So I start taking the temp DOWN, seems to be taking QUITE a bit longer than usual with all the fluid. It seems the OIL was acting like an INSULATOR and was taking a bit of energy to cool. But slowly temps dropped. The rig was OFF at this point, just watching temps.
So it get's a bit colder and I fire her up. I was at about -60C or so... good single phase change territory. Went in and pulled off a 3450, e-z as pie.
About this time I hook up the fluid temperature probe and see our fluid temp is below zero, about -5C. I keep pulling the temp down, into cascade territory
So I decide, OK let's go for screenies at the "hundreds" up to it's MAX. Here's 3500mHz
Starting to see seriously cold temps... way past the Cascade boys
Blasted by 3600Mhz!!
And this is IHS temperature, NOT the base temp!!
So there I am, with 3600Mhz under my belt. The plan is to find a ceiling and come back and run benchies at the "sweet spot". Board is starting to have some difficulties about -120C.... Very bad cold-booting problems, could be the OCZ PSU, too.... they have a rep for that kind of thing. But I managed to pull it down another 20C or so.... and pull off 3700mHz+
By this time, the fluid temp is about -10C, just perfect for most motherboard components
So after 3708mHz, I pull her down to about -135C and openher up at about 1.92Vcore, get into Clockgen and slowly pull her up and up.... 3730, 3760 and at 3796mHz I went BSOD. So immediately I knew it was all about Vcore. I shut her off and upped Vcore to about 2.0v. I knew from experience that this would net me about 3830 or so and THUS!!!!!
THE WORLD RECORD at any spot north of Memesama's 3828mHz.... I was sitting at about -140C and hit the switch, nothing......
and then nothing....
and then nothing.
She never booted up again. I thawed all out and checked the components.... the board would boot and spin the fans and Vid Card, but no video. The HS/F got warm....
I returned home and tested the Vid Card - OK, the DDR - OK so , it's between the FX-55 (doubtful, as it warmed the hs/f) probably the K8N Neo2.... or the OCZ PSU.........
So that's it.... it's all I've got for you!!!! Didn't quite accomplish what I wanted to, but had a lot of FUN!!!!!!
Lesson #1 from benching LN2 >>>>> Go for your highest best bench FIRST!! Just incase you kill something!!! Only has a chance to run 1 Superpi benchie @ 3400+mHz and 24s....
Even had about 5 liters EXTRA LN2!!! After feezing just about everything at work, I even had to throw some away
THE END

wow.........computers submerged in liquid....technology of the future
wow and i have easy access to LN2, its a shame i cant just got allmost kill my parts like that

A cascade is a cooling unit similar to a Vapochill, but functions like a Vapochill cooling a Vapochill, cooling another vapochill.... and gives real nice low temps, maybe -80C or colder

ooooo tasty! he-he thanks proper good job too :
