💡 How to pick memory
What to look for:
  • Must match your motherboard type (DDR4 or DDR5)
  • 16GB minimum for gaming, 32GB for content creation
  • Higher speed (MT/s) = better performance, especially for AMD
💰 Look for kits in 2 sticks (e.g. 2x8GB, 2x16GB) for dual-channel performance

★★★★★Crucial information
The memory card is crucial no pun intended. Too bad this brand is not going to made for the consumers any more.

★★★★★SCAM do not buy
I brought this directly sold from BestBuy and I received a fake kit of 128gb ram in sealed. BestBuy did not help me in store to return it or get a refund and they made me feel like i was trying to scam them when in reality it was me, their customer. Stay away from BestBuy at all cost!

★★★★★Extenden Ram for mini PC
I bought it for a mini pc and it worked as expected. I have tried before on a laptop, and it didn't work due to compatibility issues.
