Patriot has expanded its memory offerings for enthusiasts with a brand-new family of products, the Viper 4 Blackout. The new lineup supports data transfer rates of up to 4000 MT/s and is tested for compatibility with AMD’s latest Ryzen 3000/X570 desktop platform.

Equipped with matte black aluminum heat spreaders, Patriot’s Viper 4 Blackout memory will be available as 8GB and 16 GB dual-channel kits rated to operate in DDR4-3000 CL16, DDR4-3200 CL16, DDR4-3600 CL17, and DDR4-4000 CL19 modes at 1.35 Volts.

Patriot’s Viper 4 Blackout memory modules use a custom 10-layer black PCB to guarantee great signal integrity, but the company does not disclose which chips it uses for its new DIMMs. Meanwhile, by default the modules come with a standard DDR4-2133 JEDEC profile, but they feature XMP 2.0 profiles to automatically set the aforementioned tested speed-bins.

One thing to note about the Viper 4 Blackout products is that Patriot specifically decided to offer devices for those who want an all-black system. Therefore, the memory modules come without any RGB LEDs, something that opposes today’s 'RGB everywhere' trend.

Patriot’s Viper 4 Blackout DIMMs are backed by a lifetime warranty and will be available shortly at $51.99 - $184.99 price points depending on exact kit models.

    not the best option, because tcd <10ns
  • FreckledTrout - Thursday, July 11, 2019 - link

    Can you elaborate?
  • Dug - Thursday, July 11, 2019 - link

    No RGB? Sign me up.

    Yeah! Really nice to see memory without rpg! Just hoping for a Little bit better timings and larger memory size...

    But how will I level up my performance and enchant my motherboard if it's not an RPG?

    Add as many stickers as possible - works great to triple horse power and improve handling for cars ;)

    Kudos to Patriot for being one of few companies to not foist off silly RGB lighting onto people uninterested in buying it. I hope they sell really well and encourage the company to continue to leave RGB out.

    Would not you need to radically slow down the internal Ryzen bus (IF) to 1:2 instead of 1:1 if you run memory over 3200? After all, the buses are not really decoupled.
  • ballsystemlord - Thursday, July 11, 2019 - link

    Its unclear if the IF slows down, or the RAM to IF link slows down, the difference being that instead of the the core to core communication slowing down, along with the IF-from-RAM to core communication, instead the core to core communication speed remains the same whereas the RAM to IF link has higher latency and the IF-from-RAM is just as fast as core to core communication.

    However, what's more important is that if the RAM can run at 4000 then you can down clock to 3733 (IIRC) and then you'd have the best of both worlds.

    The whole IF slows down for 2:1, not some IF 2 RAM. There are no registers in between.
