In November I bought a new PC with an Intel i7 6700k processor and a graphics card Asus Nvidia GTX 970, during the first weeks the graphics card could add between 300,000 and 400,000 credits, overcoming some days the 500,000 credits processing units GPUGRID and units processed in less than ten hours, then something happened and credit added per day was reduced, now the graphics card is adding about 200,000 credits 60% of the days and the remaining days manages to exceed 400,000, units take over twelve hours to complete and I have had units that took more than twenty hours.

Has anyone noticed in recent months a significant reduction in your credit added daily?
I think adding 200,000 credits per day is very little for a GTX 970.

Thank you.

Could have something to do with the GERARD_A2AR tasks. She thread below.

Your recent results are normal for a GTX970 running at stock speeds.

I disagree. My 970 typically gets over 500k per day with 750k days about once a week. My card is a factory overclock EVGA GeForce GTX 970 04G-P4-3975-KR but I doubt the factory overclock is making that much difference.



One thing that is critical is that the OP reserved a core to serve the GPU. Setting "On multiprocessor systesm, use at most" to 99% is a simple way to reserve a core for GPUGRID.

I wasn't saying his RAC shouldn't be over 500K I was talking about his recent returned results.

EDIT TO ADD

One reason he is not getting over 500K RAC is that despite completing units in lees than 11 hours he's taking over 24hrs to return thus NOT getting full 50% bonus which suggests BOINC is not running 24/7 or running 2 units at same time doesn't it.

Hi EMYArg,

from the scientist side, we are using the same algorithm to calculate the credit for each particular WU.

I hope you can troubleshoot the reason for this decrease.

Something to keep in mind is that my pc does not process 24/7, makes between 16 and 18 hours a day, for the moment I can not have the pc processing 24/7, something else to keep in mind and not if is related, it is that when my pc was processing making the amounts of initial credit did with the processor at high temperatures, then I installed software Asus reducing processor temperature and that seems to coincide with the decline in the credit added daily by units GPUGRID, I do not know if there is relationship between temperature reduction I7 processor and reduction in credit GPUGRID.

I appreciate all your answers.

... I installed software Asus reducing processor temperature and that seems to coincide with the decline in the credit added daily by units GPUGRID, I do not know if there is relationship between temperature reduction I7 processor and reduction in credit GPUGRID.

The CPU's temperature could be reduced by throttling the CPU, or reducing its clock frequency and voltage. Both have detrimental effect on the GPU's processing speed, as the CPU is feeding the GPU with work.

I looked at freedc and it looks like you are contributing to both GPUGrid and Poem@home. The asus tool is likely slowing your processor to reduce temperatures as Retvari said.

I would suggest removing the asus tool and reduce BOINC load to reduce temperature. Start with using 50% of the processors and see if that lowers the temperature enough. Adjust from there. My hunch is you will be better off running 5 work units at full speed rather than 9 (8 poem + 1 gpugrid) at reduced speed.

Many of us find the Cooler Master Hyper 212 EVO to be a good investment for the computers we use for BOINC. They are not expensive and are a much better cooler than the one that came with your processor. The other thing to consider is your 970 is generating a lot of heat you need to get out of the case. Putting a better heat sink on the processor will not fix a case that traps the heat from both the processor and the video card.

I wasn't saying his RAC shouldn't be over 500K I was talking about his recent returned results.

Yes, now I see what you were saying. The time his card takes to complete the work is right where it belongs.

Maybe he needs to configure his cc_config.xml to return work immediately.

$cat cc_config.xml
<cc_config>
  <options>
    <report_results_immediately>1</report_results_immediately>
  </options>
</cc_config>

I'm using my other pc to process units at the moment, until I can resolve the problems with my new pc, at this time BoincManager does not send or receive GPUGRID units, when the problem is resolved I'll keep processing, but with a Nvidia GTX 660.

Tanks.
