Benchmarking the Patriot Memory

Test Setup:

In this section we will show the setup of the test system for our memory testing.  The G2 memory comes with SPD timings of 1218MHz at CL8, 1370Mhz at CL9 and 1522MHz at CL10 - all at 1.5v.  The XMP profile is locked down at 1600MHz at 9-9-9-24-38 2T.  This is not very aggressive and it caused me some concern as to how much overclocking headroom this kit actually has.  In the end we benchmarked the kit at three different settings: Stock, Stock speed with CL8 timings and Stock timings at 1866Mhz.

The Viper Extreme kit comes with SPD timings of 1066MHz at CL7, 1218MHz at CL8 and 1370Mhz at CL9 - again, all at 1.5v.  The XMP profile on this memory is locked in at 1866MHz at 9-11-9-27-50 1T.  This should give better performance than the other kit as the Command Rate of 1T is twice as fast as the DDR3-1600 G2 kit mentioned above.  With that being said, we still hit a wall right around 1950MHz on this kit so we tested at two speeds: Stock and Stock timing at 1953MHz.  In order to achieve the 1953MHz speed, we had to overclock the CPU slightly and ran the system at 33x104.8MHz = 3.46Ghz - up from the stock 3.3GHz.

On the next page we fire up the system and put this memory to the test at stock CPU speeds - except for the DDR31953Mhz settings - so you can see just how much actually memory speed affects performance.
