Hi all.
im OC'ing my rig, and trying to understand the process of speeds.
Ive got 2 sticks of Mushkin ram PC3200 (=200Mhz). My default board speed is HTT=200 default (x11=2200Mz). I upped my HTT to 220, and i applied a devider 2:1.83, which gave me a DDR Speed of 201MHz. I upped the voltage significantly (from 1.325 to 1.45), but the system was unstable. So i dropped the DDR speed back, with the 2:1.66 multiplier, and whole thing is stable again, even at lower voltage.
So the question. Why would the DDR be stable at 200 in one FSB configuration, while unstable in another. The logic tells me that they should be independent.
Stablity is
HTT=200, DDR =200 or maybe greater.
HTT=220, DDR is somewhere between 182 and 200,
So by implication the faster i run the FSB, the lower i must make my DDR speed.?
Would it be that ram does not like Frequency deviders?
