| dunno for sure about that one, but the opening needs to be a bit smaller, for one.
the meme heatsinks never mate properly to mem, because of the way meme is mounted to the card, not the artic heatsink, so you have to use white silicon paste for the mem.
the x800 heatsink for the gpu should not touch the mem. if anything, they should have a waraparound peice that covers both sides of mem, so that the tmep between both banks is equal.
i could go on....
