7 seconds is dead wrong
That mobo may not support faster speeds, but you go right ahead and put the fastest ram in there you can get. DDR ram is backwards compatible my friends...we all SHOULD know that. If you have a 333FSB, why not buy PC 3200, makes life easier, not to mention that it will help eliminate the ram holdback. In some cases, I have put cheap 3200 in a 2100 slot, and was able to run CAS 2-2-2-5 just because of the low speed requirements.
So you have no problems with ram......most OEM's are only manufacturing 3200 now anyway....
