Motherboard with most PCI slots?

Question

I am replacing an old motherboard with 6 PCI slots attached with 6 PCI fax cards.

Form factor is ATX.

Anybody know which brand/model I can purchase with that many slots?

Or is there an alternative?

PS: I prefer not to use more than 1 PC.

Answer 1

The ITOX LT600-DR is an ATX form factor motherboard, built around an Intel 945G chipset, with:

• Six PCI slots
• One PCI Express x16 slot
• LGA 775 CPU socket
• Four DDR2 slots
• Four SATA headers featuring onboard RAID
• Dual integrated gigabit NIC cards
• Integrated graphics
• Integrated audio
• PS/2 keyboard and mouse
• Four USB 2.0 ports

If my understanding of your requirements is good, then this motherboard should fit your bill nicely.

For reference, other ATX form factor motherboards from ITOX having 6 PCI slots include:

• G4S601-B-G
• G7S600-B-G
• LT600-D

Good luck with your fax server!

Answer 2

Supermicro does list a few. See their motherboard comparison chart and remember that PCI-X slots should are backward compatible with standard PCI.

For example the Supermicro PDSMA+ sold at Newegg has 5 PCI and 1 PCI-X so it should be what you are looking for.

Answer 3

It is uncommon (at least outside the server market) to find a motherboard with more than 2 PCI slots, and very rare to see one with more than 4, as most are the smaller mATX form rather than ATX and have space given over to PCI-E slots instead.

Before anyone can suggest alternatives you need to tell people (add the details to your question) what you are currently doing with the PCI slots - what hardware is in the current machine and what do you use it to achieve? Also what other features do you require?
