3 GHz PC from Asetek and Pyramid at CeBIT
Asetek, known for its freezer case Vapochill, brings the 2.2 GHz Pentium 4 processor to 3 GHz clock frequency. The tower from the German provider Pyramid will be shown at CeBIT in Hanover. The 3000 to 6000 Euro expensive computer is mainly intended for professional users.
Processors in the Vapochill Tower are as in a refrigerator with a compressor/evaporator combination that can dissipate more than 100 watts of waste heat. The evaporator is mounted on the processor and insulated so that the ambient air cannot condense. The processor is cooled to below freezing point. A pre-series PC ran in the laboratory of the magazine c't on 3 GHz, but not 100% stable. Only after reducing it to 2.908 GHz was the computer able to run stably. But Asatek is already working on the settings to get the computer to run stable at 3 GHz. In order to enable the increase in clock rate from 2.2 GHz to 2.908 GHz, the FSB (front-side bus clock) had to be increased to 132 MHz, which meant that the PC2700 memory modules ran at 173 MHz. The test was done with an Asus P4B266 motherboard with an Intel i845D chipset.
