DN2800MT TV card Compatible issue

Hi Intel support team,

 

I found a compatible issue with the DN2800MT motherboard with PCI-E TV card, I had installed a "TechGear HDTVC3 Dual" TV card and found the board cannot boot up (power on the board and noting show on the screen). When i install another TV card "Magic-Pro HDTV Diamond". System can boot up, BIOS can show the device ID and Windows can install driver, however when i start the Windows Media Center and start configure the TV, MCE say there is no TV card installed.

 

Both card were working fine at the moment on my other 2 PC so it is not a card issue.

 

Please help to fix the compatible issue, thanks!

 

Below is the my system configuration

Motherboard: DN2800MT with BIOS 0155

OS: Windows 7 Ultimate 32bit

 

Magic-Pro HDTV Diamond Hardware IDs: PCI\VEN_1131&DEV_7160

TechGear HDTVC3 Dual Hardware IDs: PCI\VEN_14F1&DEV_8852

    That looks like it might be a case of an old PCIe TV card not being compatible with your PCIe x1 slot on your board (as far as the no-boot situation. I recall a poster with a different TV card (which also had a Conexant chip on it) having a similar problem a few months ago here so a search under TV Cards might get you that history. To cut a long story short, the hardware had an issue preventing it from working with the (other Intel branded recent) motherboard and as the card was out of warranty, a replacement (compatible) card was the only option. You could contact the card manufactrer about this one and let us know what they have to say.

     

    As for MCE not seeing your TV card, is that TV card actually Windows 7 MCE compatible and do the other PCs you've used it on work with it in Win 7 MCE or are we talking with its own software only (many cards are not MCE compatible)?

     

    Here's a link to the other post I was thinking of: http://communities.intel.com/message/155615

    I'd hazard a bet that it could also actually be a power supply issue, in the regards that the Cedar Trail chipset (being a low power <15W board) is only able to supply a limited amount of power to the PCIe slot. I know a lot of PCIe x1 Graphics Cards for example won't work on them because they simply draw too much power through the slot than the board can provide.

    A good point as some TV cards can gobble up alot of poiwer. Then again a PCIe x1 slot should be a standardised thing and the board design should alow for the maximum power such a slot is capable of transferring according to official specs. Perhaps the power supply unit itself isn't up to it? Possibly this may explain why one card shows up in device manager but not in Media Center (particularly if opening up Device Manager and checking again while Windows Media Centre is open, shoiws the card has vanished or has an exclamation mark etc). The tech specs for the board may make reference to PSU/Power related concerns if anything is 'non-standard' - I've not had a read but it should be freely downloadable off Intels site under documentation for this board.

    Thanks Flying_Kiwi and powerarmour for the replies, i am using a 72W (16V 4.5A) PSU and i had just swap to another 120W  (19V 6.32A) PSU but the result is the same, so i don;t think it is PSU issue.

     

    The TechGear card is Conexant (CX23885) chip so it may be compatible issue, let forget this card (even it is working perferly on my other MSI 945G, ICH7 motherboard)

     

    The other Magic-Pro card is using NXP chip and it is MCE compatible for sure as i had been using this card watch TV using MCE for 2 years already.

     

    The card did not disapper at Device Manager when MCE is running also. I had attached the screen for reference.Problem.jpg

    My TV Card has an NXP (Philips) Chip on it and these certainly use the power - I saw noticable fluctuations in the 3.3 volt bus with my old 350 watt PSU (on a DG45ID with a Core2 Duo - monitored with Intel Desktop Utilities). Fortunately a more powerful PSU resolved that for me. How do the voltages look in IDU on your board when Media Center starts? If its anything like my TV card, the manufacturer has their own proprietary software to control it as well - if you install that, what happens?

     

    [Edit: Additionally, I took a look at the manufacturers website for this card and near the bottom (thank heavens for Google translate) it reads that the min specs are:

    HDTV HD playback:  ◆ Intel Core 2 Duo 2.5GHz processor or above (in conjunction with support for hardware accelerated display card) 

    So an Atom CPU with low power graphics probably don't stand a chance of meeting the minimum system requirements....]

    Hi Steven,

     

    That's not what I mean, changing the PSU won't make any difference, I just don't think Cedar Trail boards themselves supply enough power to the PCIe slot internally to be compatible with all cards, maybe only ~10W is available (or even less), so some cards just simply won't work.

     

    That's my theory based on what I've read on other forums so far, but I'll be happy to be wrong about it.

    From the Tech Specs for the board:

    "2.6.3 PCI Express* Add-in Card Considerations The motherboard is designed to provide up to 10 W to the PCI Express x1 slot. The total power consumption from add-in boards on this slot must not exceed this rating".

     

    At least this limitation is documented but they should really name it differently IMO to signify it cant cope with normal PCIe x1 power levels. Perhaps the card manufacturer's tech support people can advise typical power consumption figures for the card if Steven asks them?

    Thanks Powerarmour, i mis-understand your advice on power, sorry!


    I google PCIe and i agree with you that standard PCIe 1x slot can provide 25W (normal profile) or 10W (low profile) card, so some PCIe card need 25W may not work. I am not sure how much power did my TV card draw, i call the support team but they say the card is end of life so no more support.


    As per Flying_Kiwi help, the power provided by PCIe low profile slot is 10W so i think the PCIe slot can support low profile card only (which the TV i am using is low profile).

     

    Hi Flying_Kiwi, for the minimum requirement, i think it is not really correct / need as my existing system is:

    CPU: CoreDuo L7400 1.5GHz

    RAM: 1x2G DDR2 RAM

    Motherboard: MSI Fuzzy 945GME2

    VGA: ATI HD5570

    HDD: 1xSSD + 1x1TB

    The CPU does not met the requirement but it is running very smooth (the only problem is it is hot and consume more power (70W), so i plan to change to Cedar Trail boards as it draw less power)

     

    Moreover, i had try to connect a USB TV stick (borrow from friend) yesterday and MCE can detect it and of course can search and play the TV program, the hardware decoding is confirmed working also. I also try to re-install Windows and it is the same.

     

    I also tried to measure the power consumption for the whole system (AC side), with TV card take 23W and without TV card take 18W

    Some cards have changable back plates to enable them to be used in either standard or low profile cases so if your TV card is one of these, it still isn't clear how much power it will consume. Power supplies have varying efficiency levels depending on the currant drawn so your idea of testing the total consumed power with and without the card may not be very accurate. I still think some persistance with the card manufacturer may achieve progress. All you need to know is a power consumption figure for the card so you can decide if there's any hope of getting it to work with this board, it's not as if you're wanting them to exchange your card under warranty etc. It looks like the min CPU power specified may not be strictly a limit but there's still a long way down from your tested core2 duo and an Atom CPU and graphics so this may still be an issue.

     

    It'd also be worth contacting Intel Tech Support and creating a ticket about it. They may have some experience with TV Cards and this board - either from other customer reports or perhaps internal testing? Although a USB TV Tuner may use less power than typical cards, there are disadvantages to going with such an arrangement so I understand if you want a fully internal, card based solution.

    With Intel facing compactibilty issue with up to almost 90% of the PCIe TV Tuner for their latest motherboard 7 series, I suggest those who want to buy their motherboard better buy a USB TV tuner instead as it is a much safer option. I cannot imagine if Intel design their board untill certain USB device stop working, I am very sure everyone will jump because USB device is the most commonly use.

    Btw, something like this would be a definite workaround of the power limitation :-

     

    http://jcl-tec.en.alibaba.com/product/486273929-212706357/PCI_Express_PCI_e_1X_TO_16X_Riser_Card_Extender_Ribbon_Cable_with_w_Molex_Connector.html?tracelog=cgsotherproduct1

     

    Connect the Molex direct to the PSU, and voila...
