The same as the previously reviewed Ballistix MAX 32GB DDR4-4400, the MAX RGB DDR4-4000 memory uses single-rank modules. Each module has 16GB capacity and is based on the Micron B IC. It’s the only single-rank memory series that uses single rank 16GB memory modules. It provides a wide range of possible settings from DDR4-3600 CL14 up to DDR4-5000+ CL18. We actually tested these settings on two different memory kits.
Below is more detailed info about memory modules. As we can see, thermal sensors are also available.
If you are searching for the best Micron IC, you can find it in Ballistix memory kits. As the manufacturer says, Ballistix optimizes performance at the die level, instead of only binning as all other brands do.
Our memory kit has one XMP profile, programmed to run at DDR4-4000 CL18-19-19 and 1.35V. As you find out later, this is already a great setting and can be overclocked much more. Right now, let’s focus on the XMP profile. Below is the stability test at declared settings. There are no problems at all.
As long as we are lucky few users, who have Ryzen 5000 processor with a robust memory controller and infinity fabric that runs at a 1:1 ratio at DDR4-4000, then the XMP will be optimal for everything. When we are less lucky, we may lower the memory clock, keeping full stability and not much lower performance. For modern Intel chipsets, DDR4-4000 will be optimal and won’t be limited in any way. However, AMD is more popular in the last few months, so we will also use it for our tests.
Before tests, let’s take a closer look at the package and its contents.
