They can put what disclaimers they like, bottom line is this. If they sell good that are not fit for purpose then they are liable for making reparations. It is more than reasonable to expect components that are sold as combo items in this fasion to work together. At the very least you should be able to return the goods for a full refund (Including postage).
If you dont fancy taking a chance then by all means phone MSI like i said at the start, you really have nothing but the cost of a phone call to lose.
