XFX Radeon HD 4870 1GB

Hey,

I have some questions about my graphics card,
When i open my 'Catalyst Control Center' and go to the overdrive tab, it displays that the Current Values are:
GPU Clock: 600Mhz
Memory Clock: 900Mhz

But I have ATI Overdrive enabled, with:
GPU Clock: 750Mhz
Memory Clock: 900Mhz

Why doesn't the GPU Clock change?

If I click "Defauls" the program sets the overdrive to:
GPU Clock: 750Mhz
Memory Clock: 900Mhz

Could it be that my motherboard only supports till 600Mhz?

I tried changing the Memory Clock, but THAT does change.

I also have a question about the temperatures of my Graphics card,
when idle, its temperature is around 65°C
and when I am in game, it raises to around 90°C.

Isn't 90°C way to hot?
Will it reduce the life time of my Graphics card?
Should I replace the GPU Cooler?

  1. btw, my motherboard:
    MSI K9A2 Neo-f
  2. 90c at load is warm but not hot for a GPU, they can run hotter without any issue

    try rivatuner to change your memory clock speed or download the xfx tool. Your motherboard has nothing to do with it.
  3. I tried it, it changes for like 0,5sec and then changes back to 600Mhz
  4. If it goes above 95c, I'd get worried. Personally 80-85c is too hot for me.

    As for OC'ing the core, try another program. Have you tried OC'ing only ~20 mhz?

    I just changed the GPU clock using "Rivatuner", and that worked.

    Btw, what do you suggest i should do with my temperatures?
    I wasnt playing a really heavy game (Left 4 dead 2, 1280x1024).
    I am planning to buy a bigger monitor (24" 1920x1080), and play a higher resolution,
    wont my GPU get to hot, and raise to like 95-100c?
    At the moment i have Manual fan control disabled. (so, automatic fan control enabled)
  6. Either you need to take a look at airflow issues in your PC case (it may not be taking in enough cool air for the GPU cooler to work efficiently), or you need to alter the fan speed settings on your GPU.

    RivaTuner if I recall, will allow you to change the 'default' or automatic fan controls such that you can tell it to be at 50% at 50C, and 100% at 70C... or whatever works best for you. Could be as simple as upping the fan speed on the video card itself.
  7. I think my airflow is okay, I've got a Xigmatek Asgard Chase (http://i1.lelong.com.my/UserImages/Items/0910/29/bruceleestore@116.jpg)
    Front: 120mm sucking air in
    Back: 120mm blowing air out
    Side: 2x120mm blowing air in
  8. I'll try changing the fan configuration, and see if it helps : )

    Thanks for the help people :D
  9. Hello,

    I have exactly the same card, and the same temp issue.
    ( http://www.tomshardware.co.uk/forum/288459-15-hd4870-heat-noise-issue )

    I think I'll buy the Arctic Cooling fan replacement. I hope it'll be cooler and leeeesssss noisy.
  10. Hello,

    I put an Artic Cooling Fan on the card, and now the card is 30-40°C cooler :love:

    ( From 94°-105°c To 64°c :hello: )
