Okay, for arguments sake I ramped up and tested the system on some of the highest voltage settings.
If I put the vcore voltage to 1.6 volts the system blue screens. If I bring it back down again it's happy. In testing voltages between 1.3 - 1.5 there is absolutly no difference. I ahd previously tested these settings overnight and found them all stable up until passsing the 333SB level. It's interesting to see that the system became unstable if the voltages went too high.
I also tried putting up the voltages such as MCH to their highest levels (1.85). Again the system is okay until 333 FSB and then unstable past that.
I'm just going to have to accept that either the motherboard or the CPU is limiting the overclock. I have worked in the electronics world (design and manufacture of PCB's, robotic board manufacture etc.) for 15 years. It is extremely unlikely that a chip will work to a specific level and then completely not work at a very fine different level. There is always a grey area in between when chips get flakey. My system is telling me that there is some other outside influence making the 333 - 334FSB limitation. I just wish I could figure out what it is. I've checked and rechecked that all the components are properly soldered, seated, etc. There just can't be something about my board that would not show up on other peoples boards to make this specific limitation.
I forgot to add that the temps under load were in the low 50's
Arrghh
