I havn't tried this yet but was wondering if anyone else has.
I am running Corsair XMS PC3500 x 512 MB sticks x 2 sticks ( total of 1 GB). The best I was able to do as far as timings is 2-5-3-2 in Double DDR mode. The fastest that the memory is stable at is 210 mhz. ( Prime95 torture test)
I was wondering if changeing the memory divider from 1:1 or 5:4 to 3:2... and increasing the FSB but lowering the mhz on the memory from 210 to something more like 180 or 189 mhz would actually result in better performance.
If I run the FSB at 283 mhx ( this is a 2.4C CPU) and the memory at 189 mHz ... the resulting OC would be a 2.4 Ghz CPU running at 3.4 Ghz ( 283 X 12 ) but the memory woulb be running at 189 mhx or DDR 378.
I was planning on running Prime95 benchmark to see if the 256 FFT time decreased to measure my overall system performance.
I am also under the understanding that even higher scores with PCMark and Sissoft Sandra with a higher FSB but worse memory timings may result in higher overall scores on these benchmarks but a better score on Prime95 benchmark is actualy better than a better score on the other 2 benchmarks? Does that make sense , I read it in a beginners guide.
