The Celeron Ds were popular in their day, not for their performance, but rather for their great overclocking capabilities. 14 years after its launch, a Chinese overclocker was able to break the 8 GHz barrier, using the Celeron D 347 processor.
Intel’s Celeron D processors were built on the Netburst microarchitecture and a 65nm process node. The Celeron D 347, in particular, had a 3.06 clock speed and a 512 KB L2 cache. The most powerful processor of this series was the Celeron D 365 which reached 3.6 GHz. These processors only had one core.
The Chinese overclocker Ivanqu0208 took the Celeron D 347 and were able to reach unreasonable clock speeds with about 8362 MHz. To achieve this, an Asus P5E64 Professional motherboard was used that uses the Intel X38 chipset. The overclocker does not comment there was some kind of modification in the VRM section.
The overclocking result is spectacular for a 2006 chip, although it is not the absolute record using a chip from Intel’s Netburst architecture. The absolute record for overclocking with a ‘Netburst’ processor was achieved by wytiwx and a Celeron D 352 reaching 8543 MHz.
Meanwhile, the highest clock speed of all time for an x86 processor was achieved by overclocker Stilt in 2014 achieving about 8722 MHz with AMD’s FX-8370 CPU.
It would have been curious to see some performance test of this 8 GHz processor, but we were left with the desire. We will keep you informed.
