Something that I've been working after I have failed with new sockets from Aliexpress.

Still looking for ways to test rsx faster before we soldering on board.
Files attached may work in kicad. View attachment rsx3.7z
Edit
If anyone fails to open it please let me know.
As for product it will fail for first, just note that no silkscreen needed.

Our crazy talk may be getting very real hahaha
This was always the next step... Who needs boring voltage reduction mod? Make that frankie run FAST!

@vyktormvmpay25 here's the things I started getting some spam in my e-mail about recently: https://www.ironwoodelectronics.com/products/grypper/grypper-list.html
The "zero footprint" is pretty much a requirement for this application. My concerns are the relatively low life cycle (50 insertions for the model that looks correct) combined with what I'm assuming is a very high cost.

Not going for something fancy for now. In theory we could solder that adapter on motherboard then on top rsx should stand on it with a little bit of pressure. I use very specific spacers on my jig stand. If that work for me must work for everyone. Production for those spacers of 2,8mm or 3,8 mm for cell will be hard for example. I'll provide all info later if work for me.

Using victors design you could solder spring loaded pogo pins into the vias and use the board as an adapter without soldering. If only they were a standard option for a board house to assemble it. Then you could just order the PCB and have them install the pogo pins. Then the PCB would go between the MB and RSX. Both would be cleaned with only their BGA pads, no need for balls. The pogo pins make contact and maybe the heatsink provides the force to depress the springs and make contact with all the pads.

Ops, i was a little confused too, when i made the drawing i forgot KTE-001 (from PS3 model CECH-30xx) is the first motherboard using a syscon with 100 pins (squared), and i was mostly interested in syscons with 128 pins so is not exactly what i was looking for, but i added the info here, is progress anyway
https://www.psdevwiki.com/ps3/Template:Syscon_pinout_LQFP_100_pins
If someone else can check that 4 pads of the RSX SPI bus in a syscon 128 pins please advise me, at this point this detail is important, not only because was used by the orbis modchip but also to clarify a bit the mess in wiki
Thanks, i added the info here: https://www.psdevwiki.com/ps3/Template:Syscon_pinout_LQFP_128_pins
Both seems to be syscon inputs, so is RSX who "switches" the transistor, so we have this, only valid for the rectangled syscons (128 pins)
Code:
(rectangled) Syscon pin 48 <--- transistor1 <--- VIA1 (top on the photo) <--- RSX pad AR22 (signal name: VD_VINT0)
(rectangled) Syscon pin 76 <--- transistor2 <--- VIA2 (bottom on the photo) <--- RSX pad AY7 (signal name: RSX_INT)Are different syscons, but i know the location of that VIAS is common for the latest PS3 slim motherboards, so we can combine both resulting in what i menationed above
But can you check this ?, specific for the squared syscons with 100 pins
In other words... first you need to check in between the RSX pads and the transistors... and then check again in between the transistors and the syscon pins... the goal is to find the syscon pins
Code:
(squared) Syscon pin ?? <--- transistor1 <--- VIA1 (top on the photo) <--- RSX pad AR22 (signal name: VD_VINT0)
(squared) Syscon pin ?? <--- transistor2 <--- VIA2 (bottom on the photo) <--- RSX pad AY7 (signal name: RSX_INT)-------------
EDIT:
And finally... can you check if the RSX pad AL38 is connected with syscon ?... this is mostly speculation, but im asking about it because by looking at his names it seems to be "the siamese brother" of pad AR22, and i guess is the same electrical circuit (with a transistor in between RSX and syscon), the names are:
RSX pad AR22 = RSX_VINTE0 (RSX pad name), after the transistor is named VD_VINT0 (syscon pin name)
RSX pad AL38 = RSX_VINTE1 (RSX pad name), after the transistor is named VD_VINT1 (syscon pin name)
Im guessing if you found one of them the other should exist too
Most of this names and speculations are based in the service manuals from the first PS3 fat models though, there is always the possibility that sony removed this connections for PS3 slims or superslim models, but this doesnt seems to be the case, this lines are control signals, as far i understand are sending some kind of "voltage interrupt signal" to syscon to indicate that RSX is healthy

Hey friends, so i had ordered a "nos" 
40nm RSX (CXD5300) about 1 month ago from a Chinese eBay seller, after 1 week they told me they had no "new" ones left in stock and only used / refurbished ones. So i said send it anyway, well it arrived today and check this out...
They cut it out of the board!! I've never seen this before, like whaaaaa?? On the bright side, at least it hasn't endured another thermal stress by being desoldered, i guess lol
...and hey i got a few extra MLCCs for free! 
As Vic suggested, i'm now looking to buy KTE-001 and harvest the RSX from them instead.
EDIT: strangely enough, everytime i just look at this cut-out RSX i keep hearing "George Takei" saying "Oh My!" in my head lol.

No...just no. That's unaccepable!
To avoid this in the future I suggest buying CXD5301 instead. I've tried searching e-bay for 5300 and 5302. Nothing comes up. Or if it does, it's twice the price and clearly salvaged. So stick to the CXD5301's until that supplier dries up.
Better enjoy it while it lasts, cuz after they're gone it'll be a matter of salvaging from slims or taking a chance they send something like that!

Yeah agree 100%
@sandungas
AL38 -> pin 64
top via -> 10K resistor -> pin 62
bottom via -> pin 72
Not seeing any transistors in there.

Hey friends, so i had ordered a "nos"
50 bucks says those are the same as the "new" ones they ran out of, they just lost the guy that pulls and cleans them or their machines are down.
I mean, ask yourself why this seller just happens to have both of those items on hand.

Personally i think if the price is fine is not a bad deal, as you said it suffered less heating cycles, and it doesnt matters if it looks bad, i prefer to see the original state instead of the seller "making it pretty" for me
*And you got a texas instrument 411B temperature monitor and some capacitors for free
Thx, i added it here, i hope the description is fine
https://www.psdevwiki.com/ps3/Template:Syscon_pinout_LQFP_100_pins
Anyway... additionally to the description, i consider the confirmation of the existence of this signals in the last syscon models is important enought to clarify some doubts me (and probably some more people) had
As i said before, some of that official codenames are taken from the service manuals of the first PS3 fats models, are not fully documented as far i know, and is doubtful if sony modyed them along the production of the PS3 familly
Just for curiosity sake... as far i see there are only other 2 candidate control signals missing in between syscon (outputs) and RSX (inputs), named "RSX_CGRST" (located at RSX pad AV6) and "RSX_RESET" (located at RSX pad AW5), the first one reset is self explanatory because the name is generic, so it resets the whole RSX, but i cant imagine what means cgrst (it seems to reset CG... whatever that means CG). Please take a fast peek to try to find them, this would complete all the control signals, are 9 in total and you already found 7
Just to be clear... the challenge now is to find this 2 connections in between the squared syscons (LQFP 100 pins) and the RSX models using a 41x41 pad layout
RSX pad AW5 (RSX_RESET) <--- syscon pin ??
RSX pad AV6 (RSX_CGRST) <--- syscon pin ??

I posted this on my last post in faulty thread, I'll say again @sandungas AV6 is tied on gnd on 40nm slim boards.

I'm looking wrong to your config, so I'm working about AV6, it's av7 that we move usually in diagonal and here in slim is directly to ground.

this is not new to me, I've seen ads selling the PS4 APU this way LOL. But the ps3 GPU is the first time I see '-'Hey friends, so i had ordered a "nos"
