I have an e-machine W-3052 with a K7MNF-64/1.1a motherboard and will run 2 gb of PC2700 DDR.My question is will my board support high density ram or not?
Memory, whether it's high density or not, should work. I'm not sure who made your motherboard, but I would recommend that you contact whoever your memory manufacturer is and they should be able to verify whether that memory will work or not.
