I recently put together an Asus Rog Strix b350 f with a 1600x cpu, and Flare X 3200 RAM. I briefly tried running it at 3.8GHz, but did not leave it there. The requested vcore by the cpu is 1.375 which seems high so I have run a negative offset to reduce it some. The load voltage reported in CPUZ and Hardwareinfo 64 was showing 1.352 up to 1.384 for many tests. Now the load voltage will only go to around 1.21 even if I put the bios voltage back to auto (1.375). Any load on the cpu will cause the monitor to black out and I have to either pull the plug from the power supply or switch it off and then back on since the power and reset buttons will not function when this happens. There are no extra lights showing on the board when this happens. Even trying to run the Sims 3 game made it black out. It rebooted on its own while typing this. I am running everything at factory default in the bios right now (even the RAM at 2400Mhz), but it will constantly black out with any load applied and at random while doing nothing. I do NOT have patience for this and will not play with this thing for long. I will just go back to an Intel build if this keeps up. I wonder if the board itself is a lemon. I wonder why the load voltage no longer goes to what it did before. I can try sending this board back and get an x370 if it will do any good.
