hi guys,
a friend of me just bought an HD 3870 to an old system. according to ati ccc, gpu-z and rivatunre, the card only runs at 4x pci express.
he have a gigabyte 945gz, mobo p4 3.0 (631) processor and 512mg running at single channel.
he's getting very playable frame rates at cod4 at 1280*1024 with 4x aa but crysis and bioshock gets very low frame rates .. ( i think this is due to the memory limitations, right ?)
any way .. i didn't find anything in the bios about changing it to 16X neither did i find anything in the mobo catalouge or in the website refering to this mobo havin a 16X pci express in the 1st place (advertised only as pci express)
could it be that this mobo doesn't have 16 lanes for pci-e ?
will upgrading the mem to 2 gigz at dual channel put everything in it's right place ??
thank u guys in advance
