View Full Version : Prepairing DOTHAN for LN2 action...Warning 56K/photos inside...

Hi there.... :D

I just want to ask the experts of the LN2 action if I insulate well my mobo so as to run a DOTHAN on it....... :)

Firstly I sprayed and "tipped" ALL OVER the motherboard with a Plastic spray which can hold from -70*C to 120*C.......

After that, I started to "fix" the CPU bracket of the motherboard so as to fit with my phase change/LN2 container......

Now I was ready to screw it onto mobo......

A bit insulation inside it.....

Now.......Backside of the mobo........I firstly putted the Prommie's back plate with the resistor in it so as to keep the CPU's surface warm and then I double insulate the mobo.......

Afterwords it was time for placing the adapter in it......

Insulate a bit.....

......and a second layer......

QUESTION: Do you think that this is enough for the LN2 action?......or should I do something else too.......

Thanks...... :)

Looks good Hipro, time to maximize that Dothan ;)

Maybe Kinpin will stop in with some tips.

bro nothing stops the condesation from LN2...
Try to put as more insulation as you can...

Ps. Did u repair the adapter?

Unfortunately no Chris.....Despite the burned Mos-Fet, it must be and an IC also burned that can't be found.......at least here in Hellas...... :(

I think it will be enough.. how thick is the insulation on youre tube, so you have an good sealing between the insulation next to the socket. and as unseen said, the more the better.
hipro5
10-28-2005, 11:31 AM
I'll try to cover the tube with as much insulation as possible........Do you think that I've got to insulate around the CPU's socket as well - just in case - ........

Well more insulation near the socket will do you good, make it as thick as you can. this will provide some good insulation.

10-28-2005, 03:41 PM
Definately w/ LN2 you need alot of insulation. On my tube I use 3/4" foam. Sorry don't know metric. I spray the back of my mobo and nailpolish the front. Make sure to seal around the caps real well. If you get a lock up and need to wait for temps. to drop anything nearby will have condensation on it. I would worry about the metal brackets they will surely be covered in frost. ;)

Looks good hipro!
Nice bracket. Can't wait to see what a true intel master like yourself can do with that chip.
Hopefully your chip will love the volts, because those are the ones that usually scale well.

Thank you guys for the tips......... :) :toast:

I'll test on P4C800E-Deluxe which does 277MHz 1:1 with the BH-6 benchable 3D..........and with an expected ASUS P4GD1 mobo.....VGA's will be X800XT-PE as for the AGP which does 780MHz core and 702MHz rams on a prommie with R507(on the cascade it should do better) and - for now - 7800GTX and later on X1800XT as for the PCI-E.......I'll see what I can do......
After that, LN2 will freeze the Dothan and a cascade the VGA...... :)
I'm almost prepared........I have backup mobos if anything wrong happen(hope not)......2 x ASUS P4C800E-Deluxe, 2 x ASUS P4GD1 and 3 x CT-479 adapters...... :D

@ harleybro yes I think I should put some insulation on the front of the mobo around the socket as well........Thanks..... :)

@ k|ngp|n yes I hope my chip could do well too.......We will see....... :)

780/702 on a SS :eek: What vdd/vddq? That thing will FLY under a casecade. I hope the dothan works out well for you. I think 45k ATI might fall soon :D

I hope so too......... :D

VCore = 1.82Volts
Vdd = 2.4Volts
Vddq = 2.43Volts

Cant wait hipro. Hopefully you'll catch Memesema and the other guys that are in the 18's. Is 3d your main thing? I would love to see 4ghz dothan in 3dmark.

Just remember, that aluminum will act as a cold conductor when your ln2'ing. Make sure you insulate heavily between tube and bracket.

Now just tell me whaT makes good 780. Whats the requiremnts. Lol i like to spot =good one myself but how do i do it. What do you look for specific batch number? Or you have Intel guys test one for ya ;)
Good luck with that ln2 Action. Me wants to see results

I know the feeling of having a dud OC on Dothan. Seemed like the upper multi was bugged and lower ones worked.

IF it goes 3.1GHz on air, then it should do about 4GHz with LN2........3.5 - 3.6 with a Moded Prommie and about 3.8+ with a cascade....... ;)

I'll check it in first hand.........It might be the adapter that does this........ ;) I've already moded two of mine....... ;)

it's been awhile since I used LN2, but I know one thing...

plastic and super cold temps, equals brittle plastic.
wouldn't that plastic frame just snap like a twig after a few minutes of use with LN2?

I believe that it will not coz it will be full coated with insulation......BUT we will see......Thanks for the tip...... ;) :toast:

O.o modded CT479? sikkkk, I wanna know these mods.. :p:

what they modded for? better FSB? Better vcore or sumin??

mine only boots @245 so any mods are welcomed :p:

Good luck with the LN2 :D, hope you can fish out a good 780 (3.2 on air) :)

Thanks king...... :toast:

I'll use THREE DDR Maximizers overal..........One for the Ram modules, one for the Vchip(Northbridge) of the motherboard and one for the VGA card (so I will not have any voltage drops on it)....... ;)

EDIT: Hmmmmm.......why not a Maximizer for DOTHAN's VCore as well.........Let me think about it........ :D

A good 780 for you , as i can imagine you and as i know you, must be capable of 3300 on cold air......

The LN2 dewar is refilled and waitting...:D

See you tomorrow on your lab...:D

the chips are not there yet and there's no action without them i guess ;)
so i guess it'll be early/mid next week before the 780 / p4gd1 storm starts
to unleash its manifold rage around here

when i mounted a tube up to my p4c800 and adapter, i had just a tad to much insulation under the adatper and it would "pull" the adpater up and not post..once i removed some it was ok...then i put insulation on top and around teh adapter. Worked out ok for me, i could have done a batter job insulating it, but i was using dry ice.
