Core Needs: Smooth streaming and office work, LOL at 60 FPS

Best Pick: DDR4 3600MHz 16GB Dual Channel

YUNZE Silver Knight DDR4 3600MHz (16GB×2) is now down to ¥349—cheaper than an 8GB stick two years ago. Tested with 20 browser tabs, WeChat, and NetEase Cloud Music open, memory usage stays below 70%.

Pros:

  • Dirt-cheap last-call DDR4 deal, works with older motherboards.
  • CS2 and Genshin Impact at medium settings hold steady at 60 FPS.
  • Office PC stays future-proof for 5+ years.

Cons:

  • Not suitable for AI image generation or 4K video editing—bandwidth can’t handle Premiere Pro real-time previews.

🔍 Avoid These Traps:

  1. Stay away from no-name memory chips! Look for ChangXin A-die or Hynix CJR chips.
  2. The difference between 3200MHz and 3600MHz is less than 5%—go 3200 if you’re tight on budget.

Core Needs: Smooth 2K gaming in AAA titles, light content creation

Best Choice: DDR5 6000MHz 32GB Kit

YUNZE DDR5 6000MHz (16GB×2) is now ¥599, with timings tuned down to CL36. Tested in Cyberpunk 2077 at 2K resolution, DDR5 gives 12% more FPS than DDR4, and AE rendering speeds are 1.8x faster.

Pros:

  • DDR5 prices have been slashed—absolute steal!
  • Supports AMD EXPO & Intel XMP3.0 for one-click overclocking—easy 6400MHz even for beginners.

Cons:

  1. Older motherboards need a BIOS update to boot.
  2. Runs hotter than DDR4—invest ¥10-20 in a heatsink.

💡 Pro Tip: Buy bare Hynix A-die sticks and manually overclock to 7200MHz—beats any prebuilt RAM in the ¥800 range.

Core Needs: 8K video editing, Unreal Engine 5 development, 4K 144Hz gaming

Money-No-Object Pick: DDR5 8000MHz 64GB RGB Kit

G.SKILL Trident Z5 DDR5 8000MHz (32GB×2) goes for ¥1999—definitely not a rip-off! Tested with DaVinci Resolve, real-time playback on a 4K timeline is butter smooth, with memory bandwidth maxing out at 128GB/s. Full RGB sync with Razer peripherals for maximum bling.

Pros:

  • Supports motherboard OC tech like ASUS AEMP II & MSI Memory Boost—pushes up to 8400MHz with one click.
  • Lifetime warranty + full refund if liquid cooling leaks—spend freely!

Cons:

  1. Requires a high-end Z890 motherboard.
  2. In gaming, FPS difference between 6000MHz and 8000MHz is under 10%—pure gamers will overpay.

🧐 Fun Fact: Micron’s Crucial DDR5 5600MHz laptop memory, when installed in a gaming laptop, can unleash full mobile RTX 4090 performance.

  1. Timings matter more than frequency! DDR5 6000 CL36 has lower latency than DDR5 6400 CL40.
  2. Dual channel > Higher capacity! Two 16GB sticks outperform a single 32GB stick—bandwidth doubles.
  3. RGB = More heat! Light-up RAM runs 5-8°C hotter, increasing the risk of thermal throttling.
  4. Check motherboard compatibility (QVL list)! Don’t trust “supports all motherboards” claims—ASUS’s official QVL list is the most reliable.

🔥 Final Advice: DDR4 isn’t dead in 2025! If your full build budget is under ¥2000, go DDR4 and invest the savings in a better GPU—better performance per dollar. Don’t fall for spec chasers—buy what you actually need!
