trying to determine speed of pci-e 1x vs pci slot
So I have this old dell dimension computer I use for a server.
It's maxed out with 2gb of ram, clocked at 533mhz
It has onboard video with 8mb of shared video memory
and an onboard 10/100 ethernet port. It also has audio but i have it disabled in the bios.
I'm using this computer as a file and dhcp server for a local network.
It has 2 (and they're both empty) PCI slots and 1 (also empty) pcie 1x slot.
I wanted to get a gigabit card as I do a lot of transferring of very large files to and from the server.
when i called upon lshw to tell me if my pci slots were 32 or 64 bit i noticed that it is telling me that all the slots, even the pci-e are all 32bit 33mhz.
If this is true, then is my pci-e slot limited to 133 megabytes/sec instead of the 500 that i was expecting or am I misunderstanding how the bandwidth is calculated?
anyway, below is the output of lshw:
