Re: What motherboards are based on Intel 915 and Intel 945 chipsets

Just because some people prefer, or even need to stick to products by
the dominant players in the PC business doesn't make them trolls.
Remember that no one ever got fired for going with IBM, Microsoft or
Intel.

Your apparent prejudices against the major industry players, probably
on account of their business practices are of no consequence to 99% of
computer users out there.

If you know of any non-Intel Pentium chipsets or AMD chipsets which are
known to work well with PV149 or Kodicom series DVR cards I'll be glad
to know.

PS. I'll be grateful if you don't take this thread off topic

Hi, I'd like to apologize for the rather uncouth and tangential
denizens of this NG.

Following your MFG's recommendation is definitely the smart way to go,
and I'd encourage you to ignore the blather you've heard. Although if
you want to try an AMD system, I'd ask the tech guys at Kodicom...

That being said, there's several things you should think about:

1. Is 1 PCI bus enough?

I suspect that if you are using 5 capture cards, you might want to try
and get something with multiple PCI busses. PCI does not give you much
bandwidth, only 133MB/s, which may not be enough for 5 cards to all
operate simultaneously.

2. Does your storage system have enough bandwidth?

You may get away with a couple of hard drives, if they are newer SATA
ones, but I have a hard time seeing a single HD being able to satisfy 5
video capture cards (unless you stick them on a single PCI bus, where
there's not that much bandwidth anyway).

3. How much memory do you need?

Video capture definitely uses up memory like there's no tomorrow.

4. How many processors do you need?

Gotta move that data around somehow...

It would really suck to find out that the wonderful system you've built
runs slowly because of any of those 4 issues.

That being said here's a list of motherboards (many of them from
Intel):

http://www.pcworld.com/reviews/article/0,aid,114620,00.asp

Two of the top ones have 5 PCI slots and work with Intel CPUs, some of
the other top ones have 5 PCI slots but are AMD boards. I would
strongly recommend both Intel and Nvidia's chipsets, they seem to be
pretty good.

The nforce4 chipset is relatively modern and supports up to 6 PCI
slots, so perhaps you can find a motherboard with 5 PCI slots that is
relatively new...
