Overclocking the A3400 cpu board

[A4000Bear]

The A3640 is easily overclockable by anyone who is experienced in soldering. I, personally have overclocked a number of these boards and they all worked well at either 30 or 33 MHz, depending on how you do the overclock. For more info, go to  www.starnet.com.au/davem/amiga.html

Ooops...

I just realised we were talking about the A3400 board, not the A3640.

In any case, the A3400 is also overclockable, up to 35MHz. I have had one working reliably at that speed for over 4 years now. There is a noticeable and worthwhile speed increase, especially as RAM access speed is also improved.

Since the surface mount CPU is of a later version, these usually more readily accept overclocking than the earlier PGA type 030s. In fact, I have found a heatsink is not required, even at 35MHz.
