I'm trying to get hold of some SO-DIMM memory with ECC (It's part of some hardware for some research I'm doing) which is proving to be tricky. First of all I can't actually find SO-DIMMs with ECC, but I can find SORDIMMs which do. As far as I can tell a SORDIMM is exactly like a SO-DIMM apart from it's registered and generally comes with ECC, does anyone know if this is the case or if there's any other differences I should be aware of (I'll be plugging this into an FPGA dev board, so it needs to fit the SO-DIMM form factor and have the same electrical characteristics)? Second does anyone know where I can buy SORDIMMs with ECC in the UK at a vaguely reasonable price? Digikey UK has some 4GB ones from Micron however they cost £651.87 each and you have to order at least 100.
