Trying to overclock a 532 to 333. I hacked away at one card until it sticked and that one is now set at 333. I can't get the other card to go to 333. I'll select it and it seems to take, but if I try to keep it it will revert back to slower clock.

Any ideas?

Also, what are the disadvantages to the overclocking?

Thanks

It's tricky. Read this:

The bootloader is made so that you must first try a different frequency before it could be set permanently, and if you do not apply a frequency permanently, it would fall back to the previous setting on the next power
cycle. It is still possible, however, that the board is not working properly on the frequency you've applied, so the default (266MHz) CPU frequency can be restored. To do that, power the board with the S1 button pressed, then unplug the power, and when you will turn the board on again, it will have CPU frequency set to 266MHz temporarily, so you will have to apply that frequency by issuing the keep cpu frequency command in the loader configuration prompt.
