Hi,

I have a problem that i think i know the answer to, but i want to be sure..
I have two Graphic cards (HD3870 and GF8500GT).. And after loading windows the Computer restarts.. I think its the PSU that is the problem.. I can use one card at the time, but not both at the same time (HD3870 for Graphics and GF8500GT for PhysX :D )..

I have a ACE RAW 520W (A really cheap and crappy psu).
So, should i change the PSU, i was thinking about CORSAIR TX 650W because i think it's good.. ;) 

So, could the PSU be the problem?

It could be.

Most obviously is your ATI and NVIDIA drivers wont ever play nice together, and that is probably your problem.

Im not a GPU guru so someone correct me if I'm wrong, but I dont think one should use Nvidia, and Ati together.

The PSU could be the problem, but it's hard to know for sure. The TX650 is a great choice, and it definitely leaves room for future upgrades.

As for using the 3870 for graphics and the 8500 for PhysX, I think it is possible on XP. It's a definite no go on Vista though :( . Although I don't know how much using an 8500GT for PhysX will benefit you...

Change the PSU anyway. It may not be the problem, but it may save your whole computer later and you can rule it out as the cause.

Get the PC Power & Cooling S75QB 750W, it's only $96.00 till 9/26 if you use the promo code PCPC20 shown on the top of the page in red.

I use WinXP 64-Bit, so it "SHOULD" work (I think) with a Ati and Nv card.. I've seen people do that with XP (lucky bastards)..
It could altso be the Driver problem because, i could start my computer when the cards didn't have the drivers installed. But, when they have their drivers installed do they drain more power then?

I agree, your drivers are fighting for control. hell, some people refuse to mix nvidia chipsets with ati cards and vice-versa. Prolly not a good idea to mix the two video cards. Although its a unique setup, it prolly won't be worth the headaches.
Kinda cool if you could get it to work I guess. If you really want a dedicated physics there's easier ways to do that.

Hmm.. But i think i will buy a new PSU, for the future ;) 
And i should probably ask some guys at NGOHQ, they maybe know anything about this.. I will tell you guys later if i get it to work.. :) 

But one thing, i have both cards in my PC now, but i have deactivated the 8500 through the Device manager (In Safe-Mode) so i have the drivers left on my computer and it works "perfect" now.. Oh well, see how it will be in the future.. ;)

Well you cannot run multiple display drivers at the same time in Vista.

  • If multiple graphics adapters are present in a system, all of them must use the same WDDM driver. If there are two graphics adapters with WDDM drivers from two different manufacturers, then Windows will disable one of them. The VGA adapter will be enabled, and the second device will be disabled.

    This limitation is not present in XP.

    Hmmm

    Sounds like an interesting experiment!!

    +100 for that PCP&C PSU!! Your current one could cause you problems... if not now and some point in the future. :sol:

    +1, that's an awesome deal.

    Yeah, that is a awesome price, but i live in sweden and I don't want to import and use credit-cards.. Damn, that deal is super cheap (compared to swedish prices) and I don't know if PCP&C even exists in sweden.. If so, then it will be probably expensive.. :o

    The TX650 is a good PSU, I don't know what your specs are but it will probably cover you.
    September 22, 2008 5:35:02 PM

    For now i've got an:

    C2D E6320
    2GB Kingston 667
    HD 3870 PCS (Powercolor)
    ACE RAW 520W
    ASUS P5K
    500GB Samsung..

    So yeah, i think it would cover my system pretty good. ^^
    September 22, 2008 7:40:59 PM

    Yeah, absolutely no problem.
    September 22, 2008 8:01:39 PM

    Hehe.. ^^
