Ya it has that Visual Bios from intel.. The thing is I have a non k i5 (2500).. When I open advance settings.. it shows multiplier scales for all 4cores.. I am a bit confused! oh & I have 3.3Ghz stock freq.. but the bios says I have 3.70! But that is where I want be in reality.. but why is it showing like that when it's not?

See that max turbo frequency? That's the number that appears in your BIOS. And your processor automatically increases the multiplier of your clock speed to max when it needs it.

I never applied speedstep.. so I assume CPU-Z should show the freq as 3.7 if what the bios says is true! but it doesn't!

It's probably because when you were looking at CPU-Z you didn't have your processor at full load.
Download a program called OCCT, it's really great for stress tests.
When you are running the CPU test, it will bring your CPU to a 100% load and your CPU-Z will show the max frequency.

I had a H61 board.. then I bought this Intel Z75 board.. & BIOS is showing 3.70 right from the beginning after installing the i5 on the board! I ran Windows Experience Index too.. it didn't increase by 0.1/2 like is should have.. ran passmark performance test.. it's the same like before!

I checked using prime95.. CPU-Z shows that it's taking upto 33x instead of 37x!

ANyone knows if Intel XTU is a good option or not?

Here is some information about that, searched a bit around here: http://www.tomshardware.co.uk/forum/269876-29-prime95-t...
I guess it means you can't really hit 3.7 with all cores, only with one core. I'm not sure, would be really good for an expert to check on this.

Well it's from Intel so I guess it's made for their processors. Read some reviews around.
