Does anyone know of a motherboard with 6+ PCI or PCI-X (not pci-e) slots or a combo of both? I would think that it would have to be an extended atx (e-atx) board.

6 PCI-X will be hard being a shared bus, that means two full controllers at least and I think at 3 slots per controller only 66mhz each.

What kind of cards are you running?

telecom. SEE DBA , I bet his AMD could be adjusted to hold 6 PCI-X slots.

It's all in the risers (and number of bus). Very do-able.

I suspect old telecom gear like Analog taps/PRI taps digium etc

Why PCI-X?

Thoughts are slower and also older higher power consumption cards
Some cards just didn't come out in express versions, or are expensive somewhat custom creations that cost 10s of thousands so if they are working fine no sane reason to replace.

PCI can be superior to express by a few metrics, the one common reason is latency in some use cases.

A dual or more bus pci-x controller board is not as common though, you'll find a lot of mixed pci-x + pci-e if its newer, or pci-x + vanilla pci if its older.

Take a look at those special-purpose PICMG single-board computers and their crazy backplanes.

Here is one with 14 PCI-X slots for $99: 19 Slot PICMG Backplane 5 ISA 14 PCI x 64bit 33MHz 16 5" x 12" Trenton Computer | eBay

Here is one with 18 PCI slots for $10: http://www.ebay.com/itm/PORTWELL-PICMG-18-Slot-PCI-Slots-2-x-ISA-Slot-Backplane-Board-PX-20S3-VER-E3-/251379106366?pt=US_Server_Boards&hash=item3a875cc23e

Another one with mixed PCI and PCI-X slots: PCE-5B18-88A1E-18-Slot PICMG1.3 Backplane; 1PICex16, 8PCI-X, 8PCI, RoHS

Of course you'll need to buy a PICMG CPU board as well. These are generally either extremely slow and cheap or just a little slow and overpriced, but if you need PCI, they are the way to go.

This is for Pika dsp telecom cards. They are PCI cards but PCI-X is backwards compatible.

Yes a backplane setup will be the last ditch due to the cost of having an extra chassis ect im not quite sure a single board computer will be enough. I will check out PICMG looks like they have some good options.

I have no idea why anyone would run PCI-X cards in a monster HP DL585 G7 server, but you can... with an optional board... but only two cards maximum. That's $5,000 per PCI-X slot.

Go all of the way back to a DL580 G4 and you get four PCI-x slots, though you have to put up with CPUs that probably wouldn't run an alarm clock.

I think you could use these Rioworks Rhapsody HDAMA. They list it as being shipped only in EU, but you could either ask them to ship overseas, or look for the board elsewhere...

Gives an appreciation for why that class of boards exists. Thanks thread.

Once again DBA you are the master of machines.... I went with a custom build from advantech.com. Many thanks!

The Supermicro H8DAE has 4 PCI-X ports, you can probably find one already with CPU and RAM for a reasonable cost.

Edit: I found this H8DA8 already with CPU and RAM and 4 PCI-X ports:

Considering the OP and previously oldest post was from 9 years ago, it’s safe to assume they are no longer in the market for a pci based board.

Yes, I didn't check the date, but for some reason the thread appeared in "trending".

I was looking for a board with a PCI-X port for a friend and stumbled upon this thread.

My friend just bought a giant Heilderberg printing machine that requires a PCI-X controller board...
