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

You can pretty safely start at 600/750. M4jor and Proto did alot of testing to arrive at that OC, trying to fine one that was "safe" for all consoles. Now, that's mainly to be safe for 90nm consoles that can't, and arguably shouldn't be OC'd very high. A 65 or 40nm should easily handle 650 core.

Start with core increases of 50MHz at a time. At the first sign of instability, back off. Then start increasing VRAM. But be careful, I was 100% stable at 950MHz, then nearly couldnt recover from 975! It went from perfectly fine to nearlu fully bricked in 25MHz. The VRAM increases can give no warning.

it always says :
Error running script: !!ERROR!!: FAILED TO IMPORT SELF-SCE HEADERS FROM FILE: lv1.self

You need to generate the lv1 after downloading MFW Builder. In the readme it explains. There is a nice batch file in the root directory you can run which will guide you through the creation process. Run it, type in the FW updates and it'll generate them automatically. I'd reccomend deleating your current installation and temporary folder, then DL'ing fresh from Haxxxen's github repo.

ok ill start at 600/750 then go to 650/750 then 700/750 and so on till i get artifacts then move on to vram. i dont really know what to do with vram if it gives no warning :/ also whats the best game to test for artifacts? is there any way to recover after a brick like a recovery tool or something. incase the worst happens
 
my little brother accidentally flash cfw in FSM and then it shows rsod i change the harddrive but it shutdown itself and when i try to use e3 flasher on it ps3 shutdown itself?any suggestions

You'll have to hope for the best and test multiple games in different scenarios to try and find differences. Which means you need a test spot in each game and know what's out of place. TLOU, Uncharted 2, Crysis 3 are my go to games. People here like Crysis HD.

I'd say if you can get to 900VRAM that's far enough. 950 is like 0.5FPS better, but brick territory.

If you freeze and cant update, try cooling the console as much as possable. Box fan, cold garage, and update in safe mode. That might allow you enough time to complete the update. I used SYSCON UART to force the fan to 100% when I bricked. That made it just stable enough to update back to a safe OC.

Otherwise, only a hardware flasher will work.
 
Like felix said try cooling down your console as much as possible so is gonna let you update to a more safer oc personally DON'T even think Putting it on a freezer or something like that you'll damage it try cooling it with a more natural air like the air condition tip..if you can take the top of and let the extra cool air flow inside is better is like water cooling to GPU 29C/RSX 29C iam 100% this is gonna work because i stable my overclock to 800/900 not (compatible model)with this method
thanks for the suggestion bro but i m not asking about the RSX?

Same model as mine you can do 700/950 no problem! Try 750/950 after stressing the hardware with a game like crysis/sonic unleashed wherehog stages only) god of war last of us metal gear solid those kinda of game if you got no artifacts or freezing while playing for 30 minutes to 1 hour then is stable and you can keep it if you get any artifacting try increasing the fan speed to 50%-60% MAX more each time you se weird artifacts in some a certain stage of the game and look if it gets fixed just to se if your console is temperature guarantee but is purely 700/950 900 vram if unlucky

If your PS3 is artifacting, you shouldn't raise the fan speed but step back to lower frequencies.
It means that you're pushing your RSX too hard.
A good and safe OC must be 100% stable at any temperature.
Btw, if a PS3 can "only" do 700/900, that's not a big deal at all (once again → diminishing returns).
In fact, even 700/800-850 is enough.
This should be a standard and relatively safe OC for all 25XX models.
After that, you're just stressing your console for "crumbs".

Actually you're getting 000,23 more fps☝️

great! ill just step back if i get artifacts but glad to know i should be able to get a nice oc :)

theres no 750/750 or 800/750 in the packs :/

BTW VRAM instability tends to cause freezing. If you're lucky to see it, it can cause pinpricks of light, speckles.

So likely, your VRAM was fine at 850. It was the core at 700MHz it didnt like.
Yes there was light speckles and rainbow lights too followed with artifacts
