Question Is there a big performance difference between Kingston hyperX furry and valueRam?

ValueRAM's KVR24N17S8/8 is programmed to run at latency DDR4-2400 timing of 17-17-17 at 1.2V.

HyperX HX424C15FB2/8 is programed to run at DDR4-2400 at a low latency timing of 15-15-15 at 1.2V

Memory timings describe the performance of memory using several parameters. These parameters specify the latencies (time delays) that affect speed of memory Lower numbers usually imply faster performance. What determines absolute system performance is actual latency time, usually measured in nanoseconds.
