P4 660 + Ln2

I had this P4 660 laying around for many weeks, because I had no time for testing. First the hardware I have used:
P4 660
Asus P5WD2 Premium
512mb Kit Crucial Ballistix PC-5300 3264AA664
Zippy Emacs 460w PSU
ATI PCI graphicscard

The CPU did about 4,55ghz with boxed fan and 1,5v. Not too bad I think. On monday I got the LN2.

At the startup I had really bad problems. The mainboard won't start when the temperature of the conatiner is colder than -110°... ok. But sometimes I doesn't boot even with very low clocks, for example 5ghz. No idea whats the problem here, because it's running stable in windows with 6ghz and more.
I really like the solid conatiner. At the beginning I need a lot of LN2 to get to a low temp, maybe one litre or more. But when it reaches -100° then small squirts of LN2 are enough to keep it at low tenperatures--> about -175° at the base when the CPU is running SuperPI with 6ghz and 1,7v. When it crashed at about 6,3ghz I had to wait more than an hour to restart again, because the temp on the conatiner rose so slowly.
I wanted to try to get higher clocks today, but the mainboard semms to be dead :( It does nothing when I hit the power button. Must get a new one :(

I hope I can push this CPU further, but I'm already looking for a P4 670 :D

Nice results :toast: does the board have any mods on it?

I would guess no mods yet judging by the 1.7v vcore. Nice OC I know what you mean about the wait if crashing and needing a reboot. I have been running a 670 w/ LN2 and a solid. Have you been OCing in windows? If so which bios are you using?

keed up the good work! :toast:

nice, and good pics. sorry bout the mobo. is that it for this cpu or are you going to push it more later?

Great stuff :) ln2 is always fun !

hey iceman nice action man ;)
You are the only one in D/A/CH having the chance going for the 7GIG :slobber:
I think when you've done all the voltmods you have a good chance to reach it or at least get near to it.
good luck, will there be an article on extremcooling about all the ln2 stuph (except the topic i've seen yesterday)?

regards SoF

Thx guys :toast:
The board was unmodded, stock out of the box. It is completly dead, but I got a new one today. So more benching at the weekend.
I used the 0408 bios, I read taht it should be the best BIOS. But I didn't like that SetFSB doesn't work with this Bios. I don't like this Asus Tool :(

@sof: I think you won't find a P4 660 that will do 7ghz, I must get a 670...
Article when I have time.

Really nice clocks :clap:

Nice PCI Card ;) :p:

Welcome to the 6Ghz club :toast:

Excellent! Good luck with your new motherboard :toast:

Nice container man :)
Did you make your container yourself??

Nice container, and nice mist, LN2 looks fun :D

A friend made it for me with a CNC lathe :)

nice clocks ... nice container.. nice stuff.. go for the 7 GHz

Time to mod out the board. Very nice results there and good luck getting 6.5+

Nice setup...

tnx
