I need to upgrade the memory in my pc. The processor is a bit old, intel E6300 Conroe, 1.8ghz, FSB 1066mhz. The mobo is biostar tp43e combo. It supports both ddr2 and ddr3 (not at the same time). I am currently using a single chip 2gb ddr2 ram. I want to upgrade to 2x2gb ddr3 1333 mhz RAM. I want to know if these are compatible. The mobo supports this memory. Do i need support from the cpu also for this upgrade (I remember reading somewhere that fsb frequency is relevant to this, cant remember) or is that irrelevant. If I cant use this, whats the best option.
