The modpack went over to 64 bit fine for me. And I know for a fact that I'm using 64 bit because I have switchable graphics and I had to go and configure all the binaries in the 64 bit folder to the "performance" setting or else it would run it on the Intel gfx card and I'd get like 15 fps, although if I manually opened the 32 bit version the old whitelist still fired up the radeon. The only thing that has never worked post 64 bit update is matchmaker monitor but it's not a huge enough issue that I have even bothered to try testing it while running out of the 32 bit folder. I'm not even sure I have 6 gigs of ram although I think I have 8, lol. I also had huge connection issues right after the update. I think aslains modpack was probably the smoothest part of the migration.
