You have to hand it to the crew at MadShrimps.be—you really must love to overclock if you take on the challenge of pushing a single-core desktop CPU (you remember those, right?) to performance heights heretofore unknown.

The Belgian hardware site started with a simple AMD Sempron processor, which they point out is generally the best-performing single-core CPU available, running at 2.7GHz. By the time the tweaking was finished, that Sempron had turned into a 5.5GHz monster. After running the test system at nearly 5GHz using phase-change cooling, MadShrimps turned to the chiller of choice for hardcore overclocking: liquid nitrogen (see photo below from the site). But it was only after changing motherboards that the final push was made.

More incredibly, MadShrimps couldn't top the 5.98GHz frequency that another overclocker managed with a similar setup. Sure, buying the CPU container that could handle the liquid nitrogen treatment cost several times as much as the $35-$40 processor does, but it sounds the Sempron is a really cheap way to earn your chops at overclocking.

  • As far as I can tell..

    the liquid nitrogen cooling is also a phase change type cooling. If you pour liquid nitrogen into an open container on top of the CPU, the evaporation of the liquid nitrogen (into a gas) is a phase change, which requires energy, taken from the hot CPU.

    • Not a FULL phase change

      Yes, but you can't turn the nitrogen back into the liquid again to re-cool the chip. Standard phase change coolers allow both directions so that the cooling is continual, not momentary.

  • An intriguing development

    I was looking into doing something like this for a couple of desktops I have lying around-- in order to play games like EVE and Borderlands...

    Now the primary concerns: memory speed (can it keep up) and bus throughput bandwidth... If these can be kept up and COOLED, then maybe.

    (I have a nice AMD Sempron sitting here, on a motherboard, gathering dust, if anyone's interested...)

    How much for the dust?

  • I appreciate the efforts, but this is only a reattempt and old news (nt)

  • Downside

    Near as I can tell, although the CPU would be running quickly, my typing speed would be reduced by having to dedicate one hand to pouring the liquid Nitrogen over the CPU, so I'd net out with a productivity loss . . .

    Seriously, I think Sean is exactly on the money with this one. Many aspiring techies that I know are loath to risk the typical several hundreds of dollars required to get their feet wet with overclocking. But when you are talking about a CPU this inexpensive, a cheap motherboard, and the opportunity to learn about voltage settings, multipliers, bus speeds, the fine details of applying heat sink compound to various coolers(!) and all the dirty fingernail work involved in tweaking without risking breaking the bank, the downside loss risk is minimal for the educational return.

    And being able to crow about achieving even 4+ GHz with a nominal 2.7 GHz CPU, might just get more folks into the hardware game that couldn't or wouldn't otherwise spend the money.

  • and . . .

    WHEN will we need that 5.5GHZ speed?
    Not for at least 10+ years.
    Waste, simply a waste.

    Besides, WHO has the resourses to store Liq-Nitrogen?
    Pfffft, I store mine in my bong.... in the closet.
