This is from the manual of your motherboard and it might explain why you can only see one dimm working.


Hope that helps

That specific model of RAM is not listed as being supported by your motherboard. Check for compatible models here:


That being said, sometimes RAM will work fine even if it's not officially supported. Be sure that you are inserting the RAM into slots of the same color, either both black or both blue. If it only recognizes 4GB in those slots then move them to the opposite color and see if it recognizes 8GB. If it works in one set and not the other then you may have a bad RAM slot and need to RMA the board. If it doesn't work in either set of slots then you need to return the RAM and buy a supported brand and model.
