Is it possible to use the components/functions of memtest86 to create an inband ecc error generator? In large datacenters it is simply not practical to bring systems up by booting the memtest86+ image. ECC errors could easily be detected through MCA MSRs, or Bios SEL records if there were a tet that was rather good at generating them. Obviously not all memory would be accessible and the OS memory allocator will make this less effective but such an ecc generator would be very useful for large data center operations.
