Closer Look

The Viper LED 16GB DDR4 is a dual module kit i.e 2x8GB. As the name indicates there is a LED diffusor on the top and it is in white LED. Here is what Viper has to say about their Elite series kits, “Patriot Viper LED series memory modules are designed with true performance in mind. Built and tested for the latest platforms, the Viper LED series not only provides the best performance and stability but also adds some flair for the most demanding gaming PC environments. The design concept of the LED series’ heat shield is to highlight Viper and its line of professional high-speed gaming. This high-quality aluminum heatshield also offers superior heat dissipation to ensure rock solid performance even when using the most taxing applications. Our Viper LED series offers the most competitive and aggressive specifications as it is the highest segment of Patriot OC DRAM product lines. The Viper LED series are available in either red or white LED color.”

 

Our kit has two modules with the capacity of each being 8GB. The base timings of the kit are 15-15-15-36 with a base frequency of PC4-17000(2133MHz) at 1.20V. The rated timings are 16-18-18-36 with the frequency of PC4 28800 (3600MHz) at 1.35V. It is Non-ECC, Unbuffered DIMM with a 288-pin layout (DDR4). It has black color aluminum heat spreader with LED diffusor at the top. It is tested for Intel and AMD platforms for reliability and compatibility and is XMP 2.0 ready. The kit has a black PCB. The heat spreader is pasted on the PCB using an adhesive tape. The Viper is utilizing the Samsung ICs in this kit. The height of the module is 45mm making it sitting between High Profile to Low Profile kits. Length of the module is 135mm and depth is 0.7mm. The aluminum-based heat spreader on both sides is in black color. It has ribbed Viper brand logo in the middle of each side and texture in the gray color is on the left and the right sides of this logo. This unique design makes the kit stand out and looks stunning in person. At the top on each side, there is a cutout on both ends in an angled horizontal layout. There are 7 angled cutouts in a vertical layout on the top where the heat spreader is protruding towards the LED diffuser. These cutouts are aligned with the angled cutouts on the LED diffusor at the top. This not only makes the design symmetrical but also makes it look stunning and pleasant. The terminating ends of the spreaders towards the RAM’s pin have curved ends though this is not apparently visible with a quick look. The heat spreaders are not superimposed as we saw on the Elite series DDR4 kit that we have reviewed earlier. The heat spreaders are facing point to point with each other. The other side of the kit has a white color sticker pasted on the right side facing the RAM. The part no of the RAM is printed on its top left side. It goes like PVLW416G360C6K. If I am to decode this part no, it would be like Patriot Viper LED White DDR4 16GB 3600MHz C16 and Black. By now, I believe this is self-explanatory information. There is Patriot’s P logo in the blue color on the top right side of this sticker. Warranty on the kit would void if this sticker is removed.

Overall look and feel of the kit is premium and finishing on it top notch with build quality speaks for itself. There is an LED diffusor in the white color on the top separating both the heat spreaders. This diffusor has white color LEDs underneath it. I am not sure how many LEDs are there in it. The Viper brand name is printed in the black color on the flat surface side of the diffuser. The cutout design on half of the diffusor gives this kit the bold and aggressive looks. Once the kit lights up we can see that though the lighting is consistent across the length there are shadows in brown/black colors at various points of the diffuser. The lighting is not overly done and they are bright enough to give pleasant look. Please, not that there is no software control should you want to control the brightness and there is no color effect either. It will light up in the static white color or red color depending on the type of the kit.

 

Testing

We have tested this drive on the X99 platform. The test bench setup is as follow:

  • Intel i7 6850k
  • Asus Rampage V Edition 10
  • Noctua NH-U14S
  • Samsung 840 EVO 250GB SSD
  • Seagate 2TB Barracuda
  • Colorful iGame GTX 1050Ti
  • Corsair AX1200i

We have used the AIDA64 Extreme and SiSoftware Sandra suite to test the performance of the kit. We have tested the kit at JDEC’s default specification of 2133MHz, with XMP and then with the overclocking. The CPU Strap and BCLK were set to 100 for the 2133MHz and XMP testing. For overclocking the kit the BCLK of 125 was used and CPU Strap was set to 125 as well. With XMP, the DRAM timings and Voltages were verified as per the manufacturer’s rated specification. We have used BIOS version of 1703 on the Asus motherboard. The Asus motherboard on the test bench supports maximum frequency of 3333MHz (OC). Despite various attempts to overclock the kit beyond the 3600MHz was a pure waste. Trying with 167 BCLK and CPU Strap was also futile and so was the case with the high voltages for the DRAM and the CPU to compensate for it. We were just able to push it a little bit above the rated frequency. 3735MHz was the overclocked frequency with mere 135MHz over the rated frequency of 3600MHz. This is coming due to the platform limitation more than the Memory’s own limitation or silicon but we should keep in mind that this kit is already highly overclocked out of the factory with the XMP 2.0 as the JDEC specifications are 2133MHz and 2400MHz for the DDR4. Anything above is not guaranteed by either party. The RAM was overclocked with the 1.450V DRAM voltage. We did not experiment with it more as the item was supposed to be returned after completion of the review.  The 3735MHz overclocked frequency was tuned with the same timings 16-18-18-36 CR2. Our attempts to fine-tune the timings on the 3600MHz was a failure as well. The other kits in the testing are the Corsair Vengeance 1x8GB DDR4 @ 2666MHz and Viper Elite 8GB DDR4 @ 2400MHz. Let’s take a look at the results.

We ran the AIDA64 on all above-described frequencies which are 2133MHz, rated 3600MHz and overclocked 3735MHz. With XMP the read speed was 45488MB/s, Write speed was 36479MB/s and copy speed of 42127MB/s. This is a performance right on the money given the comparison with the other kits in the graph. With overclocking the read speed was 46132MB/s which is a 1.41% performance gain over the rated frequency. 44100MB/s was the Copy speed with overclocking, representing 4.68% performance gain over the rated frequency. 37780MB/s was the write speed with overclocking representing the 3.56% performance gain. The latency value comes to 56.5 ns with XMP 2.0. It was reduced to 54.3 ns with overclocking. This is 3.89% improvement.

Next, we ran the SiSoftware Sandra suite to check the memory bandwidth using the Multi-Threading and Single-Threading options. With XMP 2.0 loaded, 18.46GB/s was the aggregate memory performance in single threaded mode and 37.23GB/s aggregate memory performance in multi-threading. With overclocking, there was 19.76GB/s aggregate memory performance which is 7.04% improvement on a single threaded performance. Aggregate Memory performance was 38.43GB/s under Multi-Threaded mode with overclocking which is 3.22% performance gain. Next, we ran the SiSoftware Sandra Latency test. 22.1ns was the tested latency at 3600MHz which was reduced to 21.3ns with overclocked memory.

This kit is listed at Rs.27,800/- at the time of the review. With current price fiasco of the DRAM, it is hard to evaluate the value proposition of the given RAM at hand. But this price is just right for this kit as competitive offerings like Corsair Vengeance LPX with 3200MHz frequency and C16 is listed at Rs.27500/-whereas the GSkill Ripjaws  V 16GB kit at 3200MHz and C16 is listed at Rs.26900/- This pricing has made the Viper LED 16GB DDR4 kit to stand out the competition and has our praise for it. Our kit has performed very well on the test bench. Unfortunately, we got stuck in overclocking this kit on our X99 platform.
