Vista - DDR RAM Explained

because the bios has set the ram timings at a safe operating environment, looser timings set by default usually means that your CPU is running 1:1 with your ram, your CPU is slowing the timings down to get a faster speed. if you want tighter timings on your ram, you could increase your CPU clock frequency to reflect this so effectively your running 1:1 even at higher clock speeds, theres more in common with your cpu and ram than you might think.
I found this out the hard way, my windows experience index was telling me my ram was slow (5.5) and my CPU was fast (5.9), i overclocked my CPU to 2.8Ghz and my ram was released to do its dirty deeds and bumped up the ram to 5.9, it confused me at first but i realised that my CPU was slowing my RAM down, running it in 1:1, like a Dam holding the water back, as soon as i removed the barrier, i was overwhelmed with how much performance was gained.
pics are before and after ive since overclocked my CPU to 3Ghz

Thanks for the explanation!

My DDR2 800 RAM (dual ch)is running under 1200Hz. However, i cant see big improvement over 800Hz. (constant timing) .
Should there be less apps that are FSB bound.

the only way you'll notice a difference above 800mhz with DDR2 is while ''number crunching'' , tighter timings & a lower frequency can often deliver the same or better performance......

obviously DDR3 is different


& i dont undertsnd what you mean by ''apps are FSB bound'' ??

yes. ddr3 makes a huge difference.

Many apps im using tend to have overwhelming computation tasks other than memory bus thirsty. These apps are not FSB bound (aka. performance limited by FSB).
