Are you using SP3?

Did you install the drivers that came with the card?

You mention the power connector so I assume you have connected it?

What motherboard are you using?

Are you using SP3? - yea

Did you install the drivers that came with the card? - yea but as i said in the original post the pc isnt recognising the card, so its not finding any new devices

You mention the power connector so I assume you have connected it? - yea, in the original post

What motherboard are you using? - asus p5gz-mx motherboard (in the original post :-s)

Your PCIe x1 slot doesn’t seem to be functional.
See 1-24 of your manual for jumper settings for the PCIe x 1 slot. Jumper must be placed on pins 1&2 for the slot to operate.

Did you install the motherboard chipset drivers?

From your motherboard specs:

1 x PCIe x16 @ x4 speed
1 x PCIe x1
2 x PCI 2.2

Link to downloads for your board.

Why are you posting under 2 names? And what USB 3.0 devices do you have that makes retro-fitting this old board worthwhile? Do you have a copy of the manual for your board? If not, use the link posted by OtheHill above, download the manual, then read the section on adding expansion cards & configuring the jumpers for the PCI-e slots.

The PCI-E x1 slot is disabled when you set XJ1-5 to pins 2-3

othehill - cheers for the suggestions ill look into it, when i looked through the motherboard manual i couldnt see anything about enabling/disabling the pci-e slot.

mickliq - i didnt realise i already had an account so signed up with mcmillan97 last night, this is my work laptop which obviously remembered the details, i hadnt even noticed until you had said (DOH!)

ive got a usb 3 external hard drive, when i saw the first card at £10 i thought it would be worth it as i wanted to backup my 1tb worth of stuff and just thoguht i would try usb 3 out

USB 3.0 is still in the growing pains stage. That said, the card should show up. Not sure if you will see it in Device manager or not. Have you tried connecting a USB 2.0 device to it?

Your external USB 3.0 drive will not show in My Computer if it has not been partitioned & formatted. Look for it in Disk Management instead. And check that jumper.

BTW, pretty crappy motherboard. The PCIe x16 will only run at 4x. What the H is that?

ive had the pc for 4 or 5 years now and the motherboard was crappy at that stage as well lol, just bought a house and getting married in 6 weeks so cant afford a new pc at the moment. :-(

ok, never thought of jumper settings (im pretty crappy at understanding them). ive got it working now but its disabled my pci-e graphics card now (simple one for watching films etc on my big tv) what do i need to set each jumper to so that both slots work (surely they CAN both work?)

cheers for all the help so far

Just look at section 1-24 of the manual. There are separate jumpers for the PCIe x16 and the x1 slots. The jumper needs to be set on pins 1&2 for the PCIe x1 slot. The other slot depends on the graphic card you have installed.

Link to the manual in #3 above. Just click on the link to get the manual if you don't have it.

dont think it can be done which sucks huge balls. it appears as though you can only have one or the other, i tried the 2 jumpers to the left to be on 1-2 and the right to be on 2-3, neither the usb card or my graphics card worked, switched them about, the same. god damn crappy motherboard!

cheers anyway folks

Most pci-e cards won't work at max performance of usb 3.0.
pci-e 1x is maxed @ 250 MB/s.
Most HDD never get that performance.
IMO a waste of money.
