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

just my assumption, but when doing resolution changings, I think lv1 does sth like a reinitialisation of RSX. so maybe with right hypercalls it could be achieved, but this is over my skills and needs expert lv1 reversing (using picard's ida databases)

So can we test it poking the lv1 to change the clock values and then changing the resolution to see if it works?

no, cause the RSX initialisation only happens at system startup and after that, lv1/RSX never ever gets reloaded. if you poke and reboot lv1, you obviously will loose any modified data. you cannot patch the multi on fly, cause it is not like on PC, where gfx configuration data is located in RAM. this data is isolated unfortunately.

though, doing resolution changings, you will loose tv signal for a short period of time, which I think is sth like a reloading of RSX configuration

The pattern is not even found in LV1 memory.

I think that in previous posts was mentioned about the option of include another lv1.self patched with OC in the blank area of ROS in CoreOS.

To swap LV1 it would be required to write only one sector in the file table of CoreOS to make lv1.self offset point to the patched file or to the original file.

Obviously this is only a theory that hasn't been proven but it sounds like an option to explore for devs with hardware flasher.

I think this solution is viable, but it is still limited to two frequencies and there is no way to test the RSX limit.

An ideal solution is If the overclock failed and the console was unable to start, the RS bank could be swapped to avoid a brick, so we could keep one stable for safety and the other one for testing, for example.

Is your 800/1000 still stable? And how many games have you tested?
 
And even tho' your cooling kinda sucks, you're able to pull these high frequencies...that's insane! Lucky boy!! :'D
Even with 55°C, mine stops at 700 :(

So would be 2501B be capable of this OC? Or is it just luck? Mine is a 40nm right?

I recently discovered a friend who owns the exact same model as mine, CECH 2511B. Interestingly, his console is handling the same overclock as mine, running at 800/1000MHz without any issues.

It appears that the
'
2511X models can handle 800/1000MHz (40mn) - Me and @
250XX models can handle 700/1000MHz (40mn) - @Thimblewad
21XXX models can handle 650/800Mhz (40mn) - @cha0shacker
200XX models can handle 700/1000Mhz (65mn) - @Mitsu™

However, we need more examples to confirm this

Even between same models it can vary.
So the best advice here is to increase values step by step, 50MHz by 50MHz (for both core and memory) and see how your PS3 react.
Do not install 800/1000 directly. Better be careful (I know what I'm talking about :nightmare:).

You can buy a flasher, i found it cheap from china.

Small correction :
200X models (65nm) can't handle 700/1000MHz at all (brick).
700/800MHz at best from what I've tested.

Yes, that's a solution.

Man and I'm guessing no one knows how to increase voltage?

This is some solid data. Sadly it's hard to test when the risks are high of bricking. I'm still on 4.89 evilnat OC. Aldos, kinda confirmed that cpu can be overclocked too. Is that true?

Bioshock InfiniteLess frequent artifacts.

CECH-200X700/800 Mhz

@XDeltaOne me and @JoeSapecudo want to test 850 and up on our consoles. If you have time :)

Hello, I'm new here, I created an account just to help with this topic and help the ps3 community, and as a lover of Overcloks, I would like to test cloocks higher than 800/1000
I know the risks and I'm aware of the consequences, but I intend to see how much my 2511A can handle, if it's not too much trouble of course.
And I would like to thank everyone for the excellent support for our beloved PS3!
