Will this MXM card function?

First arrow points to 2 missing resistors. Second very small arrow points to 1 missing capacitor.
I believe they were broken off the board. They are all close to the HE tab which is normally only 2 pins instead of the several on this card.
Do you think the card will function at all?

Spoiler

 

Can't see a picture...

 

fixed.

2nd arrow is way too tiny (on my screen) I was doing it zoomed in.

 

Hard to tell ... sometimes there seem to be parts missing on the PCB, but in fact it's only an empty solder joint which may be used only for a similar version of the product... I hope you know what I mean.

But in this case I'd say chances are the parts got ripped of by force. Looking at the connector it doesn't seem as the card has been handled carefully at all.

 

Try changing the color or filling in the second (smaller) arrow, too, it's very difficult to find unless you already have an idea of where it is. As for the actual question... I have no idea.

 

I bought a 9500m gs on ebay, it didn't work. It looked like one resistor was ripped off the back. I soldered a random resistor in its place, card worked for a day or 2, then died.

 

I'm sure they were broken off. I have another identical card to compare it to.

I guess my question would be, do you think these components lead to single pins on the HE tab, and thus, are not necessary on a system that uses the HE tab all at once as 2 pins?
Anyway this is a somewhat useless thread as I can test it soon. I guess I'm hoping to learn something worthwhile about MXM structure if it is say partially working...

 

What card is it?

 

Its one of those 8800m GTS for the hdx dragon, with the red stuff

Thats interesting about the 9500m gs.
I wonder what the results would be with a higher powered card.

I'll see what it does like this and then try a few things. Maybe I'll just solder over some of the gaps. lol

 

If you have an identical card, get a multimeter and figure out what they are and replace them.

Funny, me and moral were just discussing how these cards look like they've been repaired and here I am thinking about repairing one.

Maybe I will be able to overclock more if I just bridge the resistors instead of replacing it. Anyone have any input as to whether that part of the board is actually leading to the HE tab? Or do you think its to one of the vRAM chips? that should have been my poll question lol.

I think my multimeter is broken isn't there a way to identify these kind of tiny components by color, at least to some extent?

Thanks all for the suggestions. Still, I have yet to test it, don't really have time until tonight.

 

The difference between having a resistor or no resistor at all can be dramatic.

Like going from 1.0v core voltage right up to the 12v rail.

Or its an important conection and wont work at all.

 

Yea, I realize that. I am going to try some sane options first.

 

Sane options? The only sane option is to replace the missing resistors with ones of equal value. Anything else is foolhardy and sure to leave you with a worthless lump.

Don't forget to measure the resistance of the two empty pads to make sure if you have to calculate the appropriate resistance.

 

The resistors are probably quite important but for the most part caps are only really used in noise filtration. You could probably live without the cap. Also, you wanted to know about identifying the parts, they're surface mount which means they have no colour code but if you look closely at them with a magnifying glass then they should have some info on them.

 

If there is anything printed on them, I doubt it is useful information. Also I forgot about them possibly being capacitors. If they are capacitors, they are just as required as resistors are. I've ruined handful of video cards by knocking tiny resistors or capacitors off.

 

I think monk was saying I could probably bridge the gap where the capacitor is missing?

Oh thats right, SMT is the term. I know they aren't color 'coded', but are caps and resistors generally certain colors by any chance? I really need a multimeter...

 

If you short a decoupling capacitor you will short circuit the card and bad things will happen.

 

No. Whether it is a resistor or capacitor, just bridging the gap is asking for a dead card.

There are codes for larger components, but not for those small surface mount parts.

 

Beside that what happened to that HE tab?

 

HAha yes the sandy bridge chipset recall is also because of smt resistors breaking off

I don't really know what happen to this card, I got it from cyberinfity and they had obviously only tested the other one I got.
I'll probably return it.
