Gp2x Delfault Runing 298mhz !!!

[Paradox]

can someone explain to us non-dev people what this actually means?

from what i can gather from all the deviating posts, the GP2X is running at nearly 300mhz when it should only be 200?

 

[Eolair]

I'd wait until someone like Squidge or DJWillis confirms this. It would explain the medicore battery life though.

Hmm. what about the psx emulator.
If every one have a gp2x thats running at about 250 - 300 Mhz by default.. thats means, every people have tested the psx emulator at that speed..
then the emulator would be pretty slow on 200 Mhz..

or what? :unsure:

or am I totaly wrong..

edit :mabyee i realy should read what this was about, before im saying anything, but i was in a hurry before

 

[Sonic-NKT]

mine runs at 210 default, and the tool only alows clockspeed up to that speed (i looked at the sources its for underclocking not overclocking), still i would be intrested in what is possible can someone compile a changed version

EDIT: when you clock the gp2x down, the flickering and scanlines get really annoying, much more than witrh higher clockspeeds

 

[Tobriand]

I say, steady on there, old chap!

Is there any chance this can be confirmed? Further, does that mean all current programs are actually running at 300MHz? And if so, am I the only one who thinks they aren't performing quite as well as they might?

 

[Sonic-NKT]

not every gp2x runs at 300 thats for sure...
oh my god, i smell a new clockspeed disaster ... *looks at gp32*

 

[ZodiacfreaK]

Hmmmmmmmmmmmm I dont know about this. Some of it makes sense but alot of it makes no sense whatsoever. Well we will have to see. I think this is just a result of a glitch/bug in someone's code but I could be wrong.

I'm not sure that it's reporting the actual default speed. I think it is just an utility to underclock the cpu as you said. Pressing select and applying the 210 setting causes everything to crash on my unit. Movies hang, games quickly freeze. I'm not going to mess with this until I hear what's going on.

 

[Yuglooc]

wow this is totally confusing me. Almost 300 atm??? Can`t believe that.

Edit:
This is what the prog says for me:

Freq: 280Mhz Div 0 (:o running at 280???)
...
940t Disabled (I thought it is enabled all the time atm???)
Sys Freq: 298598400Mhz M 73 P 0 S 0
UCLK :Freq: 95846400Mhz
ACLK :Freq: 147456000Mhz

Is anyone able to translate that? Please?

​

I guess the last three is in Hz, so

Sys Freq: 298,6Mhz M 73 P 0 S 0
UCLK :Freq: 95,8Mhz
ACLK :Freq: 147,4Mhz

And I guess thats where They have gotten the number 298 from

 

[Sonic-NKT]

maybe those flickering problems come only because of the clockspeed, and gp2x which are running at higher speeds dont have those.
hmm i would like to see my gp2x running at 260 to see if the problems go away.

 

[DARKGATE]

:huh: Excuse me boys, but if for default work to near to 300 Mhz, with the utility for low the frequence of processors, we can put to 200Mhz and resolve the problems and the console work at correct valour.
The emulators can be corrects for work to 200Mhz.

Plent me for me english :rolleyes:

 

[nik166]

so you mean the NES emu is not fullspeed while the CPU runs at 300Mhz?? :blink:

:huh:

 

[parask82]

Anybody realised that at 200Mhz there is almost none of flickering brightness of the lcd?So i guess it is a firmware-settings problem and not faulty hardware.Anyone can confirm if there are different clockspeeds among different Gp2x by default?

 

[Radek]

I want just add that 266MHz is not overclocking according to the MMSP2 docs (the GP2x's chipset). So it's believable the GP2x can run at 298MHz as it's only 12 percent overclock. If it's true that some units run at those fast speeds then no wonder why someones are getting short battery times. It might also explain some of malfunctions we are hearing about. But this means that the GPH isn't really competent with firmware as this looks like a very dumb mistake.

Not I have anything against overclocking but specs says "200MHz" so I'd expect to GP2x to run at those 200MHz when shipped. If I wanted to overclock (or even set it to the MMSP2's 266MHz) then I'd do it myself.

 

[xafier]

hmm... I'm not sure about this, personally I'll wait for Squidge, DJWillis, Rob or someone to test what its set at in HH... i know they know how to set it to a new speed, so I'm sure they can print out what its currently set to...

I trust these guys far more than some random spanish guy... no offense to random spanish guys... lol

 

[Javacat]

With every reply from a Spaniard I get more confused <_<

At first I thought this meant you can overclock it to 300MHz, then I thought that the GP2X was at this speed as default, and now I'm just :wacko:


Edit: Just a random thought, but could the varience in speeds people are reporting be due to the different firmware versions?

 

[DijiTao]

/me Waits patiently for reputable source to clarify the situation

 

[Julius]

Maybe the tool just displays random numbers, and someone over at gp32spain is having a hell of a fun time?

​

it's still there, but it's MUCH slower, you see it going down (or up, depending the freq) at different speeds if you try different CPU speeds


also, my dark line on the left (picture here : http://www.gp32x.de/board/index.php?showtopic=22847 ) is GONE at 200mhz!!! :blink:

(well i know exactly where and how it was, so i can manage to kinda see if i want, but it's not noticeable anymore )

but this CPU SPEED thing should go over 210, at least 300 so we can make tests and see the original freq by ourselves

Seconded.

I'm hoping though, that the cores are in fact doing what everyone thought previously- always running at 200MHz (causing big bad battery drain even just looking at menus), because that means that we would see an actual speed increase in 266MHz mode (for UAE and stuff under HH), and could overclock safely close to a stunning 300MHz, giving decent performance boosts for more demanding stuff. Of course, that would be the mother of all battery killers, but would be hellish cool for some things, if you have decent batteries or a mains adapter Otherwise, it's the same worry as many- we thought some stuff was working brilliantly at the 200MHz (like MD, SNES etc) and would only get better by setting to the "official" MMSP2 clock speed of 266MHz, but in fact, everything will get slower, and we won't be as far forward as we originally thought.

Maybe the tool just displays random numbers, and someone over at gp32spain is having a hell of a fun time? biggrin.gif

I really hope so ;P

Pardon my ignorance but what does that mean? That 298 is the sum total of the two processors clockspeeds? Or something else entirely?
