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

Just search for you current clock speeds, eg; 600/750 then you'll find a whole string, just copy here and we can tell you.
When i install in my PS3 Evilnat 4.90 Overclocked 600/750 its shows this
rsx40 a01 600/750 vpe:ff shd:3f [AP0029328:0:2:13:18:1a:2:0:2][1f:0:a:0:1:0:1][1:1:0]
When i installed 4.90 CEX Evilnat its shows
this
rsx40 a01 500/650 vpe:ff shd:3f [AP0029328:0:2:13:18:1a:2:0:2][1f:0:a:0:1:0:1][1:1:0]
i think this values may be changed according to the firmware

you can import A00 from japan to frankie them
Believe it or not Felix, since speaking to you last I'm now in possession of a CECHA! It's a CECHA12, a Hong Kong region one which is basically identical to the Japanese revision. It has YLOD but I haven't read the syscon just yet. A game shop near me had this CECHA buried among the CECHC's and E's, I have no idea how it got here but I opened it up and it indeed has COK-001 board!

Additionally I bought 3 other non-BC fats that were not working. One of them boots up but has a red screen saying a serious error has occurred. Upon googling it, it may be the NOR that's been corrupted, anyone else experience this before?

===================================

So as expected it has the 3034 error (most likely dead 90nm RSX thanks to crap underfill), but that was years ago, it has since developed 2110 error that triggers before 3034 even has a chance to register anymore. 2110 is apparently an issue on the 5V line, I looked it up and F6001 on my board was indeed blown, now I could replace it but obviously it's very likely the short that caused it to blow is still there and will blow the new fuse too. So first I have to find the fault (probably a faulty IC), repair that, replace F6001, then try booting it to see if 3034 is back or if there's more errors in between.

Updated this post (diminishing returns) with some results for VRAM.

Great, so most people can get like 90% of the FPS boost from overclocking without winning the silicon lottery!
 
Thankyou Sir thankyou very much


Does the LV1 memory exactly tell you how much mhz it can supported?


Do you Have PS3 CECH 2503B DateCode 1A(CXD5300GGB) and what is the model number(with DateCode)of your ps3 which supports maximum mhz of OverClocked cfw?
no one knows how much OC your PS3 will support.
Start with the 650/750 OC then try 700 core, 750 core, 800 core, etc. until you get artifacts. then try increasing your memory. dont directly flash an 800 or 850 core fw.

Don't be lazy! No one can tell you what your GPU can safely do. You NEED to creep up on it one by one. And be warned the brick happens quick.

If this is too scarey, then stick to the 600/750. That usually works on most RSX. Maybe some 90s can't, but a 65 or 40nm can practically every time. Always some risk involved.
search "rsx" then. There will be many more hits, but you can find it that way too. You just need to know what your current clocks are. If it's stock then search "500/650" if you last applied the 600/750 OC, search that. If neither are present, you got a bad lv1 dump. dump it again and search again.
did you piggyback the 3 extra polymer caps on the underside of the pcb?

Exactly !
No need to hunt silicon winners, just buy a CFW-compatible 25XX, install 700/800-850 and enjoy !
Honestly, higher OC frequencies, except in the name of fun and curiosity, are pretty useless.

I've added some percentage to my post.

Summary in percentage :

• VRAM Overclocking (BioShock Infinite without V-Sync) :
500/650 to 500/700: +1.69%
500/700 to 500/750: +1.37%
500/750 to 500/800: +0.98%
500/800 to 500/850: +0.78%
500/850 to 500/900: +0.37%
500/900 to 500/950: +0.52%
500/950 to 500/1000: +0.52%

• Core Overclocking (Duck Sample test / Duck Engine) :
500/650 to 550/650: +8.37%
550/650 to 600/650: +8.64%
600/650 to 650/650: +6.28%
650/650 to 700/650: +5.51%
700/650 to 750/650: +4.48%
750/650 to 800/650: +2.86%
800/650 to 850/650: +1.74%

i think this values may be changed according to the firmware

The only thing that changes are the clock speeds in the rsx string.

@RIP-Felix is the right person to tell you the voltage by looking at your RSX string.

The only thing that changes is the core/vram frequency. the rest of that is stored in eFuses on the RSX itself and cannot be changed once they are blown at the factory.

EDIT: They can be overridden in SYSCON and/or LV1 however.

This is false. The duck test isn't a good benchmark. Cause all games behave differently to OC. 700/900 is a great OC for 25xx, but 900/1000 has huge gains accross actual games, not just a duck test. Engines behave differently to frequencies. So you still want to hope for silicon winners. Even 2 to 3 extra FPS is huge!!! For games that target 30 FPS, which is most PS3 games. But sadly after this our biggest bottleneck is the trash cpu and it's low 3.2ghz

I checked it with several games and what the duck test gives is confirmed :)

Look at GT6 1080p, the difference between 700/900 and 800/1000.
One example among others.
IMG_20240617_214350.jpg

Speaking of games that aim for 30 FPS, 700/800-850 is more than enough for them.
Again, if despite that a game run badly, it's not a GPU issue. It's either a CPU-bottlenecked title or it just suffer from $hitty optimization.
So I confirm and sign, buy a CFW-COMPATIBLE 25XX no matter its RSX revision, and enjoy.
700/800-850 is more than enough for most of the games, with an insignificant impact on lifespan. After that, you'll still have gains, but diminishing returns.
So, it's useless to stress the hardware further.
The GPU alone can't save everything !
I'm not the only one saying this btw, @Ketxxx posted about it several times.

I admit that I was a bit doubtful at first, and that's even why I did tests myself to see, and he is right.

For further meaningful improvements, what we need is a CPU OC, I agree.

If you have concrete examples, results, to prove that mine are false, go ahead. I have no trouble admitting that I am wrong when that is the case.
On the contrary, it will help our research.

Hello!
I recently upgraded from the 2001A Slim to the 2501A Slim for best performance and reliability. I'm interested in putting 4.91 EVILNAT BETA 8 OC firmware as it's publicly available but I'm not sure how to set the MHz I desire and not sure if someone has suggestions.

I looked in this forum a few days ago and someone mentioned that for the CXD5300A1GB RSX that I have in my 2501A unit can do 700/900 good. Not sure if this is a good combination or is there a better combo for my RSX or if I should go with that combo!

If someone knows how to put the file together so that it's ready to go in my console or help out adjusting the appropriate MHz from someone I would really appreciate it! :-)
 
Once again, thank you very much @Mitsu™ for the easy access to the OC firmwares!

I have posted a comparison benchmark YouTube video on Gran Turismo 5 1080p between 500/650 and 700/850 on a launch CECH-2001A Slim with less than 11 days of runtime. This overclock should be a realistic number for most PS3 consoles (other than 90nm RSXs), before encountering diminishing returns.

Looks like I can't post the video just yet. :apathy:
 
I'll show you some more stats later, but I can confirm @Mitsu™'s results.
If I have the 3034 error, do you still recommend removing blu-ray drive and putting pressure on the RSX clamp to check if it's BGA? If I kill the chip even more, it's not the end of the world since it's already giving me 3034, but I'd rather not do it until you confirm this is still something you recommend trying (I read a forum post of yours from 2021 mentioning this, and I know how much has changed since then in terms of YLOD knowledge)


does the game runtime on the fps overlay works ????

I'm trying to activate it but it wont show up on the game. any idea how to make it work
While playing the game, press the PS button to bring up the quick XMB menu, wait till the icons show up, then click in both analog sticks and wait till the overlay pops up, then press the PS button again to return to the game and the overlay should still be there.
