I've had the time or the memories were worth an arm, then find at that price it's crazy! Convenient to upgrade old machines that still serve. Samsung memory chips, modern DIMM location and clean, efficient packaging, perfectly consistent with the picture and description. The day after delivery of the order, directly into the box, bravo. Considering the price I feared some waste, but nay! In use on a PowerMac G4 DP500 2001 mounted with 4 x 512 RAM, no installation problems, seem pretty fast and smooth, flawless to date stability. Highly recommended.
