What is the part number of the memory modules you added? Have you tried to use these memory modules by themselves?
Usually, it is recommended using the larger memory in the blue slots first. Additionally, make sure you swap the memory around to make sure it is not an issue with the slots.
I had the modules installed incorrectly, I had four installed in the first channel group and only two in the second group, I put three in each group and now it's all up and running.
Thanks for the help.
