first of all, which are the optimizations used in 5.40 because I\'m also running 5.15 on my E4300 and from what i can approximate 5.40 is 20-25% faster (maybe is the SSE2?)
second : one of my simulation just crashed (70%) http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=6335429 and could somebody have a look at it as I\'m afraid that this could be related to my oc\'ed E4300 (fsb 275) so i could back off a little bit
third : I\'m thinking about getting a quad core, so when i\'ll change the motherboard (chipset) and the cpu, could i resume the runnings with my new cpu from the same HDD

Most likely not without an OS reinstall. The chipset will be significantly different, along with the Hardware Access Layer, and several other things. M$ is not very good about this.

Plus M$ will want to reregister itself.

What you could do is take a backup of the full Boinc installation (when Boinc is shut down), and once you have the new system running, copy over the backup and install Boinc to exactly the same location.

As long as you\'re using the same operating system it should work OK.

As Pooh Bear says, when you\'re upgrading your system you may need to reinstall windows.

update... the 5.40 improvement over the 5.15 is ...1.79 over 1.86 sec/TS
although the 5.40 uses around 33% more memory

The main difference between 5.40 and 5.15 is that most of the disk activity (to temporary files such as .aswap) is now done in memory rather than to disk. So it uses 100MB instead of 70MB, but on the other hand only does 5% of the disk writing that the original did (you can see this in task manager/processes if you show the appropriate columns).
