Ahhh yes, i forgot about the VRMs, my appolagies, as long as it provides the same voltage as a 90nm one, i dont see the problem people swapping out to a 40nm, besides the 40nm ones are bulletproof compared to the 90nm, and with that massive 60GB Cooler, i presume temps will be on the 50ºs threshold or below, since is what a 40nm from a 2104 did run for me with a delid,and thats underload.
Shame the CELL is paired with the syscon, if it wasnt, that would guarantee another swap, would make the ultimate backwards compatible.
I wonder if the fact we have all the syscon keys for the COK001 motherboards would allow us to pair another CELL now somehow, that would be interesting.
The overclocking potential of newer chips with bigger older coolers could be interesting too.

Is the kind of thing that should be tryed by someone that works in a repair service and have a bunch of PS3 motherboards stacked in a pile as "damaged"
I hope someone does it to solve the mistery if that resistor grounding the pin CGRESET is the only thing needed for this hack to work

Overclocking on a console, i am not much interested in it, i do it mostly on a PC due to much better maintenance and cooling than a console, i see no benefits on a console for a huge heat exchange for a fraction of the framerate, anyway, but I am really interested in this topic, see where it goes, and hopefully in the near future once all has been figured it out, we can swap the old 90nm fabric for a more cooling 45/40nm with both CELL and RSX, on the 60Gb making this a more reliable source of new chips, and easier to obtain.I wonder if the fact we have all the syscon keys for the COK001 motherboards would allow us to pair another CELL now somehow, that would be interesting.

Well many are interested in it, and no one has ever overclocked a 40nm with CECHA heatsink and fan control so how "huge" the extra heat to extra framerate ratio would be is yet to be determined IMO.

Overclocking consoles is bullshit . especialy ps3. with its underperforming cooling. no interested in that. but changing my not working rsxin my cechc would be awesome.
You might not be. But plenty are interested in reinstating the clock speeds used in pre retail OFW. Sony reduced the clock and mem speeds approx 10% before release probably along with that they reduced the fan speed.
you do not have to be interested, I was not trying to tell anyone what they should do? My point is that the 40nm rsx runs way cooler and needs less power, So in conjunction with the bigger heatsink from fat we might be able to get that speed back by overclocking it without any downside. It would probably help in some games like farcry

Yeah they know why.
thats sound interesting. but first we must prove that it can be done. and then how many peaple will vandalize working slims to do that?
If i could do that it would be fantastic. but in my country nobody does reball so for me it is still a wet dream.And for overclocking yeah you are right that many people will be interested. but it will not affect the speed of the game and make for some poeple this an advantage lets say for online play?
Yeah I was just speculating that it is interesting and some probably will do stuff like that. I know not many will do it, and I wouldnt do it myself.
As for vandalizing slims, hopefully not. But if late slims RSX is compatible, then there is a good chance all slim RSXs are compatible so there is e a good few available for parts.
It might be an advantage for online play.. who knows. probably would be.

Far Cry 3 and 4 are my favorites haha. Imagine a CECHA with a, let's say "custom RSX", and overclocked. Like I said, that "must be worh something else". $$$$$

That serial from the link is CXD5300AGB... but CXD5300DGB is a newer revision
Compare in the table in wiki, CECH-21xx and CECH-25xx are all them CXD5300A...

Some are AGB, A1GB or DGB, which the "5300" only changing from SUR mobos till MPX's. We know that the 5300DGB works on a COK-001, and every RSX seems to share the same traces, but not all of them are compatible with every mobo, so the key here are the last three letters. So we only have to know if AGBs and A1GBs are compatible with a CECHA. And taking in mind too that grounded resistor.

The order is something like this, is just some of the ones im going to mention doesnt exists, was never used in retail units, or never was found
CXD5300GB
CXD5300AGB
CXD5300A1GB
CXD5300BGB
CXD5300B1GB
CXD5300CGB
CXD5300C1GB
CXD5300DGB
CXD5300D1GB
The letters at the end are small variations/updates of the circuitry (so as a general rule, newer revisions are better)
The "1GB" is a variation of "GB"
After that they moved on from "5300" series to "5301" series and they started again

True, although I am not excluding it for the interested minds, i was talking mainly with a purist hardware, i honestly prefer overclocking on PCs again for they're flexibility, on Consoles i like to experience the Hardware as it should be, but i am sure LuanTales would be interested in overclocking to integrate it as part of the PS3 Pro Mod.
Ive read somewhere down the line that $ony downclocked the CELL to minimise heat exchanges and performance, and sacrificing fan speeds, didn't they overclocked the CELL, ive know that they're first PS3 Prototype CEB used a 2.4Ghz CELL back in 2004/05,before they switched to 3.2Ghz,same with the RSX got a bump from 128Mb to 256Mb, and a fee clockspeed touches, on the final SKUs, correct me if i am wrong.

I was paged? I think you all figured it out already. Looks official to me. I doubt anyone without access to some real Sony documentation on the syscon would have just known to do that. Especially since it's been pretty well documented that we couldn't swap between process sizes, so they would have been putting in a lot of work and parts testing it out on a whim that goes against what has already been documented. There was a reference chart on the BGAmods forum about confirmed GPU swaps that work, but I just looked and that place doesn't appear to exist anymore, but I remember they were all the same process size. Even then I think a few didn't work, but that could easily have been a dead chip or operator error.
Just checked the pictures again....that's almost definitely official Sony work. The IHS looks like it was glued back on with the Sony stuff. If you scrape that stuff off is it stretchy and rubbery? The plaster stuff I use is closer to latex feeling when it dries, instead of hard and a little flaky like the Sony stuff. Some people leave the IHS on when they are doing rework, but since the GPU on the Super Slim doesn't have an IHS to begin with, that was definitely added, so they had to put adhesive on it themselves. If it's exactly like the Sony stuff you're used to, it's official. There is nowhere I know of to buy exactly what they use, or I would have bought it myself.
Doesn't look like there's flux residue everywhere? Check the bottom side of the USB connectors where there is always a huge puddle of flux. That will tell you if they put it through a new cleaning afterwards. The only cleaning methods I know for the general public are fairly harsh liquid chemicals, and then they need baked to dry afterwards (for the full immersion that a BGA requires to clean under), which will leave the freshly exposed and cleaned copper around the edge of the board looking like a rainbow as it oxidizes. I can see in the sticker picture that the copper looks normal, so if it was washed, it was washed by Sony.
Not saying it's NOT official if it wasn't washed or you find the latex stuff. However, if it was EITHER washed or glued with the right stuff, then it definitely IS official.
Great find either way, I might have some boards in my scrap pile that I can bring back to life now. I'll sacrifice a Super Slim to save a CECHA01 any day.
edit: just found a super slim already missing the GPU in my scrap pile, grid is exactly the same on both chips, so I don't think there's any magic going on underneath the chip unless they cut a trace or something. I think that one little resistor is the only change.
