Unlocking X3440 multiplier?

post #1 of 4
Thread Starter 
I was messing around with my CPU OC today trying out the OC Genie function on my motherboard... next thing I know, I am seeing a 20x multiplier. It is supposed to be 19x.
Here is the spec sheet:

I validated it for you all on CPU-Z:

Is this some crazy glitch? Is it actually running a higher multi than it is supposed to?
Is this going to make my CPU unstable?

The i3, i5, and i7 lines have turbo boost and are capable of dropping other cores while increasing one of the cores by one multiplier when not all the cores are loaded to help with single threaded applications.

If you disable turbo boost and manually set the multiplier, it's actually capable of one higher than the stock value.

So its perfectly normal?
Is it possible to get a slightly higher OC using less volts if I have my multi on 20x compared to 19x since I dont have to bump the buss speed so much?

I'm not sure why, but they generally say the odd numbered multipliers are more stable, so it might be easier at 19x. And you would not use less core voltage because the CPU frequency would still be the same, and might actually require more for even numbered multipliers. Otherwise, it's also normal.
