order this to replace a flaky no-name brand 256m 6200 . however , no matter what I try -lrb- and I spend several evening on this -rrb- I could not get this 512m evga card to work in a fic p4-486pe pro run xp - there be driver `` resource conflict '' and the card be leave stick in VGA mode . the resource conflict be in the memory map ; for some reason the video card 's 512m memory be always allocate in \* addition \* to the agp driver 's memory , and there just be not enough available memory for that in xp -lrb- and I have 3g of RAM ; it be more a issue of where the memory be allow to be allocate to device driver -rrb- . for my previous -lrb- and subsequent -rrb- 256m 6200 the card 's memory be allocate \* within \* the agp driver 's memory space and there be no conflict . this memory be separate from the `` agp aperture '' memory , by the way . I have the -lrb- one and only -rrb- bio for the FIC p4-486pe pro motherboard , the most recent Intel chipset driver and I try with various Nvidia driver - some older one , the one from the CD and the most recent 270.61 version . I also let the bio re-pick the resource and off course I perform all operation from safe mode with full driver uninstall and cleanup etc. prior to each attempt . I even try with a Ubuntu Linux setup and although I do get to a non-vga desktop it lock up right after that . so I can not tell if this be a issue with my bio or with the card - but for sure they do not play together and it just do not work . when I replace it with a new Gigabyte 256M 6200 everything work just fine . PS when you see a resource conflict with the `` vgasafe '' driver , whatever you do , \*\*\* do not \*\*\* disable that driver as that be the default VGA mode you get before you driver be install .
