THG has current test results of RAM with CL timings from 3.0 to 2.0 for Pentium and AMD CPU's. See the Memory Timing article. Mostly high end CPU's but did include AMD 3200.
Results show virtually no difference in the AMD 3200 going from CL3.0 to 2.0. Basically CL doesn't add much to performance except in a few areas. A different conclusion than THG has been saying in graphics card performance tests about RAM.
