Malogato said:I tried finding a PCI-e faq.. but here's a question I have about PCI-E
Are "greater" slots backwards compatible to "lesser" cards?
I've got an EVGA SLI NF4 motherboard.
It has, physically, from top to bottom
1 PCI-E x1
1 PCI-E x8
1 PCI-E x16
1 PCI-E x8
and
PCI legacy
PCI legacy
PCI legacy
Slots in it.
Lets say I pop my single PEG-16 card into the PEG-16 slot
and I want to buy 3 PCI-E x1 raid controllers [just a hypothetical]
Can I put two of them in the x8 slots? i.e.
can I have
Pci-e x1 raid card [in pci-e x1 slot]
pci-e x1 raid card or hell, network card, sound card [in pci-e x8 slot]
pci-e x16 video [in pci-e x16 slot]
pci-e x1 raid card or hell, network card, sound card [in pci-e x8 slot]
my pci video cap card in PCI slot
my old IDE raid card in pci slot
my old scsi card in PCI slot
Binkt said:Hey, I was wondering if there was anyone out there who has stuffed a PCI-E x8 RAID card (areca 1220, 3ware 9550, etc..) into the x16 Pci-express "for Graphics" 16 lane slot?
Is there any real difference in these slots, or am I good to go?!
LOL! "Lower bandwidth" should be taken with humor since PCIe 1x is still faster than AGP 8x (I think 8x or if not it's 4x)Lazn_Work said:PCIe 1x devices.
Eventually PCI (the bigger older usually white slots) will go the way of ISA. Just like PCI and ISA existed on MB's at the same time for a while, PCIe and PCI are both supported for now. But eventually no one will make PCI devices anymore and PCIe 1x is the replacement for lower bandwidth devices.

WTH? I must have been smoking something then. Still 250MB/sec is not bad for "Low Bandwidth"Lazn_Work said:PCI-E 1x = 250MB/sec
AGP 8x = 2.2GB/sec
AGP 4x = 1.1GB/sec
So nope.
