FSB:DRAM 1:1...?

[dragosgorjan]

I want to know what is the influence of the ratio in the system.
If i change to 5:6 it will be higher prority to RAM FSB?

Thanks in advance.

It's not so much a priority issue, but changes the mem clocks with respect to the FSB...

At 1:1 at 200 MHz FSB, the mem is also running at 200 MHz...

Ideally, the ratios would be organized so that as you crank up the FSB when overclocking, the mem is lowered slightly, allowing people to hit 250 MHz FSB while still runing mem at 200 MHz (5:4), although many are hitting 275 MHz FSB while running the mem at a true 230 Mhz, albeit at relaxed timings...

My MB uses simple base mem clocks in the BIOS, 100, 133, 166, 200, so every MHz OC on the FSB is simply added to whatver base clock you begin with...

I do not know if your 5:6 ratio means it runs the mem at higher freqs or not (200 MHz FSB, 233 mem clock?), or if there are really any advantage to it performance wise....
