I've got a 3825 and I'm trying to upgrade the RAM to 1GB, I'm using MEM3800-512D= and after I boot the router I get the message: DIMM 0 is not Raw Card A or C, not supported. DIMM 1 is not Raw Card A or C, not supported. I've tried three different sets of memory and all give the same message. Has anyone seen this problem before? Regards, Ronan
