Video: AMD CPU overclocked to 8.429GHz

AMD set a new world record for CPU speed, overclocking one of their upcoming 8 core FX chips to a speed of 8.429GHz.

The blazing fast speed was achieved by cooling the CPU to -180 degrees centigrade using liquid nitrogen cooling.

The achievement, which tops the prior record of 8.308GHz, was officially recognized by earlier this week by Guinness World Records. They presented an award to the company at an AMD technology showcase in San Francisco, Calif.

Although that's not particularly useful for the typical consumer, AMD also managed a significant speed boost using air and water cooling.

AMD's Simon Solotko wrote:

Even with more conservative methods, the AMD FX processors, with multiplier unlocked throughout the range, appear to scale with cold. We also achieved clock frequencies well above 5GHz using only air or sub-$100 water cooling solutions.

The AMD FX CPU is expected to be available later this year.

Crazy, liquid nitrogen would be the most effective way; but then that's just cooling the CPU, if you really want your rig fast you want the entire system to be caught up.

Just threw this in my rig to run Ubuntu with 2GB RAM.

I could use that...I once over-clocked and Q-cored my Phenom II X2 555 BE to 3.4 ghz with to convert some HD videos..and then it never let me do that again!..and now the stupid CPU fan spins at full speed all the time! so damn noisy..

Seems like yesterday when the 1 Gig barrier was achieved.

Not so sure using LN2 is fair. The CPU should be tested using cooling fan(s)and or a liquid cooling setup that Joe Blow can purchase.

LN2 is a short lived coolant solution. Still, 8+ Gig is truly amazing.

well ive got this going for me atm and today is the first day ive had the cpu

HexaCore AMD Phenom II X6 Black Edition 1090T, 3800 MHz (18 x 211) i could prob reach 4ghz pretty easily with my air and prob 4.3ghz with semi decent water cooling

I still have an i7 920 able to run at 4 gigs in air. It has now been running at a safe 3.44 GHz for almost two years.

i know i can get up to 4.3ghz with air but it aint very stable in the hot aussie climate
3.8ghz is very stable even after hrs of stability tests
3.9ghz is stable 99% of the time so far but after some tweeking i think 3.9 could be stable and 4 might be a possibility and 4.1ghz would be a stable possibility i reckon if i opened my case instead of it being stuck with the hot graphics card and hard drives etc

The ATCS 840 case has an external fan kludge that draws a lot of air from the NVidia 295 GTX. The fan I installed sounds like a 747 taking off.

Ran a newer version of Super PI for a stress test @ 4 GHz. It passed without an error over a 24 hour period. Older versions of Super PI only test to ~2 GHz (I think) which makes it useless for CPU's with real zots.

I miss the good old days when you could double a processor clock using nothing but air cooling. The only thing keeping processors from running at 3x speed using phase change cooling was the FSB.

"I miss the good old days when you could double a processor clock using nothing but air cooling. The only thing keeping processors from running at 3x speed using phase change cooling was the FSB."

Yep, that and an unlocked multiplier. They seem to be making a comeback... That is if you have enough $$ to spend. The i7 920 will only do a 20 or 21 multiplier. So RAM timing and FSB (or whatever it is refereed to nowadays) speed are the only options.

Old man memory failure.. ;)

my new setup has unlocked multipliers and unlocked motherboard chip sets and this morning i have made 3.9Ghz stable :)

I'd rather upgrade the mobo to something faster....

Until lobbying is a hanging offense I choose anarchy!
Ah modern gaming its like modern film only the watering down of fiction and characters is replaced with shallow and watered down mechanics, gimmicks and shiny-er "people".
