OCZ continues its work with 4GB memory kits and has now launched a new top model. Earlier on it launched its Vista Upgrade series, which among others contained a 4GB kit, although only running at DDR2-667. Now OCZ has launched OCZ PC2-6400 Vista Performance Gold Edition 4GB and these follows the DDR2-800 specification to the fullest with latencies at 5-5-5-18. We haven’t received the price of the new 4GB memory kit, but you can count on a big sum of money for those who wants to keep Windows Vista from thirsting for more RAM. This applies to all 2GB modules though, simply because they still cost a lot to make.
