ASUS P5K compatibility problems with SAPPHIRE HD6670 1GB.

Hey all,

My Specs:

ASUS P5K motherboard ---->latest Bios updated (ver.1201, year 2008)
GC RADEON 2900XT (512MB)
Windows Vista 32
Power Supply Zalman 600W
4GB DDR2 RAM.

The problem:

The above configuration has been my work horse since 2007 with no problems whatsoever. I decided to upgrade my GC so i bought SAPPHIRE RADEON HD 66700 1GB. I removed the old card, installed the new, in the same PICe Slot (the blue) that the old was using, pressed the Power On button but....Nothing..... no "beep" sound no nothing..... all i could hear was the powersupply fan starting. then closing, then retrying, the stopping etc.

I put back the old card, all working perfectly like before..... I read that Raden HD6670 (PCIE 2.0) IS compatible with PCIe 1.6 (that my mainboard has).......

Am i doing something wrong? is there a possibility that my new GC card is faulty ? (bought it yesterday)

many thanks !

  1. do two things..check the power supply online and on the side of the power supply. does it have one 12v rails or two and what the max amp per rail. then check online the amp that both cards need. most times on older builds the 12v rail does not have the amps rating to run a higher end new card.

    see this model has more then one 12v rails there rated at 16a each.
  2. thank you, will check right now and report back
  3. smorizio:

    The GC card says that it needs 450W or greater power supply and 500W recommended.

    MyPowersupply is exactly the model in your link ZM-600HP. However I am not at all familiar with the amps and V...

    here's what my power supply says on the sticker in the side if it make sense to you

    12V output distribution list

    12V1-for CPU1
    12V2-for PCIE2/CPU2
    12V3-for M/B Accessory
    12V4-forPCIE1

    then underneath it theres a table that is as follows:
    __________________________________________________________________
    AC VOLTAGE | CURRENT | FREQUENCY |
    input--------------------- 190V AC - 240V AC | 10A-5A | 50-60 Hz |
    __________________________________________________________________
    DC | +5V | +3.3V | +12V1| +12V2 | +12V3 | +12V4 | -12V | +5VSB
    Max. Output | 24A | 24A | 16A | 16A | 16A | 16A | 0.5A | 2.5A|

    MAX Combined 155W | 504W | 6W | 12.5W|
    Wattage

    I tried to do it as good as i could...

    can you make something out from all this??

    many thanks!

    EDIT: It looks like my old GC was a Power Hog as it needed 2 power connectors

    needed in total 500W and was running with no problems since my powersupply could handle it easily....
  4. that the power to the cpu/mb 12v rail is 24v. which should be fine for that video card. what i would try is a 520/210 video card there made for the older dells and hp. you may have better luck or a nvidia 250. the older version is the 8800. they might not be as fast as you wanted them but they may work with your mb old chipset.
  5. I suppose you don't have another PC that you could try the graphics card in? Just to make sure it's not faulty,

    so you mean that my new CG cannot work with my configuration, no matter using any "tricks" or "tweaking", since its a matter of Power supply, right?

    oh such a pity......i was sure i could make this work somehow...

    anyway, thank you so much for your prompt and spot-on help.!

    Cheers,

    no unfortunately
  8. No it's not a matter of the power supply. You could probably run two HD 6670s. I would take the HD 6670 back to the store you bought it from and ask them to check if it's not faulty.

    will do, definitely!

    have a nice weekend!
  12. Just to bring closure to this post, I took the card to the shop, they checked it and was working without a problem. They kept it and gave me a full money refund....

    I guess i will stay with the old one until it kicks the bucket......or until i buy a new system....

    Thank you Smorizio and Sunius for all your help

    Cheers!
  13. I see. I hate when those things happens - it's not the most pleasurable experience. At least they gave you a refund!
