1) Message boards : Cafe MilkyWay : Unable To Post In Number Crunching ~ "No Credits" (Message 63353)

Post:
Looks like you are starting to validate now, sometimes you get matched with a wingman that does not get the same exact result so the project sends the work to a third to verify which is correct!

Happy crunching,
Steve

Post:
You have not been getting work for the LHC - SixTrack project because they currently do not have an application that will run on Darwin / MAC.

Please take a look at the Applications page ...

If the version includes ati or nvidia then it is GPU
If the version included mt then it is multi-threaded (cpu)

Win7 x64, BOINC 7.0.64, All projects selected
I've since changed my selection back to BPR5 only.

Thanks,

7) Message boards : Number crunching : 7950 GPU core low frequency while crunching WUs (Message 58147)
Posted 6 May 2013 by Snow Crash
Post:
I use Trixx for my GB Windforce 7950 and it works quote well. At 1.25v I can get my core up to 1250 without error or invalids, and if I use an agressive fan speed (80%) I can keep temps ariund 56-59C.
8) Message boards : Number crunching : Why such high GPU requirements? (Message 58136)
Posted 5 May 2013 by Snow Crash
Post:
I could be wrong but the only relevant data I can find shows that it would actually take longer to process on your current GPU than your CPU.

9) Message boards : Cafe MilkyWay : UOTD is stuck AGAIN!! (Message 34932)
Posted 30 Dec 2009 by Snow Crash
Post:
I would like to add that my Milkyway preferences are not being stored reliably. Now and then they will return to default and sometimes the changes I make to a "location" profile go missing.
To have Milkyway ignore my preferences and try to have it's own way with my PCs is not what I was expecting.
10) Message boards : Number crunching : GPU Overclocking (Message 34802)
Posted 23 Dec 2009 by Snow Crash
Post:
Does MW benefit most from OCing the shaders like F@H and GPUGrid or should we set up experiments to see what kind of increases we get from core and memory also? For reference I have a GTX285 doing about 31K ppd and am wondering what I can do to get the most possible out of it.
