Bit Tech reports one of their forum members has overclocked an Intel Gulftown six-core engineering sample from 2.4GHz to 4GHz. You can find more info over here.
bit-tech forum member windwithme, who's based out in Taipei, Taiwan, has got his hands on Gigabyte's latest GA-X58A-UD7 motherboard and tested it with USB 3.0 and SATA 6Gbps hardware. In among the many, fantastic pictures and BIOS screenshots though, we noticed he was using Intel's latest 6-core Gulftown CPU and overclocking the nuts off it!
Armed with an early B1 engineering sample, he has overclocked from the stock 2.4GHz to 4GHz (23x175MHz baseclock) on all 6-cores and 12-threads, with the triple channel memory running at an incredible 2,100MHz CL8 8-8-24 1T.
