Big was my surprise to learn that our old Pentium 3 PC from 1999 has ECC support in its three RAM sockets. The problem today is the artificial paritioning of the market. It seems nigh impossible (at least in the Intel world, please correct me regarding AMD) to have ECC RAM in a normal Home PC these days, especially in an ITX form factor, as I am currently investigating. There are Xeons for the 1150 =E2=80=9Cconsumer socket=E2=80=9D, but ECC is only supported by server= chipsets such as the C series. Those come either on ITX boards with abysmal I/O capabilities for home use or on high-power workstation ATX boards that cost a small fortune. *sigh* I would have liked the aspect of a system that tells me when something goes wrong, but there seems no such thing for my requirements. So I must help myself with file checksums when dealing with my archive disks. --=20 Gru=C3=9F | Greetings | Qapla=E2=80=99 Please do not share anything from, with or about me with any Facebook servi= ce.
