HI,
Prior to new install of new hard drive and a new retail version of windows xp pro I noted
all of my bios settings.After the install the only change I noted was in the advanced/video configuration
"PEG Negotiated Width" It was 32 prior to the upgrade and is now 16.
There appears to be no way to reset in the bios.The graphics card is the only component
to be affected as the frame rates are low now.Every thing else seems o.k.
I have the graphics card set right,as PCIE in the bios.

INTEL CORE 2 DUO E6700 2.66GHz 4m
4 GB PC6400 800MHz DDR2
MBO D975XBX2
GEFORCE 7950 GT 512MB PCI-EXPRESS
18X DVDRW DUAL LAYER
52x32x52/16x COMBO DRIVE
500 W PS
BARRACUDA 7200 500Gig/16mb

Any help appreciated, thanks

Per The manual for the intel Mobos.

This option is read only and provides the link train width
(x1, x4, x8, x16) of the PCIe device connected in the x16
PCIe slot.

This information is provided for determining performance
issues with x4, x8, and x16 PCIe cards if they are inserted
into the x16 PCI slot while the Intel Integrated video (PCIe
graphics) is enabled and the "PEG Allow > 1" option is
disabled.

32 according to intel should not be a valid option.

What Speed is your graphics card?

The clock Rate is 570Mhz,Memory clock is 1.45Ghz.Is that the speed info?
I am no one to dispute intel for sure,but I sure saw the number 32 in that
bios setting prior to the up grade,no matter it has to be something that changed
after the up grade.The FPS were really up there in FS9,now down a heap.
The graphic card is in the #1 x16 slot as recomended by Intel.
If and when I get it figured out I'll let you know, thank you.
