You also need to point BOINC to the new data directory on the Ramdisk. I always uninstalled BOINC and reinstalled it with the new settings, though there may be an easier way to do it.

I believe Yoro, it's personal preference.
What I did was to click on no new tasks
Then when they had all run out i deleted boinc and
reinstalled it choosing advanced options and changing
data path to my Ramdisk. (as per Crystal pellets instructions)

TY so much CP, I now have 3 of my 8(HT) cores running (due to
overheating cores and lack of water cooling)
sounds like a nuclear power plant gone bad...

SekeRob,
If I go forward with my RAMDisk project I would like to get BOINCTasks for before and after comparison. How would I go about getting the software?

Another question: Would it be possible/feasible to run one BOINC Manager in RAMDisk e:\ (Program AND Data Directories) for CEP2 and another in c:\ (Program AND Data Directories) for everything else?

I think that the attempts by you guys to speed up CEP2 thrughput by using a RAM disk won't have much effect, except at the startup of each WU when the program uncompresses the input data into multiple subdirectories containing zillions of little data files.

I don't see much HDD LED activity on my machines that are running CEP2, except at this startup period. I think that the bottleneck may be in the o/s due to it having to manipulate all of these files in its disk cache. I just posted on this subject in the DSFL Forum here: Re: 64-bit app on the way?.
-------------------------
[OT] @Jack007: Temps in the 60s on a 2600K running only 2 cores definitely seems wrong. If you pull the HSF off, inspect the mating surfaces of the CPU heatspreader (metal lid) and the heatsink, checking that all but a small amount of the paste has been squeezed out. If you are still using the awful standard Intel HSF, perhaps one or more of the nylon hold-down pegs has popped out, or something around the CPU socket is stopping the heatsink from descending fully onto the CPU.

On reinstalling BOINC: You can just reinstall it, but things sometimes go wrong, so I strongly recommend making a snapshot copy of the BOINC data directory first.
But before you do so, fully shut down BOINC. If you have it installed as a service ("protected application"), shut down the BOINC service. On Windows 2k/XP, do Control Panel > Admin Tools > Services, select BOINC and click Stop.
If there is a problem after the install or you have moved the BOINC data directory, stop the service again, copy your backup files over the new data directory, then start the service.
Changing from a 32-bit BOINC to a 64-bit one or vice versa may be different to reinstalling a client of the same type.
Sometimes I have found that BOINC won't start up properly after the reinstall. Sometimes your precious tasks appear briefly then all disappear or they won't start. A 2nd BOINC install has always fixed this for me. [/OT]

I use RAMDisk mainly to save writes to my SSD. The performance gain is minimal, but I have the extra memory sitting there anyway, so why not use it. I doubt that my SSD would fail prematurely without it, but if it did, I would lose a lot more time than it would take to install the RAMDisk. The main question for me is whether the PC has a backup power supply. If not, then I wouldn't bother with RAMDisk.
