Casanova Posted October 10, 2016 Posted October 10, 2016 (edited) Does anyone here knows WHO made and WHEN occurred the first extreme Hardware overclock "session" in the overclocking history? Edited September 30, 2017 by Casanova More suitable title 1 Quote
Massman Posted October 11, 2016 Posted October 11, 2016 Probably the Japanese, although the Finnish overclockers (Sampsa, Macci, The Stilt, Kamu) were early too Quote
speed.fastest Posted October 11, 2016 Posted October 11, 2016 This one? Im still 7 or 8 years old then Quote
Oj0 Posted October 11, 2016 Posted October 11, 2016 This one? Im still 7 or 8 years old then Way way way before then. Even South Africa was doing LN2 by then, and we certainly weren't the first Quote
Casanova Posted October 11, 2016 Author Posted October 11, 2016 This one? Im still 7 or 8 years old then Thanks a lot for this link Way way way before then. Even South Africa was doing LN2 by then, and we certainly weren't the first Do you think that Ln2 was on since 90's ? I'm asking because i remember that in 1995 (i was 14yo), i lived in a different city (in Brazil called Barretos, San Paolo state) my father took me and my brother to visit his friend in a new laboratory were they had tons of dewars with aninal samples to do research. That was my first contact with Ln2, i remember the guy trowing Ln2 in our hands and on my brother's head, just for fun. Them some other guy arrived and asked for a dewar that they combined to be borrowed. After a while i remember my father's friend telling my fatther that that guy was using the Ln2 to do "computer research". I confirmed this history with my father last weekend in a nostalgic conversation about the past. I keep wondering how many crazy enthusiastic overclocker guys on this world went extreme and we will never hear about them. If someone else knows a history or photos/videos please share this, it's overclock history, we need to keep as many records as we can Quote
TASOS Posted October 11, 2016 Posted October 11, 2016 Do you think that Ln2 was on since 90's ? There must have been. At least since late 90's If i remember correct , the Japanese were using LN2 since slot-1 era. Fredyama probably knows better. Quote
FUGGER Posted October 11, 2016 Posted October 11, 2016 I was one of the fists, we made pots from brass pipe and soldered a brass plate to it. I still have them, very crude. I made CPU and CPU pots before I made phase change. The answer is buried on XS. Kyosen or Shamino would be my guess. Quote

Great, thanks for the info TASOS, i already contacted him, let's hope he can help I was one of the fists, we made pots from brass pipe and soldered a brass plate to it. I still have them, very crude.

Thanks FUGGER, i'll dig in there then BTW, could you please send some pictures of this pot? Also if you can share more photos/videos of it i'll appreciate it Edited October 11, 2016 by Casanova Quote
Massman Posted October 12, 2016 Posted October 12, 2016 @fredyama would probably have a lot of information on this topic. I don't think a lot of the young overclockers are aware of how extensive the Japanese scene was in 2000 and before. You can also have a look at the blogs using Web Archive. A good place to start digging is Bunny's Workshop. He's got blog material dating back to 1998(!) https://web.archive.org/web/20010124003200/http://www16.big.or.jp/~bunnywk/. Also Sanbe's blog seems to have quite a bit of links: https://web.archive.org/web/20010129052500/http://www.sunshine.ne.jp/~sanbe/ Here's an entry I found on Holicho's blog from December 2000 mentioning LN2: https://web.archive.org/web/20001018124734/http://holicho.lib.net/ Here's an entry from "Sakae" running SuperPI 1M on a P2-450 at 640MHz back in 1999 (which would still be #3 in the Hardware Ranking) https://web.archive.org/web/20000901043203/http://www.hm.aitai.ne.jp/~sakae/manji/superpi8.htm Here's a blog entry from Tatumiya stating -158c as operating temperature for validation: https://web.archive.org/web/20040812055007/http://www.clio.ne.jp/home/tatumiya/index.htm Here's a picture of a Pentium 2 LN2 pot from the year 2000 https://web.archive.org/web/20021202183658/http://www.geocities.co.jp/SiliconValley-SanJose/7039/jyouren.html Quote
Casanova Posted October 13, 2016 Author Posted October 13, 2016 I found more "back to the 90's" material. As many stated here, the japaneses were pioneer in subzero overclock. Despite not being Ln2 related, seems they used subzero cooled carbon dioxide, phase change and peltier back in october 6 1998!! オーãƒãƒ¼ã‚¯ãƒãƒƒã‚¯ã®ãŸã‚ã®æ”¹é€ è¬›åº§ã€Œãƒžã‚¶ãƒ¼ãƒœãƒ¼ãƒ‰æ”¹é€ ã®å‹§ã‚〠Quote
Casanova Posted October 14, 2016 Author Posted October 14, 2016 So there was a TV show from april 2002 were some nut guys used Ln2 to cool a CPU, really amazing because this was a TV show! Does someone here knew this? https://archive.org/details/g4tv.com-video23178 Quote
Massman Posted October 14, 2016 Posted October 14, 2016 The TV show is called "The Screensavers". Quote
Casanova Posted October 14, 2016 Author Posted October 14, 2016 (edited) @Massman I found it, at least i think. In this vÃdeo, dated from !!!1984!!! specifically at 14m55s, a guy is shown putting a japanese super computer to operate with liquid nitrogen. Please take a look. https://archive.org/details/CC126_supercomputers Edited March 17, 2017 by Casanova Quote
bartx Posted October 14, 2016 Posted October 14, 2016 First time when I saw exteme overclocking was this video. It's from Tomshardware article. It's soo cool, even today Quote
FrancoisPiednoel Posted October 17, 2016 Posted October 17, 2016 Probably the Japanese, although the Finnish overclockers (Sampsa, Macci, The Stilt, Kamu) were early too The 1st known overclocking on 80x86 was made by People on 8086 in 1980, upgrading from a 4.77Mhz to above 6Mhz ... It was requiring to unsolder the Quartz on the motherboard, and replace it.(I was part of this wagon) It went from then to the 486DX33Mhz, Where the OC got it up to an incredible 40Mhz ... The 486sx was overclocking badly, as it was the 1st Microprocessor with Integrated memory controller. The 1st overclockable CPU with Frequency multiplier was the 486DX2 66Mhz, that got overclocked to 100Mhz ... wow! (since then, Frequency multiplier is very often the limiter) Internally, at Intel, people have been Overclocking the transistors since then (DX with Frequency multiplier) with LN2, because it allows us to draw very important curves for life expectancy. (Life expectancy of a transistor is a function of how many commutes it does, so, if you want increase it by 50%, you get your answer 50% earlier, then, you have a good math model) The 1st Public demonstration of overclocking with LN2 was done by one of my good Friend, Art Webb, then, working in the demo group of intel, I know he demonstrated a Pentium III, and a Pentium 4 ... I could find internal literature where he was involved into on Deschutes (Pentium II) (internally) Francois 1 1 Quote

I know you must be a very busy person at Intel, but if somehow you have some time left, it would be a great help if you could share content (pictures, videos, scientific paper etc...) about "old" extreme overclock with Ln2 (if you have it). Thanks again Edited October 17, 2016 by Casanova Quote
Crew Trouffman Posted October 18, 2016 Crew Posted October 18, 2016 I remenber that when I did the first ln2 action in France that was because of the Japanese over and the Tom's Hardware ln2 experiment. That was early on for the pot market history and tools but definetly not at the origin. Shammy and fredyama might know more on this... Quote

Shammy and fredyama might know more on this... Thanks for this info I found a video from 1984 where japaneses were making experiments with Supercomputers using Ln2, but tbh that's not a "truly" overclock session. Quote
TASOS Posted October 19, 2016 Posted October 19, 2016 @MassmanHoly mother of balls! I found it, at least i think!

Please take a look and see if you agree with me: https://archive.org/details/CC126_supercomputers Can you share it ? ! It's in this thread already Quote
Casanova Posted March 19, 2017 Author Posted March 19, 2017 (edited) I've just found this very interesting article made by a guy named Ramil Tranquilino, that's basicaly a step-by-step preparation for Ln2 session made in New Zealand. Interesting to mention that these guys used fluorinert, i personally never heard about this being used along with Ln2 in OC sessions. Hardware used: ABIT BE6-2 Motherboard (QJ BIOS) Creative 32MB TNT2 Ultra Infineon 128MB PC133 Celeron 366 This is dated from June year 2000 https://web-beta.archive.org/web/20001019004913/http://www.octools.com/articles/submersion/submersion.html Edited March 19, 2017 by Casanova Quote
Oj0 Posted March 19, 2017 Posted March 19, 2017 I've come across Flourinert before for chilled water cooling, but this is definitely the oldest article Quote
Casanova Posted March 20, 2017 Author Posted March 20, 2017 I found a NASA technical document, dated from 1994, that is tagged with "performance NAS" and "cryogenic cooling". I still did not read it, and it looks very technical article, so if anyone here wants to ready it: https://archive.org/details/nasa_techdoc_20020027082 Quote
Casanova Posted March 24, 2017 Author Posted March 24, 2017 (edited) 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 (ORIGINAL LINK): ASCII.jp：ドライアイス冷å´ã§ãƒžã‚¤ãƒŠã‚¹70℃ã®ä¸–ç•Œã¸ï¼FSBè¨å®šã‚¯ãƒãƒƒã‚¯200MHzã§ã®èµ·å‹•ã‚’マーク!!
