Dead Epox 8RDA+

I tried to state that its kinda random where it fails in the post. One time
its C7, another its F8. Even if it was consistent, the manual is less than
descriptive in what might be wrong.

I did not know the 8RDA+ had onboard video.

You might want to check the board for leaking capacitors.
The 8RDA+'s produced in the end of 2003/beginning on 2004 seem to be
'ripe'.
Google for 'leaking caps' to get some pictures of examples what a
leaking capacitor looks like.

Honestly I may be mistaken with the board model. I don't have the info with
me, but its an nforce 2 board with 400 fsb support and onboard video. Its a
weird version that takes a while to dig up on the site. I didn't notice
anything obviously wrong with the caps, but I can double check later.

8RDA+ don't have onboard video. You have it confused with 8RGA+.<!-- ~MESSAGE_AFTER~ -->
 >> Stay informed about: Dead Epox 8RDA+ 

I had similar problems with my 8RDA+

During a case switch I noticed a few "bulging" electrolytic caps ( 1000 and
1500uF if my memory seves me right.)on the board between the AGP and memory
slots
so I replaced them and "voila" no more problems!!!!!

Y'all might like to check your "caps" just in case!

I thought this caps problem would had passed when I bought the 8RDA+ .

HTH,

Where can you buy new caps? any local hardware store?

I assume you just unsoldier the cap and soldiered the new ones back on?

Hehe, hardware store? Not caps. More like a hardware store.

I bought the ones I needed online from Mouser electronics. You should
buy the low impedence ones (low ESR). The 4 2200uf caps near the
power supply were the ones that went bad on mine. All the others were
fine.

The ground plane unsolders easily but the positive plane is really
thick and you need a lot of heat. I had access to a desoldering
station so it was easy for me but I would think twice about it if you
don't. I have heard people having success with two soldering irons
and preheating the board first. It's not as easy as it sounds.

You need to use the same type of low ESR, high temperature caps.

Yes - after cleaning the caustic electrolyte off the PCB and then
thoroughly
drying before fitting the new ones through the plated-through-holes
and soldering.

Oh wow, damn, sounds like fun.

Anyways, an update on the situation is that I couldn't see any obvious
leakage or bulging caps, so I think the onboard went or maybe the ram. I
always questioned that ram anyways. I'll post an update if I can get it
fixed over Christmas break.

Out of curiosity, any recommendations for a replacement?

I have an 8RDA+ with bulging capacitors and can't afford the downtime
to RMA the board, so I'm thinking about blowing a little money to
replace. I have an 8K9A7I in my HTPC, so I'm leaning that way in the
interest of standarization. (Don't need whiz-bang audio; will miss
the FireWire...)

I replaced mine with a Epox 8RDA3+ (firewire, s-ata, etc...), but it
looks like they're not available anymore. I found the stripped down
version (8RDA3I) at Newegg for 56 bucks (no firewire, s-ata, etc...).

<a style='text-decoration: underline;' href="http://www.newegg.com/app/ViewProductDesc.asp?description=13-123-208&depa=1" target="_blank">http://www.newegg.com/app/ViewProductDesc.asp?description=13-123-208&depa=1</a>

I'm very happy with the 8RDA3+, and used the repaired 8RDA, and the
1700+ pulled and replaced with a 2500+ barton, for my linux
firewall/router/web server/mail server box that resides in the closet.
