I had an old desktop with D101GGC Intel motherboard and a DDR1 512MB single sided RAM. This RAM is old and was purchased long back in '06. Recently I purchased 1GB DDR1 double sided RAM.
Now the problem is I can use either of these RAMs individually but not together on the same machine. The machine works fine and the memory is recognised correctly if I put only 1 of the RAM. Please note that the MoBo is single channel.
But If I put old 512 MB in slot 0 & new 1 GB in slot 1, the machine simply does not recognise the RAMs and I do not even hear the initial boot sequence memory beep. If I swap the slots, I do hear the beep but nothing happens further. The computer hangs at the initial boot screen.
Any thoughts on this?
