Crucial Ballistix Tactical 32GB DDR4 4x 8GB DDR4-2666 Review

Characteristics and other features …

Recently we’ve tested a Crucial Ballistix Sport 16GB DDR4 Kit consisting of 4x 4 GB DDR4-2400 modules. Crucial Ballistix Tactical DDR4 memory modules are designed for higher speeds and faster timings according to Crucial as, for example, the Crucial Ballistix Sport DDR4 modules. According to the Web site to beat to it sooner, faster, and more often than your opponent. Later we will see, how the Crucial Ballistix Tactical vs Sport beats in comparison.

Heatspreader …

Two thin heat sinks (heat spreader) were affixed on the memory modules, which provide a lower temperature of the memory modules, even at some higher voltages and higher clock rates. Last but not least the attached double-sided heatspreaders offers a little protection. Thus, one achieve better OC results and receives a longer lifetime.

Crucial by the way grants lifelong warranty (Limited Lifetime Warranty) to the purchaser, all information about manufacturer conditions are of course without guarantee by


Officially the modules are designed with the JEDEC standard for 1.20 Volts DDR4 voltage to reach the CL16 timings at DDR4-2400 easily without errors.

However to achieve DDR4-2666, a manual adjustment in BIOS is either necessary, or you load these values from the Intel XMP 2.0 profile. Because the fast timings and frequencies were as XMP-2666 (Intel Extreme Memory Profile) stored in the modules on an EEPROM and can be detected by many motherboards similar like the common SPD (Serial Presence Detect) value for the standard timings.

After loading the XMP settings, the modules are correctly shown in the UEFI.

Here you can see the read of SPD and XMP in the UEFI Setup of the ASRock motherboard:

Less than 32GB during boot, only 3GB in the BIOS or less than 32GB in Windows …

It can occur that the memory capacity is only showing up 3GB instead of the 32GB, because 32GB RAM or any sizes with more than 2GB have to be adjusted in the BIOS and/or in the OS. Here is a RAM guide which contains among other things a table, how much RAM each OS can support. Additionally there are some topics in our forum in hints and cheat, how one can address 4GB, 8GB, 16GB or more also with 32-Bit operating systems.
