Question About Voltage Mod!

[washo]

hello,
Im looking forward to make the voltage mod but Im not sure if the value I calculated are safe...
the GP32 is by default 200k(R48) and 470k(R52)
BUT Using : 1.25 * (R48 + R52 ) / R52 I think its good to use :
R48 = 260k
R52 remain unchanged ie : 470k
that makes 1.94V...This is still in the 'OK range' B)
I think this is enough to allow 166MHz OC....maybe more :rolleyes:
are those settings corrects or do I need to change both resistors? :unsure:
thx for any hlp

see you :lol:

 

[Robster]

Yeah, that looks fine. 260k unfortunately isn't a standard value - how are you going to make it? 220k + 39k perhaps?

Let us know how it goes!

 

[washo]

Thank you very much for the fast answer...

220k + 39k perhaps

Should be OK
I will tell you ASAP the mod is OK

see you :lol:

DO you think 2.00 volts will kill the gP32? I was thinking off doing this mod or have a store do it for me so I was just wondering.

By the way Robster, your mods for your Gp32are awesome! Maybe you'll find a way how to put a 200mhz arm chip in the GP32! :lol:

Mine is running at !.97 and it is fine.

I think your mod will be fine and yes it will overclock at 166 after you do it.

 

[Drumaster]

And how far can you overclock with 1.97 v?

 

[jonjandran]

I can overclock as high as any program allows.

Oh and as high as my batteries allow. With normal AA batteries it won't overclock high for long. But with 2000mah NIMH I can overclock up to 180.

Thats the highest I can try as I don't have a program that goes higher.

Hi I made the OC mod but there was something strange :
the resistors inside my GP32 were not the same as the things said on cobbleware...
I got R48 = 300 and R52 = 640
instead of 200 and 470
So I changed R52 from 640 to 563 and that give me a 1.91V output but I cant use my GP32 with the FLU on while clocking at 166MHz : what is the matter?
There is no Prob at all if I run it without flu @ 166 or running at 166 with FLU using the AC adapter....

Do I have to change my batteries?
tell me please....(Im using NiMH GP1800)

see you :lol:

 

[jonjandran]

Batteries are VERY important after doing the voltage mod.
I use 2200 mah and it's just fine.

Your batteries might be dying or going bad, I'd suggest new ones.

 

[washo]

OK thx very much for the advice
So I will go for something like 2350NiMH...

see you :lol:
