Just bought a new AXLE Geforce gtx 550 ti 3bg Video card for my AMD phenom 2 x4 @3.2.
windows 7 didn't seem to recognize or find the new card. however in device manager some new thing called a coprocessor has popped up. wiki says it is related. even after visiting AXLE3D.com to find a solution, which lead me back to Nvidia site for download of 500 series driver, the bloody thing still doesn't work. HELP have i been sold a dud!

More about : graphics card coprocessor device manager

have you connected the video card and all the power plugs (just one if i'm not mistaken).

if yes, is your screen connected to it?

If yes, it should be working, and recognizing the video card.

first thing i did was turn off pc, take old card out n put new one in. turned on pc no picture though win 7 did load up cause i could hear it. turned off pc, put old one back in. turned on and this time tried installing the drivers from the cd.
to cut things short, since then we've uninstalled the old nvidia drivers and other related software, restarted ( couldn't seem to get rid of ASUS smart doctor though ). then installed the latest driver ( 500 series ) from nvidia but that didn't work. then thought maybe it's a motherboard problem ( MSI AM3 mATX type - model nf725gm-p31) i've posted this issue at MSI support. see how this goes.

i think i may have discovered what could be the problem. my pci-e slot is only 1.0 and the card is 2.0. would this be the trouble ?

One thing to remember - always unplug the power cord from the psu - turning off the computer is not enough. There are still voltages present on the mobo unless you unplug it or use the switch on the psu(if equipped). A coworker of mine fried a mobo & ram before by not removing power.

they're backwards compatible

did you plug the pcie power connector to your card?

Actually I don't think they are backwards compatible...

Im using 2 7970s which are 3.0 on a 2.0 motherboard and it works beautifully. So dont listen to anyone who says it wont work like the guy above me.

the whole idea behind pcie is that they're backwards compatible from the get go...

PCIe 2.0 motherboard slots are fully backward compatible with PCIe v1.x cards. PCIe 2.0 cards are also generally backward compatible with PCIe 1.x motherboards, using the available bandwidth of PCI Express 1.1. Overall, graphic cards or motherboards designed for v2.0 will work with the other being v1.1 or v1.0a.


all you lose is bandwidth which has been proven many times to make very little difference, if any

No..... PCI 1.0 vs 2.0? PCI 1.0 much smaller. Also bottlenecks any modern discrete card.

you are mistaking 1.0 with 1x here...

there are 3 generations of PCIe (1.0,2.0,3.0; well there are also 1.1 and 2.1) and 2 slot types which are 1x (short one) for stuff like sound cards and 16x (long ones) for graphics cards which can then be split between cards in sli/crossfire depending on the platform, i.e. sandy bridge-e lga2011 has 40 lanes which gives you option to run 3-way sli in 16x/16x/8x mode whereas sandy bridge lga1155 has only 16 lanes which would translate into 3-way sli in 8x/4x/4x configuration

I think that statement proves my point... 'PCIe 2.0 cards are also generally backward compatible'

There's a reason they didn't use the word 'fully' as not all PCIe 2 cards will work in PCIe 1

I've seen a few people that have had problems like this using a PCIe 2 card in a PCIe 1 slot

you're grasping at straws here

the only reason they didn't use word fully is because you get only half the bandwidth of the generation ahead of it

PCI Express 2.1 supports a large proportion of the management, support, and troubleshooting systems planned for full implementation in PCI Express 3.0.However, the speed is the same as PCI Express 2.0. Unfortunately, it breaks backwards-compatibility between PCI Express 2.1 cards and some older motherboards


There's a chance he has a PCIe 2.1 card?

I meant much shorter bandwidth. x4 bottlenecks even mid ranged cards like 6850.
