Yes, most likely. The ATI GPU 5xxx series varies quite widely in performance and it also depends on how much CPU power is left to "feed" the GPU. It might turn out that your specific setup is simply not powerful enough to produce a significant speed-up when using the GPU.

Hi there, first time poster long time reader... :)
I noticed at first my GPU crunching was a little lacking in speed until I figured something out:
I noticed that when I run my rig (see stats below) at 100% CPU usage (crunching 4 tasks at a time) that my GPU crunches a task at about 3 basis-points a second e.g. 12.000%...12.003%...12.006%...etc.
When I have a CPU free (setting CPU usage below 100% but above 75%) then it can feed data faster to my GPU which crunches at 30 basis-points per second e.g. 12.000%...12.030%...12.060%...etc. This results in only using 80% of the CPU in total.
Or, leaving CPU usage at 100% and I have my GPU set to run 2 tasks at once then BOINC treats it the same as a CPU task and uses one of the CPU cores (crunching 3 CPU tasks and 2 GPU tasks). This also results in only using 80% of total CPU power.
Using only 80% CPU power is good for me as my rig is OC'd and this helps keep my CPU temps down to a manageable range.
Yes. It is :)
I have 5850+c2d e7600.
It's more better to run 1 gpu task+1 cpu task.
If i will run another cpu task, it's not enough cpu resources for ati :(.
Yes priority is higher in gpu task, but this dont work on ati :(
But work's on Cuda :)
And if i will run 2 gpu task ( 1gb video ), but pci-e 1.1(may be this is reason) , speed dramatically slow down :(
And about computation error on gpu.
I have such errors after standby/resume or hibernate.
On ATi and Nvidia :)
And now i simply dont use this :)
And exclude boinc work directiry from Kaspersky scan.
I have an intel i5 quadcore, 8GB ram, 64 bit windows 7 and the ATI Radeon HD 5570 card. One GPU works fine but I can't seem to get both Radeon GPUs running BOINC jobs. For example, with 2 processors reserved for BOINC I see 3 BOINC Einstein@home tasks running, 2 for the 2 dedicated processors and 0.5 CPU + 1 GPU.
Next, with 3 processors reserved for BOINC and I see 4 BOINC tasks: 3 on the 3 100% dedicated processors and again only one GPU running (plus 0.5 CPU). I'd like to see both GPUs running. I suspect my one GPU limitation is caused by my inability to upgrade the AMD Catalyst beyond version 11.5. I have downloaded and "successfully" installed the new version 12.4 Catalyst several times. But the version number seems stuck at v11.5 and when I check updates it recommends I upgrade to version 12.4. Anyone else stuck on only one GPU or have difficulty upgrading to Catalyst 12.4?
Yeah, my roommate and I have the same problem - after installing 12.4 it still indicates the last install version; 12.3 in my case, 12.1 for my roomie.
Looking online other people have been having the same problem, no solution yet.

i have the same "problem," only its not really a problem for me...i'm able to crunch the new BRP4 ATI tasks on my HD 6950 without issue. i've "successfully" updated to Catalyst 12.4, but my driver version still says 11.5. i'm wondering if the 12.4 Catalyst package is just a bunch of updated run times bundled with the old 11.5 driver files...hence why my driver info shows v11.5, even though the v12.4 download installed without issue for me, and the new E@H ATI GPU app works just fine for me...
Thanks for the great feedback! I am going to assume my non-updating Catalyst version number (11.5) will be fixed in an update. I just tried setting the GPU utilization factor from 1.0 to 0.5 in the hope of getting 2 simultaneous BRP tasks running on 2 GPUs. No luck, still just one GPU. I increased the number of CPUs from 2 to 3 and instead of another BRP task it took another Gamma Ray Pulsar task. Maybe I should constrain the jobs to be mostly binary radio pulsars.
I do have a 3-day backlog of Einstein@home jobs so maybe I have to work my way through them first before getting dual simultaneous GPUs working on my Radeon HD 5570.
Once new gpu downloads occur, the utilization factor changes.
this.
if you already had BRP4 ATI tasks in your queue when you changed the GPU utilization factor from 1 to 0.5, those tasks will continue to crunch 1 at a time. its the tasks that get downloaded after you change the GPU utilization factor that will run 2 at a time. remember, b/c the GPU utilization factor is done server-side now (instead of hosts-side via an app_info.xml file), it takes some time for the parameter change to take effect.

Is this enough video memory or not?
