AMD Phenom II X6 overclocked beyond 6GHz

AMD’s Phenom II X6 might still be officially under wraps, but that hasn’t stopped the tech heads in Taiwan from landing their mitts on them, just so that they can overclock them into oblivion.

In particular, one Taiwanese overclocker who calls himself Luca has already managed to clock an AMD hexacore chip beyond 6GHz.

After managing to secure a top-end Phenom II X6 1090T Black Edition, overclocker Luca decided to see just how far he could push the new chip. According to already-leaked information, we know that the 1090T is clocked at 3.3GHz as standard, although AMD’s Turbo Core technology can push this up to 3.6GHz on the fly.

This is already a high standard clock speed for a package containing six cores, but Luca was determined to see how far he could push it with a pot of liquid nitrogen sitting on top. The test setup was completed by an Asrock 890GX Extreme 3 motherboard, along with 1GB of Kingston HyperX memory running at 2GHz.

The first attempt that he submitted to HWBot showed that he’d got the CPU running at 4,321MHz, and the CPU-Z screenshot shows that the CPU voltage was only running at a conservative setting of 1.472V to achieve this.

However, after a couple of weeks of tinkering, Luca submitted his golden clock speed of 6,292MHz to HWBot. The huge overclock was achieved by taking advantage of the Black Edition chip’s unlocked multiplier, which Luca cranked up to 26x, setting the bus speed to 242MHz.

This wasn’t an easy job, though. The CPU-Z validation shows just how far Luca had to ramp up the voltage in order to get into this territory, with a ridiculously high core voltage of 1.928V. We don’t know whether the CPU survived this ordeal, but it must have got extremely toasty with almost 2V running through it and a clock speed well above 6GHz.

To put this into context, while this is an enormous overclock for a six-core CPU, it’s still a fair bit behind the top clock speeds achieved with Intel’s Core i7 980X six-core CPU. The current HWBot record for this chip currently sits at 6,815MHz. On the other hand, of course, Intel’s chip costs the best part of a grand, while AMD’s 1090T is likely to cost less than half this amount.

With unlocked multipliers, a reasonable price and plenty of overclocking headroom, the 1090T could soon make itself popular with the extreme overclocking community. We’ll be interested to see how far it can be pushed when it becomes more widely available.
