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

Install the latest webMAN MOD then use http://0/edit.ps3/dev_hdd0/wm_res/VshFpsCounter.yaml

Follow the instructions in the file then SAVE. You will see the changes the next time you load VshFpsCounter.
Code:
version: 1
overlay:
   displayMode: XMB_GAME # Available options XMB_GAME, XMB, GAME
   position: TOP_LEFT # Available options TOP_LEFT, TOP_RIGHT, BOTTOM_LEFT, BOTTOM_RIGHT
   showFPS: On
   showCpuInfo: On
   showGpuInfo: On
   showRamInfo: Off
   showFanSpeed: On
   showFirmware: On
   showAppName: On
   showClockSpeeds: On
   temperatureType: BOTH # Available options BOTH, CELSIUS, FAHRENHEIT

If you load the plugin through boot_plugins.txt (I do not recommend it) you have to the install the latest plugin 2.6


I don't have a dev_hdd0/wm_res/ folder, only /dev_hdd0/tmp/wm_res
what gives?
 
Has anyone tried to increase the voltage through a hardware mod?

how are you guys stability testing? how long do you run red dead redemption for before crash, and at what point in the game, idling after the intro scene?

I have a cechg01 that is stable in game but would crash sometimes in xmb or during downloads in "the package downloader", probably because the 90nm chip cant take a small OC

OCing the 90nm RSX is a good way to make it die even faster. It's like speedrunning a YOLD. I did that to my CECHC and it got unstable within a month. Be very careful

There's an alpha port of Quake 2 being worked on, can be possibly used as a benchmark, details here:
https://www.psx-place.com/threads/yamagis-quake-ii-port.37215/page-3#post-372577



v0_02

1080p:
92.5s: 7.4fps
overclocked CFW (RSX overlocked to 600/750)
77.2s: 8.9fps

v0_03
1080p:
13.0s: 53.0fps
overclocked CFW (RSX overlocked to 600/750)
11.7s: 59.0fps


make sure you have webman fps overlay off, it messes with the console display of the game

My tests with 600/750 RSX CFW 4.90 on a slim using a killawatt showed no power consumption increase, and a 10-20% increase in performance.

20% increase in yamagi quake 2 alpha v0_02
20% increase in bioshock infinite

Could someone please make some firmwares with higher clocks?

Put them in an archive and make the password "i_have_a_hardware_flasher" if you want to <3
(I don't even see lv1.self files for higher clocks? I wasn't able to use the latest ps3mfw-builder-0.2.1-mod-master either, since the keys did not line up with the files in this tutorial:

)


afaik, 600MHz core and 750MHz ram is the last stable clocking that works. though, there are posts saying that even this OC isn't stable on specific games (Red Dead Redemption was one of them)

though, if users want to do their own testings, I could add higher clocks to mfwbuilder

edit
now I rethink of it, probably won't do this, cause it could harm the PS3 to the point, where you cannot re-install firmware without a flasher, cause of instability issues
Please make them?

Where is RDR1 unstable? I ran the intro and idled at the start of the game for a few hours. Where are people having crashes w OC in rdr1?


And even if the higher RSX speed only causes spontaneous crashes, it's still enough to mess with the firmware update (since you have to go through the XMB or Recovery mode) which then will also require a hardware flasher.
The 650 MHz core clock has been tested on devkits with use the best binned chips and it's not stable, that's why for the initial tests lv1 was loaded over the network, never written to the ros.
how do you load lv1 over network?

Exactly. People don't understand that overclocking without changing voltage doesn't increase temps. It's why this is just free performance.
That's just not true.
P = C(V^2)f

P is power, C is capacitance, V is voltage, and f is frequency
Since voltage is squared it affects heat a lot more than frequency. But increasing frequency will always increase power consumption as well.

However, that doesn't mean overall system will use more power, it's sometimes possible that overclocking the gpu will less the load onto the cpu in a certain scenario and while the gpu die will be hotter, overall power consumption may decrease. It's complicated.



I have ordered a second CECH-25XX to install the 600/750 Overclock on, I have also ordered the necessary equipment to record PS3 footage so if I get time I will do framerate comparison if I can find a good framerate analysis tool. I will also try and compare temps before and after.

I have also a power usage wall plug monitor, if I can figure out a way to integrate this information into the video I will but no promises anything will come out of this.

I wondered for a long time. If overclocking which includes raising the voltages and the clock of the RSX is possible why undervolting isn't possible. If we are able to raise the voltages of the RSX we should be able to lower them too right?

Current overclocking firmware doesn't change the voltages. I don't know if the voltage is the gpu voltage is constant, it probably is.

If someone can figure out how to control the voltage in software, then it should be possible to undervolt as well.

hi, could you reupload the file to another cloud storage site? because zippyshare is closed. thanks
 
Hello guys! New here. I just got myself a PS3, delidded, changed the thermal paste, updated do Evilnat's 4.90 CFW, but since I don't have a working BD drive, I'm unable to install the OC firmware. Is there a way to add the OC to the noBD firmware? Thanks!
 
Im running 4.90 OC cfw on my cecha01. Temps in last of us is max 67c cpu/ 60 gpu fan boosts to 35%. I have only repasted the chips without delidding. I am very happy with the results and not concerned with longevity of the chips. The only thing we need to worry about is excessive heat cooking the caps. But thats inevitable. Just prepare to replace when they do go. Thanks for the awesome work!
 
Thanks for the overclock cfw.
tbh, why stressing RSX even more, when it already has too high failure rate, especially on backwards?
but this is just my opinion.

about voltages, for retails it is still unknown afaik, where it is done
I can provide you in pm higher clock rates though.
Hi @haxxxen, would you mind send me a patch for PS3UPDATE.PUP to rise the core to 650mhz?
I can't PM you maybe because I'm new, also I'm on 4.90 Evilnat Cobra 8.4.
