In accordance with a brand new report featured within the MSI_Gaming subreddit, a latest Home windows 11 replace is halting overvolting and undervolting software program enablement on MSI motherboards that use Intel CPUs. In impact, this implies anybody utilizing software-based overclocking utilities akin to XTU on an affected system, can be prevented from undervolting or overvolting the CPU with software program instruments in Home windows.
Sadly, we have no idea which particular Home windows replace initially prompted all this mayhem. However when put in, the replace mechanically allows Microsoft’s Virtualization-based Safety (VBS) on Home windows 11 methods. Microsoft calls this characteristic “Reminiscence Integrity” in Home windows 10 and 11’s safety app.
Home windows’ enablement of VBS is the actual reason behind the difficulty. VBS blocks entry to sure registers throughout the working system, together with the OC mailbox, which is required to assist software-based overclocking options. Even monitoring apps like CPU-Z might be blocked on account of this registry lockout.
It is value noting that VBS is mechanically disabled in Home windows 10, which is why 11 is the one effected OS. VBS will solely allow itself mechanically if Home windows 11 is cleanly put in onto a system, or from upgrading Home windows 10 to 11 you probably have this new home windows replace put in.
Fortunately, MSI is engaged on the matter and has a brand new BIOS popping out quickly that the corporate says will rectify the difficulty, permitting customers to depart VBS on with no repercussions for older Intel methods. Intel methods with 600 collection chipsets have already got this repair utilized. Apparently, VBS’s lockout might be overridden, and a bunch of different firms have already carried out this with their motherboards.
However for customers which might be affected, the characteristic may be very straightforward to show off. All that is required is to find the System Safety class within the Home windows Safety app in Home windows 11, head to Core Isolation, and disable Reminiscence Integrity to show off VBS.
