AMD Phenom II Overclocked To 6.5GHz

An anonymous reader writes "During CES a group of overclockers with access to liquid nitrogen and liquid helium for the extra boost of coldness cooled an AMD Phenom II X4 chip to -232 degrees Celsius. Once they got the chip cooled to this frigid temperature, they pushed the clock speed all the way up to 6.5GHz, which is a world record for a quad-core CPU, and then dished out an astonishing 45,474 3DMark05 score!"

I was there

I was there, too. The coolest it got was approximately -242 degrees C; the warmest was approximately -218 degreesC, at least while I was watching.

The party was the XtremeSystems.org party at its LV headquarters, and it was sponsored primarily by AMD, DFI, Gigabyte, Cooler Master, and Thermaltake. It seems to me that Commodore had a presence there, too.

See ThinkComputers' blog for some more pictures (disclosure: my article).

Metric ?

I don't know what weird kind of units you are using in your part of the world. But the rest of the planet is using Celsius for everyday temperature measures and Kelvin for scientific measures (same step size, different zero).

And on our scale, absolute zero (0K) is -273C.

Thus -242C (aka 31K) is pretty legal and possible temperature. (Although maybe not a very common one outside university labs and mad overclocker's basements)

Now please stop using Réaumur scale and start using what everybody else is using around.

PS: I checked, -242Ré is indeed impossible on Réaumur scale - 0 K is -218Ré

You're off by two orders of magnitude. 6.5ghz is 153 picoseconds per cycle.

I am, my apologies. The end of a long day of physics. That gives a light-distance of 46 mm, or around 5cm. So I got the right final value, just dodgy working.

You got modded funny, but I think you were probably being serious.

I think the reason is that the newer 3DMark suites advanced so much in the realm of GPU-intensiveness, that to overclock a CPU and get a higher score without being GPU-bound, you have to go back to 2005.
