Memtest86+




and how do I unhide my computer, and when would anyone be looking into it?

You unhide your computer by going into your "preferences" page on this website and editing your personal preferences. You will not be giving access to any personal information by unhiding them. Feel free to click on my name at the left and see for yourself exactly what will be shown. The only thing that unhiding your computers does is lets people see some basic information about your computer, but most importantly to us is it shows the work units you have crunched recently. For instance if I am sharing the crunching of a wu with you, I can look at your past results to get an estimate as to how fast your computer returns results to know when to expect mine (ours) to be validated. But in this case, we could probably be able to look at your computer's results and tell you exactly what to do to fix your system to be able to crunch work units properly.Otherwise it would be nearly impossible. Once a work unit is uploaded to us it disappears from your computer so you could not copy the results to here so we can look at them. And with your computer hidden there is no way we can tell exactly what results you crunched to be able to look at them from here. There are millions of results on the system at any one time and it would be imposible to search through even a small percentage of them for the work units you crunched. If you unhide your computers the information is right there in front of us within a few mouse clicks.(I know I don't have that many results here to show but that's because my main crunching is done on the beta test trying to get the new enhanced application tested and ready for here.) As I said, feel free to look at anyone's computer you please. You will see that no personal information at all is given out, but it will make life a whole lot easier if you ever need help and it will also help trying to figure out problems with other's work units. Again another example, I am running Linux and I crunch a wu that gives problems. You are crunching the same computer and the result also gives problems but others do not. If I can look at your computers to see if you are running Linux also, then it may be a problem because we both are using the linux version of the program and te others are not.(Thinking beta test here, but the principle is the same) However if I see that you are running an entirely different system that would rule out a problem particular to a certain type of system and I would have to look somewhere else for the answer.

I also have this issue, one of the reasons I stopped using BOINC for a long time. I've decided to give it another try, but the same results occur *every* time my computer does work.

I have received NO credit, and no one seems to have an answer as to why every work set has an "unrecoverable error"

...makes me want to give my poor computer a break....again.


I notice you're using a Pentium 4M and I'm assuming this computer is a notebook. Some notebooks don't have adequate cooling and the excess heat can cause computational errors.

Have you tried using the Prime95 stress test and/or MemTest86?


Ah, yes, it's a notebook. I didn't realize overheating would be a problem since my house is usually cool. What's Prime95 and MemTest86? Sorry, I'm not very computer savvy. Thank you for your reply! :-)

The programs you mentiopn test your computer and memory for problems. I see some of your returned work units have access violation errors which sounds like it may have to do with your memory timings. However it could also be the cpu overheating or some other problem. Running the two programs mentioned will check your computer under actual operating conditions to see if there is a problem. For instance the "memory test" your computer does at bootup will tell if you have definately bad memory, that can't be read or written to at all, but it can't tell if it fails to read and write consistently when running at full speed. The Memtest program OzzFan mentioned will check this under actual working conditions. The other program tests the cpu and other parts of your system in the same way.
BTW, this exact problem happened to another person just a few weeks ago and it was found that his memory access speeds were different than what they were supposed to be. Don't remember the specifics, but when he changed his memory timings his computer started crunching perfectly. The memtest program will help you in this. Run the program and change the memory timings until you get it to run as fast as possible without producing errors. (If it is found that it really is your memory in this case. It could be something different.)

I'm getting a "computation error" on my work. I get an "unrecoverabble error for result ..." in my messages. This started about a day ago, and I cannot receive and process any work. Anyone know what's going on?
