What? No credit for these:

Why?

Is this your computer? ID 11651

It seems the first work unit does not exists. Yoyo may tell more about that. The other three work units were aborted because of a computing error caused by your computer. You only get credits for valid results.

There are various reasons why computing errors occur. Do you overclock your CPU? Often overclocking the CPU leads to computing errors.

I would guess that your Maschine ran out of memory. You have two Cores, and only two GB of RAM.
The ecm WUs use up to 1GB of RAM each...

That is not that critical. I also have a duo-core CPU and only 2GB of RAM. If the machine ran out of memory the ECM-WU will pause and wait for memory and not quit with a computing error.

The problem ist that ecm WUs only use the high memory demands in their last phase.
If BOINC start two at the same time (only using little RAM, and therefore not a problem for BOINC as enough RAM is available at that time) those will reach the high RAM phase simultaneously...
I lost many WUs exactly this way... Thats why I upgraded to 4GB...

Yes.

No. I also have a huge CPU cooler and a fan.

Thanks.

Only two? Two gigabytes is a vast amount of memory.

Thanks.

Not for ecm with two cores both running ecm WUs.
I have reached peak levels of RAM usage of over 3 GB, when two ecm WUs reached their last phase at the same time...

As yoyo told us (in this german thread) the big ECM workunits could call for (up to) 1,5 GB in phase 2/Win32. I upgraded to 4 GB in the quad system to cover just "normal" situation with four workunits within a RAM wasteful operating system like Vista, in the end 6GB should be well enough for quads.

@laguna
32-Bit or 64-Bit ?

I upgraded to 64 bit Ubuntu and 64 Bit Vista to use the whole 4GB.
(Actually at first I had left the old 667MHz RAM inside to have 6GB, but for better performance I dropped them).

Ok, thanks guys. Maybe I'll buy at least 2 gigabytes of more memory quite soon...
