Performance
Beyond the memory kits included in the table above I also added results with the Team Xtreem memory overclocked to 1400MHz ( DDR3-2800 ).
SuperPi 32M
SuperPi is benchmark popular especially among overclockers. It’s known to react to memory speed so it’s good to compare memory performance.
As we see here, the performance difference with Core i7 3770K 4.5GHz isn’t as big as expected. Higher CPU clock will help for sure but at least at this point it’s hard to see noticeable difference between 2133/2400 kits running with tighter timings and 2666/2800 kits running at looser timings.
AIDA64
AIDA64 Cache and Memory benchmark is great tool to check memory transfers and not only. We can also check CPU’s cache bandwidth or access time but we will focus on RAM transfers that are showing differences in RAM settings.
As we see on above graph there is almost no difference above DDR3-2400 mark. Both G.Skill and Team Group kits are limited by memory controller speed.
MaxxMem v1.99
MaxxMem is next memory bandwidth benchmark which is also showing memory read, write and copy transfers.
Much like the other tests we are limited with memory controller here, so all results at DDR3-2400 or higher are nearly the same. It’s just another reason why so fast memory is dedicated mainly for overclockers. It’s just hard to notice any difference without higher CPU overclocking.
