To get the most out of these new Memonex TOP Series modules, they will be put through a series of benchmarks designed to see how well they perform under load. With the set having lower power requirements, I am curious as to how well they will stand up among other sets designed for raw speed. They will be compared to other sets of memory designed for the Intel Socket LGA 1156 platform. The CPU is run at a clock speed of 200 x 16 on the Patriot modules, while the balance of the modules are run with the CPU at 160 x 20 for the 1600MHz rated kits and 133x20 for the 1333MHz rated modules using a memory multiplier of 10 to keep the modules at their rated 1333MHz, 1600MHz and 2000MHz speeds. For the overclocking test, I will use a combination of voltages and timing increases, while increasing the base clock on the CPU, to increase the clock speed of the modules to see if they are capable of reaching higher speeds to deliver additional performance.

The Memonex TOP modules are a set of 1333MHz modules rated to run at latencies of 8-9-9-18 using 1.5 volts. The lower voltage specification gave me some hope of reaching the higher clock speeds than the G.Skill Eco modules did, but the Memonex modules did not want to play with the big dogs on the top end and topped out at 1660MHz. Increasing the vdimm and ancillary voltages higher or lower coupled with additional loosening of the secondary timings failed to yield any more clock speed. I could boot into Windows at up to 1700MHz, but in no way was it stable for anything but a super Pi run. While just over 1600MHz seems like a poor increase, if you put the amount of the increase into perspective, you get a 327MHz (163MHz) bump in clock speed for your efforts, which is really nothing to sneeze at - I have had modules give up less headroom and cost more. On a percentage basis, this increase in clock speed is a 25% increase that shows up as a 20+% increase in the memory bandwidth scores in Sandra, as you'll see later on.
