Users who run applications which require a lot of memory will love these modules. With modern games eating up more and more memory, hardcore gamers should also think about spending their money for memory instead of buying just another video card generation. What does it help if you can run the eye candy at 100 FPS but have a 0.5 second loading pause every 30 seconds?
The OCZ PC-3200 2 GB XTC deliver very solid performance at stock or overclocked. We saw the best overclocking potential at the CL2.5 setting which is not that much slower than the CL2 defaults. Unfortunately the memory can not run at 2-2-2-x timings, no matter the voltage. But again, the difference between the timings is rather small, and in return you get the benefit of having a lot more available memory for your applications.
However, if you are doing extreme overclocking and benchmarking, where every little bit of processing power is more important than actual memory size, you should continue using 2x512 MB memory kits at the tightest timings possible. If you are now thinking you could just get 4x 512 MB tight-latency modules and run them at their advertised timings, you will be disappointed. Most Athlon64 motherboards are barely able to run with four memory modules, to get them stable you will often have to relax the timings.
