Credit and cpu performance

(moderation:
Why is my granted credit so much lower than my claimed credit? also, does credit actually mean anything. and i dont know much about computers, but i was wondering if my computer is performing up to par.

Credit and cpu performance
)
Hm, your granted credit on this Workunits was lower because your claimed credits are for some reason far too high. And when other people claim less (normal) credits you also only get that normal ones. But that workunits still were from the S4 Science run, the new ones you have now and that you only will get from now on (maybe some old in the next 2 weeks or so but mainly the new ones) are different, they will take you longer and you will from now on get exactly the credits you claim.
And credit doesnt really mean anything, its only some kind of... points you get for doing work, you dont get anything for it its just a bit for competition and so....
and the performance... hmm seems somehow not to be too good. Im wondering a bit about: Memory 190.98 MB
Measured floating point

Measured floating point speed 675.41 million ops/sec
Measured integer speed 1299.75 million ops/sec
These numbers are very bad for your processor speed. Are you overheating and the processor is automatically slowing down? It's amazing you get good results, but some of the new processors are smart enough to slow down and not let overheating bother it.
RE: Why is my granted

Your claimed credit would be much closer to your granted credit if you upgraded your BOINC Client to the recommended version.
Seti Classic Final Total: 11446 WU.
RE: Measured floating point

You can disable the Thermal Throtling ( I don't remember the right name ) on the most BIOSES. Doing that your processor will stay at the top speed even if it's thermal sensor tells to slow down to preserve the cpu integrity.

P.S. I had that problem with my DualCore 3.0GHz running @ 4.5GHz, Now I'm running @ 4.2GHz and the temp reading is about 61 centigrades in full load @ 1.3875 Volts.
So my computer is

So my computer is overheating? How can i cool it down, just turn it off more often? will running less programs make it cool off. i dont want my computer to die b/c its too hot.
also, you said my computer isnt doing very well, could that be because i always leave itunes playing music? that should make processing wu slower right?
RE: So my computer is

Hm, a little bit but that shouldnt be much. And its hard to say if its overheat or any other problems with your hardware or software, hard to say....
Download Prime95 ( http://files.extremeoverclocking.com/file.php?f=103 )
open it and start "Torture Test" in one of the menus (turn off boinc before) and look if it runs some hours without errors, then you can see if your hardware runs stable.
RE: RE: So my computer is

I'm with Metal... prime95 will give you an ideia if your system is stable or not, also, I don't know your processor type, but I could improve my cpu temperature removing the Intel Stock Heatsink ( 75 Degrees Celsius at full load ) to 61 using a Zalman CNPS9500 ( I think that is the top 3 in today market ).
Best Regards,
i used prime, i only let it
)
i used prime, i only let it run for 5 minutes, but it said no errors. later ill let it run for a few hours.
Ideally you should give it
)
Ideally you should give it 24+hrs on each of the three tests since each puts a different peak stress on the system. If you're running dual core/HT you'll need to start 1 instance per logical core and set the afinities to have each on a different one. Also, for the one that maxes out memory use, you'll need to scale it's size downward to avoid hitting teh swap file and rendering the test meaningless.
Be sure to monitor you system
)
Be sure to monitor you system temperatures with something like SpeedFan whenever you seriously stress your computer. If you are worried about thermal throttling it would be best to keep an eye on temps to see if they are what are causing your poor performance.
Like Dan says, Prime95 needs to run for a while to ensure system stability. In the 5 minutes it ran on your system it could not complete one loop of the test, this means that your computer didn't have time to heat up and get to its max temperature. Give it at least 8 hrs, but like Dan said the longer the better, start with the 'large FFT' test as I find it generates the most heat. If you system passes the 'large FFT' test move onto the 'Blended' test, as this will now stress your RAM as well as your CPU. If you were to run the 'Blended' test first and fail, you would not know whether your CPU or RAM caused instability, always try to eliminate variables when testing the stability of you computer. And remember to take your time; rushing through something like this tends to only make more work down the road.
