i think my brand new VIDEO CARD is broken

edrik said:

yeah.. what video cards would you suggest ?
i think my mobo could handle quadros if i'm not mistaken..


anyway this card was my first option but unfortunately they ran out of stock... here
so i went up and just bought two 1gb cards and added a sound system (Creative SBS A500) from the extra money..

I reckon a couple of these would be pretty good.

just installed 64bit RTM on my new rig and yeah it did boost system performance..
but my video card still ain't detected

Hi Edrik,

I have been reading this thread and I am puzzled about one thing.

If you are doing time critical projects on your machine, why on earth would you be running Windows7?

Even though it's RTM now, there will still be a bunch of compatibility issues to be solved.

However this doesn't have anything to do with your current problem.

I think Grim has made a solid point about the PSU.
If the thing has not enough amps on single rail, it is definitely the culprit.

About that shop that build the rig. I think they are morons, and they lack respect for their customer.

They should know the PSU can not handle the two cards on full throttle, and not send you home with a new driver installed.

Get a new PSU and a new hardware shop

Good luck,

Thinking about this again I am really concerned about the PSU your using because your cards are working solely from the PCIE slots with no extra power supply that would mean your entire system is operating on a single 12v rail and that single rail is only giving you 160 Watts/13 Amps.

A single card will need at least 100 Watts/8.3 Amps on Maximum load on it's own and you have 2 plus the rest of the system which is probably another 150-200 Watts or something like that so in reality you would need at least 400 Watts/33 Amps on the single Rail to be able to power the system.

Bottom line is Even though you have 1000 watts total you are only able to utilize 160 Watts because of your current setup and that just isn't enough, if you had the option of a 6 pin connector for each of your cards you would have no problems with your power supply because the main system components such as your CPU would have 160 Watts and each of the cards would be getting 160 Watts, in that configuration you would be using about 480 watts from your PSU, utilizing 3 of the 12v rails which would be adequate.

The only way your system will work, will be if you have at least 400 Watts on a single rail.

could i attach a 6pin connector for each of my cards ?
what are the risks ?

okay here's what happened...
after installing 64bit.. yeah my system really powered up.. but still 1 video card is detected.. so i turned off my computer.. removed the card and inserted it again..the system confirmed that i have two cards so i enabled SLI but after opening my software... my computer crashed.. it didnt respond to anything so i resetted my computer from the cpu reset button.. after booting up.. the other card wasn't detected again..

Edrik,

Please stop messing around with your system.

As long as the cards don't get sufficient power, it just won't work.

Mr Grim has written a very elaborate and accurate post on the matter.


One thing I noticed though, is that you mentioned the 6 pin connectors??

Do you have two 6pin sockets on your cards, and two 6pin connectors on your PSU?

I agree, if you keep messing with it in it's current state you will end up damaging the system, if you want to keep using it as it is I would recommend removing the second card until you can afford a better PSU, if the information you provided about your Video card is correct then you don't have any 6 pin power connectors and that's why you are having the problems.

To resolve your problem you will either need to change the PSU to a good 450Watt single 12v rail or the Graphics cards with something more suitable that will allow you to connect the 6 pin power supply from the PSU.

this is my PSU

if i were to buy new graphics cards which is most suitable for my current PSU ?
