Connectors on these boards are 16 and 18 pins. 16 pin has eight 12v and ground, 18 pin has 7 of each. I'll take a picture of my PSU later if it might be of any use.

Indeed :)
But the pinout migth be the same for 8th gnd pin, pson, atxpgd and 5vsb =)
8x512mb ddr2, how should i go about filling the slots? populate cpu0[0-3]+cpu1[0-3] or something else?
I have all eight of mine in the middle dimms.
OMG PERFECT CASE FOUND!!! The case in this ebay listing is absolutely perfect, anyone has an idea of that it is???

I'm just booting up my Arimas after a summer hiatus. I can't get either one to post. I suspect the power connections as a couple of those adapters had leads that were pushing through. I made sure all had good contact but no luck. I was able to get them both to "power up" with just LED 3 and 4 lit. But not POST though. I am having the worse luck with computers lately.
Anyone think of anything I am missing? http://img59.imageshack.us/img59/766/imag3878.jpg
How long are you leaving it on before shutting it back down? It takes probably 15+ seconds to POST mine.
I left it on all morning while I was at work.
Now I can't get any response out of one. I'll try the other one in a bit.
These are seriously the most finicky boards that have ever lived. When we bought these and I was testing each and every one I was getting the weirdest behavior I've ever seen. I sent the weird acting ones back to the seller but it wouldn't surprise me if our boards start acting like this. Mine wont connect to the internet. Sometimes it wont boot. Sometimes it takes a long time to boot. It wont accept the original video card I had in it anymore so I had to install a different one. Bottom line..start reseating /changing things out until you get it to boot. It takes patience.
Edit: Oh, and then never turn it off again :)
Mine has been running 24/7 with almost zero restarts. I came home a few weeks ago to a fried electronic smell and now it will not post.
Hmm so far so good on mine. It just chugs along :para:
Ya, if I ever get them to boot, then I won't shut it down until I replace it with something. This sucks.
I'll try different RAM, since I have some of that laying around. Thanks guys.
I got a Dell N1000P-00 power supply modded to 3x 8-pin EPS and can't get any post or any sign on the computer. The power supply works perfectly with my Tyan S4985. I'm using an Opteron 8222 and four 2GB DDR2 ECC Reg. I have all four CPUs and a bunch of memory sticks, but for initial start I read something about using just one CPU in the socket CPU0 and four DIMMs that go with that CPU. Any suggestions??? Thanks
Can you take a pic of how you have everything setup, especially the power. You need more than just 3 eps (need a six-pin in there too) to get it to boot. Also, I don't think installing all the cpus and ram will hurt or hinder anything so go ahead and get them in there.
All four DIMMS in the slots near CPU0? Not spread out amongst all of the banks.
My two Arimas are the same. Won't post after sitting for a long time. I'll try again next week in hopes for SC week.
The one plug needs 2 EPS connectors, the second plug needs 1 EPS and either a 6 pin PCIe put in backwards or (what I did) a second EPS with the leftmost wires clipped.
All 4 sticks go in the CPU0 slots.
These boards are also extremely picky on video cards. I tried a couple before I found one that worked. Seems that generally speaking these boards don't like nVidia cards, and only some ATI cards work. I have a PCIe X600 in mine.
It also takes a good 10-20 seconds for these things to even POST.

First off, thank you for the replies! Above are some pics I took of my PSU connectors and my motherboard. My PSU used to have a 20-pin connector that I cut off and solder to two 8-pin connectors. The picutures will say it all. I don't get any power to the motherboard. ...btw, the PSU is in working order because I'm using it on a tyan s4985. Any clues? Thank you!
Did you jumper the green wire from the original 24pin plug to a black (ground) wire to switch the PSU on?
Thank you for the quick reply! I don't know what you mean by jumping the green wire; I don't use the 24-pin connector at all.
Ok, I'm looking at the 24-pin connector and I see the green wire; what do I do with it?
wow!!! thank you!!! I did work! I thought I had a bad motherboard!!! You saved my life!
:) not a problem. See, the Arima doesn't have a typical power connector, so it doesn't trigger the PSU to turn on like a standard PC does.
Dang you Sparky I wanted to fix that!!! lol nice work man! Glad she's up and running for you prof.
Prof what case do you have this installed in? I'm pretty sure none of could find a suitable case..
Heh, sorry, I'm just online wayyy too much to let you do that :D
What? I have a perfect "case" :ROTF:
