Comment on Xbox 360/PS3/(to a lesser extent) Wii owners represent
DacoTaco@lemmy.world 4 days agoYe no, ive have a ps3 that ylod which i reflowed back to life. After it was working again i started digging and the temps the core was reporting wasnt even close to the ihs that i measured with thermal couple. Also the thermal paste is on top of the ihs, not under it and it wasnt soldered in place. Early ps3’s did cook themselves. Less than 360 by a long shot, but they still did!
Also, side note, its funny how some 360’s rrod was not due to the heat issue but can also be caused by power supply failure or the plug being faulty. Thats how i got and fixed my 360 🤣

If it’s a reflow, your PS3 is running on borrowed time. A reflow heats up the chip enough that parts of it expand enough to make the GPU work again temporarily (the solder bumps on the bottom of the silicon attaching it to the interposer line up their cracks again), but eventually you’ll be back to square one. The real fix is to replace the 90nm GPU with a later 65 or 45nm variant that has the fixed design (search up “PS3 frankenstein mod” for more). There is thermal paste both under and above the IHS - the one under for taking the heat from the silicon up to the IHS, then the top layer for taking it to the heatsink. Here’s an image of a delidded RSX and Cell to show (apologies for the quality, was the best one I could easily find). Image
PS3s did cook themselves, but not to the extent of the 360.
It is funny to see how there are probably so many misdiagnosed 360s out there with bad power supplies that have been subjected to being bolt modded (shudder) or something. It doesn’t help that the three red lights just mean “general hardware fault” without doing the button combination to get further information. I guess at least more helpful than the PS3, whose diagnostics were only made available recently due to a key being cracked.

I know what i did to the ps3, and i know what needs to be done. I barely use the ps3 so its fine for my case. The real fix can also be to redo the ihs so the solder doesnt crack or get damaged again because of heat. Also, ps3 also got a lot easier to debug with syscon, which was also only (relatively) recently descovered. Sure made debugging the ps3 easier haha. Ive left the connection available on my ps3 for future usage hehe
