Bulldozer Does It Again: Overclocked to 8.58GHz
by Kristian Vättö on November 3, 2011 7:45 AM ESTLast week, we reported that Andre Yang had managed to overclock AMD's FX-8150 CPU to 8.46GHz, breaking the former record set by AMD. Andre Yang has now been able to break his own record by roughly 120MHz, which is fairly notable increase given that the previous record he set was only 30MHz greater than the record before that. The new world record is 8584.8MHz to be exact, 123.3MHz greater than the previous. The record is not official yet, though, as it has not appeared in CPU-Z's validation database.
Andre used the same Crosshair V Formula motherboard and the only difference seems to be the higher core voltage, which was 2.076V in the new record (1.992V in the old one). Andre used liquid nitrogen for cooling, so even higher overclocks could be achieved with liquid helium, which liquefies at -269 Celsius while it's -196 Celsius for nitrogen in atmosphere pressure. Bulldozer's upcoming B3 stepping could also improve the overclock-ability, possibly making 9GHz plausible.

Too bad he was banned for life for cheating last year, oh wait, that got reduced to just a year because of the influence he has amongst HWBOT mods. Just goes to show how much resources can influence the overclocking competition community. Need a good chip buy a truck load, want to win a competition, cheat, get caught, pay to have the sentence reduced. Give me a break. He could break 9Ghz and I wouldn't care, it means nothing. He did nothing for the community to redeem himself.QChronoD - Thursday, November 3, 2011 - link
They have the temp for liquid helium correct, it does boil at 4K (-269°C), but they are totally off about LN2. It's boiling point is -196°C (77K) and according to wiki, it solidifies at -210°C (63K). I don't know where they are getting the -253 from.As far as I was aware, all of these super low temp overclocks are done with evaporative cooling. They essentially just pour the LN2 into a large pipe that is sitting over the CPU and let it boil off if it needs to.

Agreed. Glad someone else noticed it!Kristian Vättö - Thursday, November 3, 2011 - link
Sorry about that. I was looking at a Finnish science book (has all these characteristics and formulas etc) and mixed nitrogen and hydrogen (they were next to each other). I was also a bit surprised as I remember LN2 being around -195 too.Thanks for the heads up. Next time I'll be sure to double-check!

All of this overclocking in the wake of an AMD 10% layoff?http://tech.icrontic.com/news/the-axe-falls-at-amd...

AMD is the overclocking king.Intel is the IPC/compute/low power king (i.e. the things that actually matter).

The facts are simple, just quite simple:BD with ~2x elements & ~1.5x die size - performance less than SB!!!
That's I call BIG FAILURE!!!
BD SB NV*
Speed 3.6\4.2~16% 3.4\3.8~12% 0.7\1.4\1.8 GHz
Max TDP 125 95 50 W
Process Technology 32 32 40 nm
Approximate Die Size 315 216 116 mm^2
Approximate Transistor count ~2*10^9 995*10^6 585*10^6 #
*NV GT530 is only for reference.
