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

I bought my Cech 2501b console, it is currently cracked with cfw 4.91 evilnat. Now, if I install the overclocked pup file, is there any need for operations via the internet browser, etc.? Can I just install the pup file and continue or do I have to do the cracking process all over again?
No, simply install like normal.
 
GTHD basically crashes as soon as you move past the stock clocks or have an overlay on. That's not on the GPU though. The game does a weird CPU/GPU sync that gets fucked as soon a you move past stock. Thats one of the few compatibilty problems that come with playing with clocks.

This has been driving me mad. Crysis (mission 4 beginning looping) is stable for 10 hours, but GTHD crashes with the following scenario:

Wait for replay to play by idling on menu, press start to quit replay then when back at menu press PS button = sometimes freeze.

It seems from my testing the higher the core clock, the more likely it is to happen. I just got it to crash at 550.
Can you elaborate on the "weird CPU/GPU sync that gets fucked as soon a you move past stock"

It's only rare specific games that have this issue. Very very very rare. And that has to due with the bad code in the engine. But this is something that isn't an issue accross 99.9 % of PS3 library. It is a slight trade off. I can only guess a Max handful of games have issues like this. I've tested over 100 games, yeah I know, no life. But yeah no such issues. But there's gonna be some games that get panics due to Overclock. All my favorite games and types of games work perfectly.
 
hi guys i want to report the following, im using an OC version on my 2101B under 700/850 CEX 4.91 beta 9, i was able to play some of the games very stable with no artifacts or anything wrong, my temps are under 64C on both rsx and cpu at 40% fan speed and my room temperature can be between 19c maybe a little lower sometimes or hotter up to 22c, for more than 2 hours of gameplay i dont see that the temps going beyond that if i use CEX CFW no PEX, but if i install PEX under the same OC frequencies, my temps ussually can go up to 69C, especially on sniper elite 3 that one is a game that it can carry my ps3 temps up to 69C or even more depending the time that i play it, my question is, do you why that it can happen, maybe PEX does more things into the system to make it work a little more? i remember that sometime ago i used to have rebug rex but when my console went to be into dex at some point everything was going slow, it seemed to occupy more ram usage than CEX only and also i used to have more crashes on the games frequently, so im wondering if maybe when the console is under PEX will make a huge difference between CEX, on my end it seems to be the case but i want to ask you guys before going into any conclusions

Afaik all you need to do is install the pup file with the overclock, at least that's what I did, and my console is still working thankfully
 
Yeah, I have the same feeling. This is something else probably. I was blaming the fan (for some reason) because with high speed I mean >75%. The more I get close to 95% of fan speed, the more often the console seems to crash. I have also checked the syscon error log over and over again but nothing I found makes sense. What's interesting is that I once managed to force the console on despite the absent red light....and I was met with a flurry of scary messages about corruptions everywhere, and the system was unable to recover itself (It would start to boot XMB and freeze). This made me start suspecting that the HDD was dying...but...

Unplugging and replugging fixed everything (???).

That said, given your interest in this problem (and my thirst for a solution, as well as the possibility of increasing my OC), I'll proceed to give the data you asked for.

First and foremost, I am on Evilnat 4.89 with Cobra 8.4 and the 600/750 config that comes with it. I'm not on latest because I didn't yet find the courage to install a newer firmware with a higher OC (Despite me having one of the generally luckiest models). Since I have no HW flasher, if the OC is a tad overboard, it's over, and I absolutely love this console and don't wanna lose it.

Either way...

Days of usage: 127 (3,033 on, 2,764(269) off).
Note: I treat this console like a queen. Thermal paste is swapped, I only use it when necessary, and I keep the temps below 65°C no matter what.

Recent Syscon Log: It's made mostly of 1601 and 1701 errors (0xA0801601/1701), and only one 1200 (Which I can recall, since I willingly caused it many years ago to check when the console would shutdown lol). What's interesting is that there are a handful of 2022 errors.

Fan Speed: This occurs at any speed that is above 70%. It becomes very prominent at max fan speed.

Stock Frequencies: I don't recall having this issue at stock frequencies. But back then I was on a different and older CFW (Ferrox, Cobra 8.2), and I was also on an older release of Webman. Honestly I noticed that this problem really started to exist when I updated Webman. That app tends to crash my PS3 a lot. Sometimes I can't open the Webman setup without the console freezing.
I had a 1601 error once on my 2504, I was messing with some settings in WebManMod, trying to dump huh... something (I don't remember x) ) and it instantly made the console shutdown (with no LED too). Never had this issue again since.
With such a low runtime, I think your PS3 is fine.
A hardware issue would be unfortunate.
IIRC, too high fan speeds may results in huge slowdowns and/or crashes. Especially true the more you're approaching 100%, but 70% seems already pretty high to me.
Do you really need to set the fan speed to 70% to keep the temps below 65°C ?
I mean, 45% should be more than enough. I don't know what temperature you have in your gaming room, but still.
Also, don't worry, a slim easily support 70°C. Above 75°C in the long run might cause issues, but 70°C is fine :encouragement:

The 2022 errors aren't worrying.
Those are mostly indicating that you're playing PS2 games :P

I recommend you to try to lower your fan speed (if possible) and try again :encouragement:

I don't need to keep fan speed that high to have low enough temps, but since it's summer and my room temp is in the mid 30s, idle temperatures are high on my PS3, despite the recently swapped thermal paste. Since I was aware that at 75 degrees, both Cell and RSX start to suffer, I was trying to keep fan speed high to keep them as far away from that temperature as possible to max out longevity and stability (I saw some people claim and prove that a lower temperature can help stabilize unstable overclocks and allow them to revert to safe settings). I don't understand how a fan can cause an entire system to shutdown with no LED. PS3 mystery. Furthermore I'm still considering the possibility of installing a newer Evilnat with a higher OC, but I've seen that VRAM can be very unforgiving and quickly brick the console. Thank you very much for your interest in this matter by the way.

Not sure but maybe the fan is drawing too much power, leading to instabilities.

Yeah, be careful. Without knowing your exact RSX revision, you really shouldn't OC more than 700/850.
It's an OC that any 25XX will support without issues and it represents most of the gains, before encountering significant diminishing returns.

That wouldn't be bad. I'm not looking for record shattering OCs. Just something that can make Gran Turismo 6 run decently. You got any idea where I could get an Evilnat with that clock config? Do I have to bake it myself? I think I'd be insanely unlucky if my console bricked with 700/850.

It won't get bricked, we've never seen a 25XX unable to support this OC.

Alright. I'll be updating with the 700/850 Beta 9 4.91 PUP. Currently I am on Evilnat 4.89. I can just update as normal right?

I have successfully updated to 4.91 with 700/850. Thank you very much Mitsu for your help. I will now do some testing to verify stability and whatnot.

I am curious to know, though, since PS3s are wildly different across models, do you know what are the average overclock figures (and higher average) for each revision of the RSX? I'd imagine early fat models can't even handle 550? It's also interesting to think about what the Super Slims could do if they are ever unlocked. They go from the 40nm RSX in the latest Slims, to 28nm. That's a huge jump. I'd imagine that Super Slim would be able to average 850-950MHz for GPU. Very intriguing to think about.

There are some general "rules", even if finding out your console's limits yourself is always better and somewhat fun :
• Don't OC a FAT more than 600/750. Personally, I wouldn't OC a 90nm RSX at all.
• For a 20XX slim, 650/800-850 is the maximum you should attempt. 700MHz core is likely to cause issues ( due to the NEC/Tokins capacitors.
Note that if your NEC/Tokins are particularly degraded, even 600MHz core might be too much.
• For a 21XX, 700/850-900 is possible, 650/850 is guaranteed.
• Starting from the 25XX series, we're talking about RSX revisions because there are 4 known models with different limits.
- "CXD5300A1GB" : Basically the same chip found in a 21XX, so 700/900
- "CXD5300CGB" : 800/975 is possible, even 850/1000 if you manage to keep your temps below 70°C (or it might freeze in some demanding games).
- "CXD5300DGB" : Okay, this one is a bit mysterious. We don't have many reports about it, it seems to perform like a "A1GB".
- "CXD5300GGB" : If you like big numbers, this one if for you ! The latest RSX revision you can find in a CFW-compatible PS3. 850MHz core minimum guaranteed, 1000MHz VRAM should be easy for it too.
900MHz core is possible, 950MHz too but it's super rare.

That's all !

Now about the SuperSlims... I'm curious too :p
Even if one day we'd be able to fully jailbreak them, maybe it won't be as incredible as one could think. It's a possibility, sure, but it all depends on Sony !
These models are cool, but they're also super cheap in many ways since Sony went into "money saving mode : MAX", so... I don't know about their potential.

Also, I recommend you to check these posts about diminishing returns :)

finally my ssd, termal paste and t8 torx screwdriver arrived today.
this is my lovely "CXD5300AGB" from slim 2106A.(any info or experience with this one?)
i will start with 650/850
every advice and suggestion is very very welcomed.
let's see what's possible!

This RSX revision is the only one findable in a 21XX.
You can try up to 700MHz core and 900MHz VRAM max and load a demanding game like Crysis. Proceed step by step.
700/900 isn't guaranteed to be fully stable on this model (no artifacts, etc...), but it won't brick it either. So if you notice anything wrong, just reinstall the previous OC.

Is there any way to figure out the RSX revision in software? Or do I have to disassemble the console?

Also, about Super Slims being cheap, yeah, you're very right. A friend of mine owns the 500GB Super Slim. When spinning the fan to 100%, his console legit starts vibrating so much that the Hard Drive ceases functioning properly. He had to reset his Webman settings to boot again.

Either way I'd argue that Super Slim would have huge potential, despite all the cost saving measures. The 28nm RSX is an extremely small chip. It likely draws very little power, even compared to the 40nm RSX. We'd most likely be seeing 1GHz RSX on a fairly regular basis. In essence, PS3 Pro. 2x the theoretical GPU performance for the luckiest RSX users (And Super Slim, theoretically).

The only way to know your RSX revision will be to open the console and check the RSX's IHS before applying thermal paste, unfortunately :friendly wink:

Someone (Nascar) managed to OC a PS3 to 1000/1000 with a voltmod. An interesting experiment but honestly the gains aren't spectacular. It's just confirming less and less significant gains the more you're increasing frequencies (while the stress put on the hardware is still going crescendo. Heat, electromigration, etc...).
So, while it'd be interesting to see how much a 28nm can support without voltmod, it probably won't do wonders in-game (and that's without talking about the huge bottleneck the CELL is).
 
Friends, I bought the playstation, today when I was turning it on there was a piece of paper under it, when I took out the device to get it, it immediately shut down. I tried the same movement, tried to put it in a slightly upright position, and it immediately closed. Is this a problem? Additionally, the yellow-green light flashes when it is turned on. There is absolutely no problem in working, I only experience this problem when I lift it off the ground and put it in an upright position. (500GB HDD no SSD)
 
I had a 1601 error once on my 2504, I was messing with some settings in WebManMod, trying to dump huh... something (I don't remember x) ) and it instantly made the console shutdown (with no LED too). Never had this issue again since.

great thanks a lot Mitsu lets hope that maybe it can make a difference on the OC tests that you will make to check on that one
 
This has been driving me mad. Crysis (mission 4 beginning looping) is stable for 10 hours, but GTHD crashes with the following scenario:

Wait for replay to play by idling on menu, press start to quit replay then when back at menu press PS button = sometimes freeze.

It seems from my testing the higher the core clock, the more likely it is to happen. I just got it to crash at 550.
Can you elaborate on the "weird CPU/GPU sync that gets fucked as soon a you move past stock"
I can try, it's not that easy to explain.
The way the work distribution in all GT games on PS3 is done is in lock step mode.
Basically a certain amount of clock cycles on the GPU/CPU is counted to measure when the SPEs have to do a certain task for the game that then has to be processed by the GPU and then output to the screen.

At 500MHz the SPE has basically time for 6 cycles to do its work for the RSX (Because the SPEs run at 3200MHz). When you start to OC to to 550MHz or higher suddenly only 5 cycles fit and the GPU stalls hard because it doesn't get the information in time anymore that it is coded to wait for.
That's also why it isn't a complete crash, only that the system is very very unbearably slow.

Later GT games thankfully used additional measures to ensure synchronization.

GTHD is just an early title which are usually only very crudely adapted to the target hardware. And it's also an example why later console versions don't just change their parts for faster ones or run the original ones at a higher clock. It will lead to compatibility problems which a console manufacturer will want to avoid at all costs. Nobody wants a second PS2 situation.
 
This RSX revision is the only one findable in a 21XX.
You can try up to 700MHz core and 900MHz VRAM max and load a demanding game like Crysis. Proceed step by step.
700/900 isn't guaranteed to be fully stable on this model (no artifacts, etc...), but it won't brick it either. So if you notice anything wrong, just reinstall the previous OC.
Sir Mitsu, I am currently using 700 850 and it is very stable. I tested it for a long time, thank you for everything. My question now is, I want to know the limits. However, if I increase it by 50, 50, 50, for example, now it is 700, 750, and then 800, 900, will the device be bricked? Or can I recover it with minor corruption and return to the old file?
