Silicon lottery is the biggest factor in here. I've had A01s with CELLs that were stable at 0.99-1.00V, whereas others did need 1.15+ to achieve stability at stock.

It also works on SS. Just follow the guides for Sherwood and use those VID tables. 0x50 for Cell and 0x51 for RSX.

It's definetly the power supply. I've got a couple of ZSSR PSUs and one of them has especially bad coil whine. It's annoying and I had to change it. I find APS226s don't have this issue. I'm wondering if using an APS231 on undervolted consoles is a viable alternative now. Edit: I've also...

From what I can gather, a 40nm RSX will request 0.95V by default. However there have been tests where it can go below the minimum VID table for Mullion (0.8V)

While it in theory could be done through CFW I don't recommend doing so because if you apply unstable settings you'll soft-brick your console. Everything should be done via SYSCON.

IIRC , and correct me @RIP-Felix if I'm wrong, but the voltage mod is for the GDDR, to prevent burning it. However, it would also help. Does anybody with 65 and 40nm RSX native systems have the default voltage for those?

I would assume yes as long as you have R/W access to Syscon . However I wouldn't recommend it because you can softbrick your console if you set an unstable voltage, until you go into Syscon and rewrite to a higher value.

Which were your temps before the procedure and which voltages did you achieve?

From my testing lower CELL temps also led to (slightly) lower RSX temps as well. Even though they are in theory cooled by separate heat pipes, they share thermal dissipation on the PCB and through the heatsink (because of the single fan and all) Sure if the paste is bad it will need replacing...

I personally don't own a Sherwood system (..yet) but I assume the addresses must be similar (RSX address -1 ). Will be interesting to see how later systems react to the CELL undervolting, though this is huge for Phats because this will prevent senseless kills by failed delids (ask me how I know).

I replaced 2 Tokins and the ripple was so much better: It allowed me to go even lower, and discovered the true crash point for my CELL (The point where a BE Deadlock occurs). It was 0.965V I therefore moved it up a notch and it's been stable so far at 0.98V measured. @RIP-Felix IMO the...

Yeah, it seems this one is due for TOKIN replacement on CELL as well because same 1001 error while loading TLOU even at 1.2V VID. However, here are some scope measurements at 3 different points on XMB: 1.20V VID, 1.13V measured. 1.12V VID, 1.06V measured 1.05V VID, 0.99V measured The ripple...

I will provide scope measurements later but I think it's more likely the Power delivery system might be also finnicky. The console I'm testing is a CECHA01 (older than the one from the photops on top) with a runtime of 182 days (!) I did have to rescue this one with NEC TOKIN replacements for...

I'm going to check the voltage on mine from an oscilloscope. I did manage to go even lower, at a set point of 1.0375V according to the VID table, but a real voltage of 0.988V. It was surprisingly stable with not as demanding games, but TLOU triggered a RLOD of 1001 (BE Power Fail). Hence I'm...

I will do it later today, I found the address for CELL VID. It's 0x3110.
