I've recently purchased another kit of the EXACT same ram i had for my computer. I had 8 gb (4x2) previously installed, now I have 16 gb but 8 gb are not workig or being recognized. They are the EXACT SAME KIT simply bought two years later. Windows only seem's to recognize 8 gb of the total. I've tried every single RAM combination that was possible and nothing made a difference but it started with 8 gb of installed RAM every single time. CPU-Z AND BIOS can read ALL of the dimm slots, they both say that all of them have the RAM that i can speaking of there but for some reason it is missing. I cannot find a manual dual channel override, however i have changed the timings and made sure everything is how it should be. I currently have it on X.M.T. mode, DDR3 - 1600MHZ - timings at 9-9-9-24 which is what is suggested on the box. To be clear: I have 4x4 currently installed, two different kits, exact same product, exact same timings, all are being read but not all are working in unison. Please let me know if you can help me out!
