Dualview + Lan = Incompatible?

[Hajime]

Recently upgraded to a DFI Lanparty UT 250gb and all the trimmings.

Running a GeForce FX 5900XT (core OC'd to 5950U, mem to 5900).

Recently, I've been having no small amounts of trouble getting dualview and the LAN working.

If I have two monitors up, the onboard LAN can't properly handle DHCP - it won't find the DHCP server on my network.

However, if I disable two monitors, the onboard LAN works perfectly fine. No issues, nothing.

Ideas anyone? I'm stumped.

Weird. Makes me wonder if your PSU just isn't providing enough juice, assuming that dualview requires more of a power draw than a single display.

I've been using DualView + DHCP LAN since ... forever on a non-nForce mobo and have never experienced this phenomenon. Hell, it's also dual-Athlon and I only upgraded recently from 350W to 480W (had a gift certificate to burn).

Otherwise, your findings may just be a coincidence.

SU: Admittantly, I'm pushing it a bit with my current PSU.

350w Enermax, 'bout a year to a year and a half old.

Running a Raptor 74gb, 2x Raid1 Seagate 200gb SATA's, DVD-burner, DVD-rom, DFI UT NF3, Athlon 3200+ @ 2.33ghz, GF FX 5900XT (Core at 5950U, mem at 5900), and a few other parts (Ballistix, etc.).

But looking at the rails, I don't really see the problem. 3.3V is at 3.31-3.4, 5.0V is at a rock-solid 5.05V, and 12V is at 11.77V to 11.9V (Fairly steady 11.83V)

12V might be a bit low, but that might also be the DFI's measuring of voltage - it tends to err on the side of caution from what I've heard. Plus I don't see any of the other tell-tale indications of power issues.
