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

[Mitsu™]

No it doesn't. At all. Stop. I did a 5 hour test with 500/650 and then did 5 hours with 950/1000 in crysis HD. Temps were identical. The amount of cap is crazy. I also did an XMB temp test. And again. Identical. Nothing changed at all.

Dude you're playing with an uncapped framerate! That increases the stress even on pc! When a FPS is capped to 60 or 30 the temps don't rise. Forcing more frames with an uncapped setting like the bioshocks the frames go higher so the load is higher! So higher temps, and the OC allows for higher frames so temps can rise! No other game on PS3 has a framerate that goes above 60 like bioshock! This is a terrible! Example. See you don't know what you are talking about. Now how about you test a game that targets only 60 and or 30 and try it there. How about also try the xmb. You'll get identical temps. Bioshock is a rare anomaly that lets the game run at high framerates. By the way. Also standing there where not much is happening will literally almost never happen during the entirety of the game. This game can never hold a 60 FPS. It averages 38 to high 40s maybe. So those temps will plummet. If OC means higher temps, it would be higher on all games and xmb as well. Notice how crysis is a much more demanding game than bioshock will ever be, yet because it's capped to 30, temps aren't higher compared to OC. Hell even a cap of 60 temps are higher than caps of 30 naturally because more frames are pushed. This applies to stock as well. It's how it is on pc too. If I cap a game on pc to 30 FPS my temps plummet hard. And the more I keep increasing the cap. 40 to 50 to 60 to 70 to 80 to 90 all the way up to 165hz, the temps continue rising. You're grasping at straws. Besides was this convo over? And notice how you're pushing an extra 33 or so more frames? Yeah. No sh!t the temps would go up. If you don't understand how loads work or how GPUs work, just say that. Real funny how out of all the games you choose this one. Which is funnier.

Even on XMB, there is some more degrees btw.

2c on sonic could be Margin of error. Ambient temps. Or load depending on the direction you are looking and rendering. The metal gear, is a measly 2 or 3c and only cause it's pushing the 60 mark. So yes temps can go up there. But games that are capped to 30 or 60 won't increase at all. The OC doesn't increase temps, it's the frames it pushes if the gains are much higher. And again, 2 to 3 is Margin of error. Ambient temps need to remain the same. And test needs to be done identical to the last. Plus time is a factor. Longevity of the test. I've done weeks of testing. Across all my PS3s. Making sure there wasn't any errors in my testing so I can say, Overclocking does no real damage or temp increases. Higher pushed frames is a higher load. Which the stock underclocked chips didn't do. A 2c to 3c on average temp increase depending on the game that has higher framerate target wouldn't do a damn thing to the PS3s longevity. Most games on PS3 are all capped to 30. More than anything, an increase in resolution would make the temps go higher. But also higher framerates rendered puts more stress on uncapped games. Outside of bioshock, no other game can break the 60 mark. And I'm guessing that was an error on 2ks part by not capping the frames to 60.

Thanks guys my PS3 Slim datacode 0D is running at a stable 800/950, i dont want to risk and push it over since i dont have a hardware flasher. Im really happy that finally i can run games smoothly. I cant even imagine what a ps3 super slim cech 43xxx 28nm can do if it gets someday to be overclocked.

DateCode OD and what is the model number of your ps3 bro?

 

[fpoker102]

Ok, this is pure sorcery.
With 850MHz core being stable only under condition (temperature), I was afraid it wouldn't even boot.
And yet...

Obviously, I need to test it in game and I'm almost 100% sure that it won't be stable.
This is impossible.

EDIT : Okay, as I thought, it freeze in Crysis after less than 5 minutes. And it was still around 45°C. Zero artifacts though.

(Still my 2504A 0D/CXD5300CGB)

I know, I really played with fire trying this.
Honestly, don't do this. It's super dangerous.

so what is the highest maximum stable OverClocked cFw fir 2504A

No matter the subject, I REALLY need to stop trying to debate with you. It's just a waste of time.
Really, I appreciate you, but man, you're so pedantic and full of yourself...
It's like talking to a wall.
So let's say that you hold the universal truth, you're the greatest (and only ?) expert here, and that's it. GG.
Agree to disagree.

so what is the highest maximum stable OverClocked cFw fir 2504A

It depends on your RSX revision. But anyway, 700/850 is completely safe and enough for most of the games.

Once again. Thanks for the concession with no real rebuttal.

700/900 is your 100% assured OC fully stable. But you won't know till you test 50 core At time. Do not touch the memory just yet. Make sure to find your fully stable highest core. Then test memory 25 at a time. Do not attempt 1000 memory. That could give you a brick. I'd say 950 if fully stable, is a great OC. But this is something you test thoroughly and with patience.

 

[Mitsu™]

I'm choosing to step away from this discussion, not because of a lack of rebuttal, but because continuing it seems totally unproductive.
You'll maintain your positions no matter what, so it's an utter waste of time.
I'd rather move on, it's wiser.
In any case, it's up to everyone to form their own opinion now.

 

[fpoker102]

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

brother my ps3 is CECH 2503B 1A so 700/900 will support my ps3?

 

[Mitsu™]

It will support it, 100% guaranteed.
Once again, 850MHz VRAM is enough, but if you prefer 900MHz and feel comfortable with it, it's your choice and your PS3 after all

I've been tracking the RSX overclock development and lurked here since the beginning but sorry to say I felt the need to step in this one just so everyone is on the same page. While it's true freq doesn't kill chips, but in all chip circuitry, power increases linearly to frequency.

P ∝ CV²f

With more power comes more heat generation.

On my 700/900 PS3 CECH-2004B (45nm/40nm) alone I have seen instances where the fan dB goes up a bit and RSX reaching equal temps to Cell which had never happen to me before. I run the stock Syscon so they usually settle at 72°C and only ramp up fan as needed. Mitsu's Bioshock video already shows 5°C change over stock

Your temps might not change in OSD due to Webman curve but remind you that fan speeds in Webman are not really that accurate and might not reflect slight rpm ramp ups.

Another factor to take in is the fact that most PS3 games have capped frames. A 700Mhz GPU hitting the 30fps Vsync is going to have a lower effective utilization (i.e % time working in a period) vs a 500MHz GPU barely holding the 30fps frame target. Bioshock Infinite or Gran Turismo 6 in SSR5 track main straight is a better test candidate than most games as these scenarios (Bioshock is uncapped, GT6 is 1440x1080 with many overdraws in SSR5) actually hammer the GPU subcomponents rather than SPE/bandwidth heavy operations in Crysis.

Great intervention

DateCode OD and what is the model number of your ps3 bro?

It's a CECH-2503c datacode 0D, idk which RSX model it has but i think it's either a CGB or a GGB because its running at a stable 800/950 since i commented.

Greatest Advice Brother Mitsu and its working tell me what is the highest maximum OverClocked limit of ps3 2503B 1A as per your experience for example like 850/950 or something else?if i Install 800/900 will work in my ps3?

As I said, without knowing your RSX revision (like "CXD5300CGB" for example.), it's impossible to tell unfortunately.
You can only see this before applying thermal paste on the GPU's IHS.

My PS3 CECH 2503B 1A GPUs IHS

Nice !
So, 850-900 MHz on core are possible (950MHz is unlikely and therefore risky). Up to 1000MHz should be possible, but it's always a dangerous value to approach.
That said, these are the limits of your RSX revision. It doesn't mean that you should obligatory go for this. Once again, it's your console
Proceed carefully and test thoroughly if you choose to try these frequencies.

 

[Tanzu15]

700/900 for sure. Memory gives more performance. Then test going up little by little. Until you find your highest stable. With memory, go up 25 at a time. But first start from 700/900 and start going up with core. And test crysis HD. Of after an hour you don't crash or see artifacts. You're good. Then you can test an extra 50 until you lose stability. Then crank it back 50.

Test 800/900 first, and if it's perfectly stable, then try 850. It's better to be safe than sorry.

 

[fpoker102]

700/900 for sure. Memory gives more performance. Then test going up little by little. Until you find your highest stable. With memory, go up 25 at a time.

Can use games red dead redemption or the last of us instead of crysis HD?
