Bests & Worsts Reviews from Amazon

only runs at 2666 in new HP Ryzen 4500U laptop that came standard with 8GB of 3200MHz RAM. This was recommended to me by Crucial on their site in a chat session after I told them I wanted to be sure whatever RAM I bought would run at 3200MHz in that laptop. In my HP, the 32GB 3200MHz kit downlclocked to 2666 w/ CAS of 20. Total disappointment and waste of money when the cheaper non-Ballistix Crucial RAM runs faster and at a lower voltage. Crucial needs to get their act together and better train their employees and be more forthcoming in the product description. Sending it back to Amazon today.
