PS3 Project RSX Boost: Overclock your Retail PS3 RSX Speeds (ps3 cfw only)

Hello, please someone has the last version
4.91.2 evilnat OC 700/850 ? I don't know how to do this, I believe this OC version is OK for my PS3 Slim cech2511a. I'm using 700/900 but I don't know it is a safe zone.
Thanks for any help.

you should be safe ! From reading Rip Felix & Mitsu, 700mhz core and 800-850mhz vram is more than sufficient, anything above is diminishing return. I just facepalm myself seeing people on here brick their system in pursuit of trying to squeeze and extra frame or so smh

I may have already made this one, but I made it again anyway.
and this is the final release correct? not beta 17

yes, final release.
 
Also I realised everytime I change the voltage I need to fix the checksum is that right?
if you mean the checksum of the pup, I'm not sure. afaik, the pup does have a checksum, so people worrying about corrupted updates, should be okay. packages at least have them to prevent corruption, so it would seem odd that sony wouldn't have them for pups. however, if you zip up the update, that will ensure it's good without needing a checksum (if sharing). not sure if you meant that though.

No I meant the uart syscon eepcsum
 
i think the best setting for ps3 slim 25xx its 700/850 cause i try the 700/900 to many lag to game cause optimize software, the original its 500/650, I think the numbers should be the same, not evened out, like 750/850 not 700 or 800 or 900

I see your point and I will always recommend 700/850 as the optimal OC for a PS3 (25**).
That said, if you want to keep the same core/VRAM ratio, that's not exactly how it works.

500 / 650 = 5 / 6.5 ≈ 0.7692 (ratio)

So, here :
VRAM= Core/Ratio = 700(MHz core) / 0.7692 ≈ 910 MHz VRAM.

700/900-925 would be better if you really want to stick to the original ratio.
(I still think that 700/850 is better, though :P )

Unrelated, but like Dhmhtrhs, I'm also testing underclocking. Not on a FAT, but on my main Slim (2504A). Why ? Well, just for fun ! ... No, that's not the only reason.
These days, I'm mostly playing PS1/PS2 titles, so I don't need any overclocking at all. I don't even need 500/650, as 400/550 seems perfectly stable (at least on this PS3, so try it at your own risks, as always :P).
I've observed approximately a -3°C drop on the RSX compared to 500/650 while running PS1 titles, with no drawbacks so far. I also tested some PS2 games, and the results were the same.
You might think that a ~3°C reduction isn't worth it, but I've seen crazier and riskier mods/methods being used for the same or even worse results, so... I'm fine with this.
Even the CELL runs slightly cooler, thanks to the reduced heat generated by the RSX !

• While playing Xenogears :
- At 500/650 : CELL 57°C / RSX 60°C
- At 400/550 : CELL 55°C / RSX 57°C

Same ambient temperature, same fan speed.

Of course, this is much more interesting for a 90nm FAT.
However, if it proves to be perfectly stable after further thorough testing, I'll likely keep it on my Slim for PS1/PS2 games and other non-RSX-intensive tasks.
For PS3 games, I'll use 500/650 as long as there are no major performance issues (or in cases where overclocking doesn't help anyway), and switch to 700/850 when a boost is needed :y

I can do it for you am based in uk London greenwich

?

Lol I just saved the console without even opening it. So I put the console inside a freezer for like 20h and make sure the gaming room was so cold so I turn the AC on and let the airflow point to the console location. I turn the console on and go to the safe mode and update the firmware and it worked now lol.

Xenogears - good game. The game is $5 on the PlayStation store iirc, but it's like $200 in disc format. I got the game on PSN, then used the memory card adapter to move my old save to the PS3. Well worth it. I think Mitsuda did the soundtrack, love the last stage song.

I plan to try this, but I prefer to wait until I find a second 25** to experiment on (There are many 20** available but 25** slims are a bit rare where I live. ^^').
But yeah, combining a moderate underclock (with minimal, reasonable, impact on performance) and undervolting on a 90nm FAT model would significantly reduce heat.
Logically—I might be wrong—but an underclocked RSX might allow for even further undervolting. This is something to explore.

Yep, Mitsuda absolutely nailed this soundtrack ! One of his best works !
If you loved Xenogears, I highly recommend exploring the other Xeno games.
The Xenoblade trilogy is easily accessible (if you have a Switch, of course), while the Xenosaga trilogy is a bit harder to play legally.
Like Xenogears, Xenosaga also suffered from development issues due to the publisher—but it's a masterpiece nonetheless.

The Xeno series has definitely become my favorite JRPG franchise ever (and I've played a lot of JRPGs) !
There are plenty of other great games out there, of course, but nothing has ever drawn me in emotionally as much as these.
The stories, world-building, characters, and soundtracks are on a completely different level.
That said, NieR and NieR Automata are strong contenders too.

interesting test Mitsu, i will try my ps3 slim 2101B to see if there are any differences on ps3 games, sounds interesting to test, i do ussually play ps3 games only so far, so it will be good to have great and stable temps and not to lose too mucho performance on the way

jaja we are both that play those xeno series, i hope that xenoblade chronicles 4 gets released soon, and also maybe an anime or game that came to give continuity to Nier Automata anime ending, it seem to be a great story for whats coming

That wiiu Xenoblade x comes out in March for the switch, I believe. @Mitsu™ , your handle isn't by any chance named after Mitsuda or is that a coincidence?
