My computer is currently running with AMD 955 3.2Ghz and a MSI 790FX-GD70 motherboard. As you know that this motherboard is new generation board and for that reason I have installed it in my computer a week ago. However my computer still uses only 4GB RAM. Now I am not satisfied with its speed. For that purpose I would like to upgrade the RAM to 8GB. Can I run the 8GB RAM for this configuration. I am not thinking about overclocking the system. I also need a good CPU cooler or heatsinker for this motherboard so that there will not be any obstruct with RAM slots. Please offer me a quick reply.
