I guess there's always a positive to something, no matter how bad it is.

I just wanted to explain something here about the use of dry ice and solvents.

Naked dry ice typically is -78.5 c.

Adding solvents from acetone to diethyl ether may or may not make the solution colder , and here's why ;

The drop in temperature is due to 'evaporative cooling' resulting from the solvent .

This is loosely known as "The Faraday Method" .Michael Faraday achieved -110 c using evaporating diethyl ether and dry ice.

I had enough dry ice for a bit more benching today =)
CPU wont boot past 4.5GHz, even with 1.9v (I'm crazy)

Here are some screenshots + validation:

4.5GHz: CPU-Z Validator 2.1

some SuperPi 1M screenshots:

525MHz FSB: 525.jpg - Image - Photobucket - Video and Image Hosting
550MHz FSB: 550.jpg - Image - Photobucket - Video and Image Hosting

Since (obviously) I wasn't connected to the Internet in my carport, I couldn't upload my 3DMark06 score. And for some reason 3DMark06 didn't show me my score, I actually have no idea what my new record is. Here is what I ran it at:
CPU: E6600 @ 4410MHz (490MHz * 9)
RAM: 2GB PC2-6400 @ 500MHz 5-5-5-15
GPU: EVGA 8800GTX @ 700/1010 (this was under my LCS)

And without further adieu:
...
The score actually went DOWN

The GPU clocks were the exact same IIRC. The differences are: 680i => X38, 4GHz => 4.4GHz, timings 4-3-3-8 => 5-5-5-15, XP 32bit => 64bit, official nVidia drivers (169.21) => XG modded drivers (169.61)

The CPU score increased from 3932 to 3572, but the SM2 and 3 scores dropped from 6659 to 6454, and 6920 to 6541. The overall score dropped from 14953 => 14795.

Now that I think about it, I think the shader was unlocked, and clocked a fair amount higher, so thats probably what caused the drop in score.

I'll be submitting the 11.406s SPi time, and hopefully get another point added to the HWC HWBot team.


PS. Does anyone know a good way of cleaning off the residue from the neoprene tape?

EDIT: No HWBOT points :(

Nice job !


Use 99% isopropanol to remove that gunk.

Well, my dry ice runs didn't go as planned. My DFI P965 seems to hate quads after around a 350Mhz FSB, no matter which BIOS revision I use.

I got worse results than last time with my Celeron and Pentium D; this most likely has to do with pumping 1.9V into them for ~3 hours. Anyways, today wasn't all a failure...

I built a NB and a GPU block out of copper using Home Depot piping and a stock Intel cooler.

I'll post pictures when I get the mounting hardware completed. The GPU pot will be able to cool the 6xxx, 7xxx and possible the 8xxx series cards.
