I have not ran haven benchmark for 5 hours, but have run full benchmarks with no issues, as well as normal gameplay with no issues. The system does not become unstable until I start up BOINC client, as far as I can tell anyway


Suferbus,

I've seen a somewhat similar problem on two computers. On one, the graphics board fan was no longer turning, so the GPU quickly overheated after each reboot.

On the other, the GPU heatsink needed cleaning to prevent the GPU from overheating, but the graphics board cover could not be removed to allow this cleaning.

A program you might want to install to make it easier to see your CPU and GPU temperatures:

Hi Robert,

I tried to put together a comprehensive list of what is necessary to receive GPU workunits. You can either do step 1 and post back the results or take a look at your settings for steps 2-5 and see if anything needs to be changed.

- Happy crunching,
Steve

My previous reply to this message has disappeared. However, only item 4 below gave unexpected results.


4. Project preferences
http://www.gpugrid.net/prefs.php?subset=project
- Use NVIDIA GPU = on
- ACEMD short runs


I'm now getting both long and short 6.47 GPU workunits on this computer. However, all of them have the workunit repeatedly going unstable, and then failing with an unknown error message. In case it matters, this computer runs 64-bit Windows Vista.

Your message did tell me what to look for in order to enable CPU workunits but not GPU workunits on my other computer, though. The GPU heatsink on it needs cleaning, but is unreachable.

LAIM stands for "Leave application in memory"(while suspended) setting in boinc client under disk and memory usage tab.


It's on. However, I may have installed some updates and rebooted while the workunit was suspended.

Robert, was LAIM on?


What's LAIM? How do I tell if it's on?

Posted 13 days ago by Profile robertmiles
I'm thinking of upgrading my graphics cards, but first I need a piece of information I haven't been able to find online. How well do cards meant for PCIE3 slots work if placed in PCIE2 slots on the motherboard? Do they even fit in such slots, and so on? Going to a computer store and looking at the boxes such cards come in seems likely to provide that information, but is seldom practical for me.

My computer with this graphics board used to get only CUDA 4.2 workunits.

12/5/2014 9:12:47 AM | | CUDA: NVIDIA GPU 0: GeForce GTX 560 (driver version 344.75, CUDA version 6.5, compute capability 2.1, 1024MB, 852MB available, 1116 GFLOPS peak)
12/5/2014 9:12:47 AM | | OpenCL: NVIDIA GPU 0: GeForce GTX 560 (driver version 344.75, device version OpenCL 1.1 CUDA, 1024MB, 852MB available, 1116 GFLOPS peak)

After 4.2 workunits were discontinued, it got one 6.0 workunit, which failed, and it now gets no GPU workunits from GPUGRID at all, only the CPU test workunits. What do I need to change in order the get GPU workunits again?

This application appears to have problems restarting from a checkpoint -
I suspended it for a few days, then when I told it to resume, it gave a
computation error less than a second later.

Test application for CPU MD v9.01 (mtsse2)

I got one of the test applications for CPUMD.

http://www.gpugrid.net/result.php?resultid=13209824
http://www.gpugrid.net/workunit.php?wuid=10166393

Now at 0.442% progress (occasionally increasing by about 0.002%), 06:43:9 elapsed, 2930:20:57 estimated remaining.

Running high priority. Using 3 CPU cores, the maximum I allow BOINC to use on that computer.

If the estimated time to completion is anything close to accurate, I probably won't allow any more of these to run on that computer.

Running under 64-bit Windows Vista.

Something I'm having trouble finding: How well do the new cards using PCIE3 work if the motherboard has only PCIE2 sockets?

Time to replace my trusty GTX 460, which has been GPUGrid-ing for years! At ~£100 the GTX 750Ti fits my budget nicely but I need some guidance.

1. Is the power feed only from the mobo enough for 24/7 or should I go for one with a 6-pin connection?
2. One fan or two?
3. WHICH 750Ti do you recommend?

I installed a pair of 750Ti cards in my computer yesterday and tried to run GPUGRID. No go, instant fail within a couple seconds.

This quote is from January. I hope the problem has been fixed!


Something you didn't mention: If possible, get one that blows the hot air out of the case rather than blowing it around within the case. That should reduce the temperature for both the graphics board and the CPU, and therefore make both of them last longer.
