Samsung+Sk Hynix so-dimm ddr4 32GB 2x16GB 3200 mhz dual channel. They work perfectly together, pulled from my personal laptop used for 2 years just to upgrade to 64GB DDR4 So-Dimm. Works perfectly, throughly tested!

Please ship this via USPS. My work schedule does not allow me to access a UPS Store, so USPS is the only option that works for me. Thank you—I genuinely appreciate your help.
