Finally, the DDR4-4000 Patriot Viper Blackout 4 PVB416G400C9K memory kit arrived, installed without any problems on the XMP profile with a frequency of 4000 MHz and timings 19.19, 19, 39. It successfully passed all stress tests, shows high speeds and stability. I got into the be quiet cooler without any questions! DARK ROCK PRO 4, without removing it, since the height of the strips is only 42.6 mm. A big plus is the use of Samsung B-die chips. For those who do not want to bother with overclocking is the best option. For those who want to overclock the memory has a good overclocking potential. To ensure cooling, it has massive radiators. Strict black appearance gives solidity to the kit. In general, I advise everyone to buy.
Relatively compact dimensions of the radiator;
Good overclocking potential;
Limited lifetime warranty;
Nice strict design;
Use of Samsung B-die chips.
