Hi. I have an older computer and I would like to increase the ram. It has a Quad Core AMD Phenom II X4 955be, msi 770-c45, 2x2gb ocz3p1333lvam4gk, and NVIDIA GTS 250 video card. I just put in a WD blue 500GB SATA SSD. I would like to add two 8GB sticks of ram. I am running Linux Mint 20.2 and don't overclock anymore or do any gaming. What brand and which sticks of ram would you recommend. Thank you as always.
