Hi!

I just mounted my LP UT P45-T2RS and for last few hours I'm trying to solve "little" problem - with GTX 260 PCI-Express x16 works only in x8 or sometimes even x4 mode. No matter what NB Voltage, what drivers (or even without drivers), what settings or what BIOS (1007 or 1028) I use - everytime GPU-Z and CPU-Z reports "x8" mode. When I switch card to HD 4870 there is no problem, PCI-E run with full bandwidth - back to GTX 260 and again, PCI-E only in "x8" mode (on a different mobos like P45-UD3P or DK P45-T2RS Plus it was working fine)
