Query: Slightly Faster PC

I installed this 512 MB stick in an old Sony Media PC (PCV-RX850). I had 1 GB of memory installed already and it maxes out at 1.5 GB on the motherboard. This stick improved the PC speed by 36% from a benchmark program I used (Belarc). Not bad and a good price for older memory.
