Re: Do I Have Bad Caps?

Yep, they're dead or failing Taicon caps...

Re: Do I Have Bad Caps?

Oh well. Now I know they're failing. Gah. How likely are they to ruin my other components while I buy a new mobo?

Re: Do I Have Bad Caps?

You can try a recap... I just successfully completed my first one and it wasn't all that hard... as long as your a little familiar with a soldering iron. Those particular caps probably won't ruin any components, but if they did, it'd likely be the components immediately surrounding them, like the AGP card or the first PCI card. Hard to tell, but usually they keep the runs from the caps to the components short, so the damage is localized.

BUT- it'll probably just keep running, and maybe get more and more unstable. What are the other caps on the board? Oh, and if you decide to just replace it, I'm sure someone on here would be happy to take the damaged board off your hands

. Also keep in mind, it could still be under warranty.

Re: Do I Have Bad Caps?

I'm sure I could do a recap just fine, but I don't really care for this mobo anymore. It was cheap ($35 or something) and I've actually been thinking about getting a new one. I'm probably going to get a DFI. I built a system for a friend with a DFI Lanboy and man that was a nice board. If you want it, I guess I could ship it to you.

BTW, if the caps fail completely (if they haven't already) what happens? Does it ruin the board or components nearby? Or does the board just no longer function?

Re: Do I Have Bad Caps?

I don't really want the board, as I don't care for the P4 processors, but someone else on the forums here would take it for sure if you don't want it. A recapped board can sometimes be even more stable than new when using quality capacitors, but that's really up to you.

As for what happens when caps die, it really depends. I've seen motherboards with all but 5 caps pushed up and leaking, and they jsut stop posting, but I've also seen boards with mosfets blown to pieces and ATX power connectors melted and browned. it really does depend on how the board is designed and how the caps fail. I've had three Leadtek K7NCR18D motherboards die of bad caps, and every time it melted the 12v pin off the ATX connector, trashing the board and the PSU, but luckily none of the other components.

Re: Do I Have Bad Caps?

If you don't want the board, I'd be interested. PM me with details.

Re: Do I Have Bad Caps?

how long have you have that board running for? did it always have a prescott on it.

interesting to see Taicon caps fail, it is the first report we have received, so thanks for that. They appear to be 1000uf 6.3v right?

**Newbie2** · 01-19-2006, 01:30 PM

Re: Do I Have Bad Caps?

A long time ago I think we thought Taicon caps were not affected.

Is Taicon going on the list or we're waiting for more reported failures?

Their site: http://www.taicon.com.tw/

I don't know why they say "Nichicon Family" under the Taicon logo.

Re: Do I Have Bad Caps?

Shit!!!

I have an Intel SAI2 Server Board that is packed with those Taicon bastards............... I guess its time to inspect, cuz its embarressing for the Admin of badcaps.net to have a board with bad caps...........

**willawake** · 01-19-2006, 02:49 PM

Re: Do I Have Bad Caps?

get some esr readings, would be interesting.

Taicon was established by nichicon in 1969 as a joint venture

actually we have another failure on the forum reported by Codecode on 19/11/05 for an ASROCK K7S8XE + which i had missed previously

The brand that has swelled are around the ram slots and the AGP slot, away from the heat, and they are TAICON caps, green plastic sleeve, all 1000mfd/6.3v.

Taicon is actually not a very common brand on boards. I had only seen them on my asus P4B266-E and was suprised they were used on Topcat's Intel SAI2 board. Now we see they are also on Asrock boards. There is still nothing much in google so no widespread fails. Anyway two fails are good enough for me, to be on the bad list.

Re: Do I Have Bad Caps?

The power supply in my Dell Dimension 4600 is failing in some manner. Either the fan (Adda 80mm ball-bearing type) is failing (possible yes, probable maybe), or the 12v supply is failing. The two primary input caps are Rubycon, but the secondary is full of Taicons, with two Ltecs. None of the caps show visible signs of failure. The power supply was made by Newton Electric. Pictures will be posted in the power supply build thread.

Re: Do I Have Bad Caps?

Maybe Taicon screwed up some series - like Nichicon? I've had 1995 monitor full of Taicons with no problems.

**kc8adu** · 01-19-2006, 06:31 PM

Re: Do I Have Bad Caps?

iirc that sai2 was new when i got it.guess we will see if the caps go t/u.

I have one running in my office with dual P3-T 1.26GHz. So far no visible failing signs, but was quite well cooled for past 4 years.

It's a pain to recap that board, with well over 30 caps.

Re: Do I Have Bad Caps?

I don't think that's problem of Taicon capacitors. I think there is some problem in design by Asrock. Actaully, i know the quality of Taicon capacitors is not bad.

Everyone should know Asrock motherboard using with Japanese capacitors. Actually, there is no problem and good. However, the main problem is they used with too little capacitors to cut costs of motherbaord. By this reason, i think it is design problem.

Re: ASRock P4V88 with bad Taicon caps

Finally....after a week of trying to figure out what the heck was wrong with my computer...finally after doing everything I could to try and make my system stable again I stumble upon the answer to all the frustration my pc has put me through this week.
Same exact motherboard, same exact problems (except mine usually doesn't stay up for more than 5 minutes) same exact bulging of the capacitors on my Asrock P4V88. I will admit I haven't been as good as I should about cleaning the dust of of the system, but my case has 5 fans on it (Prescotts are hot chips), and there are two on my psu so I figured it was pretty safe from overheating. Was a great motherboard for the year and a 1/2 that I had it running and I would buy Asrock again if I wasn't afraid of the same situation happening.
Thank you for finally confirming this and putting an end to my endless troubleshooting.

Re: ASRock P4V88 with bad Taicon caps

well if the caps are gonna blow then they will do that no matter if the case is well cooled or not. they will probably just do it faster in a hot environment.

are you gonna repair the board?
