I have two HD 6950 2GB, one with a higher score and one with a lower score, when comes to crossfire mode, the score didn't increase much, why is that?

Here is the 3Dmark score of my 1st card.

Here is the 3Dmark score of my 2nd card.

Here is my 3Dmark score with crossfire mode.

As you can see the performance aren't really good, is it because the second card is broken so it throttling my first card?

the reason being that some (Only a small amount, most cards work fine) cards in crossfire barely effect the score, the best way to see if the upgrade makes a difference is when you game.

Yes but other than Crossfire, why does the second card have such low score when its the same card as the first one?

it may be recorded in the results, but the score isn't added entirely up for an unknown reason, this is the case for very few crossfire setups.

I know but I actually took both card out and put each one in, testing it one by one, therefore it has nothing to do with Crossfire, its the card and I can't figure out what is wrong.

What happens with each card?

Like the scores, One card has like 1000 more scores than the other one, thats a big gap and I looked at other people with the same setup, they get high scores like 6000.

scores vary depending on your system also. You card does seem it is faulty, that is if it is running in the X16 slot.

Yes I use both cards in Pcie X16, Do you have any idea what might be causing the faulty?

I don;t have an ideas, the fault could be anything.

Do you know which component can be the main problem? such as cooling, GPU etc?

trying to pinpoint is almost impossible, it is almost impossible to fix it as well.

Well do you know any applications that allows me to test for error and performance of GPU so I can see if my card its really having problem.

Load GPUz and check the clock speeds of both cards. Have you tried some other driver versions also?

I have never tried other version of the drivers but in the use of GPUz I founded out that the first card's clock speed spikes up and down, often goes to 800MHz then drop back to 250MHz; on the other hand the result of my second card which is the one with the lower score, has a constant 250MHz clock speed, I wonder this have anything to do with it. I will provide some picture from GPUz.

Hey,
have you bought the second card second hand? Maybe someone has spent the last 2 years bit coin farming 24/7 and has fried it?

The other thing I can think of - in crossfire cards tend to heat up a bit more than usual. Have you monitored their temperatures while under load? Maybe the second card is overheating and is throttling its speeds down. Try http://www.cpuid.com/softwares/hwmonitor.html or similar to see what are the temps like.

No I brought it brand new, it came in the same time as my first card.

I see,

have you tried using the "slow" card in the PCIe slot of the fast one?

When gaming/benching both cards should hold at 800/1250 not fluxuate
Is overdrive set to default? Can you verify CPU speeds and temps?

Are those pictures while playing? If so, that is awfully strange to see nearly no GPU load

It does go up to 1250 when gaming and overdrive is enable and default. You can see the pictures I uploaded to this thread while playing BF4
