Is your Fastmem/Vampire board popping off your a600 CPU

kipper2k · 04 June 2014, 15:49

Hi All,

I may have found a solution for those of you that are suffering from your A600 fastmem/accel/Vampire board that keeps popping off your CPU. Here's a pic...

I have identified what could be the problem in the 2 yellow rings ...

i built a board and done a socket which fit perfectly on the V1.5 mobo and i could actually lift up the motherboard by the socket and shake it a bit without it coming off. When i tried the same fastmem board on a Rev 2D motherboard it kept popping off. So after being puzzled for a bit i found out that the resistor on the Rev 2D motherboard was in a slightly different area and causing just enough interference to cause the board to keep popping off, so i recommend you put a nice big cutout in the bottom of the socket because as soon as i widened and deepened the cutout it now sits rock solid

Post your results below

When I bought my Vampire from Igor last year it came with this "break-out" already.

I trick that I can recommend to get the Vampire really well "fixed",
is drilling a hole in through the middle of the socket,
and super-glueing a screw on the 68K and screwing the card on the original CPU.
With this the card is really well fixed to the mobo.

you would have to drill through the pcb as well, which could be sorta dangerous

Nice one Gunnar, adds a bit of heatsink to that CPU as well!
