Crucial Ballistix 3600 MHz DDR4 DRAM Desktop Gaming Memory Kit 64GB (32GBx2) CL16 BL2K32G36C16U4B (BLACK)

Pros: Good no frills memory. Runs as expected at advertised speeds. 16-18-18-36 @ 1.35v. Very stable. Ran though several games and synthetic tests. MemTest86 ran multiples passes over several hours without error. Also ran AIDA64 stability test for memory with no issues.
While this is not low profile memory, it sits lower than my other G. Skill RipJaws V memory and allows the one DIMM slot under my cooler to be populated. This is an older Thermalright Ultra-120 Extreme that I've used for about 12 years in various systems. I've often only ever used 2 sticks of RAM in most systems, but most RAM is not short enough to fit under many air coolers in the last RAM slot. These indeed would fit, if the fan was temporarily removed.

Cons: None

Overall Review: Machine Specs:

Pros: Works at advertised speed

Cons: In this age of RAM speed dominating cpu performance, it is necessary for manufacturers to be more specific as to the exact specifications of their ram kits. Full timings, rank, and even ic type need to be specified to benefit consumers in choosing compatible kits. There is too much variation in a single sku.

Overall Review: Crucial is pulling a bait and switch by starting these kits as budget overclocking memory and switching them with lower performance chips. Full specifications on the kit are extremely difficult to find.
