AMD FX-8150 'Bulldozer' Hits 8.4GHz and Breaks Overclocking Guiness World Record

AMD FX 'Bulldozer' Extreme Cooling Demonstration Event

AMD Bulldozer World Record Overclocking Event

AMD recently invited Legit Reviews to their campus in Austin Texas. While we were there we had the opportunity to see an overclocking demonstration with AMD's newest processors, the AMD FX series of processors. Not only did we have the opportunity to see what they could do under air cooling, but we also saw phase change cooling, liquid Nitrogen, and even Liquid Helium! We aren't able to give you specific details on the processor architecture or performance numbers just yet. Today though, we have the chance to see how far the top AMD overclockers are able to push the new AMD FX processors under extreme cooling! While we were there we were able to take some video of the overclocking demonstration, so we thought we would share that with you!

In the video above Simon gives us an overview of the "Science Experiment" we are about to see with the AMD FX processors!

Simon shows of the phase change system that they have an AMD FX processor running at nearly 5.9GHz at just over 1.6 Volts at -40 degrees Celcius!

In the above video Simon Solotko introduces Sami Maekinen and Brian Mchlachlan. Sami and Brian are two of the top AMD overclockers in the world, and today they are going to be shooting for a world record with the new AMD FX processor and Liquid Helium. After the introduction by Simon, Sami walks us through the process he is using to push the new processors.

Above we can listen to Sami talking about the settings they are using to try and break world records with the AMD FX processors.

Sami talks about switching over to liquid Helium. Mentioning that they need to try and keep the extremely cold Helium gasses from going to the motherboard and freezing it. The liquid Helium is capable of causing much more damage from freezing than the liquid Nitrogen is. They first cool down the system using liquid Nitrogen, let that boil out so that the liquid Helium doesn't freeze the liquid Nitrogen!

Here we can see what everything looks like just as they start cooling with the Liquid Helium!

AMD FX-8150 'Bulldozer' - A New World Record?

Once Sami and Brian were set up and the Liquid Helium was pouring out, the fun could begin. Hopefully we would be able to see records being broken with the AMD FX processors!

AMD FX-8150 Liquid Helium Overclocking

The default Bclk on the AMD FX-8150 is 200MHz, the maximum multiplier is x31.5. In order to get past the maximum frequency of 6300MHz if only increasing the multiplier the Bclk was increased to 266MHz to start with additional tweaking to follow as the day progressed.

Once Sami and Brian started dialing in the AMD FX processor, they came up just 4MHz shy of the world record. They weren't done though!

With just a bit more tweaking they were able to push past the record by nearly 30MHz! For some reason though, they wanted more! So they kept pushing the processor and dialing it in!

AMD FX-8150 Liquid Helium Overclocking

By dialing up the Bclk just a bit more they were able to hit 8398MHz! That is nearly 90MHz past the previous world record! They were so close to 8400MHz, they had to go for it!

AMD FX-8150 Liquid Helium Overclocking

They set the Bclk to 271MHz and the voltage at 2.01875! All that was left was to increase the multiplier.

AMD FX-8150 Liquid Helium Overclocking

8429MHz! That is 120MHz past the previous world record! Sami Maekinen and Brian Mchlachlan now hold the current world record for the world fastest clocked processor.

This "Science Experiment" was done on near production level pieces of silicone. Once we get these processors in hand we are definitely looking forward to seeing what they can do in terms of performance. I wouldn't be surprised if the newer production samples will be able to go even further. Should we start taking bets for the date that the 9GHz barrier is broken? Until then, Congratulations Sami, Brian and the rest of Team AMD for breaking the world record by 120MHz with a speed of 8.429GHz!.
