Patriot Viper Venom RGB 7400 CL36 memory is the kit we will present today. It’s not the first DDR5 set from that company on guru3d. Almost a year ago, the Viper Venom 6200 CL40 was checked. The sample we’re reviewing is the best of the series. There’s also the Elite 5 (RGB/Non-RGB), which can achieve up to 7000 MHz and capacities of up to 96GB, and if you want the most performance, there’s Viper Extreme 5 series, where you can get even an 8000 MHz frequency memory (and the lowest available is 7600 MHz).


A quick reminder - DDR5 is the newest technology to hit the market, make headlines, and break world records. DDR5 already set spectacular results in overclocking (of course, using the LN2), as even 11154 MHz is achievable.  DDR4 RAMs operate on a single 64-bit bus, while DDR5 has two 32-bit buses (plus, in both cases, an additional 8-bit for ECC). As a result, a single module is identified as Dual Channel, while two are identified as Quad Channel. However, the solution does not match the throughput of HEDT platforms with processors with a four-channel controller. The internal (A / B) channels of DDR5 RAM also share the RCD (Register Clock Driver), which provides more output signals and more extended pulse reading (8 vs. 16). The DDR5 comes with a Power Management Integrated Circuit (PMIC) from the most important things you need to know. It’s responsible for controlling voltage changes, optimizing the energy draw, and making it less demanding for the motherboard controller. The DDR4 nominal voltage is 1.2 V; for the DDR5, it’s 1.1 V. Typical XMP voltage for the older type of memory is 1.35V (sometimes 1.4-1.45 V); now, it’s mostly 1.25 V. Speaking of the XMP, till now, it was 2.0 revision, with the introduction of the DDR5 we’ve got the rev 3.0. The main difference is that the number of profiles has increased from three to five (three for the manufacturer settings and two placeholders for the users).



After this short introduction – let’s present a bit of the review sample. There are no color variants. The Viper Venom DDR5 memory modules sport a two-tone exterior with a primary matte black design with brushed aluminum accents. The kit we got is equipped with RGB, so the LED enjoyers should be happy.


(Still – there’s a variant without the lighting). Our sample is the best frequency kit from the Patriot Viper Venom RGB series, with a 7400 MHz clock, CL36-44-44-110, at 1.45V. As for the capacities of this family, it’s 2x 8 GB (5200/5600 MHz non-RGB), 2 x 16 GB kit, and 2x32 GB (for 5600/6000/6400 MHz) available. As for the frequencies, there are the following variants available:

  • 5200 MHz
  • 5600 MHz
  • 6000 MHz
  • 6200 MHz
  • 6400 MHz
  • 6600 MHz
  • 6800 MHz
  • 7000 MHz
  • 7200 MHz
  • 7400 MHz (the one shown here)

Overall, this Patriot Viper Venom RGB memory kit seems like a good option for those looking for high-capacity, high-speed memory with RGB lighting (but there’s an option not to have it). It’s a series with an XMP profile. The height of the memory module is 43 mm/1.69 inches, so it’s not a low-profile form, which can cause rare problems with the (air) CPU coolers. As for (official) compatibility – there should be no problem with the AMD (up to 6000 MHz) and the Intel platform (at least for variants with frequencies up to 6400-6600 MHz, the higher frequency kits need the Z790 chipset).


We’ll check the kit on two platforms, with Z790-based motherboards (Asus Z790 Maximus Hero) combined with the Intel Core i9 13900K and the Asrock X670E Steel Legend combined with an AMD Ryzen 9 7900X. The used GPU is the Nvidia Geforce RTX 4090, so it shouldn’t be a limiting factor for memory performance. We are traditionally going to try and squeeze something more out of it. The default parameters and visual aspects look attractive – we must check the performance then. A limited lifetime warranty backs the Patriot Viper Venom RGB series. Ok, next page, please.
