My first Dry ice run

[metro.cl]

Well guys after been here for a while and see you cooling methods i wnated to try something better than air or water, so i decided to go DICE, here is my first run i got some problems and oc wasnt great at all.

Here are the pics:

This was the cooler i got, measerured it by the side of the cpu

Benchs, completely un optimized and with divisors some times, this run i tryed to find out my hardware limit.

super pi

Here are the benchs they suck, i brickwalled at 3000mhz i dont know why, i increased volts a lot and gained nothing, maybe is my cpu or mobo (or just me been a newbie) i got plenty of problemas with the hdd (didnt fully corrupt windows but lots of problems and checking) then condensation came and i stopped when i i saw it on the mobo pcb, ambient temp was 24-25ºC.

Well after this try i'm pretty depressed about my results (i had some good air runs on 1m and 8m before lowered by 1sec and 13 secs), i only used 2kg of dry ice then i didnt wanna try again (had 4kg).

Well im acepting tips and trick to improove next time.

This was the rig:
venice 3200+ week 17
lanparty nf4-u bios 62
g.skill le 2x512mb
x800 vanilla
80gb sata hdd (i'll try a ata drive next time)
enermax noisetaker 600w

if anyone wants more pics on high def i got plenty.

Here is all the info on how the container got made, thanks to sebastian for making it i think is a pretty good container

just did mine a few hours ago as well :D

try alchohol in first.. then first few scoop of DI make it powderish :toast:

did the CPU come off together with the container? :S

Sounds like maybe cold bug...your bios temps were good. Sorry it didn't work out for ya.

Try running SP2004 doing small FTTs lowest priority in the background and OC via clockgen next time. Gets around cold bug. ust make sure all benchies are set to run "real time" so they don't lose clock cycles to SP2004. Thats how I got my opteron from 3100 to 3527 ;)

Tube looks good, add some more insulation next time maybe. As long as the frost doesn't melt it's not a very big deal.

yes i forced it and came off with it i got some really nice pics on hi def of the chip freezing.



thanks guys i'll try via clockgen next time, hpefully i'll get better clocks
