None in particular. What you should do is look in that CPU-Z program at the mainboard tab to see which motherboard you have. Then go to somewhere like Guru3d.com, TomsHardware.com or similar and look at which memory they have installed during their benchmark testing and reviews. You can't go wrong by copying what either of the places are doing.
Most RAM has a lifetime guarantee, so if you contact Crucial, they're likely to replace it at no cost to you. Show them this thread and ask for RMA.
You're welcome.
