List of bad caps?

[hyperjer]

Is there a list of cap makers that made crap parts? or a list of caps known to fail? this would be good for people to know when buying a new motherboard

I don't agree good motherboard = using good caps. Although capacitors is really importance, but design is also more importance.

For example, Asrock is using good caps, but Asrock is not good motherboard choice.

Re: List of bad caps?

ASRock are budget boards. Expect budget boards like PCCHIPS, ECS, and ASRock to be the best?

All are the cheap motherboards. I will choose ECS if i must choose one...... :

Re: List of bad caps?

Capacitors are not everything.

Look at Asus, they used to use Japanese caps, now they use some unknown Taiwanese caps, but still they can provide you with a stable environment. OK, some new Asus boards has really crappy caps that explode due to high heat from the CPU, just get them replaced, and it's good again! Thanks to the high quality of Asus BIOS design, PCB design, manual design, tech support, etc.

Now look at Jetway. After being (insert word here) in the (insert word here) multiple times 24/7 for using bad caps, they now spend more money on better quality caps. Good! But now, since they spent more money on better quality caps, they spend less money on connectors, BIOS design, PCB design, QC, etc, causing problems in the long run, for example: unstablity, down systems, CPU/RAM has to be reinstalled because of bad contact in the cheap RAM slots, CPU slots, etc. they use. Bad, bad, bad!

Real life example:
In HKEPC forums, there was a trend of using ASRock motherboards, "savior of the poor people", and now there are many cases of the motherboards suddenly dying with no burnt components or blown caps, right after the 1-year warranty expired :P

P.S. ASRock uses Japanese caps.

Re: List of bad caps?

I've seen Asus boards with really bad PCB design - CPU bus lines right next to MOSFETs, VRM chip as far as 10cm away from one MOSFET (it was A7V8X-X IIRC). Asus boards are no longer that good as they used to be (e.g. P2B series).
I like PCPartner boards (they're sold as various brands including SuperGrace) - they're cheap and reliable (except for the Licon caps...)

All Asus motherboards' model number with the letter "X", that's mean cheap and cut cost series. So, bad design is normal.

you got that right.
i have seen some real shoddy pcb layout on motherboards.
mostly pcchips,a few ecs,and even an asus.
also stuff like crap nb fans,heatsinks that are not flat and no compound used,onboard sound subsystems with no bypass caps nearby so you hear racket in the speakers from the hdd spinning/accessing.

Good grief! Weren't IC sockets for the RAM part of what killed the Apple III back in the early 80s?

Re: List of bad caps?

Some older PC Chips boards have weird PCI and DIMM slots - it was almost impossible to put a card/memory module in, especially for the first time. But once it's installed, it works fine.

I disagree with this one. They actually appear to OC good.

I cordially disagree also. The X-versions of most Asus boards I've seen are merely "lite" editions, with visible silkscreen spaces on the PCB in which the "full" edition would have installed ICs supporting such 'optional' functions as firewire, etc.

Re: List of bad caps?

No, that's not generally. It's true for SOME of their boards - e.g. Asus P4PE-X has the same PCB as P4PE but some components are missing (not only the optional ones but often some caps and MOFSETs too). And what's worse, many of the -X boards do not have ANYTHING common with non-X of the same name - the PCB is completely different (P4S8X-X vs. P4S8X). There are some optional parts missing - but there is no board with the same PCB that has all the parts installed! I don't know where those PCBs came from...

Re: List of bad caps?

Hi Rainbow,

You're absolutely right - I stand corrected (I had overgeneralised on seeing the lack of difference between an A7V600 and its -X which I had used in the past).

As for the P4S8X-X, it is indeed strange. Perhaps there's an ASRock board that looks something like it? I'll take a look.

...

PS. No ASrock boards are at all even vaguely similar, it appears. The PE PRO sure has quite a bit of empty space though!

Re: List of bad caps?

Maybe they use PCB that was designed but never used as "full" board because of some (design) problems?
