what are you on about? Why lower your memory clock? How about so its not severely overclocked and the PC refuses to boot?

Never saw anything saying system refused to boot, if his ram is handling the current clock shouldn't he raise the fsb to match and get the extra performance from the cpu?

But if he raises his FSB without lowering the default RAM speed he will overclock his RAM too far and the PC will not work with overclocked RAM. Without lowering the stock speed of the RAM you cannot continue to raise your CPU speed.

Example: My RAM's default speed is 200mhz, in order to overclock I reduced that default speed to 166mhz in order that as I increased my FSB it gradually came back to 200 again. It is now running at 217mhz as it runs stably there, I could lower its default to 133mhz and have it run around 180 if needed, or if I could OC my CPU more

In my case, I have to go into the BIOS and then : Advanced>CPU Configuration>DRAM Configuration and set the Timing Mode to Manual.
I don't touch the timings but you can adjust your memory frequency from here.
Any CPU adjustments, for me anyway, are in the same Advanced menu but under "Jumperfree Configuration"
Anyone reading this can tell me just how wrong I am I'd like to know if this helps.

Ahhh, sry. My mb auto adjusts my ram 1:1 with fsb, and I have never had to adj my ram clock. I did not know that changing the fsb would auto adj the ram clock on other boards thanx for the correction.

so your mobo lowers your RAM speed automatically as you increase FSB?

As you increase FSB, on all motherboards, you dont just increase your CPU speed, you increase your RAM speed as well. Most mobo's you have to manually underclock your RAM in order to keep it close to stock as you increase FSB - since RAM doesnt OC too far in general (especially cheaper RAM)

Maybe I am lucky, because my multi is (10x250) and it adj's.. 1:1 fsb-ram clock. Is it because of the magic #10?

no the cpu multi doesnt affect RAM speed, I guess your mobo just autoclocks your RAM down for you
