VP6 Capacitor Problems source?
Claude Tamplenizza
I've been using a VP6 board with no troubles (since I stopped using the
HighPoint controller) but I've bee reading in this and other forums about
capacitor problems with this board.
My question is:
What brings about these problems, ie what causes the capacitors to fail?
Is it inevitable in the course of time or will overclocking, poor
maintenance etc do it?
Specifically, I'm looking for information on how long this board has lasted
without such problems.
So if anyone here has had a VP6 for years without this problem I'd
appreciate some feedback.
TIA
Claude.

Hello Claude,
I have had several boards, including 2 VP6s, fail with the capacitor problem
and can find NO correlation between the failure and the operating
environment.
More specifically to your point, I have a VP6 that's going on two years of
continuous operation 24/7 and shows NO sign of cap failure. This board runs
a pair of P-III 1Ghz. processors overclocked by slightly more than 11% ...
the FSB runs at 148. Oh, and let me add, the CPU runs at a constant 100%
according to Task Manager and has been at that level since day 1.
Go figure.

"Subsequent reports suggest that Rubycon Corporation, Nichicon, and Nippon Industries
(NIC Components) have been inundated with orders for low-ESR aluminum capacitors, as
more customers shy away from Taiwanese-produced parts. Rubycon, Nichicon, and Nippon
Industries (NIC components) do not have plants in Taiwan, and thus "
No wonder I am having such a hard time getting caps the past few weeks !!!!!!

Bullshit, this is either a big assed lie or their capacitors are failing just because
they sold junk to Abit !

What can I say but THANKS GUYS!
This is obviously a hot potato out there....
Thanks to everyone for the information, I can sleep easy (for now).

Oh MY!
What you said.

Qed.

It is a hot potato!
This newsgroup has been filled with guessing and accusations regarding the
very high failure rate of filter capacitors on many brands of motherboards.
Just this morning I received several e-mails saying " have you tested the
ATX supplies to see if they caused the failure " ............
Yes, I tested ATX supplies about a year ago, after several types of tests
concluded that there was something wrong with the low ESR caps
themselves.....even so, some posters claimed that something else must be
causing the problem and some even claimed that the problem doesn't
exist......

Techie
trade.
I have plent experience with bad caps though.
If you want these boards to run stable you should buy only Military Grade
Capicators and Replace ALL the Electrolytics around the CPU aera.
Why???? because they will hold up better. they are rated to 105 degrees
Celicius.
and can handle the high frequencies better.
I have repaired many switch mode power supplies, and its always the caps
that
are close to the high frequencies that crap out.
i suspect that since these cpu's are in the 1 & 2 Ghz range,
there should be a very high quality caps in the circuit.
of course without a schematic its pretty tough to know how things are set up
in here.
but im sure a high frequency & shitty caps are the cause of failure.
Try calling Universal semiconductor 1-800-222-2321
Make sure you know your Cap Values. IE Micofarads & Voltages.
And make sure you ask for Military Grade Caps.
Another Source is Mouser. www.mouser.com
And you will need a good hot soldering iron and a good solder sucker
the mo-bo's are multi layered and its hard to get the solder out of them .

I was an unbeliever at first
I have 2 abit boards that have this problem
The first one that went was a SH6 with a P3 800EB.
It started with random lockups I finally opend the case
to change somthing and noticed all my caps looked funny
they had all puffed up and some were leaking a little on top.
I just assumed it was some sort of freak failure
I tested my power supply no problem there
so I just assumed some voltage regulator on the board
had gone bad and killed them.
Then a couple of months later my old BE6-2 with a 1 gig celeron went
that got me looking It had only 3 caps that were showing signs and
they were also getting hot.
I decided I might be able to fix it so i started looking for parts
in the process I came across that article about the bad electrolyte
I knew that had to be it.
then I started scanning the news groups and took a look at Homies page
to see many familiar pictures of bad capacitors wow I had no idea
how big a problem this was
Any how I have already orders some Panasonic caps
I got the 10v 1500uf
and now im wondering if i should replace all of them
or just the three that were already bad I guess if i
do just the 3 the rest may go bad later and i will have to
take it apart again
what do you think
ziggy
His tips sonds good to me.
Tell me something. When was the last time you tried to
de-solder something from a motherboard?
its not that easy. You need a small tip, very hot iron.
How can we tell if we have these "Defective caps" ?
Is there someting on the cap we should look for?
how do i know the caps you are supplying are any good either?
Perhaps they were made with the same batch of "bad electrolyte".
How do you know?
Homie
My question is regarding what the poster does for a living now?
You see I have been a VCR tech for almost 30 years and will soon be switching
occupations because it's no longer a viable career.
" Tell me something. When was the last time you tried to

I have possibly soldered and de-soldered more capacitors on Abit motherboards than
anyone except the Abit factory assembly line ........... 12,000 that's right ! 12,000
(3 zero's after the twelve ) capacitors replaced in the past 9 months!!!!!!!
Have you seen my web page?
Have you even read any other post in this group ?
" How can we tell if we have these "Defective caps" ? "
Go to my web page and read !
E-mail me !
" Is there something on the cap we should look for? "
Look at my web page!
" how do I know the caps you are supplying are any good either?"
I use capacitors that are manufactured in Japan and have a well known track record,
not cheap Asian " knock off's "
" Perhaps they were made with the same batch of "bad electrolyte".
How do you know? "
They would also be failing by now, not one board that I have repaired has come back
with capacitor failure!
The last 2 questions indicate that you know who I am and have been to my web site, so
I can only assume that you are trolling ?
That's ok, we like a good trolling now and then, got any sheep?

I wish I had found your site first It would have saved me
a lot of time searching I had already found the Panasonic
caps & decided to buy the 10v 1500uf ones before I found
your page.
Seeing that you were successfully using the same part
gave me a lot more confidence that it would work.
If I encounter any more bad boards I will get the caps
from you next time.

100% ?! Oh yeah... you must be running Windows. :-)
