RSX swap didn't help, error is stil 0xa0403034
RSX swap didn't help, error is stil 0xa0403034
since I think there's a giant blob of solder below one of the caps legs in the negative pad, which raised the metal plate just slightly enough to cause issues with the RSX
Hello everyone,
I thought of talking about my CECHC04 with a weird issue as I couldn't find much on the Internet about it
Basically, it has around 10 days of runtime, I have repasted it undervolted etc. Rsx is under 55C Cell too this that still using its original NEC/TOKINs, no 1001 or 1002 errors when playing games, im using a custom syscon fan curve
At first I undervolted it to CELL 1.125V and RSX 1.15V by using the syscon clamp method. It ran fine and stable I played Yakuza and Yakuza 2 PS2 mode fine with it
Its like when I soldered in permanent syscon wires, I was testing around further with undervolting and my limit was CELL 1.0875V and RSX 1.05V. Many games ran completely fine for hours so I deemed this to be stable (?)
Now here comes the issue, whenever I turn on the console on a fresh new day (overnight console was not powered on, no standby) it would boot normally to the xmb, but as soon as I load any ISO, homebrew or app it goes to the black screen, HDD light and wifi light blinks for a little bit, then HDD light turns off wifi shortly after...
... and im met with YLOD, syscon errors 1601 and 1701 in the same time frame as a pair
Now here is the thing, when I turn it back on again and try to load whatever gave me ylod it works fine and I can use/play whatever i launched for hours and switch games etc. Till I turn it off myself. Even the most demanding games out there work absolutely fine
Now out of common sense I thought it would be a udnervolting issue. So I raised CELL firdt back to 1.125V and it still did it
It was up until I set the RSX to 1.0875V that it didnt do it anymore BUT I once left it without power for a night, a full on day and a half a day and the same symptoms happened.
I remember also that when it YLOD i was on my phone sesrching for anythinf about it and around 10 mins after I turned it on and it took me another try to make it load fine
So it is definetly something time related.... but what is going on? 1601 1701 are so generic that it tells you absolutely nothing sadly
Im running a noBD firmware with solely the Daughterboard attached (previous owner botched connector clamp on mobo and a few pins) Im able to load ISOs with my setup but I cant remarry the daughterboard/drive
On webman I set the xmb to have 350/400 clock speeds and apps, games 500/650
My CMOS battery is dead but im about to replace it with a new one by resoldering those wires to a new CR2032 battery.
My SD CARD reader is kind of weird, i checked the ribbon cable and it seemed to be fine but for some reason the memory stick pro light is always on and the CF light has a faint glow to it, Sd cards wont read (back then it did work fine so it must be something during reassmeble)
I left it disconnected as I was worried it could give more issues?
What could I try next to diagnose this issue? Its like can I just cope with it or might it lead to something terrible with time...
Yes, its the next thing I will try. I removed that underclocking on XMB little gimmick as I think the Values jump from low to stock values when entering something and it might stress out the RSX... I noticed different symptoms after doing thatYour RSX undervolt is too low. The 1.0875v setting, which is closer to 1.045 if you check with a DMM, is too low for a 90nm RSX. The other issues are common undervolt problems where if you leave it turned off for a day or two you can get YLOD or really odd behavior from the console. I have always fixed it by increasing the RSX voltage.
If you want to prove or disprove its the undervolt just set it back to FF and see what happens, dont do half a job and raise the setting slightly and say its not the problem. You should set both to FF, verify system stability, then undervolt 1 processor at a time with long testing sessions. When everything is stable unplug the console for 1-2 days then retest.
That melted plastics is probably from a "oven reflow" trick. The temperature sensor will shut the console down way before such temperature is reached.I recently got an interesting CECHB00 from Japan. Was listed as a working console, but when I received it that was only kind of true.
Noticed the console had been opened, it powered on, booted to XMB then after about 45sec it YLOD. I decided to pull it apart and get syscon errors and found an absolutely atrocious attempt at replacing the back tokins with capacitors. but thankfully no shorts or major damage to the board. Pulled the board out and found the entire cooler shroud was melted/warped, this lines up with what I found in the syscon errors later.

Pulled syscon errors to find 1001 and 1002 being the most recent, but the backlog also showed signs of a major thermal event (hence the melted cooler shroud) and 3034 errors. Found it interesting to see south bridge thermal error 1214, followed up by 3034 shortly after. The following codes show the console got really hot, throwing pretty much every error for thermal possible.

I decided to throw some proper tokin replacement boards in, swap the entire cooler for a non melted one and even undervolted it a bit. So far its working flawlessly, I'm going to keep using it and see if the 3034 comes back! Has anyone seen a 3034 caused temporarily by a major overheat?

And unfortunately without a proper fix it's almost guaranteed 3034 will come back
Is it just the cooler that's warped or the rear panel just below the serial number as well?I didn't even consider someone would try to put the entire board and cooler into the oven as a unit, that is absolutely absurd and beyond lazy, even for a half assed attempt.
I guess time will tell!

It's more likely that instead of putting the entire console in the oven they instead stuck a hairdryer or heatgun in the back and just left it on for several minutes.

403034 does not always mean a BGA defect. Improper voltages can also can 403034, so a overheating system could theoretically throw a 403034 if something got too hot and output an improper voltage. From the look of it and all of the error codes its very likely someone wrapped this in a towel and tried to fix it by overheating it.
