Know these cold
- RAM is volatile — it loses all data when power is removed.
- DDR5 uses a 32-bit bus per channel (vs DDR4's 64-bit), doubles bandwidth, and has on-die ECC.
- Dual-channel: matching DIMMs in alternating slots (e.g., slots 2+4) doubles memory bandwidth.
- SO-DIMM is the compact laptop form factor — shorter than standard desktop DIMMs.
- ECC RAM detects and corrects single-bit errors — required in servers and workstations.
- DDR4-3200 defaults to JEDEC 2133 MHz unless XMP/EXPO is enabled in BIOS.
Meerk's quiz — open the Module 4 gate
10 questions, no time limit. 85% on your first attempt in a 24-hour window opens the gate. Retakes inside the window are practice — they help you learn, they don't count. Work alone; the point is to know it, not to have seen it.
