Hello Henrik, many thanks for your information. I have checked the MSI forum entry. They say that the information about SVM in the overclocking section could be wrong. As I do not see this value somewhere else where I can configure it it seems to me that this output in this BIOS part is not correct. I will try to find a way to confogure SVM in the BIOS or contact MSI about that.
