Memory Test Option We only sell high quality memory modules. All Products had passed through the manufacturer's testing procedure. However, if you would like to eliminate the chance of a DOA product, we would recommend you to choose the memory testing option. For a small fee, our technicians will test the memory through our Enet Certified Testing and make sure they are in perfect condition before we ship them to you. Please note that this option does NOT cover compatible issues. Please check your motherboard's specification before order.
