For performance testing, I ran through a few of my preferred memory benchmarks. My favorite is AIDA64’s memory and cache benchmark. In that test, I focused on the read, write, copy, and latency tests. I ran this same test on the Kingston HyperX Predator 3000Mhz kit that we run in our test bench normally as a baseline. Then I ran all of our tests again on both Sport LT kits at XMP speeds and again with each kits max overclock speed. This brought a few interesting results. As you can see below, both kits responded very well with their overclocks, for example, the 2x32gb Sport LT kit saw a read speed improvement of just over 14%. The write speeds on that same overclock were a little less stellar, I think that overclock was pushing the limits at that voltage a little too much. The 2x16 kit was actually faster when overclocked. The latency results were even better though, the overclocks showed a big improvement over the stock speeds. When comparing the Sport LT to the HyperX kit, the 3200MHz clocks on both put the 2x26 kit on par and had the 2x32gb kit above the HyperX kit.





In Cinebench R15, this isn’t a memory specific benchmark. I just wanted to take a look at how the different memory capacities and speeds might change the CPU performance in both single and multi-CPU configurations. The overclocked 32gb kit showed that you can push too far, but the 16gb kit showed that you can see a big improvement with an overclock. The same goes for bumping up from the 16gb kit to 32gb kit at XMP speeds.


In Passmark’s Performance Test 9 I ran the full ram benchmark to get the overall Memory Mark score. Here the overclocked 32gb kit really pulled ahead. This benchmark does favor higher memory capacities to a point, that is why the 16GB kit didn’t do as well. But look at the Predator results compared to the 32gb Sport LT kit. Their memory threaded test did especially well when overclocked.


Lastly, I went to a classic, MaxxMEM² is a memory benchmark that overclockers like to run. I ran all three results and it is a similar benchmark to what AIDA64 runs. Here the overclocks made for less of a difference, it favors timings more than clock speeds.




While overclock testing the 32GB kit at 3800MHz I did do an AIDA64 memory stress test and get a few thermal shots. With the exception of the warm spot on the right side of the side, the memory ran especially cool. Most of the heat was coming out the top, not out of the heatspreaders.
