I would have gotten on this deal last time they had the special going on, but it says, "This module is tested and guaranteed to work on motherboards based on the AMD 760, VIA Apollo KT266, VIA Apollo Pro266, ViaP4X266, ALiMAGiK 1 and SiS 735 chipsets. Not guaranteed with Asus boards."
So would it work with a Asus A7V266? It's a Asus board which they don't guarantee compatibility, but it has the KT266 chipset which they do guarantee it to be compatible with.
I can wait though because it seems like PC2100 DDR prices are dropping, even Crucial's.
