I have just brought my latest BP6 into action. It took me quite a while because I wanted to find coolers that could fit on the Celerons without lying on top of the ZIF lever (the metal type that sticks up). It took me quite a while but I managed to find older Q-Tec for older socket 360 and Socket A processors.
This board was absolutely spotless when I bought it and the caps were all in mint condition (to the eye at least). What I decided to do was to do only minimal changes to the board and seeing how far I can get with overclocking without risking stability.
So the only change I did was to change Q6 and putting a large passive cooler on the BX, along with the Q-Tec coolers:
And I haven't even updated the BIOS yet! I am running 2x366MHz@550MHz (see my new sig).
So how is it turning out? Well, the voltages are rock stable so the caps must be doing a decent job. The temp between the cpu's is 1-2 degrees apart at the most but I am not too worried about it because it could also be caused by something like the sensors being different distances from the CPU's themselves. Here are my sensors reading (the computer is idle):

My CPU's are not all that happy at 550MHz though. I have also tested them on a caps modified BP6 and didn't get any better result. Linux kernel panics if I use 2.0 volts. The board boots at 2.1 volts but it will be flakey. At 2.2 volts the computer boots and works just fine. I did run a CPU burn-in test and it ended up freezing the board after about 7 minutes. It was a bit strange though since the temperature had stabilized at around 46 Deg. C. so I was hoping it would pull through. I am pretty sure that it is the CPU's that are simply not happy at this speed. I have had them running with 100% stability at 523MHz though so that is probably what I will end up doing. I want to do some tests first before I clock it down though. I guess my sig. will end up showing how things will end up. I might try to get my hands on a couple of 366's that can run at 550 without raising the voltage if I bump into that somewhere.
