AMD Radeon HD 6670 and MoBo Pegatron M2N78-LA

My MoBo only has a PCI Express 1.0 16x Can a HD 6770, which needs a PCI Express 2.1 16x, will not work with my MoBo?

CPU: AMD Athlon 7550 Dual Core

  1. it will work fine but it will bottleneck u r cpu note any pcie x16 slot run any gpu which have capable with x16 slot
  2. Can you explain what bottleneck is? Will it lower my FPS?
  3. nottleneck means that ue cpu is not much powerful to compete with gpu to run confidently that means u r gpu is the most powerful in u r system hence it will give smooth performance and yes it will lower the fps but nothing to worried about because most ot the games are basically designed for more gpu since ur cpu use it by 30% and 70% of gpu

    How are you so sure, you know a working combination of this mobo and card ?

    There are cases a 2.1 card doesn't work with 1.0.

    I do know what a bottleneck is but after your explanation i'm totally puzzled. :pt1cable:

    Anyway ; 100% sure it will work with the 2.1 mobo ? Please answer, this is important for swogtach.

    @swogtach ; spoiler doesn't work.

    I'm not sure but I think you have to click the spoiler.

    Btw, thanks for both of you for helping.
  7. "I'm QUITE sure it MAYBE will work" . . . :lol: :lol: Thats being confident there for you ! I'm quite sure off something else . . . :whistle: Maybe better be quiet . . . :lol:
  8. And where is this info, from that link, where you find that the mobo will work with a 2.1 card ?
  9. Oh, yes, yes, yes, euh, oh, no, no, no ; never get your answers from yahoo ; they are :pt1cable: . It's even offending placing a link to that on Tom's, there should be a Tom's rule against that actually !
  10. Not sure who the stupid arrogant . . . is you're talking about, but maybe good to say it's not allowed to be disrespectful to forum members. Not by name calling anyway.

    Those clips were from 550ti's ; they are 2.0 cards NOT 2.1 Sigh :pfff: :pfff: :pfff:

    GET YOUR ACT TOGETHER MAN ; so far i've seen no evidence at all !!!!
  11. And i DO wanna help, making sure it WILL work for 100%, not because i think i might be sure, maybe, i guess.

    I give up.

    Against so much thickheaded stupidity nothing will prevail . . . :cry:


    @Swogtach ;

    Unfortunately there are some cases where a 2.1 card doesn't work with a 1.0 mobo. Not much cases but still. Sometimes a bios update fixes the problem.

    The ONLY way to be absolute certain is to search the net and see if anyone else with the same mobo has that gpu running with it, not a 550ti 2.0 or a bladibladibla 7.38, but exactly the same card.

    Otherwise it's just a gamble. Not a great gamble but still, thats the one you must make yourself.

    It's possible someone here reading this has experience with that mobo, who knows.
  14. It WOULD be nice though if some other FORUM MEMBERS gave their opinion on this matter, it's only a two man viewing point now. Not easy maybe for Swogtach to see who's right ( or less wrong :heink: )
  15. Oh, and by exactly the same card i mean a 6670 card, not the same brand or model. ( though it has to be a 2.1 card,there are also 2.0 6670's )
  16. Okay. Thanks!
    Another question; I only have a 300W power supply. Is this okay?

    BTW! I meant 6670, not 6770. Sorry.

    It should run on it, unless it's a crappy one.

    Could you maybe open your case and look on the psu how much amperes there are on the +12V rail ? Or if you know the brand/model thats maybe enough to.
  18. I will search the net also, don't have much time at this moment but see what i can do. :)
  19. Uhhmmm. I have the stock power supply which I cant seem to find any information on. I'll keep on looking.
    Do you know where I can find the information you're looking for on the power supply?
  20. As of right now, I cannot check it. Do you recommend other Graphics Cards that can run TF2 at equivalent or decent FPS while the settings are on high?
  21. Pfff, don't know that game but i doubt you will get high settings, maybe medium, i duuno. Also depends on res. Your cpu is also a bit slow i think, didn't look at that yet actually.

    A better card than the 6670 is a 7750, uses even less power. But it's 3.0, or it should be called 3.1 because . . . you guessed ; same compatibility problems in some cases again.

    TF2 is a mod based on Half Life. These are the requirements


    CPU: 3.4 GHz Processor
    RAM: 1024 MB
    Graphics Card: Radeon X800 or Geforce 6800
    Windows 2000/XP/ME/98
    Mouse
    Keyboard
    Internet Connection
    CD or DVD rom dr
  23. Final answer to whether 2.1 cards are compatible with 1.0 boards. I suggest you read all of it:

  24. Didn't find a definite answer yet, still looking. Did find this though with a 6790, could be a compatibility problem. Not for sure though. http://www.bleepingcomputer.com/forums/topic431083.html

    Nuff said. :D
  26. This one suggest you could run a 6670. Yeah :bounce: The guy has problems but they seem to be psu related.

    Maybe you can ask the guy how it all worked out ? You probably need to register for that and i don't wanna, you can do that easily yourself.

    Only thing is ; it's not quite the same, other processor, though MAYBE same mobo and with that i come to the next point ; i did read that there are a lot of different version of your mobo, all kind of purple-ish colors or something, all with different specs . . . Meh.

    Maybe better to buy a new psu and a Nvidia card though you'll have to look for more expensive cards then because Nvidia doesn't do well in the lower price range.

    Maybe a gtx550ti/gtx560 with a new psu or just take the gamble with the 7750.

    I keep looking though.
  27. Okay, thanks for all the help!

    No problem.

    What pc do you have btw, specific model ? Makes searching a bit easier because of all the different versions.
  29. I have an HP Pavilion p6115y
  30. Ok, figured out that you have the violet version and that there are also violet 3 and viola and others . . . ( somebody liked Jimmy i guess ; Purple Haze ! )

    Didn't find any answers though.

    Afraid i have to give up.

    Let us know what you're gonna do and what the result is.

    Good luck.
