First LN2 overclock session in history

Recommended Posts

More vintage extreme OC related, and now this one is from Japan.

A guy named Kazuhisa Suzuki decided to use dry ice to cool down an vintage Athlon 1.2 GHz mounted in a EPoX EP-8K7A, a motherboard for Athlon / Duron with AMD-761 (North Bridge) and VIA VT 82 C 686 B (South Bridge) on its chipset.

Despite this session have been made with dry ice instead of ln2, i find it very interesting because it's dated from the year 2001 and was made in the country of the rising sun :)

I found this (another) japanese extreme overclock website, named "Futto-Kun" and is dated between 1998 and 2004.

So almost 20 years ago this "awesome crazy" japanese overclocker started to extremely overclock it's DDR memory kit to the limit, pushing it to 2-2-2-2-F settings, and apparently volt modded the cpu core voltage to boot at 1.85v and raise it in bios to 2.0v.

He also anchieved great super pi results with Amd Athlon Mp (socket A).

 

Interesting to say that we have an extreme overclock member named Futto-Kun: https://hwbot.org/user/futto_kun/

In this article, dated from the year 2000, a guy modified memory and cpu (pentium 4) voltages.

He made a step by step of his extreme overclock session.

He beggined with peltier cooling, and them changed to liquefied carbon dioxide (dry ice).

Funny to say that he started his step 2 saying that it was a "Classic work of overclockers..." for the year 2000 extreme overclock with peltier was already considered a classic :)

Mike Guava used fluorinert in competition at MSI MOA, not sure how he flew to China with several gallons in his luggage.

 

First helium?

It's been some time since my last post.

I found this personal website from a japanese guy identified only as "amt".

Taking a look at his posts we can see that he had been overclocking with LN2 since late 90's to at least end of 2000.

He wrote that he decided to create the website because he was receiving too much emails from "overseas" asking informations about his liquid nitrogen overclocking experiences.

He did several detailed topics about remodeling FSB/VCORE/Vio, hardware components, such as 32MB DIMM LTC-10P (Hyundai memory modules), Matrox Millennium pci video board, and even tips about getting an engineering sample for better overclock results!

There is also a topic about his studies on hard mod/volt mod with a book named "The super technique of PC remodeling", by K.Suzuike (don't know who is the author).

Here is his superpi personal record from december 1999 using a pentium 3:

For MANY more information, visit his website, that is still online:

This one was found on web archive, and is dated back from december 16 year 2000.

These guys used a custom cpu pot for slot A and to cool an athlon cpu.

Also, they adapted what i think was one of the first benchtables for extreme overclocking :)

Ok, now this one is gold OC Archeology :)

After some research, i found this japanese overclock website still online:

 

FF page PC index

FF page Celeronを液体窒素ã§å†·ã‚„ã™

 

It has all the overclock experiments made by a unknown overclocker, since 08/06/1996.

This one in particular was made with LN2 on 09/23/1998, using 10 liters of this precious liquid to cool down a Celeron 333.

 

attachment.php?attachmentid=5939&d=1506744613

 

The overclocker did a complete description about the overclocking session, including many photos and results of the experiment, which was very rare for the year 1998 and mostly without any reference to be followed.

We can even say that this is certainly one of the forefront extreme overclock enthusiast with LN2 documented.

To get an idea, the overclocker built a cpu pot with welded copper sheets!

The external pll clocking , is also a Japanese trademark !!!

(you can see it on the 1st photo).

 

Thanks once again , for all these memories , Casanova

Thanks mate, i really appreciate that :celebration:

This thread turned out to be a great extreme overclock compendium, something that I think is very important for the overclock history.

I'm almost sure that the first extreme LN2 overclock sessions were made in the early 90's.

The oldest record I found was a video dating back to 1984 but it is a pioneering experiment done in a scientific environment, and i think it´s very unlikely that during the 80's someone performed this procedure at home as an enthusiast, but in the early 90's it is quite likely, and i'm almost sure it happened in Japan.

Well, it's been a while since last time i updated this thread with good old articles and sources about prehistoric ln2 overclock.

Also, with the migration to this new forum, this thread lost almost all the pictures i attached (the links are still ok)...

I wish i had more time to spare doing this researchs, so if anyone else is interested in continuing, here are the tips to find things on the web:

1 - web.archive.org - try all the search filters this website provides;

2 - google in japanese, using the date tool, to try find something from the 90s;

Any questions you can contact me here or on my facebook page (Victor Casanova Camargo in there).

 

Good luck! :)
