Patriot Viper Fin Extreme Latency PC2 6400 Review

Price: $TBA


As DDR2 system memory has matured, the latencies that the modules run at have gotten tighter and tighter to reach levels that the enthusiast community look for to increase system performance. That is the name of the game isn't it? When DDR2 was introduced just a short two years ago, latencies ran as high as 6-6-6 but now, through ever improving modules, 3-3-3-or 3-4-3 are possible. It may take some additional voltage up and away from the JEDEC spec 1.8 volts to make it happen but that is what warranties are for aren't they? With the decrease in latency, a boost in performance is the expectation that the end user has. If that expectation is not there then why even bother with performance memory? For many, the benefits will not be realized since they are not in the know and good ole' generic system memory will work. For those that understand the benefits of decreased latency, this would be the sytem memory for you.

The Patriot Viper Fin PC2 6400 2 x 1 GB set of modules are one set of Xtreme latency modules. These recently introduced modules are designed to run at latencies of 3-4-3-8 at DDR2 400 speeds using 2.3 volts. While 2.3 volts may seem high for everyday use, these modules were designed to run at this voltage specification and even carry a warranty. Will the specially designed ACC (Aluminum Copper Cpmposite) heatspreaders be enough to keep these modules cool under fire from 2.3 volts? Only time and testing will reveal the answer to this question.

Closer Look:

The Patriot Viper Fin PC26400 comes in a clamshell enclosure with the modules securely locked in place. Included in the package is a quick start and installation guide to help with the installation.



The PC2 6400 modules are labeled as Xtreme Latency modules. Manufactured to run at 3-4-3-8 latencies at DDR2 400 speeds at 2.3 volts. The specially designed heatspeaders denote this set as part of the Viper Fin series of high performance modules.



The Viper Fin series of modules use a uniquely designed heatspreader to dissipate the heat load generated by 2.3 volts on the system memory. The heatspreader uses a design that Patriot calls ACC (Aluminum Copper Composite). This design uses a copper inner layer that contacts the modules to wisk away the heat to the aluminum outer layer that features many rdges to effectively increase the surface area of the heatspreader. This makes the design more efficient at dealing with the heat load.
