ - 264 ohms
RSX _VDDIO - 96 ohms
VDDA - 4 ohms
MC2_VDDIO - 1908 ohms
YC_RC - 8.8 ohms
 
Hi everyone! I'm new here and have been working towards swapping my PS3 super slim 40 nm RSX in a frankenstein build but I encountered 2 things that concerned me.

1: My 40 NM RSX for the super slim appears to be slightly different from that of a normal slim model and the actually GPU that's in the center of the RSX chip is slightly lower than the chips around it. I'm wondering if this would prevent good contact with the heat sink and cause overheating.

2: I also was wondering if my super slim RSX 40 nm is different to a normal slim 40 nm in how the mod is meant to be done or if the process is identical for every 40 NM slim or super slim alike.

please and thank you for any answers you guys can provide. I'm a bit new to this community

You have super slim that has 28nm RSX, that is incompatible with this mod.

Wouldn't be easier if from the beginning you upload photos from your mysterious RSX?

here you go
 
Anyways. Besides the question I already asked is there anything I should know about doing this mod with a super slim vs a normal slim that may make it different than usual or would it be identical?
