As you can see, in PCMark05 the results are slightly different. Unfortunately I don't have the registered version of PCMark05 so I cannot pin point where the differences in performance are but it still tells us that:
Jammer, you don't need the registered version to see if there is any difference with ram timings and bandwidth. But it does help, however as you can see from your results 4:5 is the best. That does require more Vdimm though than 1:1 with tight timings regardless of DDR2 sticks on market at moment.
- For gaming 1:1 is fastest.
- For general PC use, 1:1 with a bit of an "overspill" (to quote the all wise and mighty RodneyJM) buffer seems to yield the best results.
There is no "overspill" with 1:1, 1mhz goes in to the MCH and another goes out...etc...synchronously. As little time lag as possible on Intel platform.
Now I know that this has probably been discussed many times before but after hearing soo many conflicting optinions, I had to test it for myself.
Comments welcome all...
