How did you edit bios for elipda cards? It doesnt work in PolarisBiosEditor, right?
PolarisBiosEditor worked fine for me with both memory types. Maybe it was a different card that other people were having problems with Elpida on. If you have one of those cards there is a thread on the ethereum community forum on how to edit it with a hex editor.
