1) Message boards : Number crunching : Frequency (in Hz) that should try to complete individual work chunks.- say what? (Message 60057)

"Frequency (in Hz) that should try to complete individual work chunks. Higher numbers may run slower but will provide a more responsive system. Lower may be faster but more laggy. default 60 (corresponds to 60 fps [frames per second?])"

Can anyone clue me in on this setting? I've tried "Googling" it for awhile and couldn't find any explanation for it or when (if ever) the default setting should be changed. Here's some info on my PC and prefs, in case any of them make a difference in using the default setting or not

2) Message boards : Number crunching : "ATI-GPU not found" problem solved! (Message 59864)

BOINC: 7.0.64 (64-bit)
CPU: AMD Quad-core FX-4300
HD: 2 TB
OS: W7 Ultimate 64-bit
Video Card: Radeon HD 6570 - using Catalyst Control Center (CCC) 13.4

Awhile back my ATI-GPU went MIA according to BOINC: "ATI GPU not found" which was vaguely disturbing since it had been used previously by Einstein@Hm and MilkyWay@Hm.

After reading a bunch (ie oodles, to be more precise) of message bd postings here & elsewhere (BOINC, MilkyWay@Hm, etc) I made sure my drivers were up to date both according to AMD and W7. (BTW I'm using "CCC 13.4" but AMD is up to 13.10 Beta, which seems to be mainly updated to improve the performance of several games; I've learned the hard way to never use BETA anything) After making sure my AMD drivers were up-to-date BOINC still couldn't find any GPU - or a cc_config file either. I couldn't find any (expletive deleted) cc_config file either even using an "Ultra-Search" utility and another program called "Recuva" which will even look for deleted and written over files. AND I couldn't find anything about just making up another cc_config file - even with my hyper-advanced [sic] search engine skills, so instead I just changed my BOINC and project preferences to not use a GPU.

Problem solved!

Well not really for someone who is anal retentive and who is always trying to learn how to solve PC problems, esp since most of mine originate with me in the first place trying to "tweak" my PC and "improve" it's performance instead of leaving it at W7's default settings (ie Lowest Common Denominator settings) So, next I tried "repairing" BOINC via W7 add/remove programs (there's a "repair" option along with the "uninstall" command) but the GPU was still MIA. Then I noticed BOINC was installed in my "Program Files" folder (the default installation setting which is actually wrong for a 64-bit program) so for the hell of it I uninstalled BOINC and re-installed it in "Program Files x86" which is where 64-bit programs actually belong. I also made sure (during the installation process) not to check off one box that specifically states it will prohibit any GPU usage and voila! The long lost ATI-GPU has been found and is even being used - after I made sure to change BOINC and project preferences to allow GPU usage and download projects that require or may require the GPU's services.

The cc_config file is still MIA, but I don't care - at least until I end up with some problem(s) that only a cc_config file that can solve.

In conclusion apparently either uninstalling and reinstalling BOINC fixed my problem and/or reinstalling BOINC in "Program Files x86" did.

Anyways I hope this droning dissertation may be of service to anyone else with a similar problem. In general uninstalling & reinstalling buggy programs is often the quickest and easiest fix, at least if your OS is Windows.

How do you delete a posting? I decided to re-post my original message here under a new thread "ATI-GPU not found"
