pcie slot running at x1? mobo issue?

[chopppy]

Hey,

im hoping the scan guys can help me out here. I have a gigbyte p35-ds3l, and last week i received a xfx 88800gs alpha dog edition which i bought elsehwere. i ran 3dm06, to onnly get a score of 4000 so i thought summat was wrong, i ran gpu-z which showed the pcie slot at x1 (how do i attach images?)

anyways i went and updated the mobo bios, load optimized defaults, still the same. then i started changing nb voltages, and changing pcie slot frequencies too and no change. im lost as to what to do now and what the problem is...i know its not a lack of power or anything, 450w with 26a on +12v. im guessing its the mobo cos its in charge of the pcie slot right?

i only bought this at xmas, so am still under warranty right?

iirc this is a known problem & there are usually 2 solutions
increasing nb voltage or increasing PCI-E frequency over the normal 100 (again iirc 105 usually solves it).

sounds like he already did that, send the board back if thats the case.

@ BUFF, i can only increase the NB using +0.1, +0.2 and +0.3, all of which ive tried. ive also tried every pcie frequency from 90 through to 110.

update, i risked running the card in my dell dimension 5150, well it worked on a 22a psu, which definitely rules out the psu in my rig. But the pcie x1 problem occurred in the dell too , and yes i updated bios n chipset drivers. guess that means its a gfx card fault?

Clean the contact fingers on the card, rub a pencil eraser across the contacts carefully without applying too much force, that should clear some grime and oxidation which may have prevented some pins from contacting the card.

If certain pins don't make contact with the slot, the PCI-E bus may run slightly slower, as seen in the link below removing fingers will reduce the cards bandwidth.

PCI-E x16 to x1 slot mod

If cleaning didn't work you should RMA the card.

okay guys, mystery solved!!

today i received my new hd3850, installed it and its working fine @ x16..so it was definitely the card that was faulty all along!!
