The SPD section is empty, under Device Description there are no DIMMs listed. I suspect something went wrong when I tried to run Thaiphoon Burner, it raised an error window saying it might conflict with AIDA64, which i tried to close to abort whatever it was doing, but I think it continued anyway.
Rebooting etc hasn't made the SPD data reappear, is there a driver or something that has become uninstalled?
