Why Terratec Aureon 5.1 Fun got burned?
Hello,
I've a problem. Some time ago I connected Terratec Aureon 5.1 Fun card to a server (PCI slot). It was universal (5V & 3.3V) card so I thought it would be fine. Card got burned immediately after powering up the server. Pins around 10 (just before first notch if you count from the rear of the computer) were burned totaly (even after 2 weeks you can smell it). Nothing was connected to the card. I thought that the card itself was damaged (or something like that) so I connected another soundcard (identical as before) to another server (again - identical as before). Unfortunately effect was also identical - card was burned. To prevent similar accidents in the future I would really like to know why did it happen? Shouldn't Universal PCI card work with any PCI slot? Or am I missing something? regards & thanks in advance for any ideas t47 |

There are a number of +VIO pins, so more than one could burn. Keying is used to prevent a VIO problem. http://www.interfacebus.com/Design_PCI_Pinout.html http://pinouts.ru/Slots/PCI_pinout.shtml Maybe if the card isn't keyed properly, and the card is 5V VIO only, that's why it happened ? Now if I look at this picture... http://webshop.terratecshop.net/shop..._pci_board.jpg that card is keyed "5V only". http://en.wikipedia.org/wiki/File:PCI_Keying.png If your card has two slots cut, that seems a bit strange. Maybe the card is counterfeit ? The chip on there looks like CMI8738. The datasheet for the CMI8738 makes it seem universal, but I can't be 100% positive about that. The datasheet makes a claim of tolerance, but without the specification section putting it in black and white. I have a spare CMI8738 based card here, not plugged in, and it is keyed 5V only as well.

I've made 2 photos myself: https://picasaweb.google.com/madzion...eat=directlink You can clearly see the burned part. t47 Now, your card says "version 1.2" on it. Other cards have no version at all, or version 1.0 on them. With the exception of the picture you just posted, *none* of them have universal keying (both a 3.3V and 5V key position cut). They all look like this, and are keyed for 5V only. http://webshop.terratecshop.net/shop..._pci_board.jpg A possible reason that particular VIO pin burned, is they removed the other VIO pins, forcing the VIO fault current through the single pin. If more pins were available in parallel, more contacts would have been available to handle the fault current, which is still not a good thing. It's always possible there could be a short on the PCI card, between VIO and GND, and that can be caused by a defective capacitor. But what really bothers me, is the fact your card is keyed as universal, when I can find no other pictures like it! Something smells, like counterfeiting. And it makes no sense to counterfeit a card like this one, when ordinary CMI8738 cards can be made for less money, by simply removing the TOSLINK ports on the faceplate. That saves two dollars right there, and allows a competing card to be made for less. I think it would be interesting, to relate your story to Terratec tech support, to see what they say. If all their cards are keyed for 5V only VIO operation, that card should never have been able to plug into your 3.3V server. Paul |

Fact, that Terratec doesn't even mention it's existence is also quite weird. It seems, that I'll have to contact Terratec tech support through their private info hungry form. I'll post any info I get from them. regards t47 |

Why Terratec Aureon 5.1 Fun got burned?
I contacted Terratec tech support and after few emails they stated
something like: "we don't know why your cards burned, please notice that we do not provide drivers for Windows 2003 server". Since both cards burned immediately after powering up the system I think that the fact that I didn't have any driver installed doesn't matter. Anyway - Terratec Aureon 5.1 Fun was once a 5V PCI card. Then they changed it to universal PCI (I asked when did this transition happened but they wouldn't tell me). I plugged it into PCI-X port with which it should have been fully compatible. It seems it isn't. I provided full info to Terratec about this but it seems that they aren't interested. So for now there's one conclusion - stay away from Terratec products - who knows how many more surprises are still waiting to be discovered. regards t47 |

Perhaps someone else, higher in the company, can shed some light on this. I wouldn't expect them to compensate you for the damage, but at the very least, they should stop production of that thing (if it is actually coming from them and isn't counterfeit). And change the keying, to protect customer computers. When you write them, include a picture of the card as an attachment, with a closeup to show the keying. ******* Years ago, some SIS305 based AGP cards, did something similar to customer motherboards. Burned Northbridges, because of incorrect keying (cards keyed universal, should have been 3.3V only keying). So this has happened before, but with the AGP slots. I've also seen pictures of a Creative SoundBlaster doing this (burn pins on PCI), but in that case, it may have been a component failure, rather than a keying error. Mainly because, the event wasn't repeated. A couple of victims, and that was it. Paul |
