Patriot Viper RGB 16GB DDR4-4133 Memory Kit Review

Patriot was one of those household names back in the days where they’d usually hold their own neck-to-neck against other top-tier brands. Fast forward to modern times and they’ve been focusing on other things but they never forgot who they are. Patriot has been a performance brand and their Viper line has been the pinnacle of performance for the RAM department. Its seen various forms over the years but today sees perhaps the most defined change in Patriot Viper history. Today we take a look at the Patriot Viper RGB DDR4 sticks.

The Patriot Viper RGB RAM comes in speeds from DDR4-2666 all the way to DDR4-4133. The memories come in kits of two 8GB sticks. They come in both black and white heatsink. White versions are available up to DDR4-3200. The sample we have for you for today is their flagship Patriot Viper RGB DDR4-4133 16GB dual-channel kit with product code PVR416G413C9K.

The Patrior Viper RGB RAM kits are tested for both Intel and AMD systems so there’s no choosing which kit to go for when running on any system. Let’s take a closer look and see how the Patriot Viper RGB DDR4 performs.

Patriot Viper RGB RAM Unboxing

Closer Look

Here we have a shot of the packaging: full colored print cardboard with a shot of the product in the front. The Patriot Viper RGB comes in both white and black heatsink so we’re curious if the white version white packaging. Regardless, a shot of the product is in the front with a large sticker denoting model. The Viper RGB is printed on the bottom as well more Viper/Gamer inspired prints at the back.

Inside we have a thermoformed clamshell holding the memory. We also get instruction sheet and some Viper logo stickers.

Looking at it from the side, the Viper RGB has a mid-standard height but each stick is quite maxed out in terms of thickness. The heatsink features a Viper logo down the middle without much other to note.

Here’s a show of the kit installed. Notice how they lean against each other already when installed in standard DIMM slots with standard spacing. The middle light bar are stacked while the edge light bars that protrude upwards have a bit of wiggle room.

Light Up

Here’s a comparison of the light bar from the Viper RGB versus the Corsair Vengeance RGB Pro. While its subjective, the lightbar on the Viper RGB sticks are much thicker and give off a brighter glow.

Stock Patriot Viper RGB DDR4-4133

Normally, we’d go with a lower stock speed like the DDR4-3200s or -3600s which have excellent OC headroom. This time around we have a DDR4-4133 kit. There are some kits out there that can do DDR4-4400 or -4500 right now but those are few and far between. For Patriot, DDR4-4133 is peak performance. We get 19-21-21-41 timing out of the box and since this is the first time we’re reviewing anything outside of DDR4-4000, we really don’t have much experience. While we elected to tighten timings, our kit is seems to hit a wall already, dropping to CL18-19-19-40 but comparing with other kits, Patriot seems pretty tight with their default timings already. Still, we wanted to see if we could eek out more.

Note that latency is loonie already in this bench. We have another run for the latency for the benchmarks.

Now we want to see how far we can take this kit and the Patriot Viper RGB DDR4-4133 seems like they’re tightly binned already. We could push the kit to DDR4-4266 with 20-22-22-43 timings but anything memory intensive and it just crashes. It managed to finish some benches but was overall unstable for any use. We’ll leave the results for reference data only. Do note that we do not voltage on any OC attempts for the simple reason that outside of competitive OC, the stock XMP voltage is plenty enough for us.

Note: SuperPI 32M did not finish on the OC settings

As you can see, at this speeds there’s really only a slight increase in overall performance but basing on pure numbers, the memory bandwidth difference from DDR4-3200 to DDR4-4133 is significant for some apps and we’ll talk about that in the conclusion. Overall, the benchmark give us close numbers but shows the Patriot Viper RGB can still hang on top.


Should you not have an RGB-compatible motherboard for whatever reason, Patriot has a dedicated software for their Viper RGB memory. They are insistent that this software be used standalone, so we highly advise using your motherboard RGB controller should it have one. If it does not, then this software is good enough. It does have some light effects selection as heatsink color selection for display purposes. You can configure up to 5 profiles with this software but other than its really as basic as it gets and we suggest Patriot improve the UX of this software as its really lacking.


As established already, there’s really no need for breakneck speed memory in the 4000s to game. Still, right now memory prices are dropping and since launch, we’ve seen this kit reach past $200 but are now around $179. Again, price scales with speed and capacity with memory and while we recommend around DDR4-3000 to DDR4-3200 in general, those who have a mix bag of use-case scenario that can benefit from faster memory may be able to justify to relative increase in cost without the need to fiddle around with the silicon lottery on lower speed kits. The Patriot Viper RGB DDR4-4133 brings the speed out of the box and its RGB is quite a looker itself.

Pricing may be Patriot’s best friend in this time as nearly 6 months ago, RAM prices are so steep but right now you can get a sweet deal for a high-performance kit like the Patriot Viper RGB for so much less. With cost out of the way, that ultimately leaves you, the buyer, to decide if you really need the maximum speed that this kit offers. Otherwise, Patriot still offers the Viper RGB in speeds from 2666 to 3600 which are nearly identical in prices on retail right now.

That said, for RGB hunters the kit offers solid performance already so if you’re after solely for the light, Patriot has thick lightbar on this things. The lightbar are a hit or miss so if you’re digging it, go ahead.

Ultimately, the Patriot Viper RGB line of memory kits is something we’d highly recommend for anyone looking for a decent RGB kit for their new build offering great value for endusers right now.

Patriot backs the Viper RGB DDR4 memory with a limited lifetime warranty. We give it our B2G Silver Award and B2G Best Value Award!
