Had the same experience like you: my card errored out each & every WU on GG and when I switched to SETI it ran without any probs...
If you want to continue to crunch GPUGrid-WUs you have to lower your OCing until you get no more computation errors...

Sorry, but I think it won't work in your case: the Lian Li I've mentioned has the mobo installed upside down, so there's some space between the end of the mobo and the top of the case, enough for the part of the GTX that's overlapping...
The combo of 2 GTX295 + another single slot card should work...

You would need a case with 8 expansion slots to use three GTX295 together with an R II Ex, e.g. Lian Li V2010, Lian Li PC-P80 or an Lian Li V1000 Plus II (only 7 slots, but it will work)...

There are a some motherboards out now that can more than 2 full PCI-e slots. The ASUS P6T6 WS Revolution motherboard, for example, can run 3 boards in full x16 speed. Many will run 3 or more boards, but few will have them all at full x16. This board, and I believe there are a few others out there by other companies, could run 3 GTX295's at once at full speed, though I don't have the money to buy 3 of those right now.

Right at the moment I'm running 3 GTX295 combined with an ASUS Rampage II Extreme, 3 9800GX2 are used together with an ASUS P6T6 WS...and I've got an ASRock X58 SuperComputer capable of running 4 cards waiting for being tested with GTXs. So there are some boards out there now for a while waiting to be used for what they were designed for: heavy crunching... ;)

16 or 8x PCIe 2.0 is uncritical for now. It's a bit critical though to run 6 GPUs (3 cards) in one box.. concerning PSU, cooling and noise.

Both rigs are using 850W PSUs from Antec to feed the GPUs and i7-CPUs, both oc'ed...without any probs...and I got an 1250W Enermax PSU to be used if the four card configuration should work. All rigs are air-cooled...and about the noise: well, that's something one has to accept if he wants to run such highly performant rigs... ;)

As you mentioned: these rigs haven't done anything for the project this month...but the days I was dealing with the 'ghosts' were late monday and the whole tuesday...

And no: I didn't change anything...and these rigs will be back here as soon as they have cleaned their cache over at SETI...

When I saw that there were less than the usual eight tasks "in progress" I checked the previous task-sides, but with no success: I couldn't find any new ones. Also, after submitting these "ghosts" neither the 'avg. cr' nor the 'tot. cr' for this host did change...

Couldn't keep my promise to reach 50K just in time (yesterday)...
...and am wondering if anyone else had some "ghost WUs"...?

Explanation: during the last two days I had WUs, that could only be seen by the BOINC-manager, but not in the web sites task list. So I had eight WUs to crunch whilst in the task list there could only be seen five or six as "in progress". Could have been acceptable...if these WUs would have been listed after they had finished and were submitted...but they seem to have vanished in the Lost-WU-Nirvana...an unnecessary loss of time and credits...kind of annoying...

I was pleasantly surprised too...especially because the rig had freezes and produced computation errors...
My next estimate would be 50 K on next wednesday... ;)
