Linux friendly hardware guy?

[Jose A. Dias]

Not bad numbers, but two of them are *very bad looking* to me. Here's a
little table I put together:

	Reference	-5% Range	Actual	+5% Range
Percentage from spec
	1.5		1.425		1.58		1.575
105%
	1.5		1.425		1.58		1.575
105%
	3.3		3.135		3.26		3.465
99%
	5		4.75		4.92		5.25
98%
1)	12		11.4		11.46		12.6
96%
2)	-5		-4.75		3.64		-5.25
-73%
	5		4.75		4.87		5.25
97%
3)	6		5.7		4.08		6.3
68%
 

Here are some comments on the above:
 - Number one above (1) is just within spec. By it self that does not
mean much, but let's see the rest.
 - Number two scares me! Are you sure it +3.64? That should be the -5V
line.
 - Number three is very motherboard dependent. I *think* it should be
6V, but I could be wrong. This by itself does not mean anything,
specially if the bios settings are sticking. Change something in the
bios, power down the machine, and unplug it. Check again in an hour and
see if the settings stayed or have reset.

Even if the polarity of number two above is corrected, it's still only
running at 73% of nominal. No motherboard is going to "work" with these
numbers.

Try running the utility, and even some other utility, a few more times
to be sure...

A new power supply *is* a good thing!

My bios doesn't show the voltages, but I found a freeware Windows app 
called Speedfan that shows them...I'm seeing

Vcore1  1.58V
Vcore2  1.58V
+3.3V   3.26V
+5V     4.92V
+12V   11.46V
-5V     3.64V
+5V     4.87V
Vbat    4.08V

Looks like a fair bit of variation. I guess I'll have to get a power 
supply when the stores open up and try replacing that.
