Crashing without giving us an error is useless

It is important to know the why before the what. Unless there is a compelling reason to overclock, don't. It seems like the only overclock that would benefit you would be a 500Mhz bump on the CPU, but only if you are seeing a bottleneck that is slowing your system down. I'm all for having fun, but voiding the warranty on an expensive gpu may not be in your best interest...

Overclocking a 6990 takes some serious power. What psu do you have in your Dell?

Increase the core clock by only 10mhz each time and stress test it every time you increase.

Ummhm okay , so this is regarding the overclocking of an i7-920
I followed everystep here http://en.community.dell.com/owners-.../19310782.aspx

Done everything whenever i go into the BIOS it says its 3.2 GHZ
Normal is 2.66GHZ
But whenever i click on my Computer and hit properties i get 2.66 GHZ and not the overclocked speed i see in the BIOS

I also confirmed it by checking it in the program called CPU-Z

I just need to know what im doing wrong

Please and thanks.

its normal.happened because of d speedstep technology by intel.just trust the value in cpu-z .btw use stress-test like occt to test the stability of your gpu each time you overclock it.
