VP6 voltage problems? *GOT A SOLUTION*

Here's the deal. Got my VP6 today. Plugged-in all the cards and figured I would try to hobble it into my old install of Win98 when I had a KT133 chipset mobo in before. Via chipset to a different Via chipset. Should allow me to get there. I turn on the system, not a problem in sight. I even pushed my 700 cc0 up to 1001 MHz at a fsb of 143 and it didn't care. Backed up everything I wanted, not much because I already took the precautions if it didn't happen as well as I planned.

Anyway, after a clean install of Win2k prof. and setting everything up, I can't get SMP GHz action to work. I installed mobo monitor5 to check the temps and low-and-behold, only one of the processors are running at 1.85v while the second proc is only running at 1.65v. I am amazed that I can get 966 MHz out of the pair right now.

I don't know how to increase the voltage of the second processor to achieve the dually GHz mark I am reaching for. I know that my ram can handle it and I bought the processors matched from a gentlemen that tested each individually up to 1017 using seti and prime95 for 12 hrs a piece for stability testing. I know I can get the extra MHz with a voltage increase, but how?

I am still trying to squeeze the juice from these guys. I managed to get into Win2k at 141x7.0 = 987 MHz. Closer to 1001, but not close enough.

I was informed that they could be mixed procs, a cc0 and a cb0. I checked via cpu-id and cpu-z. Both agree that they are matched, either 2 cc0 or 2 cb0. I am willing to believe that they are what I originally purchased, 2 cc0.

I am still trying to figure out why they aren't matched up for voltage. They reason I persist that the voltage isn't increase is because the voltage and temperature of the processor is lower than the other.

Cpu1: 31C 1.65v
Cpu2: 39C 1.85v

The voltage and temp make sense that they aren't increased. If the temps matched, I would write it off as a glitch in the prob or program.

I finally received an answer to the temp and the voltage discrepencies.

The voltage is MBM5's fault. The board can only display the voltage once, not twice. Something to do with the way it is wired. The program tries to read a second voltage that isn't there and defaults to 1.6v

The temp problem: The probe is bent further away from the die and is picking up a lower temp than the one closer to the proc.

still doesn't explain why I can't get over 141 MHz fsb!
