What is this multiplier

[Random32]

A long time ago when I got my 2600k I figured, Hey, it's unlocked... Why not OC it? 
so I brought it to a healthy and stable 4.2Ghz with a multiplier of 42 since the bus speed is 100 Mhz. 

I've kinda lost my gaming habits but I still use my PC a lot so I decided bringing it back down to stock. I opened MSI Control Center and there was an option to disable OC Genie II, so I disabled it and it restarted my computer. I open up CPU-Z, and this is what I see: http://i.imgur.com/YtfOWQq.png

 

Why is the multiplier 63?!? Shouldn't it be like 16-38 since the 2600k's turbo is 3.8Ghz??? I'm kinda freaked out right now... Unless I'm missing something. I've been out of the loop for quite a while

Sorry if bad formatting/wrong section.

Well the 'x 16.0' is what really matters here.

Taking a look online...

 

Interesting, so my CPU-Z reports '(8 - 42)' for my 42x 100Mhz multiplier.

 

Stupid guess, is it something like double the amount of threads there are + coreclock multiplier? Nope, the 5960x shows 12-33.

If your pc is in power saving mode, it'll down clock the cpu when it doesn't need the horsepower.

What??? It does that regardless of power saving mode. And I'm asking about why my multiplier is x63.

The question is why is the upper multiplier limit 63, since that's a 6.3 GHz speed.

So I just did a stress test to see if it would REALLY go to 6.3Ghz. I pushed my CPU to its max and strangely, it only went to 3.8Ghz, which is the 2600k's default turbo. It was using x38 multiplier and no further. But it still says in CPU-Z that the multiplier is x16-63.

Could be cpu-z is just wigging out...
