*** FROM A SMOKE-FREE, PET-FREE AND VAPE-FREE HOME.*** Only reason for selling is the computer these were in has been sold. I've had these modules for a few years, Perfect working condition. They were originally in an i7 7700K, then an Intel i9 10900 until a year ago. That system has since been sold, Having switch to 2 AMD systems the Ryzen 5000 series does not like the lower-speed RAM. SO- these are up for the taking! As I do a lot of high-resolution photo editing, it was cheaper buying DDR4 2666 at the time. $100 firm. Send me a text message or e-mail! Based in central Duncan. I work for Seaside computers and have done for 8 years, I know how to treat my stuff.
