My GTX690 died the same way. Later I've found the two 12V pins on the 24-pinned MB power connector was burnt. These 2 pins power the 4 PCIe slots and the memory and the chipset. The latter two are negligible when there are 4 high-end GPUs installed. The total power consumption of 4 high-end cards from the PCIe slots could be 4*75W at worst case. There is only that two pins on the 24-pin power connector which have to supply that much power. That is 300W+ combined, or 25A@12V. 25A on two pins is simply too much, so it is quite advisable to choose a MB which has extra PCIe power connector(s) to power 4 high-end GPUs in the long term.
I suggest you to check the 24-pin power connector on your motherboard & PSU for burn marks on the 12V (yellow cable) pins. If the PSU is a modular one then check both ends of that cable.

(Is the 980 on x16 lane and >1450Mhz?)

My GTX980s are on PCIe3.0 x8 lanes, GPU clock is 1420MHz.
At the moment my hosts are on vacation, because we have daytime outside temperatures around 37°C (99°F), and now I have 29.5°C (85°F) in my room (no AC).

I average 19 hours each for 2 WU (long one) on my GTX970 with a dedicated cpu core for each, did someone know if this seem ok performance?

GERARD_FXCXCL12_LIG_1035426
GPU load 84%
Overcloked to 1440mhz Stable. +150mhz on memory.
Windows 7 64bits
Fx-8350 4ghz
Asus m5a97 r2.0
8gig ram

19 hours is a bit too long for this GPU, it should be around 12 hours (even on a WDDM OS like Windows 7).

Also Running Rosetta@home on 6 core.

Rosetta@home has the most demanding CPU app regarding CPU and memory usage (bandwidth & working set size), so this could be the reason for the GPU tasks taking this long to finish on your host. If the rosetta@home project usually grants less credits for the finished tasks than your host claims, it is a sign of that host is overcommitted. See your host vs my laptop (recently my laptop runs only CPU tasks). As GPU tasks are more rewarding, I usually prioritize these (i.e. I reduce the CPU tasks running until the GPU tasks don't suffer the lack of bandwidth). 8 CPU cores need a lot of RAM bandwidth, so this CPU's dual channel memory controller could be a serious bottleneck while using all cores for running many instances of the same demanding application (like rosetta@home's). If you have only one RAM module in this host, I suggest you to put in a same one to achieve dual channel memory (as it will really double the RAM's bandwidth).

The GPU temperature looks fine.
Try to reduce the GPU clock by 50-100 MHz, if it doesn't help then try to reduce the GPU's memory clock by 100-200 MHz.
GERARDs push the GPU a bit harder than NOELIAs.
Even the successful GERARD workunits are full of "simulation became unstable" messages on this host.
It could be a power supply problem also, check all power connectors for burn marks.

Your answer on your question is here:
2015. 07. 02. 9:36:50 | | Disk: 20.00 GB total, 3.58 GB free
2015. 07. 02. 9:36:50 | | max disk usage: 5.78GB

And here:
2015. 07. 02. 9:37:00 | GPUGRID | Message from server: Long runs (8-12 hours on fastest card) needs 1113.40MB more disk space. You currently have 3654.98 MB available and it needs 4768.37 MB.

You have limited the disk space, which can be use by all BOINC projects together to 5.78GB, and it seems that 2.126 GB are already used by various BOINC projects. Your problem now is that the new Long WUs demand 4.468 GB, but as you have restricted disc use to 5.78 GB and used already 2.126 GB, BOINC asks for 1113.40MB more disk space, so it can download the WU.

You have two ways to go:
Your either delete not used file in your directory "C:\Documents and Settings\All Users.WINDOWS.0\Application Data\BOINC" or you change your settings in Computer Preference under Memory and Disk Usage the maximum allowed disk space, as well as the percentage of disk space your allow BOINC to use of your Hard Disk. However I do see that your Hard Disk is quite small, and therefore this might not be possible.

You're wrong. I forgot to say that I've solved this problem before I've posted about it by deleting unnecessary files from various locations, but I've left the BOINC directory as it were before. So the root of the problem is not the size of the BOINC directory and its size limit, but the total free disk space. The long WUs didn't demand that much free disk space before, and these workunits never use that much (4.468GB) disk space. The problematic "very long" workunits had the longest result files (about 187MB). The GPUGrid folder inside the BOINC\projects folder is about 300MB, the two slots of the GPUGrid app is about 44MB each, so the whole GPUGrid project is using less than 400MB disk space on my hosts. It is quite unnecessary to ask for 10 times more disk space than that. I didn't changed my disk usage preferences for a long time, also there was about 3.5GB free disk space on this host for a long time, so this change came from the project's server.

Well, if you're calling it a bug, I suggest you do some digging into - for example - BOINC's startup reports about what disk space exists on your computer, and what your preferences allow it to use. Post the opening lines from the Event Log here for others to analyse, if you're not familiar with doing that yourself.

Calling it a bug was the conclusion of my analysis of the event log.

For what it's worth, long run tasks are processing normally here, so it isn't a project-wide problem - it's something specific to individual machines.

Yep, but I have 7 active hosts, and it seems to spread across them. I'm using only 3 of them for other purposes, but it does not interfere with the partition BOINC resides, as I used to boot to Windows 7 when I'm playing.

I've received this error message on my other two hosts.
Nothing has changed on these hosts by me, and the free disk space haven't been decreased on them lately that much (by 1300MB, as the log says).
This is a pretty annoying bug, because my spare GPU projects still can crunch on the GPUs.

I've noticed one such workunit on one of my hosts.
It takes 11200 seconds (3 hours and 7 minutes) (~44%) more than a GERARD_FXCXCL12_LIG to process, while it gaves 4125 less credits.
It has a very low GPU (GTX 980) usage (~86%) even on my WinXPx64 host.
