I'm thinking about using sand paper or similar to 'reduce' edge on one of chips in 128Mb RAM module.
you can see here (http://www.fileden.com/files/2007/6/28/1218776/Amiga/EDO_RAM_128Ms.jpg) the problem area which prevents RAM fitting in BPPC slot (near FDD).
Since most of that black plastic chip housing is just for protection, it should be safe to remove it partially?
(at least the bit that doesn't lie in center plane)

These modules do fit in the desktop case with only a slight modification to the floppy drive bracket. Take a look at this thread.
A1200 BPPC Desktop SIMM's (http://www.amiga.org/forums/showthread.php?t=35348)
That said you might be able to remove a small amount of the plastic carrier, but it will probably take more than you think to fit. I doubt you will reach a point where it will fit before you hit some of the interconnects. Better to find a SIMM without the extra parity chips.
Good Luck,

Lapping is a well known solution,but not for this kind of reason.
The amount of silicon you will have remove is way to much .You will reach the circuit layers.
But ,you could destroy your accel.By lapping the surface,you may bridge some of the connection and if you mix the voltages with the ram adresses,then your accel will die.
Use the plastic wrap belt solution.It has worked for many,or buy your self some low profile ram modules.
They are dead cheap on ebay.
If it was only about your ram module,you could try it,but you can really destroy youyr accel.

and what would that be? holding the module in place with plastic belt instead of the metal 'hooks'? sounds unreliable, what if it comes loose? the turbo card might get damaged..

I couldn't find any; at least not the large capacity ones needed for OS4.

Use cable straps instead of rubber bands and you are on the save side. I had the same thing done to RAM modules that would not fit my DKB3128. Its running rock steady for years now.

I've used this method before myself, The heat given off by the processor and ram is nowhere near enough to cause the plastic tie to creep.

Same here - I've never seen any low profile- or single-sided 128MB modules. I'd recommend the plastic tie-wrap method myself. Cheap, cheerful, cost effective,

er, do you have any photo of that plastic tie holding the module?
