Sandra is a software collection of synthetic benchmarks that will give us a basic idea as to what a system is capable of. It should be noted that SiSoft numbers change depending on what hardware is being tested. These were recorded using Sandra Professional Version 30.29.2020.5
AIDA64 Extreme Edition is a streamlined diagnostic and benchmarking software package designed to assist with overclocking and general system tuning. The package also contains modules to assess the performance of the processor, system memory, and disk drives in addition to normal stuff like stress testing and troubleshooting.
PCMark 10 is an overall system benchmark to measure and compare PC performance using real-world tasks and applications. Similar to 3DMark this new version tests the entire system as a whole using applications that reflect typical PC use in the home and at the office. This approach ensures that PCMark measures the things that matter, highlighting performance differences that will be apparent to end users and consumers.
As expected once the secondary SODIMM module was installed we got considerably more bandwidth and slightly better application performance. While the Patriot Viper Steel Performance Memory Module has the potential for running at 3000Mhz my ProBook cannot take advantage of that and is left running at 2400Mhz.
What I find interesting is how the memory latency jumped once the Viper Steel module was installed and I know from experience when you install mismatched memory modules the system will train to whichever is slowest.
Overall I cannot deny that having more memory does increase performance and even though the modules are mismatched, installing them both really did less harm than good.
