Is PCI-E x4 raid card compatible with an x1 slot??

Have not got a clue which forum this would go under but so ill ask here.

WINNER!!!

Haven't got a clue but I'll say yes it is comptaible.

It won't physically fit in the slot, unless it's a x4 or bigger mechanical slot.

See what you GD crowd are missing out on .

It's a more common question than you'd think, perhaps owing to PCI-x cards being downward compatible with PCI slots back in the day thus introducing the idea of expansion slot downward compatibility.

Hard Drives?? Did a GD mod move this?

If the card is 100% PCI Express spec compliant, it'll work with fewer lanes (provided you have a 'open ended' slot, or chop a bit off so that it does) - however some PCI Express cards are not 100% compliant - Rev 1 Intel PRO/1000 PT NICs, for example. The manufacturer should state the compatibility on their datasheet for the card, or ask them directly.

Actually 3.3v PCI-X cards will not work in a regular PCI slot that you'll find on a desktop board, but 5v PCI-X cards will. (so long as you make sure that the rest of the connector hanging off the edge doesn't connect with some other component - battery, say )

Yeah, the joke about PCI-E and that go on and on, but you'd be suprised how plug and play and chop and swap they are.

"In Theory" you put any PCI-E device into any PCI-E slot, and it will work.

"In Practice" it only works if the slot is bigger then the card. I recall toms hardware benchmarks where they stuck tape over the graphics cards to force them into x8, x4, x2 and x1 PCI-E mode and they kept working.

I also recall a picture of somone who took a hacksaw to a 6600gt and cut off the end of it up to the first notch... and everyone laughed and thought it funny how he had ruined a perfectly good card... but it probably would have worked, just at x8.

If I recall that photo correctly the gent in question cut a PCi-e 16x card so that it would fit into an AGP 8x slot. Needless to say I don't think it'd have worked.
