Top critical review
Does not peform as well as previous Ballistix Sport kit

I don't like how Amazon is lumping together reviews of different products by the same manufacturer. It ignores how different these products actually are. I'm reviewing the Ballistix Sport LT 8GB Kit (4GBx2) DDR4 2400 (BLS2K4G4D240FSB (Gray)). This kit was a bit of a disappointment compared to a similar kit I bought a few months ago. The previously purchased memory was also a Ballistix Sport LT 8GB Kit (4GBx2) DDR4 2400, but it had the white heat spreaders (BLS2K4G4D240FSC), instead of the gray. The first kit proved to be capable of easily running at DDR 3066 MHz speed, using 16-16-16-39 timings. This current kit, which I am reviewing now, barely can barely reach 3066 MHz. It requires relaxing the timings to 16-18-18-39 and using more voltage than the previous kit required in order to achieve this speed. Because the chips are covered by heat spreaders, which are probably attached with adhesive thermal tape, I cannot say if there is a difference in the chips being used or whether this is due to some variation in manufacturing quality of the chips.
I am now running both kits together on an Asrock X370 PRO4 motherboard with an Ryzen 5 2600. I was unable to run the four modules together at 3066 MHz, but they do seem to be stable at 2933 MHz with 16-18-18-18-39-55-CR=1T timings (the sub-timings are the Auto timings for this speed) and 1.35 volts.
Bottom line is that there is nothing wrong with these chips, but they seem relatively ordinary, especially compared to the first set that I bought.
PS: Both kits are identified as Single Rank Modules by CPU-Z and HWiNFO64.
