Kingston KVR48S40BS6-8

This is an 8 GB DDR5 SODIMM memory module for laptops and compact PCs, running at 4800 MT/s (PC5‑38400) with a CAS latency of CL40. It uses a single‑rank (1R x16), 262‑pin SO‑DIMM design and operates at 1.1 V, making it more power‑efficient than typical DDR4 modules. The module supports On‑Die ECC, is non‑ECC, unbuffered, and built with gold contact fingers for reliable connectivity. It’s a straightforward, industry‑standard memory upgrade — ideal for boosting RAM in compatible laptops or small‑form-factor systems needing a stable 8 GB DDR5 stick.

This RAM module is best suited for someone who:

• Uses a laptop for everyday tasks, browsing, office work, light‑to‑moderate multitasking
• Wants a quick performance boost or upgrade without spending much — maybe upgrading an entry‑level or aging laptop
• Uses integrated graphics or doesn’t require high‑end GPU workloads
• Needs stable, power‑efficient RAM (good for battery‑powered laptops)

Specifications

• Capacity: 8 GB
• Type: DDR5‑4800 (PC5‑38400 / PC5‑4800)
• Form Factor: 262‑pin SODIMM (for laptops / compact PCs)
• CAS Latency: CL40 (timings: 40‑39‑39)
• Voltage: 1.1 V — typical DDR5 efficiency compared to older DDR generations.
• Rank: Single‑Rank (1Rx16)
• Error Checking: Non‑ECC (standard for most consumer laptops)
• Module configuration: 1Rx16 (single‑rank)
• Data rate / Speed: 4800 MT/s (effective) — roughly 2400 MHz clock rate.
• Operating temperature: 0 °C to +85 °C
• DRAM density / chip organization: 16 Gbit chips, x16 organization

Key Features

• Memory Type & Capacity: 8 GB DDR5 SODIMM (1 G × 64‑bit) — suitable for modern laptops or small form‑factor systems.
• Speed / Bandwidth: 4800 MT/s (PC5‑38400) — much faster than standard DDR4 modules.
• CAS Latency (CL): CL40 (timings typically 40‑39‑39 at 1.1 V) — the latency rating for DDR5‑4800 operation.
• Voltage: 1.1 V (with DDR5 standard power supply voltages: VDD = VDDQ = 1.1 V) — more power-efficient compared to many DDR4 modules (~1.2V).
• Form Factor / Pin‑out: 262‑pin SODIMM — designed for laptops and notebook‑class devices.
• Rank & Organization: Single‑rank (1R x16) with DRAM chips organized as 1G ×16‑bit FBGA components.
• On‑Die ECC (Error Detection): Internally uses ECC for data integrity, though the module is non‑ECC / unbuffered externally — this gives better reliability without requiring motherboard-level ECC support.
• Compliance & Physical Build: Gold contact fingers; RoHS compliant and halogen-free PCB; standard SODIMM dimensions (approx. 30.00 mm height).
• Operating Conditions: Rated for typical laptop operating temperature range (0 °C to +85 °C), storage temperature down to –55 °C up to +100 °C.
• Compatibility & Use‑Case: Built for notebooks/laptops and compact systems that support DDR5‑4800 SODIMM — widely used in modern Intel/AMD-based portable PCs

What it’s good for

• It’s suited for laptops or small form‑factor PCs that support DDR5 SODIMM — a straightforward upgrade if your notebook uses DDR5.
• DDR5‑4800 gives higher bandwidth and energy efficiency compared to DDR4, which can help with multitasking, content creation, coding, moderate gaming, etc.
• As an 8 GB module, it’s a good base or a sensible budget‑friendly upgrade — often works well combined with another stick for dual‑channel.

⚠️ What to check before buying

• Your laptop or motherboard must support DDR5 SODIMM 262‑pin — DDR4 or desktop DDR5 modules will not be compatible.

• For heavy workloads (e.g. heavy video editing, VMs, large datasets), 8 GB might be limiting — pairing two modules or going for 16 GB+ could be better long‑term.

• Because latency is CL40, it’s standard vs. high‑performance DDR5, so one shouldn’t expect enthusiast‑level latency — but for most consumer use‑cases it’s perfectly adequate.

Good Scenarios for This RAM

• Everyday laptops & general productivity — If you use your laptop for web browsing, document editing, spreadsheets, email, streaming, office apps, etc., this 8 GB DDR5 module provides a smooth, responsive experience and helps avoid slowdowns. Upgrading to DDR5 also yields faster memory bandwidth vs older DDR4 modules.

• Multitasking / moderate multitasking workloads — Running multiple browser tabs, background apps (e.g. messaging, cloud sync, antivirus), light photo editing, or general multitasking benefits from extra RAM. The 4800 MT/s speed helps the system juggle memory‑intensive tasks more fluidly.

• Laptops with integrated graphics or shared‑memory GPUs — On systems without a dedicated GPU, the system RAM is shared between CPU and GPU. More/faster RAM helps avoid performance bottlenecks when handling graphics, video, or mixed workloads.

• Light to moderate gaming / casual gaming laptops — For games that don’t demand lots of RAM (or rely more on GPU), having 8 GB DDR5 helps reduce stutters, speed up loading, and improve overall system responsiveness.

• Budget‑conscious users wanting a stable upgrade — If you just want a reliable memory boost without overspending — for example, upgrading an older laptop to keep it usable for everyday tasks — this module offers good value: DDR5 performance, low voltage (1.1 V) for efficiency, and reliable build quality.
