PS3 Frankenstein PHAT PS3: CECHA with 40nm RSX

@DeadEnd after i change my monitor i have trouble run psx and ps2 games it solved with video settings reset. Also do you remember broken sword? When upscaling is on it will give black screen when its off it is playing ok. there are other games that can do that. Its a flaw on cok-001 Board. there are forums that said about that before frankenstein even become a known repair. Ofcource if i knew about cecha bad habits and repair dificulty i would chose a cechc or ceche

so after what setting i should change after video reset ? should i reduce it to 720p or less ?
i try using AV cable instead and still doesnt work my ps3 using ofw even i try using cfw in ps2 emu Software mode the game doesnt run idk why..

You actually ran broken sword by disabling upscaling? I've never heard of this before... Ha. Well it's great to know.

I'd say it's a conceptual render, it just looks to good to be functional lol, also the seemingly matte finish of the die is either a resin covered die or just a conceptual render made to look good, and I don't think they're gonna cover the die with resin so probably just a cool concept. We'll have to wait and see

It doesnt looks exactly like the render, a bit dissapointing because that render was an official image :/
Anyway, i been calculating his size roughtly (by comparing it with the M.2 connector of the steam deck) and the APU seems to be around 2cm*2cm. Now im wondering how many BGA pads it have below, the diameter of the balls and the pitch in between them, lol (hysterical laught)
It seems they have glued it with epoxy at the corners, maybe to increase the structural resistance a bit, it doesnt have a metal stiffen or anyting surrounding it but is because the silicon is almost as big as the substrate

Is awesome how they was able to pack all this x86 power at that size, i have to admit i thought it was going to be a lot more bigger

hi guys
got my self ps3 fat with rsx swapped by @botakompong itself but seems like the ps2 EE chip is broken ? i just get black screen when playing every ps2 game but ps2 menu works (hold ps button on controller ) it just black screen even though im swap back to ofw

btw if anyone gonna need orbis chip or cheap rsx from botakompong it self pm me i help you guys out

That's sounds like the same issue I'm having with my ORBIS modded frankenstein. Goes to black screen when loading any PS2 game, but XMB menu is still able to come up and exit back to PS3 menu. PS1 and PS3 games work fine.

I shelved the unit to eventually circle back and never did. I thought it was a one off thing, since others have installed the orbis mod and it worked. Albeit on COK-002 consoles. Mine is COK-001 (A model). I thought it might be an issue on this MB, but @botakompong said he confirmed PS2 BC does work on COK-001 MB revisions. But here's another one...

I don't like what that might mean.

He was talking about boards with syscon 201GB having ps2 issues. But I know another person who has installed a 65nm chip on a board like that and there are no issues with ps2 games... Not sure 65nm is playing a role in this.

There was some later disscussion about that, but I read his post to mean another orbis mod on a COK-001 was having this same PS2 black screen issue I am.

This is actually what motivated me to dig deep. All the research I've been doing was an attempt to understand what's going on with this issue. It acts like it's being held in reset. Which is what had me suspicious of the changes made to CGreset. The SB controls the PS2 reset pulse and is supposed to coordinate the start of the EE+GS when the CPU hands over control. I wonder if the orbis mod interferes with this sensing operation, since it has to tap into the RSX power on reset sequence.

I abandoned the idea when @botakompong confirmed it did indeed work on a COK-001 he had. Although he did say he doesn't get many in.

So I've been looking at schematics and tracing voltage trees to get to a point where I can troubleshoot every signal and voltage on the MB. Which was a long discovery process. I think I'm at a point where I can finally attempt to troubleshoot it. But I think I'm going to have to reverse engineer the orbis mod's SPI interrupts to put these CGreset suspicions to bed.
 
Yeah, I'm curious to find out if it's just some kind of bridge chip failure, voltage line for PS2, etc. I finally finished that voltage tree and testpoint project. So now I just need to get the boar on the test bench and start measuring everything!

It'll be a learning process for me, since IDK when the PS2 voltages are supposed to show up. I'll need a working MB to compare with. So that means I have to do it twice...ugg! Troubleshooting is tedius!
 
Also have a CECHA with PS2 issues, no PS2 logo, but the menu opens and I can exit to the XMB, it still have a 90nm RSX, but I replaced both RSX and Cell tokins, before the change already had the problem, hope to find a solution.
 
So that makes 4. Sounds like an unrelated issue then. Black screen of Death.

I wonder if the SB UART would reveal anything useful? Or if the PS2 bridge chip has any logging function.
 
Guys maybe you can try to launch ps2 games on these units when temperature is around 75? I know it's sounds strange, but last cecha unit I had was unmodded and it had same issue. PS2 games were working only on temps above 75, it had either freezing issues or black screen (basically it freezes on black screen during ps2 logo boot sequence, hence you see black screen)

Might be capacitor issue? I doubt it's related to ee+gs

I did tried that, and this PS3 was running +80ºC, but no success.

Also doubt it's EE+GS issue, more like a shorted capacitor or some other bad component, it looks like it's just not starting, I did a test mounting a disc with wMM and after starting the game no led activity from the HDD.
