Issues with AMD Turbo Core

[MTSe7en]

Ok, so I bought an HP laptop for school and very casual gaming and here are the specs...

AMD A8-4500M 1.9Ghz with Turbo Core up to 2.8GHz
AMD Radeon HD 7640g + AMD Radeon HD 7670m 1GB (I disabled Dual graphics)
6GB RAM
500GB HDD

My problem is that the turbo core promises a boost up to 2.8GHz, but the highest boost i've seen is 2.3GHz. I even downloaded AMD Overdrive to check things out in the Turbo Core Control area, and this is what it came up with:

And whenever I try to adjust the sliders at the bottom (the only one i can actually adjust is the first one,) I will put it up to 28x and I will hit OK and then click apply, and then I will head back into the TCC and it will be right back at 23 x. I'm stumped..... Any help would be appreciated. It just feels like i'm getting jipped as it doesn't even hit 2.8GHz as advertised.

have you changed your voltage (VCore)?

overclocking a laptop isn't a great idea... but...

in the windows power management settings you'll see your cpu is likely being artificially hamstrung by the power management settings.

I feel like the cpu won't reach 2.8ghz unless a few things happen: There is enough power/thermal headroom, two or three of the cores are at their lowest setting, and there is something you're doing the programming feels it needs a high overclock on a single (or two) cores.

fair point from ingtar33

have you changed your voltage (VCore)?

No, it's at 1.075v atm but I can edit it.

I never recommend overclocking laptops but voltage is very important and could be holding your clock back

Is it really considered 'overclocking' if my CPU promises a boost up to 2.8GHz? And I can turn the sliders up to 23 x, but it asks me to turn off Turbo Core.

AMD's Turbo Core functions similarly to Intel's Turbo Boost, then the only way to get to 2.8GHz is if only one core is being used and if the temperature does not go beyond a certain point. There are like different Turbo Core speeds when two, three and all four CPU cores are being used. It could be that 2.3GHz is the max the APU will go when 3 or 4 threads are being used.

Turbo Core / Turbo Boost does provide the laptop / desktop better performance, but not at the cost of damaging itself due to excessive heat.

This is totally correct. I found this out through special testing. The APU will only clock to 1 or 2 of the cores within it all the way up to 2.8.

Also, you can see this if you click the boost level, and select "0"
