680i SLI is too expensive? Asus as the solution : P5N32-E SLI PLUS

Hi all,

I am running into a couple of problems with the mobo... Not sure if they are user error or not

1. The LAN ports were working for a while and are now not really working. I plug an RJ-45 plug from one of the ports into the router, and I can't successfully ping the router, nor see the Net. Initially, I could see the router and get to the Net. Then, Firefox would work and IE wouldn't. Now can't even ping the router. Anyone had problems with the LAN ports? I have tried enabling and disabling the unused ones, switching cables, etc.
EDIT: Found this article on the Web... Sounds like my problem is related to Zone Alarm: http://support.microsoft.com/kb/316414
** RESOLVED **

2. Not really mobo related, but I have 4GB of RAM installed. Viewing the System in Control panel would show 3GB previously - I know why this is, understand the 32-bit OS problem. I thought that I would get a little more, but was happy with 3GB seen in windows and 4GB in BIOS. Now, it reports 2.75GB. I haven't changed anything that I can recall. Any suggestions?

Thanks,

I have looked on this thread for an explanation on how the ratio between the fsb and DDR memory buses are set or how it works.
If someone could explain just how that works, much appreciated.
