Hi friends!
I get asked this a lot, so I figured I’d share it with the community 🙂
With the current AM5 RAM shortages at the consumer level, a lot of people are building AM4 systems again — and honestly, I love this. AM4 is still very viable, and most people do not need an AM5 system for daily use or gaming.
This is a simplification, but it’s a really solid rule to follow: when buying RAM — and it applies to both AM4 amd AM5
RAM setup matters more than people realize
For example:
Someone bought a system with 4×8GB sticks for a total of 32GB of RAM.
👉 This is actually the slowest configuration for most consumer systems.
When all four RAM slots are filled, AM4 systems usually won’t run at their advertised speeds, even if XMP/EXPO is enabled in the BIOS. The system often falls back to standard JEDEC speeds instead.
This setup is great for productivity workloads (Blender, rendering, heavy multitasking).
But it’s not ideal for gaming or daily use.
If gaming or everyday use is your goal, you want only two RAM slots populated, specifically A2 and B2.
( When counting slots starting from the CPU side, you want slot 1 empty, slot 2 populated, slot 3 empty, alot 4 populated).
This applies to both AMD and Intel systems.
👉 16GB in two slots with XMP/EXPO enabled will often outperform 32GB spread across all four slots.
If you want 32GB, get it as 2×16GB sticks, not four sticks.
What to look for:
Higher MT/s (memory speed)
Lower CL timings (latency)
A good example for AM4:
3600 MT/s
CL16–19–19–36
Quick way to think about it:
Lower MT/s (3400 / 3200) = slower communication with the CPU
Higher CL numbers (17 / 18 / 19+) = slower response between the RAM sticks
If you’re buying RAM second-hand:
Ask for a photo or video of both sticks installed and working together
Ask for a clear photo of the stickers on both sticks
(This shows MT/s, CL timings, and kit part numbers)
Why this matters: A lot of people are splitting RAM kits right now because of shortages. Others then try to buy single sticks and combine them into a “kit” — and later find out it doesn’t work properly - this shows up in Failure to Boot , or Random Crashes.
Even if two sticks have the same part number, that does not guarantee they’ll work together.
RAM kits are intentionally matched at the factory based on silicon quality and electrical characteristics.
This process is called "binning".
Final step (don’t skip this)
After installing new RAM:
Go into BIOS
Enable XMP (Intel) or EXPO (AMD)
Otherwise, you’re leaving performance on the table.
