Memory Kit Specifications / Comparison

Initial Setup

As we get into the overclocking section later on in this review, it becomes apparent why a XOC overclocking oriented motherboard is best paired with this memory. Pictured here we have the ASUS Z790 APEX paired with the Patriot Viper Xtreme 5 RGB memory kit. While Patriot only offers this Viper Xtreme with a black heatspreader, it doesn't look all that out of place here. The integrated lighting could be improved as the individual LEDs are easily identifiable. Though, some may take the stance that having nice RGB aesthetics isn't the primary attraction to the Viper Xtreme 5 series.

Enabling XMP Profile

The Patriot Viper Xtreme 5 8000 MT/s memory kit had no stability issues during the testing phase. However, a quick reminder that compatibility will greatly depend on the motherboard OEM. From testing various motherboards, it is advised to only use this memory with select Intel Z790 based motherboard and an Intel 13th Generation (K) Processor. This is because Z690 motherboards are not validated to supported 8000 MT/s by the motherboard manufacturer. In fact, only two Z690 candidates are likely to achieve this frequency without resorting to XOC tactics; Gigabyte Z690 Tachyon and EVGA Z690 Dark.

Using a 12th Generation (K) Processor is out of the question. Besides using exotic cooling and going well beyond daily safe voltages for the CPU, 12th Gen is not a option. This is because the Intel 12th Gen CPU internal memory controller (IMC) limitation lands anywhere between 6800 MT/s and 7400 MT/s using voltages that are good for daily usage. Many a Z790 motherboard can also be problematic as well, and it suggested to only use 2-DIMM motherboards like ASUS Z790 Apex, Gigabyte Z790 Tachyon or EVGA Z790 Dark when targeting 8000 MT/s and above.

Upcoming 14th Generation (K) Processors and Intel Z790 (MAX) refresh may have greater headroom, but until they are officially released to the public, only leaked information can give us a glimpse of what is to come. As always, for best results, it is always suggested to seek out the motherboard manufacturer's memory QVL list.
