AMD FX Sets Guinness Record for Clock Speed
Weeks ahead of its market launch, AMD pulled off a nice PR feat by setting making its trusty squad of overclockers, Sami Mäkinen, Brian Mclachlan, Pete Hardman, and Aaron Schradin set a new clock speed world record (as in Guinness World Record). With just one of its four modules enabled, the eight-core FX-8150 engineering sample was overclocked to a stunning 8429.38 MHz. The chip was able to tolerate a brutal core voltage of 2.016V. Even for a one-in-a-million cherry-picked chip, those are staggering numbers.
8429.38 MHz was achieved using a base clock of 271.92 MHz, with 31.0X multiplier. The memory used was a Corsair Dominator GT single module, which apparently tolerated 3:10 DRAM ratio and timings of 2-16-2-22. That's right, 2-16-2-22. ASUS Crosshair V Formula seated the platform. Cooling was care of a custom liquid-nitrogen evaporator setup. The team used liquid nitrogen as its cooling medium, and switched to liquid helium halfway, which has a lower boiling point. The team cherry-picked chips from the best lots on-site.
A video of the feat follows.
This feat was more of a hit-and-run, in which the system could run at the desired frequency stable enough to make a CPU-Z validation, no proper stability testing was done. AMD claims that frequencies over 5.00 GHz were possible using sub-$100 cooling solutions (now that can be anything between a high-end heatsink and a cheap closed-loop liquid cooler). AMD did a similar overclocking feat ahead of its Phenom II processor launch.

Anyhoo, memory timings were (obviously?) not showing up correct. ;)
I still want to see real world numbers. :D
But there's still a problem with it.
It isn't available in stores! :mad:
Fix that and I will be happy.
If they LNC'd the memory + north bridge / south bridge they could have done more ?
Why the did not try remains a mystery.
Maybe they planned to fail and only reach 121mhz higher ? :nutkick:
I wonder if this FX also suffers from Intel cold / flu when Intel i7 reaches 18C or lower and starts to work worse than above 18C or something like that.
I would be happy, yes. Not because this might be my future processor choice, but because I could stop waiting and buy something and not feel bad about it 3 days later.
Wooden screws can be used in many instances, nVidia does not hold the IP on those. A "fanboi" would be someone blinded by their infatuation, 2 out of 8 is just 25%, and that's a big difference.
Wasn't AMD that complained recently about "dark silicon"? ( <== now that's bashing)
TLDR; Doesn't matter if it does 5Ghz on air, if it gets beat by a stock i7 2600k it's pointless.

Message to these boys: Listen. If you want to be a geeky nerd, fine. But do something to impress us. Don't have a camera focused on yourself like you are doing something that will put us in awe. When it didn't. Fail. Even bigger fail to AMD that thinks this is worthy. Corporate Fail. (And that's even worse!)
