Hi all, Just to let you know that I have successfuly upgraded my PC to a new 950D dual-core for some more BOINC crunching power. XP did need to be re-installed, but it all seems fine right now and I am happily BOINCing away!! Thanks for all of your advice and help. Regards, Neil.

... You have the option of merging computers in your account info for any given client that you run. I\'ve merged Intel into AMD and vice versa previously and had no issues (though I still have an AMD 2500 floating around that won\'t merge for some reason). It seemed that needing the same computer name (ID) was necessary. Hope this helps you get your credit merged onto your existing rig.

... I wish I could merge them with active machines. Also a while back I was able to copy the boinc dir to a new computer change the xml files with an old Computer ID and it would take the place of that old computer. A few months ago it stopped doing that. Was there a reason for that change to?

Go to Your Account, on left of this page, and click on Computers on... View, click on Computer ID then, at bottom of the page, Click to merge. You\'ll be given self-evident options to merge the machine IDs. (It always keeps the newest one.)

The merging uses the descriptions of the computer to see if they are the same. Yours aren\'t, because one is \'described\' by BOINC 5.8.8., and the other by an earlier version.

The CPU type is one of boinc\'s major descriptors of each computer, so unless you replaced the old CPU with an identical one, boinc would consider it to be a different computer and you wouldn\'t be able to merge them.
