Default CPU Speed

So I just built a new system with the i7 2600k on the ASUS P8Z68 Deluxe Motherboard. I want to do a little overclocking and I though first I would try out ASUS's free "Auto Tuning" utility to see how well it worked.

Anyway I ran it once and I have no idea how much more I am getting out of my processor because I don't know how to calculate CPU speed. All I know is that cores 0-3 are running at Core Speed 1648MHz, 103.0x16. Obviously you don't multiply the core speed by 4, otherwise you get something like 6.6GHz and I would have the fastest 2600k in existence. The BIOS show just over 3.5GHz, which makes much more sense. Is that correct? How do you calculate CPU speed on a multi-core processor?

ASUS P8Z68 Deluxe
Intel Core i7 2600k
16GB DDR3 G-Skill Ripjaws
1TB 7200 Segagte Drive
eVGA GeForce 570
Samsung Blu-Ray Drive
Antec 850 Watt PSU
Windows 7 Professional

Default Re: CPU Speed

Theyre both correct. All cpus have a power saving feature. It downclocks to save power, fron 3.5Ghz to 1.65Ghz.

When you need power, the multi jumps up to whatever its set to
Foldie = i7 950@ 4.0Ghz Gigabyte x58a-ud3r EVGA 970 SC Corsair H100 Corsair hx520 3x2gb OCZ Gold Corsair 650D
Woohoo = L5639 @3.1Ghz EVGA SR-2 gtx 260-216 Hyper 212+ Corsair 1050hx 6x2gb Corsair XMS3 Blackhawk Ulra
