My Computing preferences: for SixTrack and Test4Theory:

Disk and memory usage:

Use at most 542 GB disk space

Leave at least:

0.001 GB disk space free

(Values smaller than 0.001 are ignored)

Use at most 100% of total disk space

Tasks checkpoint to disk at most every 60 seconds

Use at most 100% of page file (swap space)

Use at most 100% of memory when computer is in use

Use at most 100% of memory when computer is not in use

my computer

Number of processors 8
Coprocessors NVIDIA Quadro 2000 (961MB) driver: 27536
Operating System Microsoft Windows 7
Ultimate x86 Edition, Service Pack 1, (06.01.7601.00)
BOINC client version 6.12.34
Memory 3325.58 MB
Cache 256 KB
Swap space 6649.45 MB
Total disk space 148.24 GB
Free Disk Space 113.99 GB

Hmmm ... what else could be wrong?

Hmmm, nothing IMO, except isn't giving all memory-resources
to BOINC, a little too much, Windows has some Services and Processes
, too
, which also need memory resources.

Imagine what happens when you start using your computer with all
memory resources assigned to BOINC, Windows can't use it's memory, swap-space
and the entire disk-space available, a BSOD is what I would expect!?

Trying to avoid this situation, I made a ~250GByte Disk-Partition for
BOINC (6.12.34; 64bit) only, on a third (1TByte) (system;SATA II) hard-disk. But any (system) hard-disk will do, even an USB =/> 2.0/3.0 disk
should work.
Also, 8 threads, but only 4 GByte system memory, leaves 0.5GByte DRAM
for each process or thread, using 8 GiG, on my I7(2600) host and running a
memory hungry simulation ends up using 7.6GByte RAM!

Answer is a bit late, but still applies ;-)

By the way: Wishing all a Happy, fortunate and healthy 2012.
