This program has many tools for determining memory bandwidth as well as various latency values.
In our AIDA64 read test, clocking our RAM a bit higher improves performance by a significant margin. We see a result of 56,399MB/s at DDR4 3733MHz and 48,401MB/s at DDR4 3200MHz.
One might easily conclude that the memory values were switched by accident. However, this isn’t the case. Due to the differences in GEAR modes, raising the frequency of the memory with the controller being clocked less in GEAR 2 makes this difference. The 1:1 ratio is only maintained in GEAR 1 mode.
Our DDR4 3733MHz configuration only managed 43,007MB/s compared to 45,917MHz at stock speeds due to the GEAR mode differences. You could force it at 1:1.
Sandra Memory Bandwidth
It’s no surprise that our overclocked memory configuration achieved better results than our stock setup did. However, it’s interesting that the delta between almost all of these results is relatively small.
