It's not that great. I've never even heard of the brand, but the price isn't right. You'll need triple channel RAM (three sticks), and at that price, it'll cost you $195. For $5 less, you can get these excellent sticks: G.Skill Pi 3x2 GB 1600 mhz CAS Latency 7. They're a lot faster.
Also, the UD7 is generally considered a waste of money. It's extremely expensive, and just as good as the Gigabyte GA-X58A-UD3R that's about $150 cheaper.
