Re: mobos with japanese caps only

Reddish brown, but they aren't that early of a revision. They're V2.0.

Here's the weird part. I had three of them that I could grab quickly, and all three have different caps.

1 is all rubycon, including the 6.3v 1000uf between the AGP and first PCI that goes boom.
1 is all rubycon, including the now replaced Nichicon that _did_ go boom - but only in the 10mm caps. The 8mm caps are all KZG.

1 is all rubycon, but has aluminum cans by the mosfets. One tilted - but that looks more like bad soldering. - HD J2 1200 16v. (well, I actually don't know WHAT brand they are. They have a lopsided oval and a black slash, and that's it)

The other have all been put into systems and seem to be working fine. I made out like a bandit on that one. $3 of caps, if that, and I had six or seven boards back up and running, using up every extra AMD proc I had.

Yeah, that's the newer color I was trying to refer to. The early ones are more yellowish brown.

2nd page shows some cheap Vcore caps on the old revision.

The number of capacitors around the CPU socket has been reduced from 6 to 5 and their location has been slightly changed. We also found that ABIT changed the manufacturer of both, the mosfets and the capacitors between 1.0 and 1.2. It is unclear what these changes are about, but we hope of course for the better.

heheh.

I have several dead Intel boards in the bin. None have premium caps, most are populated with middle of road Japanese, and enough Chinese to raise some consternation.

Chinese caps on an Intel board?
-
Like what Chinese caps?

Here's the weird part. I had three of them that I could grab quickly, and all three have different caps.

That's common with with rebuilt previously RMA'ed boards.
The repair depot will use whatever they can get on short notice and then they get used as factory replacements of sold as re-furbs.
-
Those might have been rebuilt due to the HM/HN fiasco.
HM/HN are good caps except SOME manufactured from 2002 through 2004 during which time one of the shifts (or factories) was screwing up the amount of electrolyte they put in.
-
It happens too with supply shortages during a production run, between different factories, or even between shift changes if shift supervisors are given options.

That's just it. The company that I got them from doesn't do refurbishment, or sell refurbished boards. There were also far too many of them to say that a customer came in with seven or eight identical machines that he'd built from Fry's parts.

The sets are just strangely... off. It's like they did three or four runs of the same board, perhaps, and kept running out of parts

Re: mobos with japanese caps only

If the factory was using HM/HN for these at the time the problem was discovered they were probably scrambling to get whatever they could get their hands on.

Refurbed boards that don't get used for replacements get sold off in huge lots when the model gets phased out of the support cycle. - As in by the pallet. 20 boards to a box. Some get OEM packed. Some get 'brown boxed'. Some even get retail boxes if they have left over boxes to get rid of.
-
That's one reason why eBay occasionally gets flooded with certain models of older boards.
-
Some not so honest (or not so bright) dealers call them as "new" because they did come from the original manufacturer and they don't admit (or understand) the difference.
-
Other times the manufacturer causes the confusion by calling them over-stock (which they are) but without mentioning they are also refurbs.

I'm not contradicting what you say these are. (I wasn't there.)
-
I'm just saying there's a lot of situations where a dealer might not admit (or even know) that the boards he bought and is reselling were rebuilt.
- And that this can easily happen in lots of 20 to 100 (or more) boards.

Re: mobos with japanese caps only

Nah - these were even in the original retail box. I know the company. They want to make lots of money, but they order from the manufacturer directly, as I recall (or did).

Doesn't matter much, does it? I didn't have to pay for them

Yes, Free is good.
