"Empty Overclocking" is a term we just made up, to describe unreal overclocking headroom that does not translate into any performance improvements, with AMD's A8-3850 APU. This chip can be set to run at base clock multiplier value above 29x on some motherboards, that will increase clock speed being reported to you, but that "increased" clock speed will not translate to any performance improvements at all.

Ok, is it just me or is this a bit erm, dumb? Why don't they just hard lock it if there is no point in increasing it anyway?

Well, AFAIK it is not a BE/FX/what shall I call it. So people won't buy it b/c of the unlocked MP, I guess. So the few fools who will "OC" this CPU via the MP will be easy to spot and ID as idiots (one should not trust OC reports without BClk/MP details anyway).

"to describe tests confirm to be unreal overclocking headroom that does not translate into any performance improvements at all"

What does not translate is that sentence... Maximum English confusion... is maximum

Llano/Lynx isn't even supposed to have an unlocked multiplier as far as I'm aware.

This, most enthusiasts should know what to look for if they want to overclock - in the case of Bulldozer this will be the black edition/ FX models. Much like intels K series being monster overclockers and non k's suckin worse than a Maori hooker.

i read somewhere that this dued was saying that all bulldozer ES suffer from the same thing so any clock for clock comparsons with sandy at 4.0ghz where sandy is like crushing BD by like 25% that thats good news for amd because all current overclocks on new models is empty until the bug is fixed so that 4ghz sandy is actually going against the stock BD

So I could take it up to 500x and it would show up as 50.0Ghz?

That's worth the money just to see.

That's about as useful as using photoshop to make a 50 GHz screenshot.

Kudos for bringing more 'conflictive' news to the frontpage, and not only post P.R. letters of many times boring products like usb sticks!!!

Um pretty sure this was known since review day. I think Xbit labs were the first to report the glitch and they got a confirmation from Asrock as well...Not really news worthy.

I find this all rather interesting.

I personally wouldn't get one, but that doesn't mean it's going to fail.
99% of my clients dont O.C.

If a BIOS level update resolves this glitch, then . . . It's all good.

PentiumII behaved the same way. Even if you OC'd with jumpers above the multi it was still locked at its stock. Apparently its locked.

I thought this was NOT a BE chip and there where no addition multipliers above the 29x? I remember reading somewhere quote, "...with the multiplier, you can go down, not up."
