I am trying to Upgrade an Acer Aspire T310 Desktop from 1 x 512mb PC3200 DDR Ram to 2 X 1GB DDR PC3200 Ram.

According to the Acer website, the MoBo supports 2GB in two slots, which is what I have tried to install.

When I put both 1GB Rams in, the PC is very unstable, and keeps crashing. When I run memtest with both in, lots of errors come up immediately. However, when 1 GB is installed on its own, it runs fine. I have tested both sticks of Ram and individually they seem fine.

I have currently installed the 1 GB with the original 512Mb Ram,, and all seems ok.

Why won't the 2 X 1GB work? Any ideas?

Thanks
