I don't know if i can because i bought used ones from Ebay but i think he sent me the warranty would that allow me to return it? But it may only give the money back to seller. And they are Teamgroup, I might as well upgrade my motherboard as that would be a better investment as these sticks are actually pretty good, but i'll see.See my last post, I updated it.
Also, you may be able to return your memory kit to the retailer and get something that is compatible. I much prefer G.Skill above all others for gaming and enthusiast builds, followed secondly by Corsair. I try to stick to the Ripjaws and Trident Z sticks from G.skill. Their value memory or Aegis are for bottom feeders.
For Corsair, the Vengeance is ok, but isn't particularly terrific. Their Dominator platinum is much better and is on par with the higher end Trident Z sticks. Kingston is ok as a third choice but the ONLY Team group memory I recommend are kits that are CL14 because those will be Samsung B-die if they are 3000-3600mhz sticks.
