Kingston Fury Renegade 64GB 6400MHz CL32

I am selling these Kingston Fury Renegade RAM modules, consisting of two 16GB x2 kits, totaling 64GB. One kit was purchased new approximately six months ago, and the other kit nine months ago. They come in their original box. I prefer to sell the entire set at once, but I can also sell just one kit. They are still installed in the computer. The reason for selling is that my motherboard cannot fully utilize their speed. I prefer in-person delivery, but I can also ship via registered mail. I do not offer cash-on-delivery shipping.
