EDIT: Look down a few post for a couple pics, plus recorded livestream.!!! vvvvv

LN2 = Liquid Nitrogen

Later today (1/21) me and some guys i know are getting together to get our CPUs and GPUs nice and frosty under some liquid nitrogen.

I'll post pics when i have them ;) Stay tuned

Further info:
-I will be benching almost exclusively AMD parts. Notably, my 8150, (and possibly my 555BE).
-Liquid Nitrogen boils at -196c. Assuming my chips don't coldbug before then, I should be benching at around -160~ -180c
-Not planning on doing any 3D benchmarks, mostly just CPUz, SuperPi, and Wprime
-yes, this is a sport
-we will be streaming it over the internet live (ill post link, if/when i have it)

dude, for once a local guy who benches & isnt a pro gamer. heck ya!
 
It went ok today. MY 8150 is a TOTAL PIECE OF CRAP. Like not even a single redeeming quality. It wouldn't go past like 6.6 for anything. I was ready to drop like 2v through the thing, and hope it died.... (was at 1.9v already)

My 555BE however, was much more cooperative, got a pretty nice validation, worth a fair bit of boints:

(6.785GHz)

Sorry I didn't get any pics personally. Some of the other guys took pics, so maybe i can get some of them up there.

We did stream it live, and you can see the recording here (I am in the brown jacket):

Well, I guess I can throw up these pics of the crosshair board after the fact.

DID YOU LIKE MURDER YOUR MOBO? like sheesh man. it looks like clay and a crap ton of paper towels. LOOKS HORRIBLE. Because ide love to have w/e motherboard that is seeing how mine is horrible. :/ You ruined a perfectly good mobo. Or from what it looks like you did. RAGEEEE
 
That would be to protect the motherboard from the LN2.

Cool stuff reflex. Glad you still had a good time with it. What are some numbers you have seen from others with bulldozer?

if i didn't insulate it like that, it probably would have actually died.

All that is, is gummy art eraser stuff (gray), and then Liquid electrical tape (black, you can't see it in the pics)underneath. All of it will come off. Then the blue stuff is shop towels, which will come out (already took them out actually), and the green stuff is just masking tape.

Once I take off all that stuff, you would probably never know that it was ever there.

That would be to protect the motherboard from the LN2.

one of the guys there with me had an 8120 that did 6.8 (i think) on dice, which is kinda why i am pissed that mine wouldn't do better. This guy on OCN did 7+ on his, and he was using a gigabutt board, so if he had a CHV he probably could have done like 7.5-8. 7GHz should be completely reasonable on LN2 though.....

and, not really to protect from LN2. You can pour like shammy, and get LN everywhurrr. water is the real problem

Nice clock on the 555BE. Too bad about your 8150 being a pain :P

i am about ready to drop kick it
 
common guys, this has got to be interesting for some of the 125 of you.

I'll answer any questions you have. (even if they seem dumb, remember we were all n00bz at one point).

As a result of spending so much time with my hardware, i know a lot about motherboards, motherboard design, somewhat about electricity, and the power plane of various computer parts, overclocking, how to make cold drinks with LN2, a bit about the innerworkings of major motherboard/GPU manufacturers, Liquid nitrogen, my favorite ice cream, etc. ask away.
 
It was already explained what that 'fur' is on the first page, dude.
 
where/what type (copper, aluminum, etc) of pot for a am2+ board? or is there a universal pot i can get? ... i have a 940be in the spare computer, so when my taxes are done im thinking of having a little fun. Also, where can i get LN2? I know where i can get DICE, would that be at the same place?

1. My pot is a commercially available one. F1 Gemini. If you follow overclocking, you have probably heard of K|ngp|n. He is the one that sells the Gemini. He also has a couple other pots depending on what you want to bench. The F1 Gemini and F1 Dragon both have universal mounts that work with 1156/1155/1366/AMD. He also sells another pot, the Venom, which is a bit cheaper, and is much bigger, sicne it it designed for AMD (AMD does not cold bug as much as intel, so you can pretty much get it as cold as you want: ergo, bigger pot= more cold)

His stuff is a bit pricey, but they are some of the best pots you can buy.

Koolance also makes a pot. It isn't great for LN2, since the plastic can crack if you are not careful, but for DICE, it is a great beginning pot.

People like Duniek can also make pots on request. Duniek pots typically have a reputation as being a bit cheaper than the competition, but you get what you pay for.

the best way to find commercially availible stuff like noted above is 2nd hand on for-sale forums.

Another way to acquire a pot is to make it yourself. Many people go this route as it ccan be (much) cheaper than buying one. I won't go into too much detail, but basically, you weld some copper pipe together and end up with what looks like a pot.

2. Typically pots are made of copper base, with aluminum top. Cheaper pots (many of Duniek's pots) are all aluminum as it is cheaper.

3. I get Dry Ice from Safeway (grocery store). Many drug stores/grocery stores/hunting/ fishing stores sell it. It is often used to keep food cold, so those kinds of places have it.

4. LN2 is a bit trickier. Since It doesn't have a practical application to non-professionals, it is harder to find. Most people get it from one of three places:

a)Welding supply stores. Apparently LN is used with welding somehow. Beats me if i know, but these kinds of stores often have it.

b) A specialty store like AirGas or Praxair. These stores pretty much just sell gases and liquids like LN2, helium, etc.

c) laboratories. Many professions like Entomology, use Liquid nitrogen, so often labs where such people work have it.

5. Another thing to consider is transport. For dry ice, this is not a problem, you just need a cooler. For LN2, you need a Dewar, or other cryogenic vessel. Dewar's are massively expensive for some reason, so some people rent them. Your best bet is to find used/dented ones on eBay/CL

Hope that helps a bit, any other questions, feel free to ask. 940BE is a GREAT chip for sub-zero. It scales wonderfully. That thing+some nice DDR2 790FX board = massive ref clock
 
Wow... That's more info then i needed, but very much appreciated... They 940 will be on a DFI lanparty board.... Which when that all came out set a new record at the time in Nevada...
