It was 28 June 2008 (Saturday) , coolice came to my house after we did some serious planning. We are going to test the Biostar TPower I45 under ln2 cooling. Our objective is sub 8s in super pi 1M
Cut the craps, let's start the story
like most of the oc sessions , it begins with insulation. Preparation done by coolice
[attachmentid=516582]
The legendary Astra pot in action
[attachmentid=516588]
[attachmentid=516599]
my tiny pot
[attachmentid=516600]
Not much space between CPU and NB
[attachmentid=516603]
ok done. That's why coolice is so relax and meditating there.
[attachmentid=516607]
3pin socket for vcore mod. Done by coolice
[attachmentid=516611]
Molex for vcore and Vmch measurements.
[attachmentid=516627]
Test bed
CPU: C2D E8400
Motherboard: Biostar TPower I45
Ram: Crucial balistix 8500
PSU: Gigabyte Odin Pro 800W
HDD: Raptor WD740GD
[attachmentid=516630]
Let's start! Can't wait to pour the ln2
[attachmentid=516631]
smoking...
[attachmentid=516633]
we try to find out the cold bug of the processor at the beginning, it was around -115C
[attachmentid=516635]
Let's do some exercises first , wprime 1024M at 660fsbx6
too bad, coolice did super pi 4M test as well on 660fsbx6 but the screenshot has gone due to the OS crashed.
[attachmentid=516639]
Vcore 1.72v, everything seems good
[attachmentid=516642]
later on, try to push the clockspeed. 5.899GHz achieved!

Not hard push though, as you can see we are still using dual channel ram.
For Super Pi 1M, best hit 8.156s ,
[attachmentid=516646]
Actually we have better achievement. It was 8.094s but we failed to take down screenshot on the spot.
[attachmentid=516648]
sub 8s , so close yet so far away.
Never mind, it was great try after all
Lastly, thanks to Biostar for the motherboard, also thanks to penapis for the dewar and ln2
