Re: Recommendation for a P-3 motherboard with ECC and AGP4x or 8x?

I'm looking at upgrading the motherboard in my computer, and I'm looking
for some suggestions. The "problem" is that this is an older system, and
so I'm having some trouble finding good recommendations that apply the the
right era of hardware.

The system, as it stands, looks like this:

Tyan T1837 Thunderbolt motherboard.
Pentium-III 1100MHz processor (in a socket-370-to-slot-1 adaptor)
1.5 GB of PC133 ECC memory
Matrox G550 video card
3Com ISA-bus modem

I'm completely satisfied with it, except for one thing: I just got an old
Apple Cinema Display with 1600x1024 resolution, and the G550 doesn't go
that high on the digital output. So I bought a Matrox P650, which
supports that -- but it's AGP 4x/8x, and the T1837 only supports AGP 2x.

Thus, I'm looking for a motherboard upgrade that will let me use all the
rest of my existing components, but will support the P650. In particular,
I want something that will properly support the ECC memory, rather than
just using it as if it's non-ECC.

Any recommendations? (Is there even such a thing as a motherboard that
supports a P3, ECC PC-133 memory, and AGP-8x?)

Thanks much!

Hi,

I have a few dual P3's still cooking here. Built a number of them back in
the day, using mainly Supermicro m/b's and occassionally IBM.

Offhand I can't think/remember a specific P3 m/b with ECC (most were "server
boards") and also AGP 4X+. I'm sure you already exhausted Google and thats
why you are asking here.

Didn't look at any pics or specs, but I take it that the Matrox P650 simply
doesn't support AGP 2X. It probably doesn't even physically fit in the slot
because it isn't keyed for AGP 2X? I had a similiar situation to that,
where not long ago, I wanted to "upgrade" the video card for one of my old
dual P3's. (Supermicro P6DBU, AGP 2X). Likewise, I wanted DVI out.
After googling and reading to figure out the "best" older video card that
would work with it, I picked up a Radeon 9700 Pro off of Ebay. The Radeon
9700 Pro is physically keyed to work from 1X to 8X. It was the last card
by AGP video card made by ATI to support AGP 1/2X. I've been happy with
it. It is doing all I wanted it to do and was dirt cheap. If you want to
spend a little more and have some a few other "gee-wiz" things to play with,
you could even look for a Radeon 9700 Pro All-In-Wonder.

Since all you are likely wanted to push out, video-wise, on the 'ol P3 is
2D, another idea is maybe get a new m/b not so much for video but for
dual-CPU. You can find a dual-P3 370 "server" m/b, with ECC support, SCSI,
etc for dirt cheap. Match the CPU carefully, find a cheap U2W/U3W SCSI HDD
just to put the OS on (can find them still unused for cheap these days), and
it'll make for a nice, rock-stable, 'ol machine. As for video, since it is
just mainly 2D, a cheap PCI card with DVI out is all you need. I have
something exactly like this running on an IBM L440GX+ (2x1Ghz) in this room.
It is running FreeBSD and is rock-solid stable.
