most of the time loosening the ram timmings, but keeping the ram running 1 to 1 is going to help you see a bigger overall performance increase . I find that its better to see what kind of speed the ram is capable with looser timmings than to automatically jump to a memory divder . Some of the decent ram will run a 250 fsb if you back off the timmings to CL3 , and there are some game benches on the net that will show you how much more of an improvement running loose VS running a divder , the extra memory bandwith more than makes up for the timmings .Now im not against memory dividers , i need one to run @ 3ghz and over ,but why not try for the extra bandwith if possible . Ofcourse all of this is moot until he gives us the ram he's usin, it might not be capable of this .
