50% FSB.

[Guest BAW083]

While having a wander through my CMOS i noticed the FSB to be set at 50% with the option of either leaving it as it was (default), 0% or 100%.Should i turn it up?

(!!!)But the new T-bred-B chips are good OverClockers!what exactly did you find and where?BTW, you have a killer rig! :)

I also have a board based on the nForce2 chipset. Mine is a Chaintech 7NJS. I don't know your BIOS. But I have set my fully unlocked Athlon XP 2400+ to multiplier 12, clock 183MHz (so CPU internal speed is 12x183~2.2GHz) and memory frequency to 'sync'. This means the memory is also running at 183MHz. In case of a dual-channel memory setup this is the best option for maximum speed and performance. I also have 512MB, but it is setup as 2x256MB dual-channel. This is faster than 1 512MB module. Though this is not a simple yes or no answer, I hope it is of some use.

According to most memory testing and as Corsair plainly states:"one 512mb module is faster then 2 256mb modules of the same speed"What are your sources for your info?Thanks. :)

No. Its 2700 at 333mhz and the initial screen when the system starts up says memroy at 166mhz.That option of 100, 133 and 166 is there but this is another option, on "Advanced Chipset" i think but it's deinitly there.Theres too many options.At the minute everything is on "Optimal" but there is the option to set performance in general as "Aggressive", or to "Customise" it and start settign certain components at different rates.
