RAM Memory


Perhaps the easiest and most cost-effective way to give your computer a boost is adding more memory. Desktops, laptops, notebooks and servers all see a dramatic increase in performance with more memory added. Shop RAM upgrades at Doctor Memory.

Different RAM

We now have DDR3, DDR4 and DDR5 memory available to buy. No matter if you’re putting together a gaming PC or upgrading your current system, we have the memory you need.

RAM Memory Working

RAM is a component of your computer that allows for short-term data access. Since your system’s moment-to-moment operations rely on short-term data access — loading applications, browsing the web, editing a spreadsheet, or playing the latest games — the speed and amount of memory installed plays a critical role in your system’s performance.

DDR4 RAM Memory

RAM is part of your computer that enables its to be read and written processes. Because your computer’s moment-to-moment operations are more likely to rely on a few core processes and RAM is easily accessed much quicker than the data storage, even if you have an abundance of RAM, your programs would be stored on the SSD for higher performance.

  • DDR4 RAM types: UDIMM, RDIMM, and LRDIMM
  • Capacities: 4GB to 64GB
  • Speeds: Up to 3200MHz
  • Compatible with Intel and AMD platforms

DDR3 RAM Memory

DDR3 memory remains popular for older systems and offers a budget-friendly upgrade. Great for office machines, business computers and general home use.

  • DDR3 RAM types: UDIMM, RDIMM, and LRDIMM
  • Capacities: 2GB to 64GB
  • Speeds: Up to 2400MHz
  • Excellent value for money

Laptop RAM Memory

Upgrade your portable computing power with laptop RAM. Perfect for students, professionals, and anyone on the go.

  • Capacities: 2GB to 32GB
  • SO-DIMM form factor
  • Improves multitasking and performance

Gaming RAM Memory

Gaming RAM is designed for high-performance systems. Achieve faster load times, higher frame rates, and an overall smoother gaming experience.

  • DDR4 and DDR5 gaming memory options
  • Capacities: 8GB to 32GB
  • Speeds: 3000MHz and above

Computer Memory FAQ's

Dr Memory (Doctor Memory) pioneered the UK DRAM market and has been supplying high-performance PC components, peripherals, and gaming PCs for over 12 years. We specialise in premium PC RAM for UK gamers and enthusiasts.
We provide high-quality, reliable RAM at competitive prices through rigorous testing, efficient supply chains, and a commitment to sustainability.
Computer memory (RAM) acts as your system’s short-term brain, storing data your CPU needs for quick access. This keeps applications running smoothly and efficiently. Installing RAM is straightforward—usually just a screwdriver is needed to open your PC.

Choosing the right type—DDR4 or high-speed DDR5—can improve boot times, multitasking, gaming performance, and creative workloads.
  • 8GB: Browsing, office tasks.
  • 16–32GB: Gaming, video editing, multitasking.
  • 48–64GB+: High-end creative software or AAA gaming.
  • 96GB+: Power users, data analysts, or workstation setups.
Always check your system’s maximum supported RAM before upgrading.
Laptops: Use SO-DIMM modules. Match DDR type (DDR3, DDR4, DDR5), speed, and voltage.
Desktops: Use DIMM modules. Check motherboard specs for DDR type, capacity, and slots. Matched pairs (e.g., 2 × 8GB) optimise dual-channel performance.
DDR5: Latest standard, higher bandwidth, better power efficiency, speeds from 4800MHz+, ideal for future-proofing and high-performance systems.
DDR4: Reliable and widely compatible, speeds up to 3600MHz, cost-effective, perfect for most modern builds.
DIMM (288-pin): Standard desktop memory with higher capacities and better heat dissipation.
SO-DIMM (262-pin): Compact laptop modules, common for DDR4 and DDR5. Correct form factor ensures proper installation and performance.
Gaming RAM features higher speeds, lower latency, and extras like heat spreaders or RGB lighting. It ensures stability and performance during intensive gaming sessions.
  • 16GB: Solid baseline for most games.
  • 32GB: Ideal for streaming, multitasking, or heavily modded games.
  • Competitive players: Faster RAM speeds can give an edge.
Not always. Higher speeds can help in gaming and creative tasks, but CPU/motherboard compatibility, latency, and cost also matter.
Servers often use ECC RAM and registered (RDIMM) or load-reduced (LRDIMM) modules for stability and larger capacities. Check your server manual for supported type, rank, speed, and capacity. Matching modules ensures reliability.
We buy in volume, use efficient supply chains, and rigorously test all modules for performance and reliability, backed by strong warranties.
