AMD overdrive with locked Bios

No, you didn't. Your post can any length, just be sure to break it into paragraphs if it's long enough to call for it.

I actually figured out which motherboard is in there and it looks like the 3870k is the best you can do as you had thought. I cannot however find any information regarding the ability to overclock with an unlocked cpu. It should be possible, but you would need to do it with Overdrive.

You would need to get an aftermarket cooler and honestly by the time you purchase the CPU and a cooler, you could have purchased a better cpu and motherboard. I'd save some money and upgrade when you have enough for the cpu, motherboard and cooler. Also, from what I see on that...

Yes, in some cases. For example, some laptops that have no provision for overclocking, can be overclocked using AMD overdrive. The problem is often whether or not you have sufficient cooling. On laptops, obviously there is no way to install a performance cooler, so overclocking beyond what was intended, generally the turbo mode only, is not a good idea without SERIOUS modification of the case and cooling system.

On a desktop, it could be a decent possibility. It's going to mainly depend on the cpu cooler you have (Don't ever overclock with the stock cooler), the motherboard and the cpu. Is this a laptop or a desktop and if it's a desktop, what are the model numbers of your motherboard, cpu and PSU. Yes, PSU, you don't want to be overclocking with a low quality or even Tier 3 PSU as it's likely to cause issues.

It is a desktop, i haven't bought the CPU yet, The computer im using is a Acer Aspire M3470G with a locked cpu. im not sure what the motherboard is cause its stock. my PSU is a CosairCX 430.
I was going to buy and overclock ethier the AMD A8-3870K or the AMD Athlon II X4 651K so it doesnt bottle neck my 7850. Im on a big budget thats why i cant replace the motherboard.The cooling i have is stock but im willing to buy another fan if i have too
Lol i was begging to think no one would answer this

The budget will probably be the biggest issue here. I'd probably wait until I could afford the recommended minimums as overclocking and halfway don't usually go together well.

The minimum CPU cooler I'd recommend for overclocking would be the Cooler Master Hyper 212 EVO. It's the #1 budget CPU cooler for overclocking and can be had for about 28.00.

The motherboard is going to be important because even with Overdrive, if the mobo won't allow multiplier and voltage adjustments, it isn't happening. Acer is well known for using minimalistic hardware, sometimes even proprietary components, and I'm not sure what board is in there. You would need to remove the side panel on the unit and find the model number which should be printed somewhere on the board. Depending on the BIOS, it may or may not even support an unlocked cpu which would be the defining factor on whether or not it could be overclocked. Without knowing the motherboard to determine cpu support, myself nor anybody else could tell you much as there are probably multiple motherboard models that could be in that Acer desktop regardless that it's a specific PC model.

I have a number from CPU Z for motherboard model would that be same thing(Aspire M3470G)? And i don't know if it makes a difference but i can increse the voltage to my video card with a issue, and the option for incresing voltage in AMD overdrive isnt disabled. But trying to change the clock speeds on my current cpu gives me a inconsistent clock speed (probley cause the cpu is locked) Sorry if i put too much info into one post

I'd save some money and upgrade when you have enough for the cpu, motherboard and cooler. Also, from what I see on that motherboard it has VRMs that barely provide the necessary power for stock speeds and demands and would likely end up failing if overclocked via Overdrive.

Boards that are not overclockable using the BIOS are usually that way for a reason and that reason is that the motherboard components are not designed for it.

Overclocking a graphics card is a different story as the lack of quality motherboard components doesn't generally affect that as much, so while the GPU may overclock using Overdrive without any issues, you'll likely cause a failure if you overclock the CPU on that board.
