i did the 128meg upgrade, works great. Metalguys instructions work perfectly.see here:

Mine was 50mhz already so i didnt have to do the cpu upgrade.a 50mhz cpu and 100mhz oscillator should get you there..see this picture:

I was thinking there are some jumper wire links that also need to be moved for 50mhz operation but i am not seeing them,so i must be thinking of something else.

good luck! you will love 50mhz and the gobs of ram.


Yeah, both of mine are already 50MHz... need to do that 128MB upgrade.

There might me more to this then just a 50MHz cpu and another oscillator. If I'm not mistaken, some components have different ratings. The Derringers that were delivered as 50MHz models had some faster components (gals?) on the board. On amiga.resource.cx is a good high res picture of the 50MHz version, but unfortunately not of the 25MHz version.


I want to say my first 50MHz one was actually upgraded.  It's in my 1000 in controlled storage.  Next time I'm out there I'll have a look at it.  If it was upgraded I'll take some pics.

I looked at it today. I have no indication it did not come as a 50MHz board.  It looks like I managed to snag two Derringers 50MHz from the manufacturer.
