English Amiga Board - View Single Post - Overclocking the TF330. From success to failure.

During the week I successfully overclocked my TF330.

You can watch my video on it here: https://youtu.be/BG2vLDR-1EY

Long story short I swapped the 100mhz crystal for a 108mhz to bring the clock speed up to 54mhz. All was working fine. I used the machine that evening of the overclock for several hours without issue.

Going out to it this morning though and it's dead. Power on and black screen only, occassionaly you'll get the jingle with no display or sometimes the display signal will drop off.

First thing I did was to go over my soldering at the crystal which was fine.

Then I tested the console without the riser then with the riser but no tf330. Fine.

Then I tried the tf328 in the riser and that's fine too so nothing wrong with the console or the riser. (I didn't think there would be but you need to check these things).

So I then swapped back to the 100mhz crystal and same result. Black screen or occasional jingle or occasional display drop out.

Last thing I tried was a different 108mhz crystal but same result.

If left on the black screen for any length of time the cpu gets very hot. When running I was getting a maximum chip temperature of about 40°C. After maybe a minute on black screen the pu got to just over 47°C

So what's happened?

Has the cpu died?
Has another chip on the tf330 died?
Would it be worth getting the diagrom chips to test what's going on?

Unfortunately I don't have another 030 to test on the card.
