    Picked up a set of Hynix 16GB DDR4 2133MHz ECC RDIMM sticks at a great price. They were packaged securely and arrived in excellent condition. Two of the eight had an issue, but the seller was quick to respond and resolved it without any hassle. Overall, solid deal, smooth experience, and dependable customer service.

    A-Tech Components is very professional company. I had a slight issue that I caused and they responded via email in less than an hour. They took care of me right away. The memory came in anti static paper And rolled in bubble wrap. Then the mailer was bubble wrap lined. The modules look brand new. I highly recommend this company and look forward to doing business with them in the future.

  • Good value RAM

    I am just recently testing. So far so good. I was concerned initially that this being ECC Registered memory would not be recognized well by Asus X-99-E WS mobo while using an i7 CPU, but no issues so far. All memory recognized fine. Simple memory modules but perfect for my purpose (virtualization box). Thank you!
