I'd say that anywhere from 1.37 to 1.40v set is in the ball park, even with a vdroop causing actual to drop down to 1.38v or so.

First thing to do is run one of the blue screen analysis tools I pointed you to in my earlier post

Second thing to do is run Memtest 86+ overnight or 8 hours and see if it passes

If Memtest passes then you can proceed to harder core stress testing like Prime95 or OCCT

Definitely the above. In my limited experience with FX processors and my friend's FXs, this is the route to go. But a small bump in voltage first might help, my 965 BE experienced what you had, and I increased my NB voltage by a bump and it helped a bit, although it might not help you.

And as said before, vdroop is very common and you shouldn't worry.

My 965be should be at 1.525, but it vdroops down to 1.46-1.475.

As a general rule of thumb I think a small bump to n/b voltage on AMD platforms helps sometimes. Great point Dantron.

Okay my northbridge is stock, im running 4.3 stable at 1.4. I would like to get to 4.5. I am going to bump up one tick in voltage for cpu v core and should i really bump up N/B voltage, if so how much?

so the bluescreen before was caused by ntoskrnl.exe not sure how else to read dump using the bsod program.

Depends on how much your EFI allows to bump, I suggest maybe around .05 more volts.

Strange, that seems to be the kernel barfing on you. As I said before, try the N/B voltage, go try windows again, if it crashes still, perhaps increase the voltage 2 ticks or thereabouts for the CPU. Then run memtest86+ as websspot said.

will do.

Most people would consider a 1.4% tolerance between the SET voltage and MEASURED voltage to be quite good. If you need more voltage, just raise the SETTING and let the ACTUAL follow it up. The discrepancy is not a "problem."

The PROBLEM is when you SET something like 1.40V, and then actually see 1.40V (dead steady all the time) as the "result," because then you start second guessing whether or not you are being fed a lie about the actual voltage. Being able to observe some real world fluctuation in measurements under different loads should actually bring comfort that the measuring equipment is talking to the BIOS and the BIOS is forwarding it correctly, and the OS kernel-modules for sensors are actually configured correctly to translate the output from BIOS.

I even bumped it to 1,41 and it still stated 1.38 max voltage in CPU id but comps running good so no complaints gonna stay at 4.3 stable for now. 1.2ghz over clock I'll take it
