my board Asus p5p43td and it states incompatibility with ram dimms made up of 256 Mb chips or less. This spec is hard to find and I was wondering how to tell as most of the brands in the manual are hard/impossible to find and this is not a well advertised spec. Crucial memory I am running is technically incompatible but works single channel one 2gb. It doesn't read as fast as it should either. so in summary: How do I find ram made up of chips larger than 256Mb so I maY upgrade without issues and use my other ram in a different build?
