I’m having memory problems with my 6100K8MB-RS motherboard. I have tried four different memory modules they are all DDR 400. Which this board take. When I install they I keep getting an short beep then a 2 sec pause followed by the short beep. I know it’s the memory. The data specs call for a single channel DDR DRAm interface. Can you have me with this. I don’t know what kind of memory it is. I can use DDR260 / DDR333 / DDR400.
