AO522 Netbook VID came overclocked?! (How to change it back?)

post #1 of 5
Thread Starter 
Hello everybody, I hope someone can offer a little insight into this mystery.

I bought 2 Acer Aspire One AO522s (C-50 CPU) but I noticed one was running a little hotter than the other to the touch.

So I ran CoreTemp while playing a 720P movie for 45min.

These are the results from each of the computers:

The correct VID voltage (Netbook A):


The incorrect VID voltage (Netbook B):


These are both brand new out-of-the-box netbooks. Neither had been opened. I have not installed any software on either, aside from diagnostics. They both have the latest BIOs. Everything is the exact same, except for the VID voltage... and I have no clue why!

Can anybody tell me how to lower the voltage on the overclocked PC, so it will idle at 50C-51C like it's twin, instead of 55C-56C? (Netbook B also takes much longer to cool down.)

Thank you for your time.

EDIT: If you think I'd be better off just going in for an exchange, let me know. I still have a few days to return/exchange with no hassle.

Not quite an overclock. The CPU with the higher VID may just need a bit more voltage to run stable, or there's a change in revision for some piece of hardware.

Thank you for the quick reply.

I know it isn't a true 'overclock' but the higher voltage does seem atypical for this model.

I suppose high temp of 74C isn't awful for 45min of 720p full-screen video. I'll test it with 1080p later.

This computer is a gift for my sister. She won't use it for much more than web-surfing, YouTube, Facebook and maybe a little Word. I'm not concerned that it will be unable to handle StarCraft 2, so much as I am curious as to the discrepancy itself.

These are the first laptop-style PCs I've ever bought. Up until this point I've built my own desktops, so I'm a little out of my element here and want to make sure I am not giving her a lemon.

Any other thoughts and input will be much appreciated. Thanks again.

Netbook B may have a worse heatsink mounting than netbook A... you could redo the TIM on that one, but it may involve complex disassembly

Ouch, that's true, too. Could be hardware. I was just thinking voltage.

Hell. It has a flawless screen too. I usually have bad luck with dead pixels. I might just exchange this one then and not chance it.
