I got a 1A 25xx today, min FW 3.5, currently testing 900/1000
75°c still fine 33% Fanspeed (haven't torn it apart and re-pasted yet but with these temps I am not even sure if this is necessary)

currently just Crysis 4th Mission. Any suggestions? I've read acsension is a good one too?
Edit: still works absolutely fine.
Did run around, driven with some jeep and did that tank fight. FPS are absolutely horrendous on this ps3 version of crysis, I can tell you this much.
I think I'll YOLO it
btw the fact that ascension has like 9 Patches (more than 2gigs probabaly) while 3 has like one small one, tells you all you need to know about the quality difference of GoW3 and this one. Jesus

Great, that seems like a good test, I noticed Midnight Club LA runs like trash, I wonder if RSX OC will help there?
Yeah GOW3 is definitely better!
@Tanzu15 I think I want to get a couple YLOD CECHA's, if I can get 3 or 4 for $50 but I'm sure it must be bad GPUs on pretty much all of them, so I'd also have to buy a new RSX and buy all the tools for BGA work. I wish we just got the CECHA here without importing, there'd probably be living ones today
Oh, I assumed it was 4.8GHz because that would be a 1.5x multiplier, not a special value that could possibly be changed to another frequency (if you can find other working values). Now you obviously just said 65/45 is incapable of varying from 3.2GHz, my question is: do you think the 4.8GHz clock is unstable because the 90nm struggles at that speed or do you think it's because of the software itself not coping with the speed difference? Hypothetically if those smaller nodes could be clocked higher for instance (which it can't be), would it be more stable or is it simply a limitation of GameOS?
The FSB gets boosted with this mod to 600MHz from 400MHz. The multipliers stay the same. The original dev consoles had a 4x multiplier (2.4GHz) while the final console uses a 8x multiplier (3.2GHz). 600MHz x8 multiplier results in 4.8GHz.

Oh I see, so dev consoles were 4x600MHz, and retail is 8x400MHz, and the multiplier from the dev console can be applied to the retail 90nm CELL to get 4.8GHz, makes sense!
@Mitsu™@Tanzu15 I tested my 2104B today, currently running 600/750, and I managed to run it with a temp limit in Webman of 60c with the fans hitting 36% while playing Midnight Club LA for a while, is that normal? Fan is usually at 25% and temp limit 68c

@Razmann4k Any specific section you want me to test? I quickly booted it up with a fresh save and I do have drops down to like 20/ 22 when driving around the town, so I dont think RSX OC helps mucht on this game.

This is fantastic news. This means my 850 fully stable PS3s can easily do 900 now since all that happens is it crashes no artifacting due to lack of voltage. And my 950 can easily hit 1000 on core. So it would be 1000/1000. Hopefully you release an easy dummy proof tutorial soon. I've been bored out of my mind.
It will require soldering to gain access to the SYSCON UART and fixing the checksum at address 7fe on sherwood. This has the added benefit of giving you access to the syscon fantables to force the fan to100% in case of a brick. That can help you unbrick. So in preparation for the VID Hack, I'd suggest opening and installing the necessary wires for SYSCON UART. Here's a tutorial for that part.
UPDATE: VID HACKING EXACERBATES VOLTAGE RIPPLE
As you can see the max stable overclock I could achieve without voltage increases was 700/900. And with that OC I would get voltage ripple of nearly 80mVpp. This is not enough to trigger voltage protection, but is definitely well above what a well attenuated filter should strive for. The general rule is 1-5% of the output voltage. So at 1v the ripple should be 10-50mVpp or less. As you can see the CPU Vcore (yellow line) is flat. 10mVpp, which is well controlled by it's filter at stock frequencies. But the RSX at 80mV is now outside the well controlled range. That's without increasing voltage!
850/900 required 1.141v to stabilize. Acceptable voltage ripple is 11-57mVpp or less, but I'm getting upto 120mVpp! And yet this is still not enough to trigger voltage protection.
Yesterday I tried 900/900 and while it was stable in XMB, it was unstable in game at 1.141v.
I then boosted the voltage +0.05v to 1.191v. And that made the game more stable, but there were some lingering black speckeld/glitchy artifacts. So I boosted it another +0.05v to 1.215v. Withing a few seconds of gaining control of my character it freeze for about a second, then powered off.
Unlike most unstable Overclocks, this was getting more and more stable with VID hikes. It's not due to the OC being unstable. It was caused by one of these voltage spikes! Worsening, inadequate power delivery/filtering! The SYSCON errorlog contained a new A0801002 error that had never occired on this console before. That's the error code you get when voltage ripple exceeds the Over/under voltage protection. This model (CECH-25xx) will simply shut off. There was no tripple-beep or flashing LEDs. This is a general HW fault, no different than a YLOD, but SONY changed the way it's indicated on this and later models. @Nascar1243 and I have coined the term "No Light of Death" (NLOD or noLOD) to describe this situation.
Anyway, you can see that increasing the voltage increases the voltage ripple and eventually overwhelms the filtering. I can tell that my RSX filter was not perfectly healthy to begin with. This console has 1124 days of use on it already. So the Aluminum Polymer capacitors that SONY has on here are probably wearing down to some extent and overclocking to this extreme has exposed their wear. It would be fine at stock clocks. In fact I want to get a scope image at stock also. But I suspect thes caps need replaced and perhaps I can add a few extra to help even more. That might allow me to push even further.

That's very interesting, so the ripple at 1.215v was just too much for the caps to smooth out. I wonder if a Frankenstein would be a better candidate for overclocking & messing with the VID tables, if the NEC TOKINS (assuming they're still healthy) are better for smoothing out the ripple? I mean, even if they are the same, the VRMs on the CECHA were designed with a more power hungry RSX in mind that naturally ran at such voltages already, and the beefy heatsink should be more than enough to keep the 40nm cool even with a 250mV increase. I could of course be totally wrong though.
the VRM for a 90nm model would have beefier power delivery and filtering. The tokins are getting old and dying, but I have made tantalizers to replace them. Theoretically a frankie would have more headroom both in terms of VRM and thermally, due to the OP heatsink and fan.
Once I've concluded my testing on this 2501a I'll move onto the frankie. At the conclusion of that I'll write up a summary and tutorial. That's the other half of this methodology. When I'm satisfied both mullion and sherwood behave as predicted I'll feel better about letting you guys brick your consoles.

Thanks, can't wait to give it try after seeing what my RSX can do without extra voltage. Yes, I saw your video on the tantalisers as well as your 360 RROD and YLOD video, the tantaliser utilising multiple capacitor types to combine their strengths across the frequency range is a great idea, and even better considering that you probably could've made more money from selling them if you didn't debunk the TOKIN apocalypse, thank you for doing so and thank you for the sound knowledge you've given me and many others regarding the true cause of the 90nm RSX and 360 Xenos failures (packaging of the die to the substrate using the wrong type of underfill).
Also, you mentioned those terrible 'fixes' in your video, and I can attest to one of them: 2 yrs ago, I was stupid enough to put an eraser under my Cell on my old CECHL because it was running hot! (not even YLOD, just hot... facepalm) Worse still, my Cell and RSX were already delidded a long time before this, I just used crappy thermal paste because I ran out of my good stuff after using it on my PC but forgot I used the cheap stuff. Funny enough, when I booted it after putting the eraser in, my temps dropped quite a bit, but about 10 minutes in it black screened and YLOD'ed. Upon opening it up and inspecting it... my CELL die was literally CRACKED in two! Upon reading the syscon, it was A0203010. It's scrap now, luckily I got a CECH21xx for cheap.
