Hans, <it shows that PC133 with CL3 is not much better then PC100 with CL2 ... Only KX133 combined with CAS Latency 2, SDRAM makes a real difference.>

Once upon a time, even PC100 was CAS3. Then as the memory guys improved upon their technologies, they were able to move to CAS2 PC100. But then the move to PC133 demanded the increase in latency back up to CAS3. Of course, eventually all PC133 will migrate to CAS2 as improvements are made in the DRAM.

The point of all this is not to go nuts over the CAS settings of memory. Tom Pabst already showed that the jump from PC100 to PC133 matters more than the move from CAS3 to CAS2. And Anand showed in his results with "Super Bypass" that the chipset itself can impact performance more than CAS latency. Sure, the lower CAS helps somewhat, but it shouldn't be seen as a holy grail of performance.
