Hi Starkyller, If my goggling is correct also taking your current system specs. in your profile into account. I don't see why your Ram wouldn't work from what I can see your running 2x2GB DDR3 1333Mhz Kingston sticks. Although the model number isn't on the supported list for your new motherboard I would be very surprised if your old RAM stick's wouldn't work in your new Motherboard. However never having any experience with ASrock board's I am not 100% certain of this.

It's pretty unlikely that it wont work. If it's not on the supported list, there is a chance, but it just means they have not tested it themselves on the motherboard. Kingston are a popular memory brand so it should be fine
