RMA it all and try again. Why should you lose any more time on bum parts?
I just recently got the ASUS M5A97 R2.0 Mother Board, and I tried 3 different RAMs (Corsair Vengeance LP 2x8GB, two types of those, and Patriot Viper 2x8GB), and each time, it lit up the DIMM_LED light meaning that the RAMs were either incompatible or weren't installed correctly (this was found in the manual). So I pressed the MemOK! button like the manual told me to, but it still did not work. Then I decided to just buy ones from the Qualified Vendor List and got a Kingston 4x4GB [Model No. KHX1600C9D3K4/16GX(XMP)]. It just came today and I tried installing the new RAMs, but then again, the DIMM_LED lit up again. I tried pressing the MemOK! button, and it still did not work. I'm not sure if it's just the RAMs that is the problem, or if it might have something to do with the CPU. My CPU is an AMD FX-6300. Please help! This is very frustrating.
Thanks a ton in advanced.
