Hi, I have an old slow pc which had only 256MB of SDRAM installed, so to speed it up I decided to up the memory with a1GB stick of DDR memory. The mobo, a ECS K7AMA has 4 slots, 2 for SDRAM and 2 for DDR ram. I removed the sdram beore I installed the DDR ram, I changed the jumpers as necessary but the system seems to think there is only 32MB installed which makes for a very slow pc, running XP. I have tried both slots but it makes no difference. I I revert back to the SDRAM, changng jumpers that is recognised fine.The memory is from Crucial and is the type recommended by them on their website. Any suggestions as to where I may be going wrong?
