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

[Mitsu™]

Lol pity my app doesn't run may I please have 700/1025 and 750/1025. I'll tell you how it goes guys I pray I survive lol

I've never experienced problems with Vram of 1000mhz but had problems with Core higher than 800+

I am about to test my OC on one of the games that were demanding for me aka Tomb Raider

This is pure madness !
I hope that you're fully prepared for what could potentially happen. Good luck

@Mitsu™ Using your latest builder, I get this error - any ideas? The original worked for me, when I delete and replace fresh no dice.

I'm trying 950/975 with Beta 8.

FYI, the slim models without NEC/Tokins have aluminum polymer caps with a quantifiable service life as well. IIRC they are 2000hr @105c rated, twice that of tokins. But it's not magic, they'll degrade eventually too. It's just a matter of time.

The 40nm RSX can usually clock higher, so that's a nice bonus, but there are other reliability considerations for 25xx and onward models. Namely, the wifi/blutooth module and a step-down converter that powers it have a tendency to fail. 20xx and 21xx models appear to immune from that particular issue.

The ripple is primarily generate by the switching frequency of the buck converters. which is between 500KHz and 1Mhz. That doesn't change much and the bulk filtering caps (NEC/TOKINs) are chosen to smooth out the gaps in the pulses (2-phase for RSX). The filter is attenuated (combined frequency response of the bulk filtering caps and MLCCs is calibrated) to reduce switch mode noise and harmonic frequencies of it. The amplitude of the ripple is what we're concerned with. Because if it trips the over (OVP) or under voltage drop-out (UVDO) protection you get a YLOD with SYSCON error A0801002.

The amplitude, or how much the voltage swings peak to peak (think of it as a big wave) is affected by load. So the higher the load, the higher the waves (more ripple). When you overclock you increase the ripple that much more. From our testing in terms of FPS, up to 33% more. But I still need to measure the ripple on an oscilloscope to quantify how much more voltage ripple it generates, as it's likely is not a proportional relationship to performance. Just cuz FPS increase 33% doesn't mean ripple does.

Now, the operational frequency of the core/VRAM might induce noise on the line that exceeds the bypass tuning of the filter and cause instability. If so, then yes a new filter would need to be devised to address the high frequency noise component.


I need to revisit this myself as I have a console that does the same thing when the power is unplugged from the wall, even though the clock battery has been replaced. I don't think it has to do with the polarity being backwards, but sometime the connector pulls out and I forget which way it goes back in without looking at a donor board. You won't have that issue on a slim with the button cell socket.

So are 2501B and 2501A Slims safe with OC when it comes to Nec tokens?

Strange, it works perfectly on my side.
Have you deleted the whole folder ?
Maybe try to delete the dedicated folder INSIDE the temp folder too ?

Yo some of these people really about to brick their PS3s trying anything above 1000 memory. My god what an utter waste of silicon winners. This breaks my heart. I've bought 4 slims already and none can do 750 bro. None. Let alone 800 850 or 900. Like this silicon winners are rare as all hell. I continue to seek them out. And no luck.

I had such error message. After setting Pathes(cfw out, ps3 keys) the issue was fixed

I think it's a little crazy too.
But there are warnings literally everywhere.
If they want to take that risk, it's up to them.

I rather buy that PS3 off if him before he does the damage.

Thanks bro. What we are doing is like in the car world, some pushing their cars to over 1000hp well this is similar, I am ready to risk lol.

Say before I try this, where can I get a Flasher for slim? Difference between e3 flasher and hardware flasher.

@Mitsu™ you are one of the few luckily ones lol

Just got out of bed lol here lies the moment of truth. Let me play crysis I'll get back to you.


Edit: No Artifacts so far. On my ps3 the culprit is core as I mentioned earlier 2504B I skipped the 1000 limit I am proud of myself lol

As the Chips warm up there is little artifacts. I am increasing my fan speed and see if it helps

I want to share my systems information
RSX code
Dump my lv1
All the necessary information.
How do I do that? I want to run the game couple of hours and going to switch to tomb raider again, also progress then share my information

Wow, the 1000MHz barrier is passed, this is insane !?

Congratulations, I'm in awe !

To dump LVL1 and SYSCON log, go to Evilnat options. There is a whole "extract" category.
Plug your USB key and go.

@Mitsu™ you are one of the few luckily ones lol

It seems x') And I'm using it on my potato phone through Winlator, so yeah, this is absurd. Thanks Windows I guess

Nice, but is there any difference in fps when you run at 950 mem? I think there is not much benefits when the cell is bottlenecking...

has anyone over clocked the 90nm cech a-b and c models? is there some "safe" limit that shouldnt be crossed, I was gonna try oc on my spare but its stuck on some update loop de loop trying to reinstall some update and it can't even handle it

Thank you! That was it :facepalm:

Dont even try this! The only way to oc fats is frankie mod

That's a good way to speed run a YLOD as 90nm models arent even safe at their stock clocks

This is the most interesting PS3 related project I've personally seen in a long time. I think someone should make a video comparison with a UE3 based game (you can easily tweak them to unlock framerate and show FPS on PS3). I doubt there will be a huge difference, but it would be interesting to see all the same.

Can you give us a little guide on that? Now that we are testing higher clocked overclocks, it would be great to unlock the framerates on UE3 games and see how they behave.

@Mitsu™
What is the impact of core and vram on the system? I am currently at 850/975. Is it necessary to try 900/975 again?

 

[LuanTeles]

I made a 850/1100 and is stable here (Crysis and GOW)

So i have not reached my memory limit yet, but my core is definitely 850 max otherwise random crashes (Crysis and GOW)

Maybe i'll jump to 1200 memory (100% overclock)


From 1000 to 1100 i got an increase of 4FPS, more than i'm getting with core increases

@Mitsu™ , just to let you know, I tested your latest mfw builder mod, after reading some comments of errors when building. it works fine for me like the others. built the insane 1000/1050 lol!
