How to Choose the Right Kit
Follow this decision tree:
- Step 1: Determine DDR4 or DDR5 — check your motherboard/laptop model
- Step 2: Determine form factor — DIMM (desktop) or SODIMM (laptop)
- Step 3: Check how many free slots you have
- Step 4: Choose capacity — 16GB minimum for general use, 32GB for power users
- Step 5: For DDR4, 3200MHz CL16 is the sweet spot. For DDR5, 5600MHz is standard
- Step 6: Always buy a matched kit (2 modules) rather than individual modules for dual channel

Frequently Asked Questions
Is cheap RAM reliable?
Budget RAM from reputable brands (Kingston, Crucial, Corsair, TeamGroup, G.Skill) is perfectly reliable with lifetime warranties. Avoid no-name brands from marketplace sellers. The main difference from premium kits is speed/timing, not reliability.
Should I buy the cheapest DDR4 or spend more on DDR5?
If your system uses DDR4, buy DDR4. You cannot switch without a new motherboard and CPU. If building new, DDR5 is worth the modest premium for the upgrade path. For existing systems, spend on capacity rather than a platform change.
Can I mix my old RAM with new RAM?
Possible but not ideal. Matching capacity and speed is important. If you have one 8GB-3200MHz module and add another 8GB-3200MHz module, it will likely work. But for guaranteed compatibility, buying a matched kit is always safer.
Where is the cheapest place to buy RAM in the UK?
Amazon UK typically has the best prices with easy returns. Check price comparison sites like PriceSpy or CamelCamelCamel. CCL Computers, Scan, and Overclockers UK also offer competitive pricing with knowledgeable support.
