Review on Patriot Memory VIPER 4 16GB (8GB x 2) DDR4 3000MHz DIMM CL16 PV416G300C6K by Mateusz Grzesiak  (M ᠌

xpm profile refuses to work stably with a configuration of 4 memory sticks, memtest shows that the memory is in order, it works only at stock frequencies (2133 MHz), I tried to increase the voltage to 1.45v, lower the frequency to 2400, the memory is simply inoperative when 4 sticks are connected (2x8 work stably). In support of patriot memory, they are talking nonsense about the increased load on the motherboard when 4 memory sticks are connected and offer to send the memory to Taiwan at their own expense, so that I POSSIBLY replace it. Changed 3 mat. None of the boards worked with xmp profile (latest version bios). I took memory from another manufacturer with higher frequencies, everything started up without any dancing with a tambourine.
