WHAT YOU NEED TO KNOW
Memory is a hot market right now. DDR5 and DDR4 are extremely volatile with data centers driving availability to extreme lows. Always validate machine type and model. Remember: all RAM is Hynix, Samsung, or Micron underneath OEM labels — use that to find alternatives. Key checks: Check OEM alternatives — all RAM is Hynix/Samsung/Micron underneath. Double-check what you're quoting in volatile market.
