Gulftown sample pushed to 6.4GHz

— 9:37 AM on September 22, 2009

Who says more cores have to mean lower clock speeds? Singaporean overclocker Shamino claims to have gotten his hands on a sample Gulftown processor, and he's gotten some rather impressive speeds out of it.

Judging by the initial CPU-Z screenshot, the Gulftown sample is meant to have its six 32-nm cores ticking away at a base 2.4GHz clock speed. The CPU also has 12 threads, 12MB of L3 cache, and an LGA1366 package. Shamino ran it in a high-end Evga X58 SLI Classified motherboard.

Subsequent CPU-Z shots show increasing clock speeds until page three, where the processor reached 6.39GHz at a frightening 1.92V. That feat involved a 194MHz bus speed and a 33 multiplier—the sample was unlocked, evidently. Shamino says he couldn't get the CPU stable at that speed, however, even with a voltage push to 2.02V.

Instead, the Gulftown sample seemed to be happier under the 6GHz mark. It apparently completed a 3DMark Vantage CPU test at a still-impressive 5.89GHz with 1.88V. Unsurprisingly, though, those feats involved unconventional cooling. The overclocker says his whole motherboard "got wet" at 6.2GHz, presumably because of condensation.
