I have recently built a computer with a Gigabyte AB-350 Gaming 3 mobo and Corsair Vengeance LPX 3000Mhz RAM 16GB 2x8. On my first try with booting up the system, the motherboard lights indicated a CPU or RAM problem and would not POST. I removed a RAM module and everything booted up. I was able to install Windows 10. I removed the "good" stick of RAM and replaced it with the apparently "bad" stick in the same RAM slot. It would not POST. I again swapped the modules, and the computer would boot again with the "good" stick.
I entered the BIOS and changed the XMP setting to Profile 1 to get the RAM speed to 3000mhz and the voltage to 1.35v from the default of 2133Mhz and 1.2v. The computer booted normally with the "good" module. I again attempted dual channel mode and it would not POST with the new RAM speed settings. I replaced the "good" module with the "bad" one again, and it would not POST. I have tried different slots and none of them have worked with the "bad" module. As it stands based on the testing I have done, it would appear that one of the RAM modules is defective. Has anyone else encountered a similar issue? The RAM is brand new so I'm not sure if I just got unlucky with a bad RAM batch, though I suppose it is possible I could have fried it through ESD when installing it.
Returning it shouldn't be an issue. Does anyone have any other suggestions on what I could try? I have read everything from RAM voltages, to bent CPU pins, to a defective mobo could also be a cause. I have not updated the BIOs and I have read that Ryzen CPUs can be finnicky with RAM.
Update: I've tried changing around some of the timings manually to no avail
