Just a boot screen?

I hope it ran without crashing.. that's the real benchmark..

i'm to lazy to read the article..

What I find funny about the whole thing is that I understood the Finnish summary almost as much as the Finnish one.

Well I meant the English one, so evidently I don't know much about the language I speak either.

aha! so you do understand finnish! for you see my post stated "jamie if you understand this i want you to reply with how do you get the accents to show up above the letters which you did!

finnish is a rather compact language

I was having a bit of trouble conjugating a few of the verbs but I'm glad it worked out. Seriously though, how did you get the accents to appear above the "a"???

i have no idea..cut n paste from the babelizer i know of a few by holding down alt with a key but that's mac only. *shrug*

it ran stable at 3630mhz it says.

hold down the 'alt' key and press 1-2-8, then release. increasing by increments of 1 up to 1-6-8 and you get: Ç, ü é â ä à å ç ê ë è ï î ì Ä Å É æ Æ ô ö ò û ù ÿ Ö Ü ¢ £ ¥ P ƒ á í ó ú ñ Ñ ª º ¿

tadaaaa!

Today we cooled the new Intel Northwood 2,2GHz CPU with liquid nitrogen (LN2 -196°C).

The motherboard used in the tests was Asus P4B266 based on the Intel 845 chipset (DDR). There was a voltage modification on the motherboard which allowed the VCore to be raised as high as we needed. The memory module was Crucial PC2100 128MB and memory settings were the fastest possible (CAS 2 2-2-5).

We used a copper bowl on top of the CPU and poured some LN2 into it. It took a while until the CPU temperature started to drop and when it was cold enough, we started the test.

First test was run at 3300MHz (FSB 150MHz) and with no problem at all (VCore 1,9V). The next step was rather high but after raising Vcore to 2,05V Northwood worked stable at 3520MHz (FSB 160MHz). We went on with the tests and finally hit the limit.

We were able to boot to Windows 2000 when the CPU clock frequency was 3675MHz (FSB 167MHz) but we couldn't run any benchmark programs. The highest STABLE CPU clock frequency we were able to reach was 3630MHz (FSB 165MHz). At 3650MHz we were able to run heavy benchmark programs such as SuperPi and Pifast successfully although the VCore was quite high (2,12V). It seems that Pentium 4 can handle it without any conflicts.

Check out the pictures above

I think the 3675MHz Wcpuid-shot we were able to get can be considered as the overclocking world record at this moment (17/01/2002), but I'm pretty sure the Japanese will try to beat it as soon as possible :)

BTW, Quake 3 Arena was quite fun to play when the CPU was running at 3500MHz! o_O

what does CAS 2 2-2-5 mean? what's a Vcore?

are there any practical applications to all this?

that is the craziest job I have evar seen..whoa...I've seen some cool stuff but this overclocking takes the cake..

what a waste of money/time...

Peace

Vcore is the measurement of the voltage actually going to the chip socket.

Practically there is as much use for this as adding a spoiler on a chevette.

Simply put, CAS Latency is a number that refers to the ratio - rounded to the next higher whole number - between column access time and the clock cycle time. It is derived from dividing the column access time by the clock frequency, and raising the result to the next whole number. This formula is:

CL &gt;= tCAC / tCLK

Where:
CL is CAS Latency.
tCAC is Column Access Time.
tCLK is Length of Clock Cycle.
For example, if the tCAC is 20 nanoseconds and the tCLK is 10 ns. (as with a 100 Mhz. bus), then the CL must be 2. However, if tCAC is 25 ns., then CL must be 3, since 25/10 = 2.5.

or a number that really means very little other than the fact that you can change it to effect your performance in the BIOS.

CAS 2 is CAS Latency 2 .. most normal cheap ram is CL3 and it's about the Cycles / Timing of the RAM, lower is better


And VCore is Voltage Core on the CPU.
It only can pump out so much by default, they mod it so it'll pump out more juice.

CL2 is all the normal overclocker worries about, VCore mods are for the hardcore freaks with A/C in their boxes.

Only real problem was that the guy spilled some liquid nitrogen on his hand and shattered it on the desk. That white stuff on the M-Board is flesh not condensation.
Cooool!!
