Red Star Rising about half way through the mission.

do game resolution related cvars work?

Hey everyone! Been lurking and following this thread for a while and decided it's finally time to chime in with my results. First off, thank you so much Mitsu for posting a ton of OC builds!

Slim 2101A with "AGB" RSX (I think all 21xxs have the AGB chip?) - 700/900. 750 core has the XMB artifacting like crazy, and 925 on the VRAM starts artifacting a little in Crysis once the system warms up. Still a healthy boost on a console I've had kicking around for a while!

Over the weekend I found a cheap 2501A dated September 2010, and boy was I excited! Cleaned up and repasted, found it has the A1GB RSX. Sadly, this one is also stuck at 700/900. 750 artifacts less in the XMB than my 2101, but it still does it. 925 VRAM seemed ok in Crysis, but 950 froze the system after about 10-15 minutes and I'd rather not ride it that close to the line. Was really hoping to get at little more out of this one

Yup that's the case for practically all earlier 40nm chips. The luckiest chips are in December and January. Anything behind that is just 700 core fodder.

I wanna try a 750 650 - up on both as the firmware's I have loaded at the moment some work such as 750 - 650 but others just report the same stock clocks as OC Evilnat that's the base firmware at the time think it was beta 8 before I tried yesterday at beta 9 and got the same results (To be fair I just think my Samsung USB is dying or the nand is going bad on it) so I'm going to order a new USB on amazon at the moment though any recommended OC's will be fine I do wanna test as many as possible without breaking this console as I'm hoping the other models in my loft are not the 2003b version's as those are common in the UK it's suprisingly hard to get hold of a 25xx model of slim here :/ I've already spent like £200 on more consoles as well as £150 on PS4 that is version 11 (Sorry I'm not converting the amount).

I don't want to go insane at the moment until I confirm I have another model that can also push higher clocks as well as actually show me it's reporting the right speeds for a change again only on some firmware's it does this.

I hope I get lucky to be able to reach as high as that

Thanks in advanced!

Try this. This is not an excessive overclock and something every 25XX (even the earliest) should handle easily.

It seems that CXD5300A1GB RSX can't OC high.
This is the earliest version among the 25XX series and is basically the same (or a minor revision) as CXD5300AGB (21XX series) which can barely do 700MHz on core.
You should search a December 2010 one or a January 2011, you will have more chances to find a "high potential" model.
(700/900 is already great btw, but I understand your frustration.)

I've been ordering every January I find online lol. So far they all do 850 or 900 core and 975 memory.

Thanks for the build @Mitsu™ however I managed to find a 750/900 cex/pex build flashed it with a new usb and it works and does report the right info consistently meaning I had multi bad flashes and my old usb is just bad . Thanks though I'll post my RSX info when I make a dump of the lvl 1, however all stable no issues and temps are around high 50c to 46c but normally stays at 49/48c. Lastly for record does also help fallout new vegas with dust particles and vram with loading all the packs when leaving the starting area, I'll do more testing soon I'm going to try a few games I have laying about vs from drive just to make sure I get consistent results as to not have the storage or iso loading added in so I'll try and find a few games I know have issues with the PS3

edit
as for temps mx4 clean application, cleaned out and I'm more then sure the fans kick in at 60c so I'm guessing whatever stock settings webman or evilnat has applied is in effect.

 

[Tanzu15]

@Mitsu™ so how's the 800/1000 been doing?

 

[Mitsu™]

@Mitsu™ so how's the 800/1000 been doing?

Still great !
The Crysis HD test is passed, and I've tried several games without issues at all.
GT6, Oblivion, NieR RepliCant, Drakengard 3, Asura's Wrath, Sonic Unleashed... No artifacts nor crash.
Temps are great, practically never approaching 60°C at 45% fan speed. Even 35% fan speed is sufficient in fact, but the cooler the better.
I let it go to 70°C just to see and everything is fine !

Awesome I do the same thing too. 45% fan speed is great. And yeah if crysis HD passes our tests, it pssses every other game test. I've tested that myself. I only need to extensively test crysis HD to know the OC is stable accross all games. You came a long way before you couldn't even get much on your older PS3, now with this one you can do 800/1000 which is a massive boost.

I sincerely thought that 650/900 on my 2004 slims was great, but 800/1000... It's awesome !

It will make a big difference in many games. Glad to have you in the 800 club.

I use gt6 on nurburgring cockpit view 2 laps to stress test. Would crysis hd still be a better option?

Yes. Crysis HD is so stressful on the gpu. I think it's the most stressful. It's also the most sensitive to overclock. So if you see any artifacting. You know you gotta turn it back another 50 on the core until you see none. It's such a blessing to have this game as a stress test on PS3. Also it's easy to start a new game and get into benchmarking fast. It's easy for me to set up when I buy new Overclocking PS3s.

 

[Mitsu™]

I've done some more tests at 800/1000 :

• Metal Gear Rising Revengeance works perfectly, it's weird to play it at such speeds without shutdown haha !
• Shift 2 Unleashed do not exhibit artifacts at all (This game is a good test for this too, IIRC).
• Gran Turismo 6 1080p now has a solid 60fps, even with rain, etc...

This is really impressive !

 

[Alex1992]

Mitsu can you please make beta v9 850/950 if it doesn't bother you.

I just received my next January 2011 2501B and even without repasting, JSD board, 362 day up time, it eats 900 core for breakfast fully stable zero crashing and zero artifacts. Now I have 2 900 core PS3s. January 2011 is really where all the top tier chips went to. @RIP-Felix

 

[Cosmic-R]

i havent been following this too closely since i have a metldr2 console, but is there any tendency of later consoles being able to run higher clocks ? or is it just a silicon lottery ?
i wonder if cfw ever comes to metlr2 consoles what a 28nm rsx could do, that is if sony didnt cheap out on the vrm and cut it to exactly what it needs stock

The later the date the higher the OC.

Is true if we repaste the hardware with a new thermal paste it can handle more overclock then before?

Later date = better probability to find a PS3 with a CXD5300GGB RSX.
That said, there is still a part of luck, as someone got a 25XX 1A(=January/February/March 2011) with a CXD5300A1GB in it (the earliest RSX you can find in a 25XX, OCing less).
Sony getting rid of its old stocks, probably.

Hy, I've been watching this thread for a while
Until now I only had a fat PS3 CECHH with the 600 750 OC

I've just bought a PS3 slim datecode 1A and RSX model CXD5300A1GB. What OC would you recommend to start with?

With the 28nm RSX there are only 2 VRAM chips (against 4 before), so I don't know.

Nope. While good temperatures can help stabilizing, if an OC need that to be stable then you shouldn't keep it.
A good OC must be stable no matter the temps.
