Graphics Card under stress = Lose my wireless internet connection

As the subject states, regardless of what game. I've noticed since upgrading my computer to:

I've noticed through MSI Afterburner (the graphs), that whenever my graphics card is using more then ~35% of its power I lose my internet connection. Is this likely my mother board at fault? Any help would be appreciated.

  1. Could be a PSU issue. When your graphic cards start to require more power it maybe begins to starve the motherboard and in your case the wireless adapter isn't getting enough juice. What make and model of PSU do you have?
  2. OCZ ZT Series 750W Fully-Modular 80PLUS Bronze

    Thanks for the quick reply!
  3. I don't think it is a lack of power then that is causing your problem as the PSU seems to be relatively solid with good reviews. A few people have mentioned on review sites that the modular cables sometimes work themselves loose especially to the motherboard but would be surely too much of a coincidence to happen at the same time as your GPU goes over 35% load. Hmmmm.

    I gather that to take it over 35% load you are gaming? If so are you gaming online at the time or is it at any time it reaches 35%?
  4. I've only noticed it so far while gaming, I could run a benchmark to test it while not gaming. As far as whether it only happens when I'm gaming online, that doesn't make a difference. Happens with offline games and online games.
  5. Yeah sorry just read that bit in the top of your post. My bad.

    What is your motherboard model as tried to search for MSI MS-7673 and it keeps giving me laptops!
  6. I am at a bit of a loss mate. Other than a driver update I don't know what to suggest. Found this on steam http://forums.steampowered.com/forums/showthread.php?t=1921108

    but dont know if it will help at all. Will have another think.
  7. I feel like my only recourse is to try swapping components out till it goes away. But that seems expensive :-( The first one I would try is my motherboard. I feel it is the most likely culprit.
  8. Is wireless onboard or a seperate card?
  9. Hummm, well if you feel like spending money is the only way I would just suggest just grab a wireless adapter, I highly recommend this one. Gets me 3-4 bars between 3 walls, a microwave, another pc, and a tv :) And a bit of space empty space in between.

    Edit: side note, I have no idea whats causing this oddity.
  10. Right sorry JC all this time I assumed that the wireless was onboard hence why you thought that it was the motherboard. From looking at the specs of your wireless card it could be a couple of things (you may have already tried these) :

    1. It has a operating temperature of upto 60c so could it be possible that the heat from your graphics card is pushing the wireless card over this temp and it is shutting down? Is your 570 a reference model or with a custom cooloer?

    2. Try different PCI slots and test to see if it happens but have a look at these reviews and see if anything is similar : http://www.newegg.com/Product/Product.aspx?Item=33-166-051&SortField=0&SummaryType=0&Pagesize=10&PurchaseMark=&SelectedRating=1&VideoOnlyMark=False&VendorMark=&IsFeedbackTab=true&Keywords=%28keywords%29&Page=1#scrollFullInfo

    I would personally point my finger at the card rather than your motherboard now but trying to explain the relation between GPU load and loss of connectivity is a head scratcher other than the operating temps.

    As you suggested earlier try and run something like 3D mark to push your GPU outside of a game and monitor its temps / load to see if / when it cuts off your connection. Come back and we will go from there.
  11. Did you reinstall windows when you upgraded your CPU? If not, that's probably the cause. Windows tend to tie themselves to hardware configuration, and if it is changed, some undefined behavior WILL happen.

    Gee, that is bizzare. Do you have any other PCIe devices? Have you tried a different slot? What is your power plan set to? Try setting it to 'High Performance', if it isn't set there already, and then make sure that 'Link State Power Management' under 'PCI Express' is toggled to off. There's only one 16x PCIe lane on the board, from what I can tell; maybe the card saturates the lane and the NIC starves? Weird!

    Could be EMI from the GPU scrambling WiFi since WiFi frequencies may correspond to harmonics of the GPU's core and DRAM operating frequencies depending on model.

    One way to test that would be to setup a grounded copper-clad board between the GPU and WiFi card and see if that helps. Tin/aluminum foil could also be used but would be more difficult to safely hold/secure in place to avoid shorts.

    Interesting theory, this seems plausible because I've found no problems when connected through ethernet. Before jury rigging anything, I'll try shuffling my wifi card and sound blaster card around and see if that helps.
  15. Tried shuffling around the cards, didnt work.

    All of a sudden it hit me! I turned on furmark, got my GPU to 99% usage and ran speedtest on my droid razr while holding it right next to my cards antenna. Guess what happened?


    Loss of nearly all wireless functionality.

    Clearly the card is interfering with the wireless signal somehow, any work arounds?

    I suppose i could get a card that has corded antenna to keep them away from the card?

    went with http://www.newegg.com/Product/Product.aspx?Item=N82E16812997086 we'll see if it works.
  16. I would try changing the channel that it uses.



    This is a handy guide to have around, maybe you can fiddle with the frequency and find on that isn't polluted by whatever is causing this?
