RAM Memory Kingston KVR26N19S6/4 4 GB DDR4 2666 MHz CL19

4 GB DDR4. 2666 MHz. CL19. 1.2V. 288-pin DIMM. Green/Black. No Backlight. Halogen-Free. RoHS. Windows, Linux & macOS Compatible. The Kingston KVR26N19S6/4 for Desktop PC and Server.

The Kingston KVR26N19S6/4 is a 4 GB DDR4 SDRAM 288-pin DIMM module operating at 2666 MHz with CL19 latency and 1.2V standard DDR4 voltage in a Green and Black 133.3 mm form factor without backlight. RoHS certified and halogen-free. Compatible with Windows, Linux and macOS on Desktop PC and Server platforms. Sold as 1 x 4 GB single module. No XMP configuration required — JEDEC DDR4-2666 standard speed from first boot on any compatible 288-pin DIMM slot.

4 GB DDR4 SDRAM + 2666 MHz + CL19 + 1.2V + 288-pin DIMM + Halogen-Free RoHS: The Six Kingston KVR26N19S6/4 Specifications That Define Its Capacity, Speed, Compatibility and Environmental Certification.

The 4 GB DDR4 SDRAM capacity at 2666 MHz delivers the memory bandwidth and capacity that Desktop PC and Server platforms running Windows, Linux or macOS require for standard multitasking, productivity workloads and server process handling — the 2666 MHz DDR4 speed being the JEDEC-validated standard frequency that Intel LGA 1151/1200 and AMD AM4 desktop platforms accept from the first boot without frequency configuration, XMP activation or manual timing entry. The CL19 JEDEC latency at 1.2V represents the DDR4-2666 standard column access strobe latency at standard DDR4 operating voltage — 1.2V being the DDR4 specification voltage that requires no voltage modification on any compatible DDR4 motherboard and that keeps the module within the power and thermal envelope that compact desktop and server chassis impose on installed memory. The 288-pin DIMM form factor at 133.3 mm fits the standard desktop and server DIMM slot that all DDR4-compatible motherboards provide — the 288-pin keyed connector preventing incorrect orientation and ensuring positive electrical contact across all signal lines on insertion. The halogen-free and RoHS certified construction confirms the KVR26N19S6/4 meets EU RoHS hazardous substance restrictions and uses halogen-free flame retardants in the PCB and component materials — the environmental certifications that procurement specifications for PC and Server deployments in regulated industries require. The no-backlight Green and Black design integrates the module into desktop and server builds where RGB lighting is not specified and memory slot visibility matters more than aesthetic lighting output.
