X9DRE-TF+ motherboard only supports Intel® Xeon® processor E5-26xx and E5-26xx v2 family. You read the specification of that chipset, http://ark.intel.com/products/66243/Intel-BD82C602J-PCH and saw that it may support E7-2890 v2. But because E5-26xx V2 uses Socket R and E7-28xx Series is using Socket R1. Therefore, it will not work.
