Radeon HD4850 on PCI-E 2.0 x2

Hello, my ASUS EAH4850 reports, on the ATI CCC, that it's working on only PCI-E 2.0 x2, when I think it should normally report PCI-E 2.0x16.
My motherboard is ASUS P5B-SE:
Expansion Slots
1 x PCI-E x16
2 x PCI-E x1
3 x PCI 2.2
I'm running Vista Ultimate 32bit, and the video drivers are Catalyst 9.3, but it has shown the same thing with all the previous ones as well.
Another thing of note: Why does it report 1278Mb, and Hypermemory, instead of 512Mb and GDDR3? Is it good or bad that it uses system RAM? I'd rather not have it use any of my 2GB.

Thanks in advance.

Sorry if this topic is posted twice, my net timed out.

Bump for dear help. This issue is really bothering me as I think it holds my card back quite a lot.

Check through the MB manual, I do not think you have disabled the onboard graphics and set up the motherboard to correctly identify the card.

I actually ment Gpu-z lol... i dont know what i was thinking. but since you showed me the whole ''bunch'' i atleast know ur running ur latest bios,

to do list:

I would actually try enabling that force pci-e x1 function to see if it has an effect,

What psu are you running this and do you ahve your card connected with the aditional pci cable ( it should have a red light flashing on your 4850 if it aint)

Also actually try testing it on a bench or a game to see if its not fooling you lol.(wich i doubt oh well worth a shot)

and r all of your bios settings on default?.

also if you have the possibilty to test your card somewhere els you should ofcourse try that. Since if it does work properly on a diff machine we could b pretty sure its something to do with this mb.

So you should also test this mobo with a diff graphic card. Since tbh i think its a bios thing since you said you have the ability to force it to pci-x1 so why not 2 lol..

Gentlemen, I wish to thank you most kindly for your help.
After I reseated the card, and the BIOS battery as well, it seems my video card is running as it should, at x16.
This is solved.
