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

[Zx6r]

Just pushed my cech-2004b ps3 slim to 650/800

And so far pretty stable and I can see fps gains and more responsiveness I wonder if I can push the 65nm gpu any more? Anyone with similar experience?

If you're lucky, you can try to push the VRAM a little further, up to 900MHz. But proceed with cautious, step by step.
As for the core, 700MHz is possible but it will depends on the health of your NEC Tokins. If they are too degraded, it may shutdown your PS3 when playing intensives games like Red Dead Redemption, Skyrim or Metal Gear Rising Revengeance. I suppose that it could also degrade them further.

I seen a youtuber with a same model of mine pushing gpu core to 700 and it started artifacts appearing on the screen so I guess that's a no go

As for vram does 900mhz benefit?

Well, except the shutdown issue, mine run without artifacts at all. It seems that each 20XX react differently.
650MHz core is already great, don't worry.

As for vram does 900mhz benefit?

Yes, and for all slims models, I'll say that 900MHz VRAM is the last interesting value in term of gains, before diminishing returns (but I need to work on this further).

VID HACKING UPDATE: 40nm Frank-E

Today I overclocked my CECH-E01 frankie. It has a New Old Stock 40nm RSX (CXD5301). At stock voltage, the highest stable I could achieve was 800/975, but I backed off to 800/900 for a safe margin. The best I could achieve stable with Vcore boost was 900/900 at 1.150v.

950/900 I couldn't make stable. At 1.3v it caused an A0801002...like the 2501a. Even in the frankie. Temps were climbing into the high 70s. Artifacting changed from interference/fuzziness, to green flashing tint and worse noise. It's definitely not stable, and I cranked the voltage this time. Temps rose to like 76c before I decided to crank the fan to 95%. And as the temps fell the artifacting calmed back down. Then it YLOD!

It was easy enough to back off the timings and revert to stock. No harm no foul. The frankie served it's duty well. I think I'll open it up tomorrow and see if I installed any tantalizers. IDR. If not, I will. Maybe that was the issue.

900 is still great for a BC PS3, and like you said there may be some ancient NEC TOKINS in there that could be causing the issue.

BTW, a little off topic but would you say that a CECHE is valuable to Frankenstein them and sell them off? I know they don't have EE+GS, only GS and EE is emulated, but apparently the compatibility is still high and the image quality is actually improved over the CECHA.

You hit the major points I usually mention. I like mine. If there is a ps2 game it doesn't play well, there's usually an HD remaster on PS3 anyway.

But people won't pay as much for them. And frankly dont want that model as much. If they are going to spend that much, they want an A model.

 

[DominicPS3]

Does anyone have a firmware with the overclock speed 650/850? Want to try overclocking my PS3 Slim 2001A

@Mitsu™ created basically any combination here https://app.mediafire.com/0uxvp5ismnjwm

Thank you for the confirmation, as a South African a CECHC/E is really my only choice for a BC PS3 since we get whatever Europe got.

 

[RIP-Felix]

you can import A00 from japan to frankie them

 

[Razmann4k]

True, let me qualify that statement: a CECHC/E is really my only choice for a BC PS3 that won't cost more than a brand new PS5 to own! Seriously, I checked and shipping will cost the same as the unit itself, and our customs are horrible unfortunately, some of my packages mysteriously disappeared at customs even though they successfully landed in the country...

Hi mitsu
my PS3 is CECH 2503B(CXD5300GGB)DateCode 1A
what is the safest maximum OverClocked cfw you suggest me?

This RSX model should do 850MHz core perfectly stable, maybe 900MHz. I wouldn't try 950MHz on core. Up to 1000MHz VRAM.
That said, it's pretty useless to OC it that high. After 700-750MHz core, performance gains get smaller and smaller.
So it's not worth the stress IMO.
If even at 700-750/900-950, a game run like $hit, then OCing the GPU can't save it, no matter how high you push it.

ok so can i install 600/850 in it?

 

[Mitsu™]

If it's enough for you, then yes

 

[fpoker102]

If it's enough for you, then yes

It won't damage my PS3, right?
600/850 is safest for my PS3

If it's enough for you, then yes

and i dump my LV1 memory of ps3 and search in it in hex editor 600/750 but it can't show me any other way to find rsx version in hex editor?

 

[cha0shacker]

Hypothetically, the GPU itself should have no issues at 1.240v assuming it's being powered with appropriate VRMs and filtering, right? Another forum member noted that the Curie architecture had plenty of cards run at 1.4V, so I'm assuming the Core is designed with that kind of voltage in mind?

These voltages were for 110nm and 90nm silicon, they don't apply to any other lithography even if the architecture is the same.

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.

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?
