**Official DFI LanParty UT P35-T2R Review/Overclock/Guide Thread**

[mb.]

hello, since i have added an hd4870x2 to my system i am experiencing weird problems from which i dont know whats causing them. first off, i get that annyoing "the display driver has stopped working but was recovered..." in vista, but only with aero turned on. the bigger issue though is that i cant do 3d at all, either i get a bsod or the pc just reboots itself with a black screen. this only happens in vista home premium 64 sp1 though, in xp i didnt have a crash or whatsoever yet.
in vista i have tried four different driver sets for the x2 already and also tried with and without overclocked cpu. no success. now i am not sure what could be the reason. could it be the mainboard? i doubt that though since the user "C-N" stated that his x2 "works like a champ" on this board. but it seems he doesnt have a 64 bit os judging from his signature.
i was thinking maybe its the combination of p35 + vista64 + x2 (maybe + q6600)... but as i said i dont know thats why i am asking here.
ive already considered buying a new p45 mobo in hope that it will solve my problems but theres no guarentee and id rather not replace this board.
do you have any idea? thanks in advance...

my system:

q6600
dfi lp ut p35 (biso 521)
4 x 1gb teamgroup xtreem ddr2 800
