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

Hello, I'm getting an error on my computer and I can't install it. Can you add these clock speeds as Beta 9? I'll be glad if you do.
600/750 650/750
600/800 650/800
600/825 650/825
600/850 650/850
600/875 650/875
600/900 650/900
 
I would also think so, but I keep the temperature at 65 degrees, and before updating the firmware to higher frequencies, I deliberately lowered the fan speed and played at 76 degrees and everything worked stably, after I raised the frequency of the GPU Sony it crashed and produced artifacts. I returned the previous firmware back, after this something clearly happened and the frequency, which was completely stable, became unstable, in addition to crystal degradation, there are also suspicions that something happened to the power supply and it produces an unstable voltage, at the moment there are no other ideas , why did this happen.

Replacing the power supply might help. But honestly the chip couldn't have degraded like that. I own 7 and tested them all at various temps and frequencies and never have I had that issue. Do 800/950. That should be fully stable.
 
Do you happen to know what the purpose of the variable resistors in the Sony power supply is, maybe they change some voltage, I just didn't find information about these variable resistors in the power supply on the Internet.

I have no what you are talking about dawg. If you can't OC stable at 850 that's that. Go back to 800 bro.

i want know if ps3 slim in europe have or not the good hw for oc

Yes, but since we have to deal with these date codes, this is like a double lottery. We can't know the exact month of manufacture and same for the chip in it.
0D or 1A are your best chances (1A are the best).

At the request of Mitsu, just wanted to pop in here and post my results from overclocking my 2502B (which has an apparently lesser known RSX revision of CXD5300DGB).

Console seems happy at 700/1000 when playing Crysis (haven't tested anything else yet). Can't push the core any higher. Even going to 750 causes the white flickering textures.

Seems like a bit of a weird lower core and higher memory mix with the silicon lottery. Not that I'm complaining though, still a good OC.

@RIP-Felix , this RSX model isn't on PSDevWiki ! :0
This is a new revision !

Yeah those date codes make it so hard for people to bin high OC models.
 
I own a PS3 Slim CECH-2504B with a 1A date code and I have been running my system on 750MHz / 1000MHz for about a month without any graphical artifact issues, or game crashes. I wanted to push my PS3 system up to 800MHz core with 950MHz memory, and there starts the graphical artifact issues which happens almost instantly after the system update but it wasn't a big issue. However, trying 850MHz core with 900MHz showed big red artifacts on the screen the millisecond I booted into my XMB, and because of my quick reactions, I immediately unplugged the PS3 cable. Why is it that my PS3 is not handling 800MHz on core very well? Many other CECH-2504 models can possibly overclock even more than that, but mine's having issues already at 800MHz on core. Why?
 
Ok, so I had a little time to start some testing and working things out, I ended up starting with Dead Space just because that's what I happen to be playing. The game is a fairly middle of the pack one in terms of optimisation, runs ok for the most part with certain areas causing the frame rate to dip to 20FPS or below. I ended up using the room toward the end of chapter 3 where you have to manually ignite the engine for a testing ground as once you manually start the engine and you deal with the surprise mob if you stand exactly in the doorway and aim at the computer in the center of the room that, for whatever reason, ordinarily causes the frame rate to tank to 20FPS or below. Dead Space I've found to be a little bandwidth limited with only modest improvements between 650-750MHz (around 5FPS) but frame rate and frame pacing did quite notably even out. The big improvement came when nudging up the GPU frequency, a mere 50MHz uptick saw the problem test area jumping from 20FPS, well, 19.96 to be exact, to 29.965. I have a capture card so will be getting some footage for OC results when I'm done with testing and working other factors out like fillrate and bandwidth improvements but so far my initial thoughts are on point; 650\800 should be the sweet spot for a smooth experience in most titles except for the ones that are choked by the CPU in which case it really won't matter what clocks the GPU has you'll see little to no improvement. Temperatures are also well in check @ 550\750, about 63c after several hours under load with the fan manually set to 40%, we don't want to be ramping the fan up much more than that lest PS3s the world over start sounding like jet engines.

As a last reminder; while it's temping to clock the snot out of the GPU remember that most games on PS3 were designed for 30FPS so any performance that would allow a higher frame rate is totally wasted and any titles that did aim for 60FPS 650\800 clocks is going to get you a much better experience anyway if you need to push higher than 650\800 the game has a lot more problems than just a bottlenecked under performing GPU. It's not likely your PS3 will live very long either if you push it too hard temperatures are a factor for the PS3 due to the terrible thermal design.

Because date codes are random months you'll never know. And silicon lottery is a big factor. But most importantly you don't know what month exactly it was manufactured. December and January are the most Overclocking capable chips. Mostly January. Here in the US it's easier for me to get my hands on high OC units because we get exact month. All my 7 PS3 slim January's do 850 and 900 and even 950 core. With 975 memory and 2 doing 1000. Memory is also silicon lottery.

I had another look on the Wiki and it actually does seem to have its own page (can't post link because forum newbie), It's just not in the RSX table for some reason.

You're right, I didn't see it !

Because date codes aren't guarantees regarding the chip you'll get. Even the month of manufacture isn't an absolute guaranty.

The limits of your PS3 depends on your RSX model. Even in the 25XX series, you can have 4 different revisions :

• CXD5300A1GB : This one can do 700 on core easily, 750 if you're lucky. As for memory (VRAM), 900 or 925. Maybe 950 at best.

• CXD5300CGB : 800 on core stable, 850 freeze after some time in game. Up to 1000MHz on memory if you're lucky (stay cautious).

• CXD5300DGB : We don't know it well, the only report say 700/1000 stable max.

• CXD5300GGB : The greatest overclockers, 850 or 900 on core. 950 is EXTREMELY rare. Up to 1000MHz on memory.

Of course, there are always exceptions due to the silicon lottery.

While later date codes give you more chances to get a good chip, this is still a lottery (a triple lottery in fact. Month ? + Chip revision ? + Silicon lottery ?).

AMEN BROTHER!!:D I hope people that come here read this exact comment. This is a perfect Info dump. As for me. I'm starting to sell the high OC models now. I'll keep sourcing them and selling them.
