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

Testing:
PS3 2000+SSD+CFW 4.90 OC+TEMPERATURE FIX(hardware).
RIDDICK, param forced to 1080p, perfect, fps, both games.
HAZE, param forced to 1080p, perfect, more fps, textures, nice.
RAGE, perfect, no more texture popin.
RDR, full crash and turn-off with blinking red light.
Edit: dont worry, no damage, turning on right.

I have the 4.88 OC version, should I upgrade or its basically the same performance ?!
 
Hello, I use a CECH 2504B with the Evilnat 4.90 600/750 OC firmware. And it works great. That's not enough for me, I would like my console to have proper overclocking (preferably with water cooling). Does anyone have experimental firmwares or LV1.self with higher clocks?
 
afaik, 600MHz core and 750MHz ram is the last stable clocking that works. though, there are posts saying that even this OC isn't stable on specific games (Red Dead Redemption was one of them)

though, if users want to do their own testings, I could add higher clocks to mfwbuilder

edit
now I rethink of it, probably won't do this, cause it could harm the PS3 to the point, where you cannot re-install firmware without a flasher, cause of instability issues

Yes. The hardware flasher is good. They are not that expensive. I would be happy if you could give me something to experiment with. I am very interested in finding out whether the RSX is reaching its limit due to poor thermals or a lack of electricity .are there parameters in the firmware for the RSX Voltage you can change?

tbh, why stressing RSX even more, when it already has too high failure rate, especially on backwards?
but this is just my opinion.

about voltages, for retails it is still unknown afaik, where it is done
I can provide you in pm higher clock rates though.
 
Extreme overclocking is always a bit pointless. You only do it because you can. And I'm concentrating on the 40nm rsx, from experience it only has to scale better because of its smaller design. Also, 30 fps is a big difference to 25 (from the subjective feeling ).and With bioshock infinity you can disable V sync and sometimes get 40-50 fps.

I think I can't PM you because I'm new to formu.or I just don't know how to start a conversation, can you please?
 
Don't overclock the RSX models with the defective underfill material because it will breakdown even faster due to the higher current with the OC. That would be all models with a 90nm RSX (CXD2971) and the models with the first gen 65nm RSX (CXD2982). Second gen 65nm RSX (CXD2991) and the 40nm RSX (CXD5300) should be fine.
 
I'm currently at 750 MHz RSX with my Slim:anonymous:. With the original cooling, always with a 39-41 percent fan. The temperature must be in the range of 65-68 degrees because otherwise small image errors occur, I haven't had any crashes. So far I'm quite satisfied 50 percent more. I didn't measure any frame rates, but it feels very smooth at first. But there are still fps drops due to the CPU. Later I would like to deal with the Vram clock and build a water cooling system and experiment a little more. If anyone else manages to change the clock of the CPU that would be fantastic.:pig:

CPU was already done but so far only on DECR units by raising the FSB to pre release levels. 4.8GHz was done but the XMB did crash a lot.

wow. is that because the Dev consoles have different hardware? I would be interested to know whether the FSB clock can be changed via the firmware. Is there someone who knows about it?

Btw how did you raise the clock to 750MHz i thought the available clocks only go up to 650MHz?
Because i may want to test a little bit on my 2100 Slim. 40nm RSX should be good for an OC. And the memory hopefully too. What clock do you run the memory at?

haxxxen made it possible for me. He created a few files with different RSX clocks that I can use to patch my PS3UPDAT.PUP. I haven't tested the memory yet, it's at 750mhz.the memory is the next i will Work on. I can try to provide the data later.

It really shouldn't matter because the voltage/current draw is not being modified. This is an old school nvidia chip, before GPU boost that was introduced with maxwell. There is a max defined voltage for P0 clock state and it will not exceed that unless the vBIOS is modified. It comes down to the ASIC quality of the core and memory dies at this point. I'd argue proper cooling of the RSX is a way bigger factor in preventing degredation aka limiting the delta between system off and load operating temperature to minimize thermal cycling
