AMD Uniprocessor MB with 64 Bit PCI

[trikster2]

Is there an AMB socket A motherboard that does not have dual CPUs that does have 64 Bit PCI slots?

Thanks!

I don't think so. I don't think any current single P4 board has 64bit slots.

You can get a Dual AMD board and use a single chip in it, and a 760MPX boards start at $200 so not that bad.

I have a 64bit/66Mhz ethernet card on my Dual Athlon Board.

That's a matter of chipsets. None of the commodity chipsets support 64-bit PCI, neither on Intel nor AMD side. For socket A, you need to have AMD's own 760MPX chipset - not found on any single processor boards. As Marlin said, buy a dual processor board and leave one socket empty. You don't have to buy an Athlon-MP processor then either.

I'm paying a $100 premium for 64 bit PCI if I get a dual CPU board.

Thinking of the free 64bit LVD 160 controller deal at hyper micro....

I think that card will work in a Reg. 32 slot, just will be running at 32bit not 64bit. Go to there site to make sure it is backwards compatiable, most are.

Oh, that LSI U160 adapter is 64-bit 33 MHz, but lives happily in a 32-bit slot as well. Besides, with one single SCSI HDD, you won't hit the bandwidth ceiling anyway.

Put in a gig ether card (like I intend to) and a several striped 15,000 RPM hard drives and you will easily hit the 32 bit PCI "bandwidth ceiling"

But dang I'm not sure I want to pay the Piper Peter (gosh I'm cheap!).

What's the point here? Do you really think the 2nd CPU socket and voltage regulation adds drastically to a high end board's cost?

Either go for the big gun and pay up for it, or be cheap and stick with the I/O performance you get from cheap commodity boards. GBit Ethernet requires 250 MB/s of its own btw.

I've given up on AMD but there are single CPU PIII motherboards with 64 bit PCI available:

$230 1.2Ghz server with 2 64 bit PCI slots

It uses a serverworks board I can't find anywhere:

I think my best bet is to just keep my eyes open for a gateway/dell refurb intel server and give up on finding a low end AMD server board.

It confuses me that everyone crazy silly about upping the CPU speeds to levels no one needs but basic things like I/O get ignorred....
