    PIII450 @ 623 HELP

    Hi, Ive managed to get my PIII450 (SL35D) to 616 on my Soyo 6BA+IV, with a Dual Overkill cooler from 3DCool on CPU. It runs rock solid at 616, but will also post at 623, 630 etc. However, when I run 3DMark at 623 and above, the system locks up after an hour. I beleive this is heat related? I have a Voodoo 3 with a fan stuck on the heatsink and one on the rear. Also fan in front of case. Will putting a couple of extra fans (1 in side and one in top of case) help the problem? or can anyone suggest anything else? Also what effect does turning precharge on in the bios have?

    For sure it's a heat related problem but don't you think you've clocked it enough? You're already running at 616 MHz... that's a 450! It's okay now!

    Fair point Toolbox. 616 is good for a 450. I guess I was just trying to push it further because it was teasing me into nearly working at higher speeds, and after reading the "with love from intel" article, I thought it might make it. I tried it at 630 with the case off and a desk fan blowing onto it to cool it and it still locked up after about 30-45 mins, so I guess it just aint gonna make it. Thanks anyway.

    I still think we're lucky as hell to have these 450's that go to 600 MHz.

    Have a nice day!

    I'll let you know if I ever decide to push my chip past 600.

    Do you guys think that removing the backplate from the CPU will help? I think they keep in a lot of heat. How would you hold it on? As it is a heat problem, any more suggestions?

    Removing the blac back plate will help immensely/ however/ there goes the warranty. Put an alpha on it/ and you will be stable. Put a peltier and a cold plate on it, and if you have the juice to run peltier, you may well hit 675 like i have .
    Help me get this Boot outta my azz!!!!

    Im not sure if an alpha or peltier will fit with my Soyo board. I don't think there is enough room between the slot and the ram. If anyone knows for sure or has tried let me know. If I remove the back plate (Im not fussed about the warranty, its a bit late now) how should I secure the heatsink?
