Here's the situation. New server. 4 GB ECC Ram. Bios sees all 4 GB just fine. Windows 2000 server is reporting 3 GB. Called Intel, they say it's normal, that it's being used by motherboard resources. BS! Something wrong, just can't figure it. They say it's not hardware, but I think either slot 4 or slot 5 is bad. I switched out all the memory thinking maybe one stick was bad, but that wasn't the case. If I take out 2 GB, so there is only 2GB in the server, windows reports 2 GB. So if Intel were correct, I would think Windows would report 1 GB. Not sure what else to do. Any input would be greatly appreciated. Thanks.
