Hi peeps, i just got my first uad card this week,i bought it second hand from e-bay and iv'e run into a bit of a problem,i have just built the best daw i could afford,its a dual xeon with a asus NCHH-DL mobo with a matrox P650 graphics card, 1.5 gig of geil ddr400 ram,4 wd raptors set up as 2 raid 0,with xp sp1.After putting in my soundcard(st audio c-port) and all the latest drivers i installed the uad card,this is when the problem started, my graphics card stopped responding,my second screen shut down and the resolution reduced 800x600 and to 4 BIT.The error i get is that the graphics card doesn't have enough resorces and i should shut down another device.After reading a few posts on this forum i disabled the onboard Promise controller,this didn't work.I tried older drivers for both the matrox and the uad(of the original cd) After this i decided to re-install xp nice and fresh,all latest drivers,no pci cards at all,no usb and just 1 raid, i installed the matrox no probs,then as soon as i installed the uad the grapics went again, i tried the uad in another slot same again.Hopefully someone can help as i have totally run out of ideas, i also tried sp2 aswell no better.Cheers for your time, ian j.
