Decoding a RAM Stick: 2GB 1Rx8 PC3-10600S-9-11-B2
Ever wondered what all those numbers on a RAM stick mean? Let’s break down this label:
· 2GB – Total capacity of the module.
· 1Rx8 – “1R” = single rank; “x8” = 8 memory chips per rank, each 8 bits wide (so 1 rank × 8 chips × 8 bits = 64-bit data bus).
· PC3 – DDR3 memory (PC3 = DDR3, PC4 = DDR4, etc.).
· 10600 – Peak bandwidth in MB/s (≈ 10.6 GB/s). This equals DDR3-1333 (1333 MHz × 8 bytes = 10,664 MB/s).
· S – SODIMM form factor (laptop memory). Desktop DIMMs usually omit this or use “U”.
· 9 – CAS latency (CL9).
· 11 – tRCD and tRP timings (11 cycles each).
· B2 – Manufacturer-specific revision/stepping code (varies by brand; not a standard spec).
Quick summary: This is a 2GB DDR3-1333 SODIMM for laptops, single-rank, with CL9 timings. It’s an older module — common in systems from around 2008–2013.
