What is interesting, under the stickers we will find Micron C9BHF. What is so interesting ? Most Micron memory chips are marked as D9xxx. I can’t even find description of this IC on the Micron website while it’s clearly in mass sales as our review sample is typical, retail product.

Memory modules are single rank what usually gives hope on better overclocking so exactly what we are looking for. On the other hand Micron is known of not the best overclocking memory so we don’t really know what to expect ( well, I already know but you have to wait 🙂 ).

Programmed XMP profile works withou issues. Motherboard runs with memory at DDR4-2400 16-16-16 using auto settings and at DDR4-2666 16-18-18 using XMP profile. Exactly as we expected.

Below is screenshot which is showing memory stability after nearly 9 hours of full memory load in quad channel mode at XMP settings.


Package and Closer Look

The Ballistix Sport LT comes in a typical blister package which is the most popular package type for memory modules and many other components.

Our memory wasn’t designed as quad channel kit and each memory module was packed separately. However, all of modules with the same product number supposed to be based on the same IC. In this case, as I already mentioned, it’s Micron IC what is the most typical and expected considering that Crucial and Ballistix are Micron brands.

On the memory modules are stickers which look like think heatsinks. DDR4 memory is not heating up much so heatsinks are not really required. Even while overclocking additional cooling is not really required. Typical temperature of modules is below 50°C under heavy load while maximum operating temperature is about 80°C so it’s perfectly safe.

SODIMM modules are designed to work in laptops so how memory looks like doesn’t really matter. In our case memory will work on a desktop motherboard where more users care about the looks. The Sport LT modules look quite good. Black PCB with gunmetal grey/silver stickers should fit to most builds. Our motherboard is black so it’s a perfect match.

Since I mentioned the motherboard then here are couple of words about it.

What is even more interesting is what this motherboard has to offer. Three M.2 sockets with VROC support, six SATA ports with RAID, two LAN ports, WiFi, Bluetooth, USB 3.1 and much more. What is the most interesting for me is the fact that this motherboard supports SODIMM DDR4 in quad channel mode. Actually I wonder why isn’t it memory standard for desktops. Capacity is similar, performance is similar but modules are smaller.

Above are couple of more photos of the test rig which also contains the i9-7900X processor and EVGA GTX1080Ti graphics card.

One would wonder if it’s possible to build small PC using these components as under full load it may pass 600W. I guess this will be my next challenge.

Right now let’s focus what we can achieve with the Ballistix Sport LT DDR4-2666 on the ASRock X299E-ITX/AC. Our results are on the next pages of this review.
