Patriot has recently released their latest memory series, the brand new Viper LED. As you can guess by the name these modules will feature LED lighting. While not RGB you have the option to choose from Red or White illumination. The modules have a new heatspreader design, which I have to say is one of the best we’ve seen from Patriot. The kit will will be taking a look at today is the PVLR416G300C5K which is a Viper Red LED Series kit of 2 x 8GB modules (16GB total) running at 3000 MHz with timings of 15-17-17-35 at 1.35V. Let’s get this kit in our test system and see what it can do!
Capacity: 16GB (2 x 8GB)
Tested Frequency: PC4-24000 (3000 MHz)
Tested Timings: 15-17-17-35
Pin Out: 288-pin
Warranty: Limited Lifetime Warranty
The Viper LED kit comes in a nice retail package with a picture of the kit on the front and a sticker in the top right that lets us know the capacity and speed.
Flipping over to the back there is a short paragraph in a handful of different languages explaining the kit. Also on the back we see that we do get a lifetime warranty.
Getting everything out of the package we have the two memory modules and a couple of Viper stickers.
Patriot Viper LED DDR4-3000 16GB Memory Kit Overview
Taking a first look at the kit the thing that really stood out to me was the new heatspreaders. They are all black with some grey designs on each side and a Patriot Viper logo right in the center. These are probably some of the best-looking modules we’ve seen from Patriot. To match the black heatspreader we have an all-black PCB as well.
If you missed it, this is the PVLR416G300C5K which is a Viper Red LED Series kit of 2 x 8GB modules (16GB total) running at 3000 MHz with timings of 15-17-17-35 at 1.35V. If you flip the modules over you have a sticker that gives you all of that information.
At the top of each module you of course have the light bar, which acts as a diffuser for the red LEDs that sit below it. On the light bar there is a Viper logo.
With the light bar at the top the modules are a bit larger than a normal DDR4 modules, but not overly-larger. Officially these modules are 1.75-inches (4.44cm) tall, so make sure you keep that in mind.
When you install the Viper LED kit in your system and power it on you’ll notice the light bar at the top of the modules light up. As we mentioned Patriot offers these kits in red or white versions, we have the red version.
The light bar does a good job at diffusing the red LEDs that are beneath it, but there are very noticeable “dead spots” in the light bar. It seems as if Patriot should had added three more LEDs on the top of the module. These effect is very noticeable when you look at the modules from the side, when you are looking straight on it is not as noticeable.
The brightness of the light bar seems just about right as it is not overly bright or too dim. These LEDs are static so they are on at all times. There is no way to turn them off or do any effects. If you do have other red components in your system they are going to look really good matched with this memory.
Overclocking on the Intel Z370 platform is pretty easy. The easiest way to overclock would be up simply change the frequency divider in the BIOS. To achieve the best overclock we try to stay with the timings that the XMP profile recommends. If we run into any issues we will bump up the voltage to see if we can get our system to boot and become stable.
The XMP profile puts this kit at 3000 MHz. In the BIOS I started moving up the frequency divider. So we went from 3000 MHz, to 3066 MHz, and then to 3200 MHz.
At 3200 without touching the timings or anything our system was completely stable. When we went up to 3333 MHz the system would boot, but did not pass our stability test. So I decided to bump up the voltage little by little to achieve a stable system. I ended up at 1.4520V.
So our final stable overclock at the XMP timings of 15-17-17-35 is 3333 MHz, which is a 333 MHz overclock over the default 3000 MHz! Not bad at all!
We installed the Viper LED DDR4-3000 16GB Memory Kit in our Z370 test system which is made up of the following components.
Processor: Intel Core i7-8700K
Graphics Card: MSI GeForce GTX 1060 Gaming X 3GB
Motherboard: ASUS Prime Z370-A
Memory: Patriot Viper LED DDR4-3000 16GB
Storage: Zotac Premium Edition 240GB
Power: Corsair AX860i
Cooling: NZXT Kraken X52
Case: Lian Li PC-T80
Taking a look at CPU-Z we can see this memory is running at its XMP profile, operating at 3000 MHz with timings of 15-17-17-35 at 1.35V.
For testing we will run the memory at its stock or XMP profile settings using the below benchmarking software. We will then run the tests again our overclock of 3333 MHz. Below is a list of benchmarking software that we use.
– SiSoftware Sandra Memory Bandwidth Benchmark
– SiSoftware Sandra Cache & Memory Latency Benchmark
– SiSoftware Cache Bandwidth Benchmark
– AIDA64 Cache & Memory Benchmark
– Cinebench R15 Multi-threaded test
– 3DMark Fire Strike Physics test
Now let’s get to testing!
To start things off we have SiSoftware’s Sandra. The first test is the Memory Bandwidth benchmark. Higher scores are better here.
Next we have Sandra’s Cache & Memory Latency benchmark that will measure the memory kits latency. Lower scores are better here.
Our final Sandra test is the Cache bandwidth test. Higher scores are better here.
AIDA64 has a built in Cache & Memory benchmark that measures read, write, copy and memory latency. For the read, write and copy higher scores are better, for latency lower scores are better.
Next up is Cinebench R15. This benchmark renders a photo-realistic 3D scene. All of the rendering is done by the CPU, although changing memory and memory speeds does make a difference. We ran the multi-threaded test, higher scores are better here.
Finally we wrap things up with 3DMark’s Fire Strike benchmark. We will be taking the Physics score from our benchmark as it will change the most when you change memory speed. Again, higher scores are better here.
So how does this DDR4 compare to all other DDR4 memory kits that we have tested so far?
The Viper LED is Patriot’s first DDR4 memory kit with LED lighting and they did a pretty good job on the kit, but it is not perfect. PC lighting has become extremely popular and is very important to many people who are building their own systems. Adding any sort of lighting to memory modules is a good thing, but Patriot’s implementation here is not the best we’ve seen. While the red LEDs look good there are “dead” spots in the light bar that are very noticeable, especially when you are looking at them from the side. Other light implementations like the G.Skill Tident Z RGB and GeIL Super Luce are much better.
Another thing that is missing here is control software. You cannot adjust the brightness of the LEDs or turn them off. And there are no effects either like flashing or breathing.
Besides those issues this is a really great kit. The design of the heatspreaders is probably the best we’ve seen from Patriot, especially compared to their other DDR4 offerings. The overall performance at the XMP profile timings of 15-17-17-35 are comparable with other kits, but you can find DDR4-3000 kits with tighter timings out there.
One thing I was really impressed with was the overclocking headroom. We were able to run this kit at 3200 MHz without changing anything at all except the memory frequency of course! So basically we had a 3200 MHz kit right off the bat. Even better is with a slight voltage bump we were able to get the kit up to 3333 MHz, again at the same timings.
Right now the kit we reviewed today (PVLR416G300C5K) is selling for $194.99 at our favorite online retailer. That price is good, although you could pick up a GeIL Super LUCE RGB kit for $30 more, or a G.Skill Trident Z RGB kit for $40 more. Overall ThinkComputers gives the Patriot Viper LED DDR4-3000 16GB Memory Kit an 8 out of 10 score.
– One of the best looking kits we’ve seen from Patriot
– Great overall performance
– Priced accordingly
– Lots of overclocking headroom
– Light bar has “dead spots”
– No way to control the lighting
