Review: GOOD RAM - WORKS LIKE A CHARM AS ALL CRUCIAL HAS I HAVE USED IN THE PAST
Review: Great memory that works without problems. - I purchased this for my son's computer which only had 8GB of memory and he was having problems running games on it. It was my first time using Crucial memory. I received it and showed him how to install it. The computer fired up without problems and recognized all the memory. It works great and he has stopped having problems running the games that were having trouble with 8GB. We've had it installed for about a month now and it's shown no problems and had no errors. It's a very reasonably priced memory module which you will likely be happy with.
