PS3 PS3 Undervolting Thread

On thick consoles there are CFW, on thin ones there are HEN.
It is impossible to make the voltage lower, I achieved the minimum experimentally.

There are still about 20 thick ps3, different models, I will modify them too.

That's right, but your first one is a CECH-C witch means it's a Fat Edition full CFW support.

Witch CFW are you using on the C Edition?

Isn't TLoU capped at 30fps? That would also limit the stress test. If I may offer a suggestion: try God of War 3. It's capped at 60fps, but it never actually reaches 60, so it pushes the hardware to its limit more efficiently, IMHO, because it doesn't limit the rendering to 30.

Not necessarily true, Crysis 3 is capped at 30fps and it is possibly one of the best game to street test hardware on the PS3.
 
Update:

PS3 Fat CECH C

I got it stable on CELL with 1.0750v [20]
And RSX on 1.1750v on a OC CFW 600/750 Mhz [3B]

I didn't understand your question, translation difficulties. What do you want to know about my console firmware?

Normal CFW

Thank you very much :)

My next great one:

PS3 Slim CECH-250X
Mini IHS Mod
Case Mod
Sherwood Vid table
CFW Evilnat 4.91 OC
CELL 0.86250v [75]
RSX 0.84375v [78]

Totally stable and again way cooler.

Best regards
NSC

After testing 10 different COK001 and COK002 boards, I can say pretty much every A/B/C/E PS3 can run CELL and RSX voltage at 1.15V A few lucky boards were able to run 1.125V. None of the boards I had were reliable at 1.075V and all would freeze or blackscreen at startup below 1.075V. Default voltages were between 1.2 and 1.225V on my systems with the exception of one truly terrible RSX that was running 1.3V

I think I've got a lucky board. Mine CECHB can run TLoU with 1.125V on CELL without crashing (I tested it for 2 hours). I left RSX at 1.1375V for stability.
 
Hello. I came across an unusual cechb00 board with only 35 days of battery life. I was only able to lower the SELL voltage to 1.1750 3V and the standard GPU voltage of 1.1150 1E. All attempts to lower the SELL voltage below 3V resulted in freezes in games like TLOU.

It is silicon lottery. 3v means 3B I hope)))

Hello everyone!
I got a CEHC04 (~11 days runtime) COK-002 and I have soldered Syscon wires for a nice, permanent setup in order to test values around.

I was able to undervolt it from CELL ? (didn't bother to check with a multimeter) to 1.0875V and its bin 3 toshiba RSX from 1.3125V to 1.05V.

Tested many games for hours such as GT6 demo, TLOU, MGS4, Yakuza (PS2) it ran perfectly fine without any freezes. Temps stayed under 55C on both chips during heavy gaming, with the RSX being cooler with 28-30% fan speed.

Now sadly whenever I turn on the console on a fresh new day after it has not been powered on overnight, I get YLOD in form of 1601 and 1701 whenever I launch any ISO. Turning it back on again lets me run the ISO again for hours with no issues. Sometimes it takes 2 times, sometimes once

I tried raising the CELL to a known stable value I once used (1.1125V), but it sadly still did it. So as a last resort, I changed RSX to 1.15V (which I knew was stable) and as of now, under the same testing conditions it loaded the ISO fine first try....

Has anyone met this issue before? I can only find one reddit post about it kind of unanswered [emoji17]

I guess its the RSX being kind of too low when loading a game from coldboot not being able to process the sudden "jump" on load so I will raise it up to 1.075V or 1.0875V and see..

I had such errors after undervolting with tokins. After tokins replacement - no errors anymore

Oh okay, so it isn't something bad? Its just undervolt instability due to nec/tokin condition?

Like can I just turn it back on again and play normally afterwards, the ylod once or twice wouldn't annoy me tbh I just worried it was something serious
