Nice rig, I bet not one of those units is really wasted at all. Bet they all get resent...No big deal.

Don't be discouraged, Jon.

Some of the comments earlier in this thread were, I think, a bit unwarranted.
Keep at it, ask for help where you need it, and some here will be more than willing to help you sort it.

I have had my share of trials and tribulations over the years with my overclocked rigs running into snags now and again.

I have not gone the Fermi route due to budgetary limitations, or I would try to help you out myself.

Nice build there!! Lucky dog, you. Hope you get 'er producing valid work soon...it should be a mighty rig indeed.

The Fermi's are able to do their work almost flawlessly, even when overclocked.

My Crunchy had its last error on the 19th :)

But with just one GTX470 I'll never get your RAC :P

I think Jon is taking some time off the board. The harshness from some here can be brutal. Nice going.

Hey guys, this is a friendly forum, isn't it?


Jon, WOW!, what a monster machine!
AFAIK, the first machine with 5x GTX480.

Thank you that you payed a lot of money and donated your free time for this machine.
And thank you that you will pay the electricity bill for this machine.
The machine will make a lot of science.
It would be nice if you could reach top_RAC_host_#1 with this machine.

AFAIK, on the new GTX4xx series GPU only the stock 6.10_cuda_fermi app run well.
IIRC, Todd Hebert made an easy file with all needed things (apps (CPU & GPU) and app_info.xml file) for GTX4xx series GPUs. Maybe you find the URL for DL in his message history. (But can't remember well if this was the stock 6.10 or a V12x build of the Lunatics crew)

AFAIK, you could let run 3 SETI@home CUDA WUs simultaneously on a GTX4xx. IIRC, you need WinVista or Win7 for this.
Then you would need to change the app_info.xml file, IIRC:
<coproc>
<type>CUDA</type>
<count>1</count>
</coproc>

to
<coproc>
<type>CUDA</type>
<count>0.33</count>
</coproc>


But then you would have 15 CUDA WUs simultaneously and I don't know if your CPU can manage this well.
You could test different settings. Maybe also a 0.5 value.
You need to look with help of GPU-Z how much the GPUs are used if they crunch CUDA. For example, my GTX260-216 have ~ 92 - 98 % usage if one WU, so no space for a 2nd WU.
Maybe MaGNeT (a.k.a. BlueTooth76) could tell you more about this. IIRC, he was the first who made this.

Maybe also the new BETA app of the Lunatics crew could run also on a GTX4xx. I don't know. If you don't have already an account there at the Lunatics forum, you need to contact Jason of Gecko that they give you a new account there, that you have access to the BETA forum there (IIRC, you need to post 5 messages in the forum for have access to the BETA forum).


Let us up-to-date and let us know if you need help!


EDIT: And please more photos of this machine! :-)

Hi Jon,

I see you've started getting some valid results on this box :-)
Which applciation are you using now? From the stderr it looks like you may be using one of Jasons builds?

Jon, it's look like you don't have a CPU app in your setiathome.berkeley.edu folder or a wrong name of it in your app_info.xml file:
http://setiathome.berkeley.edu/result.php?resultid=1669543250

You could take the Lunatics Installer V0.36 and install the opt. CPU app to a temporary folder. You could take then only the CPU app and copy it to your SETI@home project folder.
For your i7 920 I would take the SSSE3 app. Except you have fast or OCed system RAM, then maybe the SSE4.1 app is faster.
Then you need also the correct app name in your app_info.xml file.

If you like, post your app_info.xml file.

It should look like this (if only MultiBeam):
<app_info>
<app>
<name>setiathome_enhanced</name>
<user_friendly_name>SETI@home optimized</user_friendly_name>
</app>

I wish Jon would post some more photo's. I keep looking at the one photo and I cannot figure out what I'm looking at! I see 3 GPU's but the mother board is way below them on the table. That must be one big HSF assy on the cpu. It's massive if i'm seeing this right.

Come on Jon........more photo's.

it appears there are 2 GPUs plugged directly into the motherboard, and 3 more on a rack above, hooked to the motherboard via Ribbon extension cables. Definately a unique design.

Geek, two are plugged into the motherboard slots and then the three on top of those. One fantastic cruncher. Hope Jon is at least reading this thread so he can see all the helpful hints being thrown his way. That thing is going to fly when everything gets going good!! :-)

I have a bigger case but I am not sure it's big enough. The other problems are it still has a working P390 in it that can't be removed at this point in time and the fans are so loud that I had to put it in the garage. P390 are obsolete so if it would work and you can find a case, you should be able to pick it up for nothing.

5 cards with the i7 920 only draws about 1150w!

Is it possible for a 1150W PSU to handle five GTX 480's and i7 920??

Two psu's! A 1200w for the mb and 3 cards and a 1000w for the other 2 cards.
