I bought these (2 years ago) for my build not realizing my mobo wouldn't be able to get the peak speeds this ram is capable of reaching. i found this out after getting my build done at microcenter. so i ended up having to buy new ram on the spot to complete the build, as i didnt want to use these if i wasn't going to get what i paid for. so technically, these are new as they were only put in the mobo for booting up bios and setup. i held onto them thinking i would be able to get use out of them some day. Now, my mobo bricked and i just bought new ram and a new mobo, so i am selling these to help finance those expenses. I put a screenshot of what these exact ones on newegg are selling for as a reference point. I am selling them cheaper to hopefully make a quick sale. If you have any further questions please feel free to reach out, thank you!
