GPU clock synchronization

Hey guys. For all you GPU pros out there I have a question. Should the core, shader and memory clock of all gpus be synchronized? In other words, do they have to be set in a specific way for optimal performance from your graphic card. I have a Overclocked MSI 8800GTS that came with DOT (Dynamic Overclocking Technology) that does this automatically but I recently changed to Nvidia drivers so no more DOT express and I use Afterburner to manually overclock now.
 
You do not have to have the clocks synced. Sometimes, however, the overclock is more stable if they are. Other times, you may be able to eek out a tad bit more performance by say just upping the shader clock. This varies by hardware. Some chips fare better than others and each part will have its own limits.
 
From what I heard, Bandwidth is affected by the setting of the clocks and Bandwidth is especially important when it comes to Anti-Aliasing performance. Can anybody confirm this?
 
Sure bandwidth can be affected. For instance, if you raise your GPU's memory clock, it will have a higher throughput than before. If you raise the core/shader clocks they can process more per second.
