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.

- 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.
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.

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.
