Hawk Ram Board. Crystal?

[Retrofan]

Hi:
When I bought my A1200 two years ago it came with a Hawk Ramboard and later I put 8mb to it.

A couple of weeks ago I bought a FPU with 40Mhz that seemed ok for it:

Ok, I've inserted it, but still haven't tried it. I've noticed that there is a socket for a crystal, and reading the instructions of the Hawk it says:

"The Amitek board also contains a socket for a crystal which regulates/controls the overall speed of the FPU when it is installed. It is smaller than the FPU and silver in colour....."
"Before installing the expansion board into your computer, it is importan to ensure that the crystal is not faster than the FPU fitted. Any mistakes could result in the overclocking of the FPU and damage to the chip which will void your warranty."

I'm worried now about my warranty..jeje..., no I don't know which is the fastest/convenient crystal I can put for this 40Mhz FPU.


I've seen this photo using 32Mhz http://www.google.es/imgres?q=amiga+...t:429,r:0,s:32
but I think that FPU has less Mhz.

So, just a fast question: Which is the fastest crystal I can use?

EDIT: Is it perhaps 40Mhz? (seems a lot) So simple? This for example? http://www.ebay.es/itm/40MHz-Xtal-Qu...item2eb8cba2eb

40 mhz is the fastest oscilator for this fpu.

Hi Retrofan,

"optional PLCC FPU - can run at 14.3 MHz or up to 40 MHz with an oscillator"

It looks like 40Mhz is the max.
