Gigabyte EP45-UD3R problem

[CosmicDust]

Can a video card be more sensitive than other on power !? Because i have 2 of the 3870x2 and...i tested with both. One of them had no problem when isntalling the latest driver from ATI and runs absolutely smooth on the PC , with that 400W PSU . The other one gives me a BSOD now with the same atikmpag.sys , when i try to install the drivers OR runs some basic tests. Once the "problematic" Graphic's Card , did work with 9.12 drivers , without a problem.

Any other thoughts!

Thanks guys !

Of course it is possible that the problematic card is just faulty or as you say draws just a little more power than the other card and there isn't enough from your PSU. I am afraid it is all conjecture unless you try a bigger PSU or something like that.

I just received an Corsair TX950W Power Supply and i will give more info as i do more tests. I also read in some forums that the BSOD might be the cause of UAC in Windows.
After testing i will post here.

Thanks

What was the Stop code on the BSOD ?

Here is a link with the actual BSOD !

Powered the TX950W PSU
I just got the RAM back,works perfect.
Now with the video card instead of getting the atikmpag.sys i now get an atikmDag.sys error ! The other video card, which is exactly the same works perfect. I think it might be the card, or one of the GPU's is not so OK .

Could i disable one of the GPU and see what's wrong ?

 error/BSOD code 00000000x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-GPU oroverclocking GPU)

Hello Aussie Allan and thank you for checking my problem !

Before i put the Corsair TX950 PSU the error i got was the one you saw in the picture attachment , after i put the PSU the error changed it;s name to atikmdag.sys. What do you suggest I should do? ....And could this still be a driver issue?

I found out the problem for the AMD Radeon 3870x2 card. Turns out that one capacitor that is located near the cable that powers the fan is missing ! Weeeird. I will add one and as soon as i solve this i will give you guys more info !

[Dark Mantis]

Be very careful, just because there is a place for a component(capacitor) on the board but it isn't there doesn't mean that it is missing. Often these boards are used for more than one model or they have been changed during production and now there is not meant to be a component in that space. I would check with the manufacturer before putting in a capacitor.

[CosmicDust]

The two boards are identical ! And is a clear mark that is missing . I have some pics but my phone ..has the resolution of a washing machine so they won't be that clear . I will try and post though see what you think aswell Dark Mantis.

Thanks

I am quite happy to give you my advice but as I say I have seen very many before that look as if something is missing from a circuit board but it isn't.  Please post what make and exact model it is too.

[CosmicDust]

This could explain the more power usage comparing to the other card ! There is also residual material there , some forme of glue. Since glue is used to stick two pieces together i think this was used to stick that small black material between the Capacitor and the PCB
Both cards were in a DELL XPS 730. Let me see if i can make some HQ pics with my iPhone ...i in this case stands for "idiot".

[Dark Mantis]

AS I said please post the exact make and model of the cards.

[CosmicDust]

The card is an ATI Radeon 3870x2 that was used in a dell XPS 730 PC. And to be more specific here is a photo.
