Memory is often hard to separate from one kit to another in gaming, but when it comes to number crunching and computing, some memory provides an extra boost in comparison. To see just what kind of performance this kit has to offer, I will be running the modules through a series of benches to see just how they compare. There will be 8GB, 16GB and 32GB kits ranging in speed from 1866MHz - 2400MHz, tested at native speeds as well as overclocked. Overclocking of course will be dependent on exactly how far the testing rig will allow, but I'll push it as far as I can. The testing setup used for these benchmarks is listed below, where Turbo Boost has been disabled to eliminate uncontrolled clock changes that may skew the results. The CPU will be run with default clock speeds for baseline testing and bumped up to 4.5 GHz or as close as possible to the speed where possible for OC testing. All current updates and patches are installed for Windows 7 Professional 64-bit and the current AMD Catalyst driver of 12.6 is used for the video card.

Overclocking the Mushkin 997070 and 994071 kits was dependent on what the modules and CPU would allow. Starting with the 994071 32GB Redline Ridgeback modules, I was able to push this quad pack kit up to an impressive 2202MHz or 336MHz (18+%) over its rated speed. To get to this clock speed I used a combination of tweaking the memory timings and applied voltages to the modules and memory controller. The defined memory ratios are hard jumps in speed with 2133, 2200, and 2400 as the options available in the BIOS on the M5G. 2400MHz would boot with 1.75v but would not pass Memtest test eight even with 13-13-13 timings so at best it would be a suicide screenshot-only speed. Reaching 2202MHz required running the bclock to 103.2 using the 2133MHz divider and manually tweaking the TRFC to 283, loosening the timings to 11-12-12-28 2T, and pushing 1.665v to the modules with 1.08v to the memory controller. Higher voltages or looser timings did not offer significant increases or added stability. I would have thought that I could reach a much higher clock speed with the 16GB 997070 kit than I did. I used the same methods used with the 32GB kits to reach 2288MHz using roughly the same voltages and timings with the 16GB 997070 kit running tighter timings at a higher MHz. This kit still would give me the same issues reaching 2400MHz so I stayed with the 422MHz increase on this Redline 16GB kit. Any which way you cut it these modules deliver speed with reasonable timings. Tighter timings can be run with additional voltage applied at the baseline speeds if that is the way you want to go. The trend of getting more seems to be holding true with these modules, especially with the ability to run at 9-9-9-28 using 1.65v.

The maximum memory speed for each set of overclocked modules is indicative of how well the modules ran on this test system. As such, your results may differ in either a positive or negative way based on the capabilities of your hardware. In other words, your mileage may vary!
