Yes, the memory is compatible with your motherboard and it will fit perfectly into your motherboard. It will work just fine. If you need less fancy memory then you can try the following website for compatible value ram - http://www.memorystock.com/memory/MicrostarIntH61MP31G3.html

Let me know if you need any info. Cheers!!
