I have a HP Proliant DL360 G4. It has a PCI-X slot which I would like to insert a standard PCI card into it. From what I read, PCI-X is backwards compatible with PCI. When I insert the PCI card into the PCI-X slot, it fits fine but is over a half inch away from the bracket were you normally secure the card in place with a screw. 1. Can someone confirm the card is backwards compatible? 2. Is there another riser board, adapter or something I can use to secure the PCI card in place. Right now it is just sitting in the slot. (No, I haven't turned on the power until I get this resolved.)

It is possible that you may have the PCI-Express riser in your Dl380 which may be why your PCI card is not fitting properly.

Also, are you sure your card is PCI? What type of card is it?

The Mother Board has a PCI-X slot with a PCI-X riser board in the slot. The PCI card I am using is an Adaptec PCI ATA-2944UW SCSI 5V card. I just got off the phone with HP and have been told that the DL360 G4 PCI-X slot is only backwards compatible with 3.3V PCI cards. That was weird because all PCI cards I have ever used run at 5.0V. I have never heard of a 3.3V PCI until now. Of course you should never believe everything you hear so I started looking at PCI specs. The following site pretty much summed it up for me: Page 7 shows the several different types of PCI slots availiable (PCI-X being the 64 bit slot). Mine is the third slot to the right (3.3V 64-Bit). Well, today is a good day. I learned something new even though I didn't get the results I was looking for. Bottom line, the card isn't compatible.

Thanks for helping out. If you have anything to add feel free.

I copied the URL from the IE address and it doesn't seem to work. I went back to Google and copied the link before I clicked it. Here it is:



If you want I have an AHA3940 which will fit that server. Drop me an email or reply if you want to trade.

I believe the AHA2944 is a high voltage differential card. I've never seen an LVD card that is 5 volts so that still migth not help you.

What kind of device are you trying to connect?
