I don't even understand how people managed to put a freaking mod chip in a PS3 to begin with LOL.
Yeah, that's a good point. A models are COK-001 revision motherboard and this one is COK-002. There are 2 capacitors that are populated on a COK-001 that are not on a COK-002. If we see it put back on for this COK-002, then it confirms the need for it. If it's a mod chip, then we can confirm the wiring. If it's a refirb, then we can confirm the HW changes needed on a COK-002, which we haven't seen before. That's good news for you UK guys!
After contacting the seller I bought it off I can confirm that this ps3 was sent off to Sony for repair in its life which is probably why its got a different rsx chip. With syscon fan settings stay at 25% fan speed as the cell is at about 70 degrees and rsx is about 68 to 75 degrees but never hits 80 like my old 90nm fat model.
OK I will tear down the Ps3 again and take loads of pictures of the motherboard on the front and back I will upload a folder on my Google drive with all the images will post back when I have done.@tristen8878 Firstly, great find!!! Second, please don't disappear!
As others have noted, yes we have seen a VERY few number of SONY refurbished consoles in the wild with 40nm RSX chips. They have special firmware that enables the RSX and there are a few hardware changes to the motherboard itself (just a couple of small resistors under the RSX that are slightly moved. However, we haven't been able to get very clear pictures from the original owners of the console to confirm these are the only changes.) So we desperately need some good pictures of the bottom side of your board!!! Could you please take a bunch of pics and upload to the forum? You should be able to just drop them into to reply box to attach them.
Without the special firmware, you can't just swap for a 65nm or 40nm RSX. However, there is a mod chip that claims to allow it, but we are investigating that at the moment. If there is a mod chip like the one we've been testing out in the Frankenstein PHAT PS3: CECHA with 40nm RSX thread, then it'll be on the bottom side of the board. So pretty pretty please, can we trouble you for some photos of the backside of the board?
If it's a mod chip, then we are looking for something like this:
If it's a SONY refurbished unit then we're looking for in focus hi-resolution photos of the entire motherboard, so we can confirm the hardware changes. Also, we need the firmware dump. @M4j0r knows how to dump the firmware and what else we might need to hopefully replicate the mod.
@tristen8878 The end goal is to make every BC model as reliable as a slim model. SONY isn't talking, so we have to reverse engineer it. You are holding the key! Sorry, but the weight of history rests on your shoulders. You have been drafted into the service of retro preservation. Don't let us down, son...lol!
Here's the changes made to that board @Sampsonay. They are consistent with SONY's 40nm refurbished board we've seen already, but more pics are always needed to hopefully spot any other changes. I wish this was higher resolution though. Oh well.
That'll be great. Could you also post a picture of the following...
[Settings] > [System] > [System Information]
for a few seconds
and keep it held, press once to have the menu stay up on it's own.Before you go any further would you be able to tell us what it says for the syscon in the more system information screen?
A bit late but it did :P
Is not only related with RSX replacements, but with the research about finding syscon exploits (that could affect all PS3 models), as an important part of that research is needed to complete the collection of syscon firmwares, and your PS3 seems to be the only one missing
To be clear... it should display 0F29.0001000500000002 @ SCTake a picture of that screen and upload. This shows the firmware revision and some useful breadcrumbs that could help us out.
- Go to XMB
[Settings] > [System] > [System Information]
- Press simultaneously
- Release those buttons then immediately press
- While holding
A bit late but it did :P
@tristen8878 to get an idea at how important is this take a look at this post written by @m4jor he has been involved in the last published syscon hacks so he knows very well what he is talking about

The first thing we would like to see is the info displayed in this screen mentioned by @RIP-Felix
To be clear... it should display 0F29.0001000500000002 @ SC
Check this post reported by @DoublesAdvocate, it was the frankenstein v2 (with a 40nm RSX), and your PS3 probably is the frankenstein v1

Thanks man, but they need also that button combo on "System information", there's important data they need to compare.
