Maybe he thought it'd be 66 MHz when you glue two 33's together... :lol:

Just kidding ;-).

I'm thinking $5 each would be fair. Buy multiple and get free shipping.

BTW doesn't the A3640 divide the frequency in half? I think it uses a 50Mhz crystal to get it's 25Mhz speed. Just IIRC, you better check first.

@Red

Yes, it uses a 2:1 multiplier.  The standard is a 50MHz part.

Sorry guys, I´m having the morning shift this week and it´s killing me. Of course you are correct as my A3640/25 has a 50 Mhz crystal, so in order to have it safely overclocked to 30 Mhz or more I need a 60 Mhz or 66 Mhz crystal ... in this case I would like the 64 and 66,66 Mhz crystals  :-)
Anybody got an idea of how far you can overclock a Blizzard 4030/50 Mhz ??? With extra cooler of course  :-D

And I also seem to need a 24 Mhz crystal  :-)
