Not only does the Crucial Ballistix Sport DDR4-2400 quad channel kit utilize 1.2 V but it was also able to outperform DDR3 clocked 400Mhz higher. When overclocked to 2933Mhz we get an outstanding increase in copy and read performance which offers a very significant boost in performance. Oddly enough write performance remained the same even with a overclock, I ran each test multiple times at multiple configurations and little to no change was observed. Last year’s top of the line system was left in the dust in terms of memory performance, another nail in the coffin for DDR3’s reign in the mainstream market.

As generations of DDR arrive there is always a signficant performance boost when compared to a previous generation, one aspect where performance actually dwindles is Column Access Strobe Latency or CAS Latency. In short, CAS Latency is the time it take a memory controller to interact with memory module and this latency increased in DDR4 due to jump in bandwidth. So how badly affected is the CAS Latency for the Crucial Ballistix Sport DDR4-2400 ? Take a look for yourself, at stock speeds only using the X.M.P profile we see a pretty significant CAS Latency of 67.1 ns which is significantly high when compared to DDR3 as expected. Looking at the overclocked Crucial Ballistix Sport DDR4-2400 we see a significant improvement in CAS latency that even beats the DDR3 CAS delay.

Lastly, we will go to the SiSoftware Sandra benchmark which is another all-in-one tool capable of testing virtually every part of the machine. We are going to focus on two tests in particular though, memory bandwidth and latency. With SiSandra’s different testing methods we see a combined score of 56.38 GB/s on the overclocked Crucial Ballistix Sport DDR4-2400, a noticable boost over stock speeds and significantly ahead of its DDR3 counterpart.

Again, similar to Aids 64 we see the Crucial Ballistix Sport DDR4-2400 struggle a bit against DDR3 in the latency benchmark. Luckily any drawbacks are overcomed by overclocking.
