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

Yes ,I play 750/1000 for a long time on my 2504B and its stable aslong you have 60degree,and i test the clocks on another 2504B with the same result. And in best case you deleed the heatsink on the RSX and optimise the Thermalgrease for the Vram because you dont see wat Temps the Memory on the RSX reach.This is also the point where you can damage your VRam over a long period of time!.
In another case I had the opportunity to test the firmware on a Frankenstein PS3 with a CXD5301DGB RSX, this console gets bricked.
At the moment I can only assume why this happened, I think it's the memory clock, as the memory can be different for the different 40nm RSX models.
but i work on it to test some 40 nm RSX to get a list wich 40nm RSX make what clocks.

Share some footage using the FPS counter plugin displaying the fps, clock speeds and temperature.
 
honestly i would be fine with 650/800, because that's what a 7900 GTX ran at.
Thinking about it, the PS3 would need double the memory clock considering it has half the bus-width compared to the desktop 7900 GTX, but i think 1600 on the memory is slightly unrealistic

I clocked my console higher bit by bit with forced high temperatures under load to see when errors first occur. first the GPU then the memory. I still have a pre-programmed patch tool and can provide some firmwares if someone wants to test it for himself
. I'm interested in your results and which PS3 model and which GPU you have.its all evilnat 4.90 pex

Yes please per PM. I have a 2104B currently.

Also the memory should be cooled by the main RSX heatsink. Since the GPU and the memory are connected to the main heatspreader

the heat connection from the memory to the heatspreader is different there is a bigger gap .and might the heatpast not cover up the hole surface of the memory Chip.but its one of my next missions to look closer to that and deleed my RSX an try some expensive pads or fresh paste.

i like also try to capture it on a PC and try to visualize the difference in a video,but i dont have any capture device at the moment
and its a bit rar to find the scenario were the OC shows its full potential,the CPU is a main bottleneck in lots of cases.

Would it be possible to get access to your automated tool?

I meant as a maximum setting in whatever scripts he wants to provide. Of course each console has to be tested in steps.

Here are few nice games to test:
-Need for Speed Carbon as it is mostly GPU bound and it has an unlocked framerate.
-Gran Turismo Concept HD as it's very sensible to GPU instability.
-Need for Speed Undercover in the Garage to test how high the temperatures get. Enter Garage and just let it sit with the Overlay open.
-Gran Turismo 6 with heavy rain at night with opponents, just to punish every PS3. Still get drops under 40fps with 650/750 active.

Hello! I'd love to test some higher clocks as well. I have a 25XX Slim with CFW from Evilnat.

which clocks do you want to try in general, maybe with some limit?

I'm a huge PC overclocker and be 100% sure, that it would be better to increment Core/Mem one by one, so make a config for 625 core and leave mem on 750. Make config with 600 core and 775 mem and so on. If you need help making the script I'd be happy to :) Let's unleash the power of our PS3s! Where's the beer emoji? :rolling:

You can only do 50 MHz steps. I think Haxxxen has recognized that you need all variants to explore the maximum clock speeds

Only 50 MHz steps? Damn. Those are big steps :blue: I couldn't count on both hands how many times I got a stable 1232 and not a 1235 for example. Too bad :blue:

Yes, that's a little tricky i know what you mean , that's why I let the console run hot to see instability as early as possible
It's maby inevitable that someone will brick their console :applause:

If you're not playing with voltages, the only thing that can happen is a crash. I'm also sure the PS has some internal current protection/limit so there shouldn't be a problem. ;)

Brick can still happen if the RSX crashes instantly so you cant reflash the firmware anymore. (If you go too high)

I'm currently at 700/750 and haven't had a single crash. (at a max of 84C on the RSX)

You could only do 1200/1200 in that case. You have to be a little conservative on the PlayStation with the clocks

EDIT: Okay 750/750 is unstable on mine. I get graphical glitches and hard crashes. Someone needs to make 700 core with higher memory speeds for me. (40nm 5300 RSX - 2104B)

Hello, yes please. I think GPU could reach 900 with a shunt mod (idk if it's possible on RSX tho)
OCing the memory is generally safer, as it usually causes artifacts before hard locks (at least on the PC generation of these cards)

This is the order of testing I'd follow to find max safe clock.

I'd game for a few hours/days on each setting to be certain in stability.

Code: 
550 - 650
550 - 700
550 - 750
550 - 800

550 - 900

There's no 4.91 OC cfw yet?
