A8V voltage questions...

[Ironwolf61]

Just wondering about my motherboard doing some wierd things lately. I
have had this system for about a year and it's been real stable until
now. I was going to get a 3700 San Diego CPU so I went and upgraded
my BIOS to the latest and greatest; 1014 from 1008. All hell started
to break loose, lockups, blue screens. Rather than fight and try to
see what values I needed to change, (nver had to do that on my older
BIOS's change) I went back to 1008. Had to reset my CMOS and I thought
all was okay after I verified and changed my setting to the proper
value. Nope, I've been having an occassional freeze which I can only
clear by a power reset...

Okay now for the power question, using ASUS Probe; I have seen my
VCORE setting vary from 1.454 to 1.486 (sometimes 1.512) . The
hardware monitor shows it to be 1.504 to 1.536 . I see VCORE swinging
with Motherboard Monitor as well but it's reading what the BIOS
monitor is reading...My 12V is also swinging from 11.904 to 11.968...
I am hoping it's not my regulators on my motherboard...

Any help would be appreciated as to why I am seeing these freeze-
ups..

Forgot the most important component,,, AMD 64 3500 (130nm) set for
1.5V in the BIOS

did you on the first boot following the bios upgrade/downgrade, did you go
into the bios
and setup the defaults then reboot into the bios and set it up the way it
was?
If not try it.

Lets assume a tolerance of 5% for the 1.5v core voltage.
1.5v +/- 5% = +/- .075v
So that is a range of; 1.425v ~ 1.575v
and your range of; 1.504v ~ 1.536v is within that tolerance.

Lets assume a tolerance of 10% for the 12v voltage.
12v +/- 10% = +/- .12v
So that is a range of; 11.88v ~ 12.12v
and your range of; 11.904v ~ 11.968v is within that tolerance.
if you assume 5% tolerance...
That yields a range of; 11.4v ~ 12.6 and again your range of; 11.904v ~ 11.968v is within
that tolerance.
And those are all "loaded" voltages.

The only thing not measured is the ripple on the DC voltage and you would have to use a DMM
for that.

I don't think you have a power supply voltage problem.
