Hi, I read your edit. I suspected a change in workunit structure at first too, but I can conclude that BOINC is the real cause of the issue. The same workunit I was working on before and which I paused, crunches 4x as fast with BOINC 6.4.7. on the GPU.
(edit)
I can also notice by the GPU temperature, it shot up by 10 degrees after going back to BOINC 6.4.7. It is much more efficient.

The 6.4.x series needs manual tuning to get it to properly feed all GPUs, 6.5.0 does not need this manual tuning.

See the other threads for my comments on 6.6.20, .23 and .24

I just noticed that I have queued up a work unit that looks very different than prior work units. I guess this work unit is one of the new ones just released today. Of note is that the estimated run time is double that of the older tasks.

I suspect what you're seeing is also one of the new ones, and perhaps they're just bigger.


As it turns out, that new work unit is now running, and despite having an initial estimate that was much higher, it seems to be running in the same time as the older work units.

GPU temperature is normal, and, oddly enough, CPU usage for this task is back down to 15%.

Hi!

I use 32 bit OS and crunch gpugrid :)

Do you have also 64 bit version of your aplication?

I mean real 64 bit, no 32bit runing on 64 bit os.

If you have 64 bit is it faster then 32?

I don't know if it is time to upgrade to 64 bit os.

My comp have 4 gb ram, on XP 32 bit I have 3400Mb witch is ok ...

Since there is little time spent on the CPU, changing the application to 64-bit won't make much difference.

Projects where that can help include Prime Grid, ABC and at least one other and my mind whet blank. Oh MW with the optimized applications.
