I recently flashed my motherboard for the first time because my AM3 processor was showing up as "AMD Unknown Model" and as i was looking through Everest i realized my DRAM:FSB ratio was at 12:6. To be honest i really had no idea what it ment at first but after a few minutes on Google, I realized that for the best performance it should be at 1:1.
I do alot of gaming on my computer so i always like to push every last bit of power out of my computer, I was reading a different forum about the 12:6 ratio and someone said that their RAM was basically running at half power, Is this true? And if so, How can i fix that and make my DRAM:FSB ratio to 1:1?
Iv always thought my PC ran a little slow for 4GB of RAM. Could this possibly be the reason?

Haha yeah maybe in the late 90's, when there would be a slight performance boost from that, if any. Today it makes no difference.
New thought.. Would changing my multiplier to 8 (from 15.5) and my FSB up to 400 (from 200) fix the problem? Next question is would it be stable?
I'll answer this question all at once. No it won't solve your problem because it won't be stable.
Unless your motherboard will support changing all your other component frequencies like ram, PCI-e, etc. This is because everything bases itself off of the fsb, not just the CPU.
