When buying computer or laptop RAM (memory), it’s important to consider several key factors to ensure compatibility, performance and value for money. DDR3,DDR4

1. Compatibility with Motherboard
  • RAM Type: Check if your system supports DDR3, DDR4 or DDR5. Each generation is physically and electrically different.
  • Form Factor:
    • Desktop PCs use DIMM modules.
    • Laptops use SO-DIMM modules (smaller size).
  • Maximum Capacity: Verify your motherboard’s maximum RAM capacity per slot and total.
2. Speed (Frequency) of computer or laptop RAM (memory)
  • Measured in MHz (e.g., 2666MHz, 3200MHz, 4800MHz).
  • Higher speed generally means better performance, but your CPU and motherboard must support it.
  • Laptop and desktop users should check the system manual or manufacturer’s website for supported speeds.
3. Capacity (Size)
  • Common sizes: 4GB, 8GB, 16GB, 32GB, 64GB, etc.
  • Usage guide:
    • 4GB: Basic tasks (not recommended for modern systems).
    • 8GB: General use, office, web, streaming.
    • 16GB: Gaming, multitasking, light creative work.
    • 32GB+: Heavy graphics design, video editing, virtualization, or gaming enthusiasts.
4. Dual Channel / Multi-Channel Support
  • Using two identical RAM sticks (e.g., 2×8GB) enables dual-channel mode, which doubles data bandwidth and boosts performance.
  • Always match speed, size, and brand for best results.
5. Latency and Timings
  • Lower latency (e.g., CL16) = faster response time.
  • Important for gamers and power users, but for most people, capacity and speed matter more.
6. Reliability of computer or laptop RAM (memory)
  • Check for warranty and after-sales support, especially in Kenya.
7. Heat Spreaders or Cooling
  • Some high-performance RAMs come with heat spreaders for cooling.
  • Useful in gaming PCs or high-performance desktops, less necessary for laptops.
8. Price and Availability
  • Balance your budget with performance needs.
  • Prices vary depending on generation (DDR4  vs DDR4 vs DDR5) and speed.
  • In Kenya, prices can differ significantly between new and refurbished RAM.
9. Future Upgrade Possibility
  • Leave extra slots or plan for future upgrades.
  • Example: Use 1×16GB instead of 2×8GB if you plan to expand to 32GB later.
10. Vendor Credibility
  • Buy from trusted suppliers like Takashi Computers, where you get genuine and tested RAM compatible with your device.
