200mhz Blu?

[Wolfsclaw]

Hello,

i want to get this clear, has any gp32 blu owner here done it to overclock to 200mhz? that would be totally awesome, my gp32 nonflu 'only' o/cs to 156mhz.
imagine snes fullspeed with sound on and very low fs

i think the sopecs of the S3C2400X01 are only up to 186mhz

CPU can go up to 200MHz, bus can allow up to 166MHz, therefore anything above 166MHz will have no effect. Not sure if this changed with BLUs.

Wasn't only the RAM quality that didn't allow to go over 166 Mhz?

In this case, going over 166 Mhz is possible if the RAM is good enough.

are you sure about the bus? anyone tryd it? oscilloscope?
couse iam surre 172snes9x runs faster for me than the 166mhz one

Overclocking Tester I made a while ago: http://www.gp32x.de/board/index.php?showtopic=5546

The result can be rather mis-leading (you may be able to go higher with this test then you can go with something like OpenSNES9x because it doesn't tax the CPU enough), but there should be SOME increase beyond 166MHz if you are correct. There wasn't on my GP32, but there is proof some GP32s have different components then others. Note that my GP32 WAS able to overclock to 200 MHz using this test, there was just no speed increase after 166MHz.

looks like speedup for me

Interesting, very interesting. You're the first person I know of who has a speed-up at 200MHz. Do you have the voltage mod on your GP32, or any other mods? Since mine has no speed-up after 166MHz, yet nor does it crash after 166MHz either.

By the way, while I can see the pictures, I have no idea what anyone is saying in those threads

 

[Josquius]

Wow, so the blu really is a gp32 2?

What are you on? Read the thread .

 

[Vimacs]

theese pictures are not from my gp, they are from the blu, mine gos only to 172, crachs after short time at 180. but also with speed incrase

Do you know where I can get this overclocking tester? I remember that my non-modded flu can clock up to 172 MHz but as no emulator supports it I have never gone further.
[edit:] damn I'm blind...today at least. Sorry, guys.

 

[damaki]

My flu can stand 200 MHz with light on B)
Speed up has gone to 5 (4 for 166 MHz)

I believe this was theorised at one point, but suring the 32 mb upgrade, it was discovered that the memory bus always runs at precisely half of what the CPU is set to, regardless - and the default ram bus has a max of 133MHz. So double that, and the ram would only become a problem after 266MHz had been achieved - long after the CPU itself gave out in all liklihood...

Now, running at that speed should be way before quality becomes an issue, so I believe (not sure, though), that that idea is no longer the generally presiding one. I could, as always, be wrong, though...

 

[generalnmx]

Not to mention running at 266MHz would make your GP32 last for about 30 minutes Heck, even 200MHz would probably be about an hour.

Is it not dangerous overclocking your gp32?
On the website of joygp they say that higher than 120 is not recommendable?
And why are some gp32's made of other components than other gp32's?

 

[PinkSpider]

Its safe!!

 

[damaki]

And why are some gp32's made of other components than other gp32's?

If a firm which provide gamepark with some component cannot provide enough, becomes too expensive or whatever they have to change for another one the quality won't be the same. There's also another issue with electronic components, all produced aren't equal in quality. That's true with computer's CPU, ram or whatever. Sometimes they're better sometimes just average (not worse because they are tested), that comes from some production processes which get quite random results sometimes.

I think nearly every one runs at around 150mhz - 166mhz when playing things like SNES, GEN, GPCinema Etc... so Overclocking is safe...

Also GPCINEMA Was Commercial Software and It allowed you to Overclock up to 166mhz so the company that made GPCinema would have to have done Tests to make sure running at 166mhz is safe before they could start selling the software that allows this
