They better direct their energy to getting those 45nm processors out FAST instead of wasting their time on "Turbo" buttons. My freaking Pentium 150 from 14 years ago had this too. It made it run at Pentium 166 speed. Insane eh

Investing in this is throwing your money away. You are better off making a charitable donation in the amount that you would spend on this. At least some money will go somewhere useful.

I love AMD, and I will hold out to upgrade until they release something good, but feeding this crap to people is very unprofessional of them. My opinion at least.
Oh, so you KNOW K10 won't scale that high....ok my bad. Since YOU know, i guess we can end all the speculation and AMD can go through you for advice. Point is we both don't know but that is exactly what the article is specuating. It may be marketing but it's not going to sell well without the proof. Marketing hype doesn't work all that well with enthusiasts because too many websites these days benchmark.

Either way, you said it was pointless if it doesn't allow the 9850 to OC to 3.6, which is exactly what they were saying it might do.....

So are you guaranteed the 200 and 400 MHz speed boost with the new southbridge?

notice throughout what I've just stated, i don't use absolutes. I'm not guaranteeing(sp?) anything.

Well, I am going to use absolutes and I will tell you that the 9850 will never get to 3.6GHz unless they are doing some stupid pin-mod activating stuff that normally does not work to boost the voltage through the roof, in which case the heat dissipation will also be through the roof. Most of these crappy 9850s can barely pass 3.0GHz.



Edit: I retract that. Maybe they will make their boards and chips ship with liquid nitrogen cooling so you can get them to 3.6GHz.

I could respect your opinion if there was substance behind it. Like if you told us how the SB & Phenoms work specifically and how it doesn't affect it much.....but you haven't, you're just guessing.

Look man, the Southbridge is effectively and I/O controller hub, so all it can do in order to increase O/C potential is do a better job stabilizing I/O devices. That's about it. It truly does not do much for the CPU itself. Now, in terms of what the CPU's O/C potential depends on, there are 4 factors:

(1) Reference clock
(2) Multiplier
(3) Voltage
(4) Thermal threshold

Every CPU has a limit in each. Voltage is the big kicker here because the higher you boost voltage the higher you can O/C the CPU, theoretically. However, this is not a linear relationship but is in fact probably more approximated by an inverse function if anything. The thermal cap is what typically gets you. Therefore, there is not much chance that the SB can do too much to allow additional O/C, unless the O/C limit is due to very poor design of the current SB in respect to being able to stabilize I/O devices.

If there was a button, i would replace "Turbo" with "Kao-ken xTEEEEEEEN!"

Did it ever cross your mind that maybe it was the northbridge causing the unstable overclocks in the phenoms? probably not.

It's really not too farfetched, considering the SB600 was designed for the 580x crossfire boards, which came out before the phenoms were probably even done being designed. It was designed for the K8s... not to mention I think it was ATI who designed it, because they weren't merged with AMD yet.

I'm running a Crossfire Xpress 3200 board and it has a SB600...

The actual SB chip has very little to do with the whole CPU overclocking thing. It's more of a NB thing. Of course, who knows what AMD is putting in the SB700. Some pixie dust perhaps?
All kidding aside, what I really think it is, is special instructions on the SB that get relayed to the NB when the mobo detects the specified CPU (it could be all BEs or just that "upcoming 2.8GHz CPU"), which in turn does some automatic multiplier and voltage adjustments. The fact that AMD is confident that this level of overclocking won't cause instability leads me to think that this will only work on special BEs (yet to be released like that 2.8GHz one in the article).
