66MHz PCI and Core 2 Quad processor - motherboard support

[idata]

Hi;

I'm looking for a motherboard that supports:

Core 2 Quad Q9450 (755)

PCI Express video card

8GB DDR3 1333Mhz

But it also, will have a video capture card that requires a 66MHz pci slot and here is my problem.

I went to many different motherboards on Intel's web site and i can't find this feature (66MHz pci slot) on the specifications.

I'd like to know if someone can give me an opion/suggestion because i really want an intel motherboard on this workstation.

Thanks in advance.

Before we move on to your search for the

motherboard, let me guide you over PCI support in newer motherboards and how to

cope if a motherboard comes without a PCI slot.

The newer motherboards come with PCI-X

support and just one or two conventional PCI slots at max. Let us say that you

don't find a motherboard with a PCI slot and you have to, by all means, plug in

your PCI card in a PCI-X slot.

PCI-X is backward compatible with PCI 2.0

only, not with PCI 1.0 and 1.1 because the minimum clock speed for PCI-X is

66MHz. If your card complies with the PCI 2.0 specification (66MHz) it will fit

and work without problems in the PCI-X slot, but if you have a 1.0 or 1.1 card

(33MHz) it won't work. Moreover, originally the PCI bus was a 5-volt bus.

Later, in PCI Revision 2.x, the PCI bus was a dual-voltage interconnect. In 3.0

this was changed to 3.3 volts only. The PCI-X bus is not compatible with the

older 5-volt cards but newer 3.3-volt PCI cards will work in a PCI-X slot so always

ensure that the PCI card complies with PCI 2.0 specifications in order to make

it work with PCI-X slot.

Now, coming to your query about the

supported motherboards; your requirement was;

1-

Support for Quad

Core Q9450 Processor.

2-

PCI Express

Video Card

3-

8GB DDR3

1333MHz

• Also, you

  have a video capture card that requires a 66MHz PCI slot.

Now first of all as I have explained earlier

that even if your motherboard does not have a PCI slot, you can plug your PCI

card in a PCI-X slot provided your PCI card is PCI 2.0 complaint.

Moreover, here is a list of http://processormatch.intel.com/CompDB/SearchResult.aspx?ProcNbr=Q9450 Q9450 supported motherboards,

most of which fulfill your requirements; however out of all these, I would suggest that you go for either

• http://www.intel.com/products/desktop/motherboards/dx48bt2/dx48bt2-overview.htm DX48BT2

or

• http://www.intel.com/products/desktop/motherboards/dx38bt/dx38bt-overview.htm DX38BT

because they fully meet your requirements. You can plug in Q9450 processor, a

PCI express video card and 8GB DDR3 1333MHz memory along with your 66MHz video

capture card as you get 2 PCI conventional add in controllers. These are

extreme series motherboards and might be a bit expensive but believe you me,

they will give you superb performance with a C2Q processor and to top it all,

since the audio is Intel HD audio (7.1 dolby) and also note that 38BT supports

both ECC and Non-ECC memory modules.

I hope you find either of these motherboards

useful, let me know if you encounter any problems, keep me posted.
