The following was updated in release P26:
- Wireless PCI card fixes
- Removed LinkBoost support (Please see below)
“LinkBoost was removed from nForce 680i SLI because it
did not show significant demonstrable benefit in games.
We had hoped newer games would take advantage of this
additional bandwidth but this has not been the case.
Please note that future BIOS upgrades will only remove
the automatic overclocking component of LinkBoost.
Users can still manually overclock the PCI-Express and
HyperTransport buses in the BIOS.”
