Possible VIO issue with Abit BP6

[Pinky]

I am not sure about anything when it comes to the schematics of this motherboard. I had some training years ago in electronics, but lost much of that knowledge to pot smoking and daydreaming...

I think the voltage drops on my board have been causing lockups when the cpus are at full load. In the bios, I can watch the VIO and core voltages rise and fall +/- .02-.04 The VIO fluctuates around 3.20, but that seems low. i was wondering if I took the time to increased it, would I see any improvement? Right now CPU #1 is @2.20v and #2 @2.10v seem to run stable, but I'd like to get that 2.20 down (these CPUs have been overclocked for about 1 year, so they're plenty burned in).

Its common for some boards to get this fluctuation.
I have been told that its due to the use of cheap voltage regulators.

Here is a link to a thread about it.

Thanks for the thread, that eliminates my worry and as a possible cause for my prior lockups.

I have had this same problem on my BP-6. Even with all my drives and extra fans and the machine hooked up to a UPS, it still did it.

I think the "cheap regulators" is probably valid, as its the only explanation that I can come up with.

My Abit BE6-II is always fluctuating about .02 volts up or down. The Vio seems to be a bit more stable then the Vcore. The Vcore is also almost never exactly what I set it to. Like 1.9Vcore is between 1.87 and 1.89 Volts. It doesn't seem to be causing any instability at all anyway. (I have a 300Watt PSU)

What I have finally, after a week of troubleshooting, did was up the VCore of the CPU running the coolest under full load, which just happened to be CPU0 (the first one used most often), to 2.20V and left CPU1 (the second) at 2.10V Thus far all is well, probably because I haven't been playing much UT!
