How do I calculate my FSB:DRAM ratio - Page 2

post #11 of 14
Thread Starter 
wow that's a lot of information to digest.
My P5N-D suffered a lot from Vdrop, i.e.what reads in cpu-z is lot lower than what i set in BIOS, i looked around and there is no such option like vdrop control lol .. also 1333Mhz is the maximum FSB the mobo supports says on the box, i tried anything beyond that would simply fail at booting up the system. what I want now is a 1600 fsb to achieve 1:1 ratio to my dram's stock frequency , is there anything i can do about this?
otherwise this mobo is not suitable for stable overclocking, seems like i might seeking to sell it and find a better one in terms of some serious overclocking lol anyway , thanks for the helps

what is the correct one?
It's 5:8. The problem with dram is you have real clock and effective clock. Real clock on that dram is 533mhz. The bigger the real clock the huger the effective clock and the more you can say you are fast without going any faster. That's how computer industry squeezes improvements out of nothing.

Unfortunately some mobos can't break the 400 fsb mark Also keep in mind that 1:1 ratio isnt always needed in achieveing a stable overclock. My system is stable even though my ratio is 3:4.
If you want a good oc friendly board and you would like that q6700 hit 3.6GHZ get a Gigabyte EP45-UD3P but then again idk if your CPU will oc that high. A better aftermarket cooler would also help getting higher oc:s

Actually, I said vdroop, not vdrop. As I said, vdroop is what happens when the voltage droops under load. The 750i may have a Vdroop Control, and I do recommend looking for it.

As for vdrop, you are right. It's when the actual voltage is lower than what you set it to.
