DDR3 16GB 1600Mhz DIMM PC3-12800 1.5V 240 Pin Desktop Memory RAM Non-ECC for Socket AM3 AM3+ FM1 FM2 Motherboard

bought 6;of them tried in 3 different computers using the ddr 3. The ram would never register or be detected. I tried the ram by itself as a set different porch. no matter what, they just would not pick up. I put another RAM that runs the same frequency. thinking may be okay. the computer can't support the frequency at 1600 but my other ram worked fine at 1600mhz. so I think the ram is just trash. Yes, the computer does support it because I put two 16 GB chips at 16 MHz in one of the computers already and they worked fine on both systems
