Adaptec 31205

[nitrobass24]

I have this card and have been using it in an x8 slot because well its an x8 card.
I am thinking about getting a new mobo. But I would want to use it in the x4 slot.
Will this work?
I realize I am limiting my bandwidth.

I'm running a 3ware 9650SE-16ML on a Gigabyte EP45 S2 motherboard that has a 16x physical, 4x electrical PCIe port and it works fine.

I would imagine you would probably experience the same as well, unless there's some inherent issue with the Adaptec card or the motherboard with a card that has greater lanes than the bus itself.

Yea I am thinking that it *Should* work, but you never know I guess?

You still have your 16 port?

I still have my 16 porter.

It should work, if your physical slot is 16x or 4x open-ended.
PCIe cards are supposed to negotiate to lower lanes if necessary.
I heard some people melted the plastic away on close-ended 1x/4x slot to convert them...
Also, on some motherboards, you have to watch out for jutting heatsinks or other
mobo components that might get in the way. Assuming that's not a problem,
basically any PCIe card should work.

If you have too many PCIe cards though, you might run out of option rom - that is,
the card BIOS won't show up on boot, but it might still work fine after the OS loads.
