Dell XPS 27 Memory Issue

Diagnostics is telling me my system memory has failed the "moving inversion test" on my Dell XPS 27 (purchased in 2013). The information for my specific system shows ChannelA-DIMM0 8,192.0MB ChannelB-DIMM0 8,192.0MB. I assume this means I have two 8GB SODIMM's since I understand I only have two slots. Is this the system memory being referred to in the test or is it some other memory? If it the SODIMM memeory, is there a way to determine which of the SODIMMs is failing the test or could it possibly be both SODIMMs? Thanks for your help...
