    Its not a cooler.....!!!! Thats something you keep your beer in!
    Its a HSF or a heatsink and a fan... (you'll understand if you watch the video)
    The clock divider is cool though. Its something that not a lot of athlon motherboards support. The Iwill XP333 supports this as it is the only way it can run the fsb at higher speeds without overclocking the AGP and PCI (AGP usually a 1/3 divider and PCI 1/4). 150 fsb on a standard 266DDR board means a 37.5 PCI bus which usually runs at 33Mhz. Not all PCI components are happy running at these overclocked rates so user definable dividers solve this. I believe this technology was a long time coming as its not a simple thing to be able to do on a motherboard.

    I agree that AMD boards need to implement this technology also. I thought it was pretty cool how everything was set and the divider took care of all the PCI and AGP overclocking.

    And I thought is was really cool how he simply snapped the heatsink into place. Must be nice, I almost had a heart attack installed my first AMD heatsink!!!

    I know that the Iwill XP333 boards have this type of divider technology. Not sure about other 333 boards as most have only recently been released and there is not that much information floating about the net regarding them.

    I also liked the clip for the P4 "cooler" installation.
    Seems like a much easier system than the cleat socket A method. Although that standard heatsink that he fitted was absolutely massive in comparison to my neat little SK6 on my 1.4Ghz Athlon.:eek:

    Here's another P4 Northwood OC Adventure for you guys:

    I'm glad he is going for more as paying the extra for a 1.8A instead of a 1.6A it seems silly to stop at a 100Mhz greater overclock. I'm tempted to get one of these and put on a quality high performance HSF and see what the 1.6A will go up to... :D

    Very true indeed. But I still can't get over the fact that RC5 rate is horrible on the P4 :(

    BTW, the FSB for all P4s are quad pumped rite?

    Not sure. Never owned a P4. From everything I have read about them it seems to be the case.

    Weird indeed, maybe the heatsink/fan isn't properly installed/working? My P4 1.6@1.9 runs quite a long time with just standard heatsink, fan turned off.

    This is just my guess but I think it's because of dnetc is multithreaded and programmers have forgotten to add pause command to their spin-wait routine.

    Is yours the new Northwood? My friend is using the older core (forgot the name). Perhaps that's causing all the heat.

    Not really, it's due to some number shifting thingy that the P4 lacks. I can't seem to find a link to that for now. But I'll come back to this later :D
