I took a set of 2x8 3600 MHz, didn’t do anything, set xmr and she herself took her honest 3600 with timings 17-19-19-39, 3100 is enough for me for ryzen price-quality, holds 3600 in a stress test, VIPER GAMING STICKER Looks like a comb  Igor: use Patriot Memory PVB416G360C7K less than month |
Finally, the DDR4-4000 Patriot Viper Blackout 4 PVB416G400C9K memory kit arrived and installed without any problems using the XMP profile at a frequency of 4000 MHz and timings of 19, 19, 19, 39. It successfully passed all stress tests, demonstrating high speeds and operational stability. It easily fit under the be quiet! DARK ROCK PRO 4 cooler without removing it, as the height of the modules is only 42.6 mm. A major plus is the use of Samsung B-die chips. For those who don't want to bother with overclocking, it is an optimal option. For those who want to overclock the memory, it has good overclocking potential. It features massive heatsinks to ensure cooling. The sleek black appearance gives the kit a solid look. Overall, I highly recommend it to everyone for purchase. efficient cooling; high frequency; relatively compact radiator dimensions; good overclocking potential; limited lifetime warranty; pleasant strict design; use of Samsung B-die chips.

Defective item encountered. And not just by me. This RAM is a "hit-or-miss" lottery. No. Defect. |
For serious people
Patriot Viper 4 Blackout DDR4 is a series of high-frequency RAM from an American brand with a strict, conservative design without backlighting. You can choose from paired sets with a total volume of 8 or 16 GB with a frequency of 3000 to 4000 MHz. In the latter case, the timings are CL19-21-21-41.
Cold metal
For more efficient heat dissipation, as well as for the sake of decor, the Viper 4 Blackout DDR4 modules are dressed in thick-walled aluminium heatsinks painted in night black. The height of the radiators is relatively small, so they should not interfere with the installation of even a large tower CPU cooler. But still this point should be considered before buying.
Beyond possibilities
Beneath the Viper 4 Blackout DDR4 heatsinks are hand-selected Samsung B-die memory chips. It is they that allow you to set the memory frequency of 4000 MHz, which until recently seemed sky-high, by simply activating the factory XMP profile. And manual overclocking can even achieve a frequency of 4233 MHz. But only on the latest Intel processors and motherboards. AMD computer platforms, for the most part, do not yet support even a frequency of 4000 MHz.
Backup plan
That is why the Viper 4 Blackout DDR4 has a second, alternative XMP profile — 3866 MHz with CL18-22-22-40 timings. Ryzen 3000-series processors and X570 motherboards can easily pull this frequency (check that the memory controller works in synchronous mode, otherwise the whole effect of high-frequency memory is leveled). Whereas owners of the Ryzen 2000-series are probably better off buying the Viper 4 Blackout DDR4 at 3600 MHz, and the first generation Ryzen at 3200 MHz. Fans of extreme overclocking are informed that Patriot has even higher frequency RAM: Viper RGB up to 4133 MHz and Viper Steel up to 4400 MHz.
