Overclockers Online has published a new article on Ultra Products Xtreme Low Latency memory modules.

Ultra Products has proven itself as a quality provider for a
number of products. While they are still relatively new, their
reputation has grown exponentially with the success of their X-Connect
power supplies. These memory modules have certainly put Ultra Products
on the map for high speed, low latency DDR kits. The quality of the
product does comes at a reasonable price. This 2*256MB kit retails for
95 dollars at Tiger Direct. At this price, you won't find very many
other 2*256MB kits at this clock speed. In addition, Ultra Products
guarantees performance of PC4200, which is something not all competitors
will do.
