Ok, i didnt know where to post a subject but just the information for everyone in the future...Msi is really strange... There are two versions of the motherboard with designation MS-16jb1 ver 1.0. first one is with i7-6700 cpu and sr2c chipset and second with i7-7700 and sr40 chipet. Beside that the boards look identical...and they both have same designation MS-16jb1 ver 1.0. both are ver 1.0. I know that pins are the same on 6 and 7 gen cpu and chipset but they should be distinguished at least with the ver. of the board. I never seen this before. So info is for all to be careful in the future.
