RAR archive of 1.01 MB covering board MS-7511 revision 1.2, a code that follows MSI's MS-xxxx motherboard numbering even though no brand appears in the name. What the package holds is not stated, so check the extracted files before use. Service data like this helps follow the CPU and memory supplies, find the controller driving each phase and identify test points for measuring standby voltage. Since several revisions of MS-7511 circulate, compare the revision silkscreened on the board with 1.2 before relying on any reference designator.
