Samsung 2GB DDR3 Laptop RAM 204-Pin SO-DIMM PC3-8500S 1066MHz (M471B2873CH1-CF8)Technical Description Module Type: 204-Pin SO-DIMM (Laptop / Small Form Factor DDR3) Module Capacity: 2 Gigabytes (2GB) Brand: Samsung Part Number: M471B2873CH1-CF8 (V055) Memory Speed: DDR3-1066 / PC3-8500S (1066MHz clock speed) Timing Profile: 7-10-F2 (CL7 Latency) Configuration: Dual-sided, Dual-Rank (2Rx8), Unbuffered, Non-ECC, 1.5V standard operating voltage. Onboard Components: 8x Samsung K4B1G0846F high-density FBGA memory chips (4 per side). Compatibility: A key upgrade module for high-end laptops, netbooks, and Apple MacBooks from the 2008 to 2010 era. The dual-rank (2Rx8) high-density layout is highly prized because many early legacy DDR3 laptop chipsets (like the Intel Mobile 4 Series or first-generation Core i3/i5 mobile systems) strictly require low-density, dual-rank memory architectures to boot and will fail to recognize modern single-sided memory sticks.Seller Note: Sold as a single individual laptop module. Images show both front and back chip configurations. Clear factory Samsung label. Clean gold contact pads with zero structural scoring. Item is sold in used, un-tested condition.
