I have just assembled a system based in the P4SPA+. I am using\nCrucial 512MB PC3200 DDR memory modules, I flashed the BIOS to 1.0a.\nIn order to have the memory subsystem run in Dual Channel mode it says\nto populate dimm slots 1,3 and / or 2,4. When I populated slots 1 and\n3 (The Blue Slots) I ran into all sorts of problems. I could not\ninstall windows as I received multiple file copy errors and finally\nthe memory error long beep at startup to indicate a bad module. While\nI couldn't load the OS with both modules, it would work somewhat with\neither module in slot 1. However I would still expierience booting\nproblems. When I placed the modules in slots 2 and 4 all of the\nproblems went away and the system has not had problems booting once.\nAny insight into this would be appreciated.
