Not trying to be rude,But have you even read the manual?

GPU goes in the dark blue slot.
install the 12.2 drivers.
It might also help if you give us your complete system spec's.

ter updateing to the 895.5 drivers form the 895.0 3dmark wouldnt run but with the 895.0 it cannot detetc the GPU

seems like there is a major problem with the 7800` driver i suggest to not buy any 7800`s atm until they relese new ones

... which wil probably alos be ***

The drivers for these cards appear to be sketchy, wait for the next ones to come out and hopefully fix the problem you are having

The OP needs to re-seat the card. it is not being detected at all. You need to ensure that it is pressed into the slot properly which by the sounds of things it is not.

Does anyone even read the problem these days? Nothing to do with drivers. the drivers won't install because NO CARD IS DETECTED. Meaning not physically inserted properly.

the card is detected when i install the drivers but it is not detected bye windows 7 and windows doesnt auto grabs the driver for it and install it. i installed the 12.4 peview drivers and yay the only thing that it fixed was it can now run 3dmark the low fps and performance is still there i hope by 12.5 they are fixed....


if not im gonna have to buy another card cause i didnt pay 400 for the performance basically and in some instances lower than a 6870

Ok,By chance,have you tried the drivers on the disc that came with the card?

found this on another forum:

"I cleaned the contacts in the video card slot with a rubber eraser

After that I tried the video card in there & the System detected the video "

@ methixor, you’re confusing people with multiple threads.

Your problem lies with your video drivers and ccc

DO NOT use driver sweeper.. as it removes .Net Framework 2.0

Without ccc your gpu is useless.

Reinstall your drivers with the original driver cd your gpu came with. It should reinstall .Net Framework 2.0 and related components.

Do not driver sweep before updating drivers thereafter, just use ccc to update.

k i did that removed everything put driver son cd on drivers of the cd is just catalyst 12.2 anyways then i update to latest ones what btw hwo muc power is it suposed to use on a 99% load of the gpu?


if i use the power control in catallyst and put it up bye 20 it increased the frames like 10fps from 30 to 40 in some benchmarking programs

furmark is fine for benchmarking fps performance.

I'f youre still getting bad fps i would check the net to make sure your psu is capable.

heres a copy paste from the link i gave you
----------
Here is Guru3D's power supply recommendation:

Radeon HD 7850 - On your average system the card requires you to have a 500 Watt power supply unit and 650 Watt if you go with two cards in Crossfire mode.
Radeon HD 7870 - On your average system the cards require you to have a 550 Watt power supply unit as minimum and 700 Watt if you go with two cards in Crossfire mode.
If you are going to overclock the GPU or processor, then we do recommend you purchase something with some more stamina.

There are many good PSUs out there, please do have a look at our many PSU reviews as we have loads of recommended PSUs for you to check out in there. What would happen if your PSU can't cope with the load:

bad 3D performance
crashing games
spontaneous reset or imminent shutdown of the PC
freezing during gameplay
PSU overload can cause it to break down
----------

This is worst case scenario, since moving on from a 6870 minimum 500watt to 7870 minimum 550w

This is all i can do, sorry.

yes certainly sir, more than enough.

Roll back to older drivers and test. don’t use driver sweeper.

Its either driver or a dodgy card. I hope for you is the former.

i got 3dmark here is my results

http://3dmark.com/3dmv/3984138;jsessionid=7otw35tu3cy01ebsyikwgtd1v

and 3d mark 11


http://3dmark.com/3dm11/3045784
my score here doesnt match the 7520 score they got in the reviw but there clock was at 1175mhz mine is at 1100mhz

the scores match up to the ones in review but as u can see at the top it doesnt recognize the graphics driver or card in the tests

both are run in P mode like in the reviw link u put there

your results say you have a "Generic VGA" that usually means the drivers aren't installed. If anything that last thing I would try is clean install windows and then getting the latest drivers or even the latest beta drivers

it only says generic vga in the benchmarks prolly cause they do not support my new card in windows and everything card is detected fine and in other pgorams it recognizes the card in 3dmark and 3 vantage in the pgorams picks it up as a 7800 only when go to post results online does it say that
