Bios setting woes

[Smarted]

I have just installed a Duo 6850, and my bios is showing correct 3000mhz, but when I run 3d mark is says its running at 2400 and cupz says the same, it's driving my mad . Any ideas?

I think you will find that it is " Intel speedstep" ,can be disabled via the BIOS, if you wanted to.
Enhanced Intel SpeedStep technology allows the system to dynamically adjust processor voltage and core frequency, which can result in decreased average power consumption and decreased average heat production.

Thanks hse180
But I have disabled speedstep and it makes no difference, I have tried changing the multiplier to 11 from 9 and again on change it detects the multiplier as 9.

the correct setting should be 9 x 333

what motherboard do you have?

you may have to manually increase the FSB to 333

The motherboard is a Asus P5N32-SLI SE, I have updated the bios, that gave me some new bios features but did'nt fix the problem. I have tried setting it to 333x9 with the overclock utilty but the system crashes, should I have cleared the cmos? Or change the voltage?

You may have to put a little more juice through it. But only go in small increases at a time, reboot see if it's stable enough to boot into windows (if not another increse is called for) then run something like prime 95 for a while (hours, rather than minutes) to see if it is stable while under load, again if it fails this, a little more juice.

It can take quite some time to get set up, but it is worth doing right.

Remember too much of an increase can fry your cpu, so take it slowly.

Hope this helps.

Thanks all,
I have found the problem my motherboard only suppports 1066 fsb! This came as a big suprise to me, but my fault for not checking properly. so i either try and clock it up a little or I go mother board shopping. 'O' the joys of computers (aka money pits).
