A note for the reader:

Over the past decade or so I’ve been collecting information on CPU frequency overclocking world record and related benchmark records. During my time at the benchmark aggregator HWBOT, from March 2006 until January 2018, it was easy to keep track of the latest CPU frequency world records. For most record keeping during that time, I refer to the HWBOT database and my personal involvement in the overclocking scene.

For data prior to joining HWBOT, I rely on discussion topics and news articles, CPU-Z’s official Hall of Fame, and older record aggregators such as Ripping.org and Son’s WCPUID MAX Ranking. The latter was a Japanese database which was very active during the years 2000 – 2003.

I believe the CPU frequency overclocking world record timeline data is fairly accurate, though as with all historical record-keeping may be updated.

CPU Overclocking World Record Historical Databases

Katsuya’s November 21, 1998, 716 MHz Intel Celeron 300A

I came across this overclocking achievement while searching through the news archives of the now defunct Overclocking.com website. The overclocking result was reported in February 1999, but the Japanese overclocker had originally reported on the achievement on November 21, 1998, in a personal blog entry.

The blog entry reads (Google Translated):

“Updated information for Pentium II.

Since Mr. Kondo sent me an image during the liquid nitrogen cooling experiment , I will introduce it on the cooling page. I sent an interesting image such as liquid nitrogen boiling in the low temperature range and a thermometer that can measure up to absolute zero degree.

Shooting images, experiment cooperation is [Mr.] Trash and [Mr.] Rocky. Both of them got permission to post articles and post images. Thank you very much.

As you probably know, cooling with liquid nitrogen is at its boiling point when compared with the cooling by liquefied carbon dioxide that I am doing, the decisive difference is its boiling point.

When introducing liquefied carbon dioxide cooling, we performed a low temperature operation test of PC as a preliminary experiment.

I put it in a thermostatic oven together with the motherboard, and I carried out the operation test in the vicinity of -70 ° C, but in short time experiments each device worked without problems.

In the cooling zone using liquid nitrogen, the motherboard itself seems to stop working.

Contrary to the fever of the CPU, in this experiment it may be necessary to make efforts to not cool too much.  In the future, while also careful about insulation around the CPU, the next experiment including the [Pentium II], P55C etc. seems to be planned next.

It seems time is approaching when the operation record of SuperPi [1M] digits breaks the wall of 2 minutes and 30 seconds.”

The cooling system is detailed on a separate page.
