Does what it promises. I swapped out a 1GB module in my Optiplex 755 for two, 4GB in total. The memory tests turned out to be correct and I was able to eliminate excessive hard drive swapping and boot lags with the large graphics applications I use for photo editing. And I still have two more slots to expand the machine to 8GB in the future if needed.
