Finnish Guru's Create Worlds First Overclocked 3.6GHz Chip

And you guys think you are tough. What do you think you get when you mix an Intel Northwood 2.2GHz CPU with super-cooled liquid nitrogen? If you are anything like me, a mess but not the folks over at Muropaketti.com. They managed to overclock their 2.2GHz Northwood to a blazing 3.6GHz setting a world record for the fastest Northwood clock speed ever.

Although the article is entirely in Finnish, they were gracious enough to post a short blurb at the end, summarising exactly what they accomplished, for all of us English speaking folks:

Quote:

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.

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!

Ok boys and girls, it seems the gauntlet has been dropped.

This is impressive. Intel showed a 3.5ghz P4 previously. Assuming that Intel would show off the fastest they possibly had, then this would indeed be the fastest. I'm most impressed

Despite the drastic measures used to cool this chip, it does go to show just how high this puppy can clock. I recall that previously some Athlons were overclocked to ~2.2ghz, which was about 50% above stock speed. Given the nature of the Athlon, it won't be reaching that kind of overclock again, most likely, even on a .13 process. The P4, on the other hand.....well, I bet we'll continue to hear of these kinds of overclocks on P4 derivatives for years to come.

Actually, that's 65% above stock speed, it just starts with bigger numbers. Not as impressive as your pro-Intel explanation would have it, eh Paul ?

And trying to guess the future that way has often proved to be wrong, especially in the tech industry. Predict not, lest you bit your tongue about it in the near future.

On a personal note : isn't that impressive, a mere 3gHz above my comp's clock speed *cry*

Believe it or not, I'm not pro-Intel. I'm not pro anything, except having more options at different price points

I'm a consumer before anything else. This too, will be a part of the discussion of an unbeilievably slow-going article I'm working on....
