I am participating in the BBC Climate change experiment, running BOINC Manager 5.4.9.
The estimated time it will take to do one set of calculations on my fastest machine is nearly 3 months, and about 5 on my slowest machine.

Wise up and break the calculations down into realistic sizes, so that more people will actually finish the calculations.

3 to 4 months is a ridiculous time to spend on a single calculation.GL

Job done!

your not going to re-install XP after a motherboard change, you are mad......mad I tell you

I have done this when going from the DFI NF4 SLI-DR to teh eXpert but these are the SAME chipset and I still debated it

I would DEFINITELY re-install XP when performing a major motherboard change

the only conceivable way to avoid this would be to uninstall all your drivers, then use something like \"drive cleaner pro\" to rid yourself of the \"junk\" left behind and try it

I suspect you will have issues as the registry will be bloated full of crap

If you want 2Gb of ram go for 2X1Gb sticks

4X512Mb is hard to get running right on the AMD64 platform as Mike said

And with your 4400+ PC\'s what sort of secs/TS are you getting per core?

On one box, two Models @ 1.92 s/TS; on the other, 1.90 and 1.93 s/TS.

Much of the difference has to do with parameter mix. Before the global restart, the first machine had two at 1.91 and the other had two at 1.92.

The machines are similar except for memory. The first has Kingston HyperX 2-3-2-6 1T running to spec. The other has Corsair XMS 2-3-3-6 1T running at 2.5-3-3-6 1T, best I could get without manually resetting voltages (which is more than I care to do). No CPU O/C.

(Oh, different brand but otherwise similar low-end video cards.)

Built a similar box for a friend but with Kingston HyperX 2-2-2-5 1T running to spec. If memory serves, her times were both at 1.90, but I won\'t swear to it. (One Model might have been @ 1.89.) I\'ve been given to understand that A64 X2s, perhaps all A64s, like fast memory.

HTH.

A bit OT but, what the heck, it relates to calculation times...

Had five P4 HT boxes, from 2.8 to 3.4; three remain. I was an Intel-bigot for hadware because I thought they crunched floating-point better/faster than AMD. It was probably true once upon a time. Now? AMD might have a slight edge. Also, I think the AMDs use less power, hence a bit quieter, than Intel boxes of equivalent power. So, I now also have three A64 X2 4400+ boxes designed to crunch CPDN (good MoBo, low-end Graphics card, good low-latence memory), have Win32 XP on one, Win64 XP on the other two -- and SuSE 10.0 64-bit across the board. (I\'m very pleased with the X2s; two currently running TCM in XP and one running Seasonal in Linux.)

Lots of info on the net. Here is a good place to start: http://www.tomshardware.com/
(Don\'t let the \"busy\" home page turn you off; there\'s a lot of good stuff buried in there.)

Hmmmm. Might be some hassles going from Intel to AMD.
BOINC looks at things like that, and this info gets stored on the servers, as well as in some of the files on your PC. client_state.xml at least.

It would be best if you made a backup of the entire BOINC folder, even if somewhere on the same hard disk.
BOINC may decide to allocate a new computer ID, as the original one is associated with the Intel processor.
But you\'ll have a backup if it ends up in a mess, and you can yell for help.

I think that I\'d use both \"Suspend\", and \"Network activity suspended\", (both in the menu), before making the change over. Then select \"Run always\", with the network still off, and see what messages I got, with special attention to the computer ID, and anything else near the start.

Yes, backups are a great idea. At one point last month I was making a backup every 12 hours, until I got past whatever the problem was. For a while, I didn\'t know if my middle name was \"Backup\", or \"Paranoid\".

The only problem with an automated backup, is that BOINC MUST be exited before the backup, or else the files will get out of sync. And there\'s at least one \'lockfile\'.

This limits how much of the CPU will be diverted to the graphics thread when it is running.
