64-bit ImageMagic Instructions

I remember reading detailed instructions with steps for installing ImageMagic 64-bit and configuring CC3+ for large exports. But, I apparently did not bookmark it and my search-fu is completely failing me.
Can someone point me to the instructions? Thanks

EDIT: search that thread for the phrase "ImageMagickCmdLine" Start at the top of the post that phrase is in.
