Yes, that's the one I use. I also tried the other copy-mem patch: http://www.heywheel.com/matthey/Amiga/CopyMem.lha
, but it didn't made any difference. Does it matter at which point the patch is initialized? When I tried it the first time I simply started it from shell right after the system boot. Later, I placed it in the Startup-Sequence after the setpatch command.
