Do you (like myself) miss the snappy feel of the DDR2 tight timing RAM of the previous generation of computers? I know when I switched to the P55/i7 platform that I now have, it just didn't feel as snappy as the computer I was replacing. I found a couple of ways to bring back the snappy feel I was so used to. First was the addition of an SSD and the second was higher frequency DDR3 RAM. You would think that going from DDR2-1066 RAM to DDR3-1600 RAM would only serve to increase the performance and feel of your computing experience, but I found it lacking that good 'ol "snappy feel". Raising the RAM frequency at or above the 2000 Mhz boundary seemed to bring back the quickness and my enjoyment of my computer once again.

Today we are taking a look at a set of DDR3-2000 RAM from Patriot Memory, namely the Viper Xtreme 4 GB set. This particular set of memory runs at a guaranteed frequency of 2000 Mhz at timings of 9-10-9-27 at 1.65v. This memory sports an extruded aluminum medium rise heat spreader with the addition of a copper strip (6 grams per module) to facilitate thermal transfer between the memory modules and the aluminum heat spreader. Patriot has stated that this design will result in a 5% better thermal profile than standard aluminum-only heat spreaders.


Closer Look:

The memory arrived in an outer box with an inner retail clam shell container securely holding the RAM. The outer box just gives you the name, picture and states a few facts about the particular RAM, like "Designed for Intel P55 Platforms", "Unrivaled Performance", "Free Technical Support" and Patriot's contact information with an address, phone number and email address. The inner clam shell gets a little more specific and gives the exact kit details.










Here you can see the retail clam shell packaging that holds the RAM modules securely in place.


Here we see the actual RAM modules themselves. You can clearly see the copper strips through the cut-outs in the extruded aluminum heat spreaders. The heat spreaders protrude just shy of 1/2" (approx. 12mm) above the memory's PCB.



Let's take a look at how this memory performs.

Testing of the Patriot Viper Xtreme memory will include all the standard OCC tests. We will run this memory at the rated frequency and timings specified by Patriot Memory, make sure that the XMP profile works as expected and finally, push the RAM to see what headroom is available for the overclockers out there without getting carried away with either the voltages or loosening the timings too much.


Testing Setup:

Comparison Modules:


CPU-Z: This application shows us the settings that we have chosen in the BIOS. Items shown in this application include CPU speed and bus settings, motherboard manufacturer, BIOS revisions, memory timings and SPD chip information.



Task Manager: We use this utility to show physical memory, kernel memory, page file and processor usage.




Overclocked Settings:


The Patriot Viper Extreme memory managed an increase of its frequency to 2112 Mhz with only a slight bump in the tRCD timing from 10 to 11. The memory ran completely stable at this elevated frequency and proved to boost the performance of this set of RAM in our testing.





The maximum memory speed for each set of modules when overclocked is a measure of how well the modules ran on these particular settings and test system. As such, your results may differ in either a positive or negative way based on the capabilities of your hardware. Meaning, that your mileage may vary!

The benchmarks used in this review include the following:



PCMark Vantage: With this benchmark, I will be running the system suite, as well as the memory test suite. The measurement for the system suite will be the total score. The measurement for memory performance is the total memory score.

SiSoftware Sandra 2011: In this program, I will be running the following benchmarks: Cache and Memory, Memory Bandwidth and Memory Latency. Higher is better in all tests, except for Memory Latency, where lower is better.

The Mushkin Radioactive took all of the overclocked tests here because of its higher overclocked frequency versus the Patriot Viper Xtreme. Except for that, the Patriot performed well in the testing.


Geekbench 2.1 provides a comprehensive set of benchmarks engineered to quickly and accurately measure processor and memory performance. Designed to make benchmarks easy to run and easy to understand, Geekbench takes the guesswork out of producing robust and reliable benchmark results.

Super Pi Mod 1.5 is a program designed to calculate Pi up to the 32nd millionth digit after the decimal and is used as both a benchmarking utility and simple stress test to check your overclock before moving forward with more rigorous testing. The world records for this benchmark utility are hotly contested.

Here also, the Patriot Viper Xtreme memory does very well in the testing.


Batman Arkham Asylum is a game that pits Batman against the Joker who has taken control of Arkham Asylum along with a whole load of bad guy prisoners. His task is to rescue various hostages the Joker takes, along with trying to stop the Joker himself and fighting scores of prisoners in the interim.

Here we see that all the memory tested was about on-par with each other, give or take a few FPS.


The Patriot Viper Xtreme memory performed well in the testing even with the little available overclocking headroom. The addition of the copper strips between the memory modules and the extruded aluminum heat spreaders is a nice addition to help keep the heat down in these memory modules. This design improves on the AOC concept used on the original Viper Series modules. The cool running modules help bring stability to higher end overclocks. When overclocked, I was able to push Viper Xtreme modules up another 112MHz. Not earth shattering but worth the effort to get them to this level.

Like I stated in the introduction, the higher frequency memory modules do make a difference in the feel of your computer (at least it does to me). I for one, like the snappy feel of my computer that the higher frequency RAM gives me. Thus investing a little more in a guaranteed higher frequency kit like this, may also be worth it for others if you feel the same as I do. This set of modules is made for the enthusiast and it shows with enhanced cooling and latencies to give you that 2000MHz + set of memory you are looking for .
