After reading the long thread on here about the pencil Vcore mod I decided to try it.
I've two GP32s so it wouldn't have been a big loss if it all went wrong. I checked the current Vcore before I started and it was 1.78v and then I did lots of experiments and eventually decided on overvolting to 2.01v which allows my 144MHz max overclock GP32 run stable at 166MHz. B)
I even went as high as 2.5v for an hour or so and it provided a stable overclock to 188MHz but a Vcore that high is just too insane to use for long term use.
My other GP32 does 156MHz stable so maybe I should try the Vcore mod on it too and see if it can overclock further than 166MHz with ~2v?
All those people running at 200MHz plus in the original pencil mod thread without using a multimeter to check the voltage probably meant they were running well in excess of 2v and probably more likely to be even higher than the 2.5v I tried. :blink: :unsure:
