What is PCI frequency for a RAID card?

I've seen 33MHz and 66MHz PCI frequency for RAID cards and am wondering what that speed is for?

A regular PCI bus is capable of of moving 133MB/sec of data since it is a 32 bit bus running at 33MHz.

So a RAID card that has a PCI frequency of 33MHz is enough for anyone that isn't using a dual processor mobo?

Then 66MHz is double? and only useful for dual mobos?

Some device already need more bandwidth than regular PCI can offer so 66MHz bus should be benifit to single processor box too.

What you mean? But isn't the motherboard or chipset limiting the bandwidth? I mean for example a regular P4 motherboard can either handle 100/133MB/s which would be 33MHz vs a dual Xeon Motherboard which should be able to handle double that?..

66MHz cards are backwards compatable to 33MHz. 66MHz slots are used on server and workstation boards.

Yes and server boards are usually dual processing boards correct?

I'm trying to figure if I need a 66MHz RAID card or a 33MHz RAID card because that affects the prices.
and I'm using a Gigabyte GA-8IHXP mobo.

For that board and other PC boards, all slots operate at 33MHz, so there is no advantage to the 66MHz card.
