I just added some RAM to my PC. The mobo is an Asus Z-97A. I was using 2 4GB 1600mhz G.skill sticks, and added two more of the same. However when I sewed everything back up and attempted to boot, my display did not read any signal. I removed the sticks I had inserted, and everything booted fine. I restarted, went into Bios and disabled XMP thinking this might be causing an issue. Re-inserted the new RAM sticks to the same result - no display. I suspect I may be dealing with DOA RAM, but wanted to ask for a second opinion before jumping down Newegg's throat. If anyone can suggest a step I might have overlooked I would greatly appreciate it!
