PCI-E x16 running at x1 on new GTX 280

Abraxus# · 10-02-08, 05:57 AM

The title explains my problem really: gpu-z shows my pci slot is running at x1 when it should be x16.

I found this site (http://www.techarp.com/showarticle.aspx?artno=522) which describes my problem exactly but 'peg force x1' is off on my motherboard and i'm not overclocking so the nb vcore is set to auto (I tried setting it manually to lower than 1.45 but no luck).
I've changed drivers also with no success.
I can't use the other slot because the bloody massive card wont fit.

I have no idea what else to do. Please help

OPTION #1:
go into the bios -> set to default (load defualts) -> reboot
u might have to reset ur bios by either taking the batt out or shorting the clear rtc jumper

OPTION #2:
1. reset bios (look above)
2. put pci-e freq to 101, (if this doesnt work try 90)
3. put NB volts to 1.45 (or whatever is next to minimal

I tried setting the freq to 101 and the voltage 1.42 but it didn't work, also I put it to default in the bios , again, it didn't work.

I seem to be getting the VGA not detected beep codes a few times, then followed by the one beep (VGA detected) when it restarts sometimes. I checked that it was seated properly and it looks good, also all the pins on the bit that goes in the slot look good.

Could it be that it's a faulty card?

edit: I just put in my old card and it's working fine, I may send the 280 back.

Heh I have no idea... but is GTX 280 pcie 2.0?

I know people were having problems with the 4870X2 and had to change the jumper on the card to make it pcie 1.0

Have you actually tried running any games?

Agreed load the 280 up and see what it does before you rma it.

Maybe it's a reporting problem. What does the NVIDIA driver report? Click on Help in the driver control panel then system information. What information is being reported in the "Bus" field?

Reinstall your chipset drivers if you have not already.

i have this problem on my p5b deluxe, same chipset, cant set northbridge voltage higher than 1.45

I did try it out in crysis and clear sky, both of which had performance significantly worse than my 8800gts 320. I'm disinclined to think it's a motherboard problem as my 8800 is working fine right now. It stated 'pci-e 16x @ 1x' everywhere I looked (GPU-Z, nvidia panel).

I RMA'ed it last week, i'll post back when I get the new one.

Abraxus# · 10-08-08, 07:08 AM

Just got it back from the RMA today, they found no fault with it. I installed it just now and it works perfectly.

Sorry this isn't much help if your having the same problem, I googled it extensively and there seems to be no definitive solution, I just hope I stay lucky.
