HELP!!! GTX 465 RUNS @ x4

Hey guys , 2 days before I got my gtx 465 , and now I have completed my rig ,
specs:
EVGA SR-2
Xeon E5603 1.6GHZ - OC to 2.5GHz
Corsair Dominaor GT 2000mhz 6GB ram
Galaxy GTX 465 vga
1200W Thermaltake PSU

btw: evrything is working properly except my gtx 465 running at x4 speed.
here is a screen shot

look it runs at v2.0 x16 @ x4 v2.0
and look at this:

in nvidia inspector it shows as x16, but in GPU - Z and CPU - Z it shows as x4
I have tried 285 , 310.24 drivers but it still doesn't change.
I have removed the vga and switched to all 7 pcie lanes but still the x4 speed.
temps are 42oC idle , 79oC load , ambient 27oC
I dont know why is this showing the speed like this.
and I have flashed the vbios to gtx 470 , but it still stuck at x4.
guys please help

 

its prob a power saving feature, try running something that will put a load on the card and check it while its running

edit - didnt see the render test running in the background

 

Ya, what can the problem be>?
and im running single processor, shall I remove this processor from CPU0 and install it in CPU1?
thanks

 

disable usb3 from bios

 

are you sure?

 

Hey!!
I disabled it but still same x4 speed, is there anything else that can fix this.

thanks for your help.

 

Do you have another card to test with?

 

I have a hd 6990 , but it doesnt have an cooler, so Im afraid to power it on without the cooler in it..
is there anyway, to check this without another vga?

thanks for the help.

 

Try a re-seat.

 

I did , but it didnt help.

 

Its a power saving feature. Put some load on the card and see if changes. Make sure the card is in the top slot

 

He has it under load in the SS.

 

in the right pcie slot? you sure that particular 465 can be flashed to a 470? the vram is 1024mb and the shaders are off too for a 470

 

yeah mate, op your particular GTX 465 is not flashable. your card does not have the same amount of memory chips as the 470. i recommend you re flash it back to the gtx 465 bios.

 

Yea its not a flashable version, but still even though I flashed it to gtx 465 vbios , the x4 stays.

 

Maybe that is a defective video card? Any pins on the connector bent or dirty?

Try removing all the other cards and just install the card giving the issue, see if it ramps up to 16x.

 

If its defective I should have got bsod , lines on screen , and all kind of things,
AND im running only this card in my evga sr2 setup. but still x4 speed.
thanks for help.

 

Clean the card's PCI-E connector with isopropyl alcohol and a Q-Tip/Microfiber cloth. Also, try dusting out the slot it's in.

 

If the right pins simply aren't making contact it may make it run at 4x, highly unlikely tho. Tried resetting cmos or putting the card in another motherboard?

 

need to know what slot is is. my board has a 16x mechanical slot but its limited to 4x electrically and is only for the PCH.
