Problem with Sapphire 4870 1gb Please help!

I just bought and installed the 1gb Sapphire HD 4870 toxic OverClocked vapor-x edition card. Its supposed to have a 4000mhz memory clock but its only reporting as 1000mhz.

I bought the card at a computer fair today and the guy said it would say 1000 when i installed it but that all i had to do was go to the sapphire website and install the new catalyst drivers and it would overclock its self to 4000. Well, i did that and it still says 1000mhz. Can someone please help me? I dont know what to do.

Here is a link to the card i have. http://www.sapphiretech.com/us/products/products_overview.php?gpid=278&grp=3

please help me!

  1. The memory speed for the card is 1000MHz, however with the DDR5 quad data rate gives you an effective memory speed of 4000MHz. The guy at the computer fair was blowing smoke up your ass, trying to baffle you with ****. Nothing to do with overclocking with the Catalyst drivers at all. The nanny software on this site caused the slang term for bovine excrement to be represented by ****.

    so... pretty much i was ripped off? This is only a 1000mhz memory card? What i mean is i was going to get the HIS overclocked card with 4000mhz memory clock. (here is the link http://www.hisdigital.com/un/product2-414.shtml ) Does the HIS card have a real 4000mhz clock or is it really just 1000 like this one?
  3. rgsaunders is right! You did not get ripped off. You are getting exactly what you paid for! The effective rate of the memory on the card is 4000mhz. The HD 4870 has GDDR5 memory on it.
  4. They're all 1000Mhz, that's what they're supposed to be. GDDR5 is quad pumped, so the effective clockrate is 4000Mhz.

    You did not get ripped off, don't worry about it.

    Well thanks that makes me feel better but i still think if its really 1000 they should say that not something else...


    I forgot to list this in my question for the first post but when i plug the hdmi cable in from this card to my tv i dont get sound... just video. Can someone please help with this?
  6. 1000Mhz is very high.
    Most fast cards only have 850 Mhz.
    PCs for example only have 266 - 333 Mhz.
    Nothing is wrong.
  7. The speed is 1000Mhz, but it acts like 4000Mhz. Most memory is advertised at its effective rate, regardless. Look at DDR2 800, it actually runs at 400Mhz.
  8. ok, thanks for all of your help guys... can someone please help me with the sound problem im having with hdmi?
  9. dont give me any of your bovine excrement, LOL

    Just set your sound device to Digital Output Device (HDMI) instead of the Speakers output (the little speaker icon in the lower right of the screen).
    Your video card and monitor need to support HDMI sound. The cable on both ends also need to be HDMI since audio can't be sent through RGB or DVI cable.
    i.e. If its not very easy to do, then it's very difficult.
  11. if your 4870 has base clock of 4 ghz then its real clock would be 16000 mhz FTW !!!!!

    1000 mhz x 4 = 4000 mhz due to GDDR5 instead of GDDR1 hope it helps
