IDF: Overclocked to 5.56 GHz Yorkfield Sets 7 World Records
The speech of the CEO and President of Intel Corporation Paul Otellini at the opening of the Intel Hardware and Software Forum (IDF) was rather unconventional. For the first time in the history of IDF, one of the most famous overclockers, the owner of the XtremeSystems website, Charles Wirth, was invited to the stage.
When asked by Otellini about what Charles was doing this morning, Wirth replied that he was overclocking a quad-core Yorkfield processor using an unmodified motherboard based on the Intel X38 chipset, an NVIDIA GeForce 8800 Ultra graphics card, and Corsair Dominator DDR3 memory. All components, except the processor, worked at standard frequencies.
But Yorkfield was cooled to -160 ° C thanks to the use of a three-stage cascade cooling system. This made it possible to achieve stable operation of the processor at a frequency of 5.56 GHz.
Wirth reported that he has already broken four world records, reaching the maximum frequency for a quad-core processor, and the highest scores in the 3DMark 06 CPU, 3DMark 05 CPU and PCMark 2021 tests.
But the audience was much more impressed by the “live” demonstration of this system, during which three more world records were set: in Aquamark 3, 273,000 points were obtained, in Cinebench 10 – more than 20,000, and the SuperPI 1M test was passed in 8.4 from.
According to Charles, he has not yet reached the limit of Yorkfield’s capabilities – due to low leakage currents, the CPU responds to an increase in the supply voltage with good overclocking. When Wirth was leaving the stage, Otellini jokingly asked him to call when the 6 GHz frequency was reached.
Demonstration of the capabilities of a 45nm processor should actually draw attention to Intel X38. After all, not everyone has the ability to cool the processor to cosmic temperatures. But the stability of a “regular unmodified” motherboard based on this chipset will certainly appeal to overclockers below Virt.
