This RAM was purchased from Star Tech, comes with a lifetime warranty, and is completely original. The reason for selling is that I will buy a new PC after my SSC exams. The new PC will require DDR5 RAM, and since this is DDR4, I won't be able to use it then. I have used the RAM for less than a year. Due to exam pressure, my PC was not used for long periods, so the RAM has been used very little. Its condition is still very good. I still have all the details including the purchase memo and card. Those who are interested in buying can message me. Also, let me know if anyone wants to know the difference between fake and real RAM.
