If the voltage is less, it is likely that RSX will not work, but if it is too excessive it is also not good, because RSX will heat up easily, as long as the overvoltage is not too high it is still ok, during the installation of cxd2991, until now there has been no problem with the voltage
Yes, cxd5300x, cxd5301x, cxd5302x can be swap
this is pretty amazing! I can follow the explanation fairly well, but the only image that loads for me is the first one, where you wrote down the location of the clock. Can anyone else see the other images ?Greetings to all friends on the forum
This time I will share my experience in analyzing ps3 machines, the method I use is arguably very simple and uses simple tools too, I have been using this method for the last few years. I just started so that you don't feel bored. In the analysis that needs to be held:
1. understand the process / work stages of the machine
2. Understand the working of IC
Below is a process / steps that must run from the start of the engine until the engine comes out of the picture, in the future I will mention that as a "rule"
1. CellBe to Syscon, --no--, shotdown
2. Rsx to Syscon, --no--, shotdown
3. CellBe to Rsx, --no--, shotdown
4. CellBe to RamCellBe, --no - blank
5. Cell be to nor / nand (boot os) - no--, shotdown / blank
6. Rsx to RamRsx, --no--, blank
7. AV / HDMI output
In the future, the "rules" could be added to be even more detailed (if someone is diligent in looking for them). This "rule" can be visualized, there is 1 point in each machine that I usually use to visualize the "rules", this point is the engine clk, in the future I will call it "clk pulse", I will take an example from the dyn-001 engine.

Below is an example of a "clk pulse" (dyn-001) from a running / normal machine
From the video above we divide the clk pulse into 3 steps (the first beat continues to stop briefly (step1), the second pulse continues to stop briefly (step2), the third beat is just a little bit then silent (step3) -
Step 1: "Rules" No.1-5
Step 2: "Rule" no. 6
Step 3: "Rule" no. 7
Pulse clk for Rsx:
-Cxd2971x there are only step1 and step2 (after that the image comes out)
-Cxd2982x, Cxd2991x, Cxd530xx has 3 steps (after that comes out the picture) Hopefully you won't get confused
sorry wrongly pressing the post button, the explanation is still not finished, ok we will continue again, I will give an example of a problematic clk pulse
from the video above, you can see clk pulses repeatedly, I usually call it "looping"
the symptoms are when the engine is turned on:
1. no display / blank
2. When the reset is pressed it cannot beep 1x
3. The LED indicator on the HDD is not blinking.
Such conditions entered in "rule" no.4 there is a problem with the connection from CellBe to RamCellBe the problem can be:
1. the RamCellBe didn't get the right voltage
2. Bad tin ore that disturbs the connection, especially in the CellBe section (needs to be reballed)
3. damage to RamCellBe ic or damage to ic CellBe
I will give the next example, this time the problem occurs in the Rsx section
here you can see the pulse clk step1 has passed, step 2 only goes up a little and then remains silent, the symptoms will not display / blank, hold reset can be 1x beep, hdd light blinks briefly, this symptom is included in "rule" no.6 there is damage in the RSX section:
1. RamRsx is not getting the correct voltage
2.The tin ore that is already ugly (need to reball)
3. Damaged RSX IC or RAMRSX IC
and there will be another pulse, if we are diligent in looking for it.
Until here, the explanation that I made, hopefully it can help a little to analyze the damage to a ps3 engine, no one method is perfect, but at least it can lead us to fix engine damage more directed. I'm sorry if my explanation isn't clear, or the uploaded pictures and videos can't be opened, because this is the first time I'm trying to upload a video.
best wishes to all ...
If you right click the images and select open in new tab you will be able to see them.
thank you! that worked.
It's a video of him using an old school volt meter with an analog dial that shows voltage (like a spedometer). What I've always liked about thoes style meters is that you get more information from them that you do a digital readout. Sure it's nice to just read and record a digital number, but a dial can pulse up and down and you get a feel for what's happening over time. So in that way it's like an oscilloscope. It doesn't plot it on a graph, but the voltage pulses he's talking about are roughly equivelent to discrete steps you'd see on a graph of voltage over time, which is what an oscilloscope does.
Let me pull up an example of the startup sequence that I recorded on the CPU/RSX tokin testpoints I was using...You can see there are discreet steps in the startup sequence, but the time base I'm looking at for this are very brief. He's using a different test point and talking about voltage pulses corresponding to different events. But the idea is the same.
The difference between a 40 and 80 step number is about half a second. The Startup Sequence (POST) normally takes less than half a second to complete and then the bootloader will startup the console. That last plateau (where the CPU voltage in Yellow drops) wont happen if ther's an error that prevents the console from starting. There is always a high voltage spike on the CPU just before shutdown, either caused by a YLOD or normal pwr down.
If there is a bitraining error (4034), it delays the startup sequence (POST). Usually a 40 3034 causes a 1-2s YLOD. If it takes longer, say 2-10s it could have made it past bittraining and is having problems in the "PWR ON" state, step number 80. So you'll get an 80 something error. I had a 2-10s YLOD that triggered 80 1002s. The SYSCON didn't show the startup sequence in the "lasterrlog" because it completed the startup sequence (POST) without error. It only returned the 80 1002 error, because the error occurred during normal operations (a voltage spike that triggered a 1002 and shutdown event). So step number 80 occurs after about half a second, unless there is a bittraining error that causes the startup sequence to be delayed.
Anyway, I just found it interesting that these "plateaus" as I called them and "pulses" as @botakompong calls them are useful in conceptualizing what the console is doing and where it might have messed up.
lol! so true. I love playing games, but I love tinkering with them just as much.
Sorry, more questions, now that I watched the videos a few more times and understand them a bit better now. I noticed that the "pulse" happens at a certain threshold... On the 3 videos where things were normal, that threshold was reached 3 times (Just as you described). On the bad cellBe, it almost reached that threshold, but never quite made it, it just kept trying in a loop.. And on the bad rsx one, it got stuck at that value at the second pulse. What is the voltage value for the pulses?Greetings to all friends on the forum

If you pay attention again, the CLK pulse is still at the beginning of the "rule" no.4. the connection from cellbe to ramcellbe, later I will give an example of a clk pulse that is in "rule" no.5 at bootOS, we don't discuss the voltage here, so the actual voltage value is not needed
Is kind of signal (frequency kind) a part of spi communication. Its kind when people tried to understand the problem looking at nec tokins with oscilloscope. A fluctuation/spikes related will say many things in different ways that op observed in his way and described.
