PS3 Frankenstein PHAT PS3: CECHA with 40nm RSX

I would recommend installing Evilnat 4.87 or Rebug with a webman. Like I said, embedded fan settings in 4.88 are unnecessary at best, problematic at worst.
 
@DeadEnd @RIP-Felix
Do we have to remove R2054 and move R2153 or not? I'm reading conflicting information.

From what I've gathered:
* 10kohm mod is necessary for COK-001/002
* leave R2001/R2002 as is on COK-001
* on COK-002 add 47k resistor to R2002
* Voltage mod is recommended on COK001/COK002 for 40nm RSX chips
* Use Rebug 4.86 or Evilnat 4.87 instead of Evilnat 4.88

Other way around. On COK-001 you dont have to do anything. R2001/2 can stay. COK-002 don't have them populated. So you have to add one according to the official documentation (47k, R2002 that needed populated. Check @DeadEnds video tutorial. I think it's correct method).

Yes, voltage mod needed for 40nm RSX. So it'll last longer.

Thank you. The video guide looks great.
And what about this part - is this still valid for COK-001/COK-002?

Edit: So the comment below his youtube video is wrong?

Sorry, I didn't mean that you dont have to do anything to COK-001. You still have to move R2153 (10k) to R2054 (replace it and place diagonally to GND). That is needed for all models this mod can be used on.
 
Can someone test the resistance of R2002 in circuit on COK-002?
When the resistor itself is measured it shows ~ 47k ohms but in circuit it's 100 ohms on COK-002. What's the explanation for this? Can someone confirm these readings?
 
It is kind of selection for ram type used by rsx. If is installed let it there if not let it empty.
Factory knows what is for. If you do modchip it can work in both cases but not necessarily to be installed.
 
COK-002 w/ 40nm - SUCCESS

Thanks to Ed from proconsoles.nl for doing this installation!

I provided him with a total of 2 consoles and 5 orbis chips. 1 COK-001, 1 COK-002 and 2 KTE-001 mainboards.

Here's a few pictures documenting his work.

I'm having a hard time following this thread because I don't know electronics on this kind of level but this would theoretically help CECHA/B users with keeping these consoles running long into the future? I have a CECHB model that has never YLOD'd but i'm concerned that it's just a ticking time bomb, even with webman mod fan mods keeping it at a reasonable 63 degrees Celcius during game play.
 
@ad-min nice, enjoy this bad boy. also the 47k resistor is a gamble it can work with or without, but have it installed wont hurt anything. what i dont see in the pictures and is concerning is the voltage regulator mod. without it the life of the rsx will reduce. @complexusername it propably has strong solder points. its not the first launch console that still working. a delit and repaste will help further

I think you mixed it up. You don't do anything on a cok-002. But you must remove R2001 on a cok-001 . R2002 could be in theory replaced with a 47k, but didn't you say it won't matter what value it is, as long as R2001 is removed (It's a voltage divider, you said so yourself).

Edit: Yes you are correct. It's a voltage divider, so the value isn't important. It just pulls High, low, or sets a voltage in between based on the ratio of values chosen.

EDIT: Here is what he said exactly.

...R2001 and R2002 removed, put 47k in place of R2002, this was done specifically for cok-001. to avoid GLOD problems on console

...there was a GLOD for some of the cok-001 that we installed, at that time we used cxd2991 and cxd530x, I forget the exact cause of the GLOD happening in cxd2991 or cxd530x or both can happen, which is clear with a solution changing 47k can eliminate GLOD, so we apply until now.
the memory is blurry now because we did it maybe 5 years ago...

nb: strangely for the type cok-002 we never had a GLOD problem (installation of cxd2991/cxd530x), if you pay attention to R2001 and R2002 there are no resistors, as if they were left open, I will find out later, there is a difference in resistors (R2001&R2002) on the cok-001 and cok-002
Click to expand...

Okay, so what I said before wasn't quite right. The GLOD issue never appeared on COK-002 consoles. But they started adding 47K to R2002 just in case, I guess? It was COK-001 consoles that sometimes had a GLOD that was fixed by removing R2001.

Is it a ticking time bomb?

Well...yes, but not so much that we should go hacking up working consoles to fix what ain't broke yet.

Having said that, I still have my original PS3 I bought back in 2012 ish (A model). It was refurbished by gamestop. I never questioned it would work until finding out about the YLOD. Then I set out to prevent it by using better thermal paste, delidding, fan mods, case mods, etc... I went so hard that I ended up doing more harm than good. For example, cutting a hole in the case over the fan helps get lower CPU/GPU temps, but causes the PSU to overheat. I designed a fan shroud that sits in the card reader slot so I could attach a 40mm Noctua fan to cool the PSU in that console. This need to fix what ain't broke is a psychological Hack, an insecurity that makes us malcontent whenever we learn of an imperfection. It could be almost anything, like crows feet or bags under our eyes. A big part of marketing is creating a problem to solve by exploiting this psycho hack. Basically, don't overthink it.
...this is advice I struggle taking. So I may come off hypocritical.

I'm aware of this fault in myself and choose to move forward regardless. I'd rather trip over myself overthinking things, than give up. I'm okay with being wrong. I'm here to learn.

If the console is working, all you need to worry about is regular maintenance. Custom fan curves, clean out dust, repaste every few years or when temps start climbing. You don't need to do any other preventative maintenance. Enjoy it while it lasts.

This mod just give skilled technicians a feasible method to fix these backwards compatible early model consoles. It wouldn't be worth attempting such a difficult install on other models.

In a way, it's true. If the console works , perhaps there is no need to go above & beyond to rip out your og RSX for the preventative maintenance sake. However, some of us believe the stock gpu is inherently flawed. It was manufactured at the time when Nvidia struggled to get the packaging formula right. I doubt Sony was immune to the problem. There were reports of bumpgate, inter-layer delamination and underfill issues. It took them a while to perfect the process, but by the time 40nm rolled around the packaging technology had improved. But this is just my own conclusions, everyone is free to think otherwise. Having said that, there are examples of untouched systems working for a decent amount of years as well. So not all 90nm are equally terrible, but noticeably many seem to die sooner rather than later.

Here is some food for thought.
