Ok so I got a new Amd X2 3800+ and I am over clocking it. Now I wasn't able to go past 225 cpu frequency until I cut my ram from 400 to 333. Now I got it at 2.475 ghz from 2ghz stock.



Does lowering the ram from 400 to 333 change anything besides making the default speed from 200mhz to 166? I mean the ram goes back up to anyway once you start to bump up the cpu frequency. Is this some secret to over clocking I never heard of before until now?

I dont think your ram was designed to do what your planning on doing. For overclockers, you should really have gotten ddr433 or ddr 500 etc. Ur memory Divider is gonna impact performance.

the guys right. ur ram was what was fucking up your overclock. u were trying to run your ddr 400 ram at 450mhz. thats why it would not go anyfuther. by running your ram at that spped you can prob push ur CPU up to about 2.8 with stable voltages....

just keep an eye on those temps...

Yeah I was a little confused about that, I thought the corsair xms ram is supposed to do be great at over clocking. I couldnt get it to go past 225 , which I guess is supposed to be good but I wanted my processor at 2.4ghz at least, I read though somewhere they got the fsb to go 273mhz ddr on a review online using loose timing speeds, but I can't get it to go anwhere past 225 going full speed at 400mhz.

So right now fsb is at 247, ram is running at 207mhz at 333 ddr.

Does anyone know if the ram running at extreme speeds along with the processor helps performance? I mean am I loosing out by running my processor so fast with a bit slower memory?
