Crucial Ballistix 16GB (2x8GB) DDR4-4000 CL18 Red

Discontinued low-profile (39mm) gaming DDR4 — the massive seller of the AM4 / LGA 1200 era. Sought after used for its exceptional Micron E-die overclocking headroom. Kit: 16GB (2x8GB) DDR4 at 4000 MHz, CAS latency CL18. Finish: Red. Form factor: 288-pin DIMM (desktop). 100% genuine Micron DRAM. Rated speed requires enabling XMP 2.0 in BIOS; the kit boots at JEDEC 2133 MHz until you do. Seller note: the model number prefix tells you the tier — BL is the discontinued Ballistix gaming line (strong enthusiast resale), CP is the modern Crucial Pro series, CT is standard/OEM JEDEC memory. Legacy Ballistix kits with Micron Rev. E or Rev. B silicon are the ones overclockers hunt for; the exact die revision is verified before this listing goes active.
