Cpu overclocking question

:confused: QuestionRight. Now, im overlcoking my ram...nothing big...just went from 200 FSB to 235...now...my question is...i see people using the CPu multiplier and divider to bring down the frequency on the ram that has been automatically been brought up with the cpu. Why would i want to do this?

See, right now ..i have it at 235 FSB and the RAM at at a ratio of 1:1.
my timings are 2.5,3,3,7 stable....and the ram is up to 235 mhz DDR470. This is the ram and processor in my sig.

Now..today, i was playing around with A64MemFrequency. Theoretically i could put the FSB at 244 the multiplier at 9, the mem divider at 166 mhz, the DRAM would be back at 200 which is the default..and the CPU frequency would be at 2196.

which would be faster?...and...why would i want to bring my RAM speed back...i am new to this and have seen others doing it. Im just curious and want the best performance for my system. Anyway...any answers would be appreciated.:D
 
If your system is stable, you should keep your divider at 200. When you OC your FSB/HTT, you will also increase the speed of the RAM (it seems you know this). The RAM may not always be stable at this higher frequency. People will cut the divider down to 166 to reduce the speed of the RAM, and thus maintain stability.

It's also commonly reduced when testing for your max OC. Since you want to find the max OC of your CPU, the RAM divider is decreased, so that the RAM isn't the limiting factor.

You're also much faster at your current setting. If I recall correctly, the 3700+ has a default multiplier of 11x, so a clock speed of 2585Mhz at your current settings. You'd loose 389Mhz of CPU speed for a gain of 9Mhz in the FSB, while also reducing the speed of your RAM. Definitely not worth it.
