Well I need some help. Since I have O/Ced my B&W from 400MHz to 450MHz the CPU temp has risen 10 degrees higher and I have started to get some system lock ups. Funny thing is this hasn't happened untill yesterday. Would a new heatsink cure this problem or have I started the slow death of my B&W? I can always trip off the bottom drive bay where the ZIP drive use to be connected to and move the HD I placed there to one of the drive mounts on the bottom of the case and just do some minor surgery on the IDE cable so the IDE connection can reach the HD. When I had the system's guts in a ATX case for a while there I had a old Socket A heatsink on it but since I put the B&W's guts back in the B&W casing I can't close the case with the socket A heatsink with the zip drive bay there.

maybe josh's mod will help you out.

doesn't help. I pretty much did the same thing josh has done before his guide got posted.
The only major diffrents was when I had my B&W in the ATX case I used a 80mm fan. Since it placed it back into the B&W casing I just poped on a fan from a old Intel 486 heatsink with the old stock heatsink that came with the B&W. Also on my chipset have two small heatsinks and fans that I riped off of a old 3DFx voodoo 5. Also I have the artic ice putty on the heatsinks. Trust me I have added heatsink all over the system. It's just I don't think the stock heatsink can't withhold the temp right. Or maybe my B&W is slowly dieing. Not every B&W CPU can be overclocked to the same speeds. I'll just try the little idea from before and see how that goes. If it doesn't work i'll just go back to 400MHz or just go and buy a CPU upgrade.

Is it a rev 1 with the small heatsink? You could always put a pentium fansink on it. How bout some H2O!

It's a Rev2 B&W system. The small pentium heatsinks won't cut it.

The pentium runs much much hotter than you G3, Im sure it would solve your problem. If not, than the chip just isnt going to live at that speed, as most wouldnt. If you can get it to run that fast for the long term, there is still electro migration and shortened lifespan. I couldn't even get a 350 to boot at 450 when watercooled without out a voltage mod. Even then, the cpu went to computer heaven. Good luck. Keep us posted on your findings.

Try a decent socket 7 cooler (if you can still find one!) and some good quality thermal paste.

Socket 7 and Socket A use the same size heatsinks. I just got done choping up my B&W and added the socket A heatsink. Now I just have to sit back and wait, i'll try playing some Warcraft 3 as a test.

Well it hasn't forze up and also the temp seems to be in a good range of 98*F. When the stock heatsink on it was about 112*F.

Wow, looking at these heat levels, I am wondering if my temp monitor is screwed up or my iBook is too hot; my iBook gets up into the 150? F range :ohmy: That's pretty hot, no?
