OC Archeology: 1.2GHz AMD Athlon Overclocked on Dry Ice in Japan, 2001

The history of extreme overclocking is one that extends back further than people often think, certainly back before the ’good old days’ of the hobby. With this fact in mind we bring you another OC Archeology piece that reveals some pretty awesome extreme overclocking happening back in 2001, in Japan. The archeological artifact we’ve dug up today is an article that is published on ASCII.jp and written by Mr. Kazuhisa Suzuki, an overclocker who was also known for his skill at motherboard restoration.

Mr. Kazuhisa Suzuki managed to use dry ice to cool his AMD Athlon 1.2GHz chip below -70 degrees Celcius, pushing it to almost 1.8GHz. The motherboard in question is a EP-8K7A, a board from now largely forgotten Taiwanese vendor known as EPoX which featured an AMD-761 Northbridge and a VIA VT 82 C 686 B Southbridge.

The article covers a massive amount of detail, especially considering its pedigree. Kazuhisa tells us exactly how he hard modded the motherboard, adding a variable resistor so that higher DDR voltages are possible, plus an external dip switch so that voltages can be changed while the system is enclosed in an insulated box. He also goes in to detail about how he added sensors to the CPU, memory and motherboard to monitor voltages. The end result after clearly a lot of hard work was a CPU overclock of 1,799.77MHz, an impressive 48% beyond stock settings.

You can find the original article here on ASCII.jp, as well as a Google Translated version here if your Japanese reading skills are not so great. As with last week’s OC Archeology post, today’s piece was discovered and shared by HWBOT member Casanova. Cheers for sharing bud. Check out the OC Archeology thread in the HWBOT Forums here.

Awesome article from way back in 2001... the very early days of extreme overclocking.

Very nice read :D

Two things though - I think "semi-fixed" resistor should be "variable" resistor, and I think "70 degrees Celcius" should be "-70 degrees Celcius"

Really interesting, thx for digging that out.

Thank you guys, i'm glad you all are enjoying this vintage extreme OC historys. I'm doing this because i know how history is important for present and future generations of overclockers, and also because i love Hwbot and all the effort and commitment that you guys have to spread this art.
