I've read in a number of places that people have had trouble with the
built in firewall on the nvidia chipset (nforce 4 ultra or sli) causing
data to be corrupted. If you download a large file then do an md5 check
on it - it fails. This is usually due to a bad download or corrupted
source file, but if active armor is not set up right on the chipset it
will introduce random byte size errors. This is the default setting
when nForce4 firewall is activated - defaults to a mode that will fail
in a nearly imperceptible way.
I downloaded some demo games and could not get them to be verified using
md5 though the file downloaded was the exact correct size. I switched
my cable to the Marvell lan port, downloaded and all would check out.
On comparing the bad downloaded files to those downloaded with the
Marvell Lan using dos utility "comp" (use comp /? to get command line
input required) about 10 bytes had different values in various places
throughout the bad file.
To fix the nVidia Lan port while running the built in firewall, in
nvidia's Network Access Manager setup program, the Active Armor must
have Internet Explorer or Firefox or whatever browser you use, plus
whatever download manager you use (if any) added to the active armor
programs that "offload". By offload I understand that the active armor
software is not processed by the cpu but offloaded to the nForce4
chipset which processes the stream coming into the lan port much faster.
I presume that the cpu can't keep up with the download and corrupts
the file. If you run the Network Access Manager in the web based
interface you will see the instructions of how to add programs in Active
Armor.
With that change the nVidia firewall with Active Armor on worked without
corrupting any downloads. I have a A8NSLI - Premium motherboard.
Just thought I'd pass that along...
