doh just re-read OP, above all clocked at 800mhz, i should lower clock?

What's your overclock and OPP?


Mine crashed at 1 Ghz on OPP4, but was fine at 0.95 Ghz on OPP3, or 1.05 Ghz on OPP5

I could be wrong here cause am pretty thick, but am sure ive read somewhere on the board that the way that pcsx rearmed was built that its designed to work better at lower clock speeds (650 was the max recomended in the thread am sure) and overclocking will actually be counter productive and cause more stability issues rather than speeding up the emu.

It should not be a problem, the Pandora is like any other computer and the emulator will simply use as many cycles as it needs. You just need to keep the system stable as a whole, either by increasing core voltage, or backing off on the clocks.


I keep the clock speed high for disabling frame limit (fast forward). I'm not worried about battery life so the slightly higher draw does not concern me.
 
Wow. Final Fantasy Tactics works very fluidly now (still can't save though, but save states suffice nicely). Very nice work indeed.

I'm pretty sure that Phelsumania's right. Stuff that uses NEON, like this, works better at lower clock speeds. :p
 
Long story short: every operation in the CPU needs an intrinsic amount of time to get done called propagation delay. If you overclock you shorten the timing restraints that these operations have to complete and eventually, if the transistors can even switch that fast and not suck too much current, you'll make the operations not completely reliably. Causing crashes and stuff.


It's not that NEON makes overclocking worse as much as the overclocking was never fully stress tested in the first place. If the old 65nm OMAP35xx really did reliably overclock so high TI would have probably sold higher bins to capitalize on it. It's for this reason that Craig shouldn't make comments about how "you can just overclock to 1GHz."


More on topic: I'm sure I'll be getting something from notaz to help debug GT2 and Xenogears. Please continue to use the default GPU plugin until it doesn't work, and when it doesn't make a savestate to reproduce it. If it then works with the other GPU plugins we'll know it's a problem with the GPU code. Right now it really needs the testing exposure, the code wasn't even used to play actual PS1 games until less than a week ago.
 
Probably a stupid question - but which of the GPUs listed in the options is the new GPU?

It does not run better at low clock speed, its just that there is a higher chance of instability while running NEON code.

I haven't. I have instead been careful to have the users research the maximum average over clock and also things which effect it.


We have always understood what you have just explained (and TI have spoken about it too), it's only now that it's having an effect, but the other effect is the overclocking isn't needed anymore so there isn't really any issue.


I actually prefer things this way, to be optimised and for as much of the hardware to be used as possible with the CPU as low as possible, going right back to the GP32.

Just to check I've not got a duff bin/cue - anyone played Soul Blade? It plays perfectly, but the music runs in a constant 1 second loop... Is it just me? FWIW, I run my Pandora at 1GHz (standard OPP) and get no problems in PCSX-ReARMed with any of the games I've tried. I've underclocked to 500MHz to see if there's a difference, but the music still loops.

By far the best Christmas present i have received this year.. cheers notaz!


Everything i have tested so far runs flawlessly at 650mhz.. except Magical Tetris Challenge (worked fine on previous builds) which now continuously pauses, pressing start temporarily resumes the game but this behaviour repeats every few seconds..?

Bizarrely enough I was just trying this out. I've the same issue, thought it may have been a broken file, but if you're having the same issue I think it may just be a compatability thing. Not sure how to deal with it...


But this is a great update of a fantastic application, thanks very much for it, guys :)

Just played a bit with MEDIEVIL II and its work :) .Before the game was not playable..thank's again ;)
 
Gran Tourismo 2 (UK/Euro; Arcade Disc) crashed when selecting "B-Class Cars" when starting a new race from the menu.


When I restarted PCSX-Rearmed after the crash, I got blocks of colour instead of the graphics. Not quite sure what that was all about


I tried Tony Hawks 2, that seemed okay from the little I tested


Edit: Changed the GPU plugin to PCSX4ALL, and GT2 worked fine

I get the sound problem with Lego Racers.


Wow, nice, no overvoltage for 1 ghz? You must have one lucky chip!
