Hi,
I'm using asus m3a78 boards (with the sb700) for opensolaris and m2a*
boards (with the sb600) for linux some of them with 4*1GB and others
with 4*2Gb ECC memory. Ecc faults will be detected and reported. I
tested it with a small tungsten light. By moving the light source
slowly towards the memory banks you'll heat them up in a controlled
way and at a certain point bit flips will occur.
I am impressed! I don't know very many people interested in inducing
errors in their garage. This is an excellent way to demonstrate random
DRAM errors. Well done!
I recommend you to go for a m4a board since they support up to 16 GB.
I don't know if you can run opensolaris without a videocard after
installation I think you can disable the "halt on no video card" in
the bios. But Simon Breden had some trouble with it, see his
homeserver blog. But you can go for one of the three m4a boards with
a 780g onboard. Those will give you 2 pci-e x16 connectors. I don't
think the onboard nic is supported.
What is the specific model of the onboard nic chip?
We may be working on it right now.

I always put an intel (e1000) in, just to prevent any trouble. I
don't have any trouble with the sb700 in ahci mode. Hotplugging works
like a charm. Transfering a couple of GB's over esata takes
considerable less time than via usb.
I have a pata to dual cf adapter and two industrial 16gb cf cards as
mirrored root pool. It takes for ever to install nevada, at least 14
hours. I suspect the cf cards lack caches. But I don't update that
regularly, still on snv104. And have 2 mirrors and a hot spare. The
sixth port is an esata port I use to transfer large amounts of data.
This system consumes about 73 watts idle and 82 under load i/o load.
(5 disks , a separate nic ,8 gb ram and a be2400 all using just 73
watts!!!)
How much power does the tungsten light burn? :-)
