So, what can you do to improve the current DDR2 4-4-4-12 memory kits? How about, improve the kits with better ICs and improve the memory timings by lowering them to 3-4-3-8. Of course, this has only been achieved at the factory with 800MHz DDR2 ICs. Patriot has been the first to bring you 4-4-4-12 2x2GB memory kits, now they are the first to give us some 3-4-3-8 kits. This is good news for straight shooter computer users. Check out the new Patriot 2GB PC2-6400XLK Viper Memory Kit.
