Closer Look: Patriot Sector 5

Most high performance memory modules include some type of heatsink and the Patriot Sector 5 kit is no exception. It features the same aluminum heatspreaders as the rest of the Viper II line, albeit with a different logo. At 1.65v, these heatspreaders are plenty adequate to deal with any heat the modules produce and look pretty good too. My only concern is that the fins may interfere with some CPU coolers and motherboard layouts. I suppose it's a trade off for increased surface area and dissipation capacity.


Also worth noting is that kit we received from Patriot is an engineering sample. Compared to the final retail version, there is a slight variation in the programming of the SPD. As you can see in the CPU-Z screenshot above, the XMP profile for this kit is set to 8-8-8-26 timings instead of 8-8-8-24. Despite the variation we decided to use the SPD settings as is. We were more interested in how the XMP profile would adjust the settings needed to reach 2000MHz. Because the multiplier of the Core i7-870 in our test bed cannot exceed 12, the system bus had to be increased from 133MHz to 166MHz. Selecting the XMP profile on our ASUS P7P55D EVO did this automatically, while also reducing the CPU multiplier to 18 to ensure it would not be unintentionally overclocked.


As you can see in the screenshot above, the Northbridge frequency, also connected to the system bus, was overclocked as well. The XMP profile took care of just about everything, but I would suggest one more thing: turn off Turbo Boost. Even though the base multiplier of the CPU was reduced, I found that the CPU would try to throttle up to 27, resulting in a CPU frequency of roughly 4500MHz. While this is a great overclock, if you aren't prepared for it with adequate voltage and cooling, it can result in stability issues.
