I recently used this to test several different types of RAM. It works great! See photos for details. Includes the original power adapter and four adapters. This came from a retail computer store that closed in the early 2000's and has been stored carefully (alongside many other vintage computer items) since then. It has been a unique experience reviewing this inventory- like wading through a giant time capsule. If you are interested, please check out my other listings, including many items still in their original packaging. As always, this tester will be carefully packaged and insured. Thank you for stopping by. Have a great day!
